Nice polished Cosworth plenum.
BTW... Sorry if I missed this in another thread, but what are your impressions of the Cosworth plenum on this setup? I noticed from the dynographs that you guys aren't revving it up to 7000RPM (or more). Since it's a built stroker with your head package and the Cosworth plenum, why aren't you guys revving this motor higher?

We have tested it over 7000rpm before but it required another ecu due to the '05 G35 closing the throttle body at 7000rpm. The dynodynamics chart posted above is run to 6900rpm.

Had the same problem, had Sam at GTM reflash it so I can rev past 7500, also take the speed limiter and bump the idle. Best thing I ever did IMO.

I don't knwo which ATS triple carbon clutch he has, but the soft compound triple clutch discs won't hold at those power levels. You will need the standard or R compound, the 1350 pp, and it sounds like you will need the CCM (carbon coated metal) flywheel and pressure plates which increases torque capacity significantly.
