Not an E28, but same drivetrain, engine ...
This shows how capable our old cars are with a little bit of boost.
635csi with M30B35 engine, forged pistons, O'ring head, ARP studs, watercooled custom built turbo. Megasquirt II engine management in wasted spark.
Excuse the GPS location issues and speed reading issues, the internal GPS is bad on the iphone 3GS.

Awesome!! Finally a video of a setup like I am building with the approximate power I am shooting for.his kind of thing really helps with motivation!

The great thing about the setup is the reliability.
Adding some special (and super expensive) lock washers for the turbo to the manifold and manifold to the head did help a lot.

Ha! Corvette= point and shoot - that was like the most classic case of this.
I figured that thing would eat any time the road got straight- but you hung well with big corner speed... But there is always that long straight... Tough to beat one of those things.

Nice driving! That was fun to watch. I'd love to do a track day with mine someday.
thanks for sharing that

We use those at work. They are pretty awesome.

Thanks, I bought the Tomtom GPS adapter, I hope that the next video will be even better with accurate laptimes, split times and speed.
I can't wait to try it.

Intercooled?

What diff are you using?

by Bruno
The car has a front mount intercooler and the diff is a 3.91 rebuilt, polished gears and variable ramp (this is a big part of what makes the car amazing)

Whats variable ramp?

30-80 variable ramp: the locking of the differential varies depending on the torque applied to it.
So if you are entering the corner and exiting it, the lock on the diff is different.
This allows you to be extremely fast in corners, very important when you drive a heavy car.
The differential is also cooled, the 1/2 shaft is running a mechanical pump and an oil cooler is strapped under the chassis. Also very important as I have seen diff oil temp beyond 350F.
