Vorshlag BMW E46 M3 CSL - V8 Downforce Monster Track Car ("Chainsaw Massacre")

[Fair]

continued from above - last one!

But seriously though, the work done in this area by Ryan was over the top. What started with a Painless 26 circuit harness has turned into a work of art.



The main wiring panel was built onto a false floor aluminum panel in the passenger foot well. All of this is hidden under another panel, shown above right, for a clean look - and to keep feet away from wires and components.



Lots of components are hidden under the dash or elsewhere and everything is noted in detailed wiring diagrams, kept within a binder. We are using Deutsch Connectors and pins for every connection, except for a handful of OEM connectors. Ryan was ringing out circuits today, bumping windows and lights with a tester, and the chassis wiring is almost complete.

BRAKE INLET DUCTS BUILT

The front end on this car was made from a hybrid 1M / E46 bumper cover made by Duraflex in a fiberglass-like composite.



Some might not like the look now but once the front wheel fairings are built and the splitter installed I think it will make more sense. It fit the look the owner was going for, but didn't really have a great location for front brake inlets.



Early on in the project Jason worked with Ryan when he was mounting the bumper cover to show him where we wanted to pull brake cooling air from - a high pressure section of the lower grill area. The two outer openings were then utilized for twin oil coolers, as shown above left. The brake ducts were recently built and fitted to the triangular sections shown above right.



Sometimes you get lucky and the OEMs make a nice, tapered funnel that necks down to a 3" or 4" round section you can slip a brake cooling hose over, but not this time. We decided on 4" cooling to deal with the speeds and brake heat load this car should be capable of. Ryan made the outer panel then transitioned this to a 4" round aluminum tube for the hose to fit over.



He makes it look easy but there was some time and skill that went into these inlets. We will add the 4" hose after the final oil plumbing is completed, but room was left to clear all of that and for the route to the front wheels. The brake backing plates were made months earlier.

WHAT'S NEXT?

Whew, that was longer than I thought it would be! What's next? Well last week Corey and Louis from G-SPEED stopped by to measure the engine bay for their custom Motorsports engine harness they are building to fit a Motec M150 ECU.



With this mapped out they are building the harness now for delivery soon. The last bits of plumbing and chassis wiring will be tidied up and then Ryan will move to the front splitter, wheel fairings, and rear diffuser.



And the exhaust system is already being built as well. Gonna sound good, and will exit through the diffuser.



More soon!
