With a horribly-slipping clutch, the car put down 300whp, and 275 ft/lbs on a dynojet 248C. Those specs are at the wheels (So like 358hp and 324 ft/lbs or so?) with a rubbing, slipping clutch. I didn't give the clutch enough break-in time and I don't think the pressure plate has enough clamping force. I used a Valeo 835101 single mass flywheel conversion kit that is intended to be a stock replacement.
Next week, my new flywheel should be here, and then I can change the clutch kit and give it a proper break-in (500 gentle miles or so before I beat on it).
-The new clutch disc is a Luk clutch from a 2.0d E83 X3. The friction material on the hub is Shaeffler/Luk B8080S material that is identical to the material used on Luk N63 twin turbo V8 clutches. The reason I used the X3 disc is because the hub has the same spline pattern as the Z4's ZF GS6-37BZ gearbox.
-new Pressure plate is for an N62 V8 engine (550i)
-new Flywheel is an OE Luk dual mass
When I have the new clutch setup installed and broken-in, we can find out what kind of power the car really makes :evil:
