Here the nose of the gal is being removed for access for the supercharging process underway.

[ View Pictures ]
The plenum as originally designed being removed along with the valve covers for much needed modifications as the supercharging process continues to move forward.

[ View Pictures ]
During this process items such as the rubber intake manifolds/compliance fittings are discarded and in their place will be CNC machined billet manifolds designed to be sealed with serviceable laser cut base gaskets and o-rings to seal the manifolds to the underside of the plenum.

[ View Pictures ]
Once the modifications to the plenum and the valve covers has been completed all pieces will be treated to fresh powder coating.

[ View Pictures ]
Here are the valve/Vanos covers after the modifications were completed and then the assemblies were powder coated and now ready to be installed.

[ View Pictures ]
The installation process underway.

[ View Pictures ]
Ready to have the coils dropped into place and then the coil cover installed. With this portion of the engine once again sealed it is time to begin the engine bay modification which includes numerous items including the relocation of the oil filter and the power steering reservoir over to the passenger side (left hand driver models).

[ View Pictures ]
Here the power steering bracket. The reservoir was previously located on the driver side shock tower however it is now located next to the ABS control module on the passenger side. In addition to the relocation an alternate power steering reservoir (also an OEM BMW part of the same style ) will be used however the nipple locations are different.

[ View Pictures ]
Here is the initial fit of the Supercharger's CNC'd and anodized mounting plate.

[ View Pictures ]
Here is a picture of the DSC pump in it's OEM location being prepped to be relocated from the outside to the inside of the frame rail to create the necessary clearance for the Supercharger's intake and air filtration system.

[ View Pictures ]
The process of relocating the oil filter housing is underway.

[ View Pictures ]
The initial fitting of the assembly along side of the relocated power steering reservoir.

[ View Pictures ]
The new mounting brackets ready for final detailing before final installation.

[ View Pictures ]
The oil filter housing permanently mounted on its new brackets in the final location. The next phase will be to run the new plumbing and relocate the wiring required for the oil pressure sending unit.

[ View Pictures ]
The new spark plugs and coils have been installed so the final covers are being installed.

[ View Pictures ]
With the top end buttoned up and the custom CNC machined billet intake manifolds in place the process continues its forward movement.

[ View Pictures ]
Here the SC'er has been put in place for the first time for the purpose of confirming the final location of the system's by-pass valve location before completing the welding and then sending the lower plenum out for powder coating.

[ View Pictures ]
Here Greg is completing the welding process required on the lower plenum. This process included the installation of the by-pass valve neck assembly as well as the closing of a few OEM drain holes as the means to create a sealed assembling for the supercharging of this gal.

[ View Pictures ]
here is the lower plenum set in place with the fabrication work completed and the by-pass valve installed. The next step is to have the lower plenum powder coated.

[ View Pictures ]
The process of installing the remote starter button is underway.

[ View Pictures ]
The remote starter button installation moves forward. The OEM tray that once housed the cigarette lighter has been modified and the push button plate has been fit. Now the plate will be sent out for powder coat and then final assembly.

[ View Pictures ]
Here the patterns are being cut in preparation of the insertion of Mylar panels under the hood.

[ View Pictures ]
Here is the DSC pump in the OEM location just prior to the relocation process.

[ View Pictures ]
Here is the DSC pump now it its new location. The purpose for this is to open up the area left of the frame rail in the lower area for the locating of the MAFs and the air filter assembly.

[ View Pictures ]
Out with the old and in with the new widescreen along with a MK IV DVD based navigation system.

[ View Pictures ]
Here we are simply making room for the new widescreen to be installed.

[ View Pictures ]
Here the widescreen in installed and the surrounding areas are ready to be buttoned up.

[ View Pictures ]
Here the system is being run through a series of test including the operation of the navigation system which appears on the screen.

[ View Pictures ]
For those of you that have a E39 M5 with the early screen and the CD based navigation this is truly a wonderful upgrade and the process of converting is relatively painless.
Here the mandrel bent stainless steel tubing used for the relocated oil filter, power steering, and intercooler system is ready for installation.

[ View Pictures ]
Here are several of the completed pieces ready for final installation including the likes of the carbon fiber intake tube, the custom air filter adapter and filter, and the intercooler circulatory pump.

[ View Pictures ]

[ View Pictures ]
Here the relocated starter button is ready for final installation.

