Just guessing...
You got it. The idea of the dump came up after the exhaust was already done and there were a limited amount of places it would fit without hindering ground clearance. Trevor was looking for mainly a sound change with it open which it surely does. Actually when open, it flows more than out the rear of the car, so it's reducing some back pressure as well. I didn't just stick it there, I looked at the flow path through the bends prior and tried to place it where it would get some directed flow from the bend just before it. Most ideal location no, does it work as intended, absolutely!

Those cutouts work wonderfully on turbo cars. I have one on my VR4 and with less back pressure the turbos spool up a little faster. Not to mention the sound change is fun in traffic.

This car is sick, love the detailed photos being posted up!

Yes. It did/does run but needs a few additional items such as a fuel cooler/etc.

Definitely runs! I'll allow Marcus and Trevor to release more details when they deem it time, the car is out of my hands though and doing well!

Indeed, only 16.8psi on E85, amazing what happens when you can properly control BOTH cams =)

I'd love to convert to E85 on my supercharged setup. Wish it didn't require a fancy new Pro-efi

What happens if he can't find a normal gas station? Will the stock ECU adjust?

interesting??? what happened??? a thread thread back shows lengthy work to get the pro-efi in and working.... what ecu did you swap too in the end...
its good to note that pro-efi DOESNT work with these cars, something just isnt right and they refuse to correct it....

its a shame this was kept so quite on completion....

Are you going to do anything cosmetic to the nose? Will you leave the air cooler exposed like that?

Pro-EFI just won't work the way it's setup from them. It could be made to work with some DME tuning but that journey seemed endless and the full potential of the dual vanos setup was wasted. After making our way deep through some business contacts, we came up with a solution, a very costly solution, however it seemed like the proper road to take once to this point. The factory DME is no longer in the car either. Instead a full standalone (not one you've heard of), plug and play setup completely contained inside the factory DME box, tuned via USB or bluetooth connection, E85 flex fuel sensor functioning, and is running nearly 100% of the factory functions. Some tuning/software/ECU updates are still in progress on the car and will be completed in Trevor's hands but the car is driving and running nearly 100% as stock, making great use of both Vanos and making some serious low end power on a stock S54. Just be patient, a little more time and I'm sure Trevor and Marcus will have plenty of video's and coverage of this Z4M =)

Intercooler is made to be exposed. It will be getting anodized black once in the hands of Trevor, perhaps a different bumper covering it but other than that it will stay as is.

A silly question I guess but I'm going to go ahead and ask anyway. Is that wheel horsepower?
