16V dyno mash

16V dyno mash
The first dyno mash is ready. Apologies for the rather crude resolution.
Stealing this idea from refresh951. The few of us running 16V Turbo engines deserve our own thread. So keep em coming. Remember to post specs. I'll go first.
Spec
-3.0 S2, stock bore and stroke
-JE 8.0:1 compression (probably slightly higher due to decked block twice)
-Dry sleeves
-Piston squirters from 968.
-H profile conn. rods
-Custom intake (made by an idiot(not me) and a piece of crap. Will be changed)
-Lightly ported (done by the same idiot that made the intake, probably more harm than good done)
-3" exhaust
-Link G4+ Storm
-Comp CT4X-6467T4 AR .81
-Chris White 60-2 trigger.
-LS1 coils
-Sequential injection
Dyno done on waste gate spring pressure of 0.8 Bar. Torque peak is because of slight overboost

KSira, that engine has a lot of torque even off boost...do you have any positive manifold pressure at 2000rpm or is it basically breathing atmospheric there? Nice power without pushing much boost!

Spec
-3.0 S2, stock bore and stroke
-Wiseco 8.5:1 compression

I thought the "3 liter turbo registry" thread(the sticky thread second down from the top of the thread list in this section) already had all this.