[ View Pictures ]
Here the custom stainless steel bungs and tubing adapters required to feed the relocated oil filter assemble are being completed.

[ View Pictures ]
Here the newly fabricated pieces have been set in place and XRP's HS-79 hose has been connected as the means to confirm fit in preparation of final assembly and the subsequent installation of the super charger and the component overlays that follow. The HS-79 hose is best suited in this application because of it's extreme design characteristics such as larger ID and smaller OD when compared to other brands of #10 hose as well as it's ability to resist kinking (meaning sharper radiuses are doable) as well as the long term service life when used in this type of application.

[ View Pictures ]
Here the AutoMeter gauges have been inset into the custom fabricated pillar gauge mount which was wrapped and stitched in to place using OEM interior trim material. With the satin finish bezel and aluminum face these gauges have a finish look that coincides well with the OEM gauges and trim.

[ View Pictures ]
Final assembly of the plenum now configured for the supercharger is underway for the last time now using the custom cut throttle body gaskets between the face of the throttle body and the base of the custom CNC machined manifold plates.

[ View Pictures ]
Here is the underside of the custom CNC machined plenum manifold.

[ View Pictures ]
Here is the upper side of the custom CNC machined manifold with the sealing o-rings installed.

[ View Pictures ]
Here the plenum is being put into place for the last time including all overlays such as the velocity stacks, charge cooler, etc.

[ View Pictures ]
Here the plenum is completely installed and plumbed; the gal is now ready for the supercharger to be put into place and the carbon fiber pieces to be installed.

[ View Pictures ]
So you have considered installing gauges on your pillar post? Here is an example of the rat's nest of wires and tubing that needs to be feed through an area with very little room.

[ View Pictures ]
The installation process well underway.

[ View Pictures ]
Mission accomplished; the new custom pillar cover with the integrated AutoMeter gauges has been successfully installed all that remains is the tying in of the wires and plumbing to various data collection points.

[ View Pictures ]
Here the center of the dash has been reassembled complete with the updated OEM wide screen integrated with the latest OEM DVD based navigation and the custom "Starter Button" integration has been completed. The center console panel and armrest assemble will remain out until the final wiring has been completed and tested.

[ View Pictures ]
Here the gal is beginning to come into her own as the final assembly process continues. Certainly there remains much in the way of detail work to do as the process unfolds and yet for most this is yet another very exciting stage of the project.

[ View Pictures ]
Something worth sharing; there was extreme difficulty removing this pan because it had been removed earlier and they elected not to use a new OEM metal pan seal but rather what must have been a tube of hard setting sealant to both correct a previously damaged seal as well as to prevent leaks. This pan seal requires "NO" sealant as it is a compression seal placed neatly in-between two nicely machined surfaces. The problem with the removal after sealant such as this is used is the fact that the pan is thin along the edges so no prying could be done; the entire sealing surface had to be methodically cut so as to release the pan and yet not damage the machined surfaces. Furthermore the sealant could have migrated into the pan itself and caused significant problems throughout the dry sump oiling system. These gals have "MANY" needle size orifices and could have easily been plugged then causing even greater damage. So the moral of the story is follow the OEM procedures for R&D or do not do it at all. As one such as example; the factory does not use sealants in certain areas for a very good reason.
Here the lower pan has been removed to facilitate the installation of the supercharger drain line. You will notice that the XRP HS-79 hose are presently hung up with a bungee cord to keep them out of the way for this process and then once the supercharger drain line is in place these will be placed back in their custom stainless steel holders that are located under the pan.

[ View Pictures ]
As the gals make their way through Area-51 they are treated to everything from basic tweaks to some of the most extreme performance options imaginable, exquisite attention to detail, and finish work that will forever set these projects apart from the masses. Regularly you can hear it said "long before we care how much you know we want to see how much you care"; and care we do which is fortunately further supported by how much we know. Here the underside of this custom Carbon Fiber hood is being fit with custom Mylar inserts for both looks as well as heat deflection.
Here the process of installing the custom Mylar inserts is well underway however this could happen only after the initial material patterns were created.

[ View Pictures ]
Here is how the process looks once completed; stunning and truly a compliment to entire engine bay.

[ View Pictures ]
Here the custom stainless steel tubing is being put in place to verify final fit prior to being installed for the last time. This gal is getting very close to having fluids pumping through her.

[ View Pictures ]
Here you can see the last of the relocated fluid transfer lines have been installed. The blue lines are XRP's product as are the primary oil transfer lines as mentioned earlier during this project and the #4 steel braided supercharger oil feed line. The A/C compressor had to be removed one last time during this process so as to properly secure the line with the custom stainless steel brackets.

[ View Pictures ]
Here you can see all of the custom relocated fluid transfer lines installed with the A/C compressor back in place. The lines have all been secured with custom stainless steel brackets that look good, secure the lines in a manner so as to protect them over time all while affording ease of service as the years go by.

[ View Pictures ]
Here you can see the supercharger's oil feed line in place.

[ View Pictures ]
Here the OEM front bumper is being modified for the final fitting of the heat exchanger and the custom grill is designed both for great looks and to protect the heat exchanger core from road debris.

[ View Pictures ]
Here the modifications to the OEM front bumper have been completed.

[ View Pictures ]
Here the modified OEM bumper has the reinforcement set into place so that the final placement of the heat exchanger can be determined prior to the fabricating of the custom stainless steel heat exchanger mounting brackets. The installation of the bumper once completed is an OEM with only one exception; the two large securing bolts will now be inserted and secured from behind the bumper whereas originally they were accessible front within the front of the grill.

[ View Pictures ]
Here the heat exchanger is mounted on the OEM reinforcement now ready to have the fluid lines fit into place prior to final installation.

[ View Pictures ]
Here is the custom billet upper radiator hose coupler. It has both the thermostat and grounding provisions for the electric fan incorporated into it.

[ View Pictures ]
Here is the custom water fill neck assemble for the intercooler system.

[ View Pictures ]
Here is the heart of the AquaMist water injection system ready to be installed.

[ View Pictures ]
As with every project there are always unique twist and personal touches. One such personal touch with this project is the integrating of a dual tone exhaust system. These pieces were designed as OEM Lamborghini exhaust valves however are now being made a part of the dual tone system specifically for this gal. So as to remain true to the project's name "Stealth Mode" she will retain an exhaust note similar to OEM so as to be able to traverse even the most conservative of neighborhoods with barely an eye brow raised however. Upon the flipping of a switch the beast within will be allowed to "Scream".

[ View Pictures ]
Here the custom stainless steel oil filter drain line is in the final stages of fabrication. This is required because by relocating the oil filter canister from the driver (left side) to the passenger side the OEM design is no longer applicable.

[ View Pictures ]
Here the custom oil filter drain line is being installed.

[ View Pictures ]
Here the final pieces of the custom stainless steel crankcase breather tubing is being installed.

[ View Pictures ]
Here the custom stainless steel front grill have been completed and is now ready to be power-coated. Once it returns from the power-coater it will be installed and securely fastened with small #10 stainless steel button-head socket cap bolts.

[ View Pictures ]
Here the custom mounting system for the electric fan is being fabricated. The OEM mechanical fan is removed for two reasons with the primary one being that if the OEM fan were to come apart it would be devastating to the carbon fiber and stainless steel plumbing pieces integrated as the result of the supercharger system.

[ View Pictures ]
The fan is mounted with a custom 3 point system and an OEM BMW isolated such as the one shown in the picture is used to eliminate transient vibrations.

[ View Pictures ]
Here is the primary fan support is nearly completed. The primary fan to support holes are counter sunk so as to eliminate concerns up next to the radiator core.

[ View Pictures ]
Here are most of the pieces of the puzzle slowly being completed in preparation of the final installation.

[ View Pictures ]
Here the primary support has been mounted to the fan.

[ View Pictures ]
Here the fan and the custom mounting system is being mounted to the radiator.

[ View Pictures ]
Here the lower isolated mount setup is being prepared for installation.

[ View Pictures ]
Here the fan and the custom mounting system is completely installed except for the OEM fan shroud.

[ View Pictures ]
Here the conversion has been completed and the radiator is ready to be installed back into the gal.

[ View Pictures ]
Once the right front inner fender liner was removed we now have access to the OEM windshield washer reservoir which is required to integrate the AquaMist water injection system.

[ View Pictures ]
Here the OEM windshield washer reservoir is being removed in order to integrate the custom feed/draw line bung into it.

