Ok here's the dyno of engine no 1 that died during an overboost to 27 psi.
This dyno is from when the engine was still in Markus' car.
495 rwhp at 1.3 bar (19 psi) pump fuel. Engine no 2 should be able exceed 500 rwhp at lower boost.

My 3.0L is in process. Depending on the economy, I might have it running sometime in 2009.
89 2.7 block
89 2.7 head
Andial/Mahle 104.5 turbo pistons
Arrow rods
94 968 crank.
TEC GT electrics
VRStg5 turbo still needs to be purchased.
I'll be assembling this myself.

like line boring m14 head and main stud conversion porting the oil drains .9/16 rod bolts and picturs of the crank we all get turned on my a turned crank

The biggest ones, AFAIK. They are also transferred to the racer. As a matter of fact it's now on it's wheels, waiting for a new paint.

In PET the pulley for the 944 S2 (M44/41) is labeled "vibration damper" whereas the one for the 968 (M44/43 M44/44) is labeled "pulley". Parts numbers are different
Might the 968 pulley actually have no impact as a harmonic damper given the presence of the dual mass flywheel ?

Regarding crankshaft failures, my crankshaft guy told me he has seen 3.0L cranks fail in racing applications. His fix is to grind a wide radius for the journals and nitride to help with surface stresses. He said with those improvements that the vibration damper is optional - I'm still going to run a S2 damper in my 968T race car!

I added a quick and dirty summary table in the first post, for the running cars. I'll update if people want to fill in their details and/or correct the mistakes.