[ View Pictures ]
Here is one of the many cool pieces during the water injection installation process. This particular piece was created over a year ago when Richard; the owner of AquaMist and I were addressing a specific need on a Z8. I wanted to integrate a water draw line off the OEM windshield washer tank and after numerous chats this pieces was created by Richard and his team. It has now found its way onto the E39 M5 as well.

[ View Pictures ]
Here the modification to the washer reservoir has been completed and is now ready to be reinstalled.

[ View Pictures ]
Here the OEM washer reservoir is installed and now the system's feed/draw line in being installed into which an AquaMist stainless steel micro filter is incorporated too.

[ View Pictures ]
Here the AquaMist pump; the heart of the system is being fit into the front bumper reinforcement.

[ View Pictures ]
Here is one of the last custom stainless steel tubes fabricated so that the final installation of the intercooler, crankcase breathing, and oil separator systems can commence.

[ View Pictures ]
Here the custom stainless steel mesh grill now powder coated has been installed for the last time using small #8 stainless steel button head cap bolts.

[ View Pictures ]
Here is one of the custom wiring harnesses fabricated during this super charger conversion process. This one has already been tied into the DME compartment and is now ready to be run to the respective component. The harnesses are all incased in an OEM style mesh wire sleeve for looks and to protect from chaffing.

[ View Pictures ]
The custom oil filter drain tube that was completed earlier now has an #6 AN fitting and cap installed so to keep it from dripping and causing an oily mess once the oil change has been completed.

[ View Pictures ]
Here the oil separator's assembly is being completed so the system can be installed for the last time.

[ View Pictures ]
Here the oil separator is being fit into place to verify that there are no clearance issues to address before it is permanently mounted. It is at this stage of the conversion process that space becomes extremely limited.

[ View Pictures ]
Here the oil separator in installed and the initial plumbing has been completed.

[ View Pictures ]
Here the custom stainless steel tubing is being fit back into place. This custom stainless steel tubing is for the crank case venting, the intercooler, and the oil separator systems.

[ View Pictures ]
Here the custom stainless steel tubing is being hand fit, trimmed as needed and the rubber hoses are being installed all for the last time.

[ View Pictures ]
Here all of the custom stainless steel tubing for the intercooler, the crank case venting, and the oil separator systems have been installed along with all of the required rubber hoses tying it all together.

[ View Pictures ]
Here the core support is being fit back into place.

[ View Pictures ]
Here the systems such as the power steering lines that run into the front cooler, etc are all being put back as OEM.

[ View Pictures ]
Here the nose of the gal appears ready for the front bumper and the heat exchanger...however.

[ View Pictures ]
Here the front shroud that covers the AC condenser and creates directional air flow through the kidney grills needs to be modified so the heat exchanger can fit properly below.

[ View Pictures ]
Here the modified shroud is ready to be installed for the last time.

[ View Pictures ]
Here the nose of the gal is back in place. At this time a few details need to be tended to and then the front bumper cover is ready for the final installation as such the conversion process has taken shape and now it is time for the numerous detail items and personal touches as requested by the owner to be completed.

[ View Pictures ]
Here the AquaMist pump has been installed and will have the plumbing and electrical tied in once the front bumper assembly is back in place.

[ View Pictures ]
Here the front bumper assembly which now includes the heat exchanger and the AquaMIst water injection pump has been installed as this gal gets closer to being able to stretch her legs a bit. The next item being changed are the lower OEM running lights. We are installing the later version that have the optically clear rather than diffused lens. It will be during this process that we will also be incorporating the strobe lights that were previously installed which is another one of the many cool features of this gal.

[ View Pictures ]
Here is what the early diffused lens versus the late optically clear looks like when placed next to one another.

[ View Pictures ]
Here the process of installing the strobe into the lower front running lights is well underway. The small blue coiled item is the strobe light filament.

[ View Pictures ]
Here the strobe filament has been successfully installed and now the lamp is ready to be installed into the front bumper. The strobe lights inserted into the lower OEM driving lights are a component of a complete system of strobes now located in the front as well as within the rear OEM lamps. These are an extremely high intensity strobe with a high cycle rate (meaning flash rate) so when they are fired up give a impression similar to what one might expect to see if an under cover officer pulled up behind you or in this case you will likely see them as this gal is pulling away. Just consider for a moment being an under cover patrol person in an extreme supercharged BMW M5. This feature further adds to the gal's project description "Stealth Mode". If I were to speculate I would say that if this gal were to want a lane and flip the strobe lights on most folks would quickly move over and allow her by happy knowing that they were not being pulled over for a ticket. Now we are not sanctioning this system but rather sharing another personal touch that if used properly could be considered more a safety feature when compared to it's already truly cool factor.

[ View Pictures ]
Here the new optically clear lens version of the running light has been installed. You can see the blue strobe filament through the lens which will make it much more pronounced when compared to the original diffused lens.

[ View Pictures ]
The transformation process continues as she continues to get closer and closer to becoming a "Road Warrior" able to traverse somewhat under the radar in a "Stealth Mode" when desired.

[ View Pictures ]
Here the circulatory pump for the intercooler system is being installed.

[ View Pictures ]
Here the circulatory pump has been installed and is now ready for the final two hoses to be installed. The location is such that whether servicing a hose or the pump it remains easy to access.

[ View Pictures ]
Here the wiring; a combination of OEM as well as add-on harnesses that are required at the nose of the gal is being sorted and made ready for tying into the proper sensor and or device.

[ View Pictures ]
Here is the electrical brain trust for this gal. Within this area are the DME as well as numerous relays, fuses as well as centralized power and grounding points from which a great number of the gals systems are controlled. At the moment the picture depicts "Chaos" and this comes as the result of having to carefully unwrap all of the existing harnesses for access so as to be able to successfully integrate the new systems in such a way that when completed they appears as if there from the day she was built. As the result of this supercharger conversion there are several additional relays and fuses being installed for systems such as the custom electric fan conversion, the AquaMist water injection system and the intercooler pump. The goal once completed is to have it appear as if we were never within or made changes to this area.

[ View Pictures ]
Here the final stages of the custom carbon fiber intake tube are under way. During this phase the custom machined supercharger connecting collar and by-pass sleeve will be bonded into placed.

[ View Pictures ]
Here the custom machined supercharger collar and by-pass sleeve have been hand fit into place and the bonding process is underway. We use heat to activate the custom Hysol formula as created by Loctite for us specifically for this process.

[ View Pictures ]
Here the heart of the custom intake system has been assembled. A slight modification is made to the pair of MAFs and then they are connected to the custom fabricated aluminum intake pipe with high quality cord reinforced silicon sleeves.

[ View Pictures ]
Here the custom intake assembly is ready to be connected to the completed custom carbon fiber intake tube.

[ View Pictures ]
Here the custom intake system is assembled except for the custom air filter assembly which will follow once this intake assembly is installed in the gal.

[ View Pictures ]
This customer had the custom remote starter button installed as a part of the supercharger conversion process as such the combination cigarette lighter and accessory plug normally available in the center console had to be removed. It was as the result of this that we elected to install an alternant accessory plug under the accordion style door located within the center console for items such as his cell phone, portable PDA, etc. Certainly this has been done by others; including our self however the goal for us as always is to have it integrated and not simply installed. In addition we want to make sure that the item installed poses no future service concerns. Most of the accessory outlets that we have seen installed by others use a couple simple self tapping plastic screws which over time "will" come loose and even worst are those that we see installed using little more than double sided tape. To properly install the accessory outlet it takes a bit of work however the results are more than worth it. When driving down the road and blindly inserting the charge plug to your cell phone the last thing you want to concern yourself with is whether the accessory plug is going to come loose and fall out.
Here the accessory outlet has been installed.

[ View Pictures ]
Here you can see that in order to do so properly the compartment is a dual wall construction so we had to bore a couple access holes so as to be able to insert the stainless steel #6 Nylock nuts and then secure them to the allen head socket cap screws.

[ View Pictures ]
Here you can see that the tail end of the accessory outlet is allowed to protrude out the back so that the fit under the accordion door remains clear and easy to operate.

[ View Pictures ]
Here the MAF harnesses are being extended. This is required because of the non OEM location of the custom intake system to which the MAFs are mounted. As is the case with most things we do this to the extreme level as well. During the course of the extending the two MAF harnesses a total of 9 wires are inserted. Now it would be less expensive and far easier to simply run 9 pieces of wire any color or as we see "ALL" the time all one color which would function just fine however if there was ever a problem it becomes a technicians "NIGHTMARE" to trace the problem. For the most part all of the wires used for extending and modifying harnesses are the exact same colors including gauge and trace lead color where applicable as OEM. In rare instances if we were not able to locate the predominant color with the appropriate trace lead color we simply retain the predominant color. During the fabricating and modifying of the various wiring harnesses we use only the Factory recommended procedures including the use of only OEM wiring connectors. BMW has made it clear that they do not want these wires soldered because of the concern for secondary resistance, corrosion, etc.

[ View Pictures ]
Here the assembly of the MAF harnesses is in the final stages. One of the sets shown has the OEM style braided one piece wiring harness wrap already installed. The braided wire wrap is for both esthetics as well and the protecting of the wiring harness.

[ View Pictures ]
Here the custom MAF harnesses have been completed and tested; the next phase will be to integrate them back into the gal's engine bay.

[ View Pictures ]
Here the custom carbon fiber intake system has been installed for the last time. During this process the secondary systems such as the supercharger's by-pass system has been plumbed as well. The engine bay now has the look of a mechanical marvel as well as simply aesthetically fricken awesome. At this phase all of the secondary harnesses have been completed and are being laid into place for the last time.

[ View Pictures ]
Here the gal's central processing department that maintains the likes of the DME has had all of the secondary system's integrated. The only item that remains is to band strap the three ground wires presently wrapped in blue tape. The band strapping of the bundled wires such as 12 volt constant, 12 volt switched, and ground is the OEM method as such we follow it. The yellow caps seen in the picture are those we installed after the integration was completed. All of the signals for the secondary pillar mounted gauges are now live as are the electric fan, the intercooler circulatory pump, and the Aqua Mist water injection system. Now we need to remount the OEM horns which will allow us to button up the driver side head light and then we can complete the detail work on the interior wiring which included the iPod integration as well.

[ View Pictures ]
She is getting very close to going home. At this stage the proverbial punch- list consists of only a few items and yet how they are completed will make the difference between another completed "Master Piece" or simply a project completed. I share this because often times people get anxious at this stage and become time constrained versus results oriented and all too often we see projects completed by others where this is blatantly obvious.

[ View Pictures ]
Here the custom upper radiator hose with the machined billet adapter for the electric fan's sending unit has been integrated and now ready to be installed and coolant added to the gal.

[ View Pictures ]
Here the supercharger's custom carbon fiber 1 into 2 discharge tube is having the custom machined Aqua Mist water injection bungs bonded into place. This is one of the last steps before this assembly is installed for the last time.

[ View Pictures ]
Here the custom water injector bung installation is completed and the discharge tube is ready to be installed.

[ View Pictures ]
Here the is the final assembly of the custom 1 into 2 discharge tube supported by all of the hand fit silicon sleeves is being completed for the last time.

[ View Pictures ]
Here the Aqua Mist water injections swirl jets have been installed and the quick disconnect "Y" connector used to bring the system together.

[ View Pictures ]
Here the final stages of the Aqua Mist water injector connections are under way.

[ View Pictures ]
Here the engine bay has been completed. The Aqua Mist water injection system has been primed and checked, the first round of programming has been completed, and all of the primary systems have been tested. The only remaining within the engine bay is the installation of the OEM fresh air filter assemblies.

[ View Pictures ]
Here the custom air filter and intake assembly is being installed for the last time.

[ View Pictures ]
Here the gal has both of eyes back in place. Add to this the front license plate and toll box sensor has been reinstalled.

[ View Pictures ]
Here the gal's heart has been fired and being run through a series of test prior to buttoning up the underside of the gal. All of her fluids have been topped up and a complete temperature cycling of the gal's heart is underway. We still need to mount the OEM horns and possibly a European style siren before installing all of the under body panels. Here the OEM horns have been mounted on a custom bracket and now the lower front corner of the gal is ready to be sealed up for the last time.

[ View Pictures ]
Here the gal is once again sitting on all four of her shoes. Looking and sounding great. Only a few minor details remain before she can go home and be exercised.

[ View Pictures ]
Here is the gal's heart being run in once again after all of the tuning has been completed. Here the primary securing strip that was punched out in a Strip-It machine is being fit to the lower spoiler in preparation of the final installation.

[ View Pictures ]
Here the primary OEM under the engine panel has had the aluminum 8-32 Nutserts installed and is ready for the spoiler to be installed.

[ View Pictures ]
Here the lower valance has been installed for the last time. On the lift it does not do the looks justice because when she is resting on the ground it appears that she is hugging it.

[ View Pictures ]
Now that the final installation of the custom lower valance has been completed the natural finish stainless steel fasteners were replaced with black powder coated button head cap bolts as one of the final details.

[ View Pictures ]
Here the secondary instruments are brought to life one last time for a through testing before the process of the buttoning up the interior commences.

[ View Pictures ]
Here the final wiring is well underway. In addition to all of the gauges and secondary systems being tied in we are also integrating an iPod interface during this process.

[ View Pictures ]
Here the center console cubby has been to include the accessory outlet, a secondary switch, and the iPod interface cable neatly tucked in.

[ View Pictures ]
Here is the iPod module neatly fit into place in front of the shifter.

[ View Pictures ]
Here the cubby has been installed for the last time.

[ View Pictures ]
Here the iPod cable has been extended out of the cubby as may be placed when actually being used.

[ View Pictures ]
Here the interior is completed; the wiring is finished and all but the aluminum trim on the driver side of the dash has been installed. The last trim piece is on it's was from Germany.

[ View Pictures ]
The following are pictures of the customer's final personal touch underway. He wanted the ability to have both a quiet (Stealth Mode) beast when traversing through town and yet once on the open roads also to be able to open her up both from a performance standpoint and an audible standpoint. After numerous discussions the system was agreed to and the various pieces acquired to bring it together. In this system's case we are using Lamborghini exhaust diverter valves as the primary portion of the conversion. They are a cast and stainless assembly as such should provide a long service life.
Here the surgery is underway. We began with a new pair of Super Sprint high flowing mufflers that are of a noise/sound level only slightly higher when compared to OEM.

[ View Pictures ]
Here the fabrication and welding portion of the process is well underway.

[ View Pictures ]
Here the assemblies are being welded into place as one of the final stages of the conversion process.

[ View Pictures ]
Here the assemblies have been completely installed and now all that remains is the connecting of the vacuum lines to the diverter valves through the vacuum reservoir and then firing up the control circuitry.

[ View Pictures ]

This is truly a unique Valvetronic system able to operate in either wide open or closed stealth mode. The best of both worlds.

Here the electric vacuum solenoid has been neatly mounted within the same area that the brake booster and master cylinder resides. The solenoid has been plumbed and the electrical connections made. In order for this system to work without the need for a secondary vacuum canister (this was a viable consideration because with the gal being supercharged she will likely be without vacuum much of the time) I converted the brake booster into a small reservoir as well. This was done by using an alternate OEM check valve in the booster and then using another OEM in line check valve. The vacuum source for the exhaust is a closed system so there are no concerns for brake degradation.

Here the custom exhaust by-pass system is being plumbed for vacuum from the electric solenoid to the two rear diverter valves. During this process the vacuum line was run inside the driver side fender liner and than all of the driver side under body panels were removed so it could be run to the rear protected from the elements except for the last few feet at the rear of the gal.

One of the items that this customer wanted was an easily accessible fire extinguisher within the car however after researching options we found that very little was offered for the E39 M5. As such we contacted Sam at BK Auto a firm that fabricates an extremely cool billet aluminum quick release mounting system for a variety of marquees with heavy emphasis on the Porsche and Corvette Club Sport folks. They agreed to work with us to design a mounting system that would work specifically in the E39 M5 as well. The following pictures are of the various pieces as completed, being assembled, and then ultimately installed with the fire extinguisher neatly tucked in under the driver seat within in easy reach and by design very quick to remove. Certainly the completed assembly compliments the project and yet it will offer ever greater peace of mind for the owner.

Here the switches responsible for activating the vehicles strobe system and the custom exhaust diverter system have been mounted. When activated each has a discrete led that glows keeping you aware of the systems status. When off the switch becomes completely black and blends with the dash and the interior.

Here the gals heart is completely back together and this gal is ready to be exercised. The supercharger conversion which included a multitude of new systems have all been neatly integrated so that as this pictures indicates; the engine bay has a performance OEM look to it and what is equally if not even more important is the fact that the gal remains easy to work on whether by ones self or the local BMW dealer.
