Huron Speed Single A/C V3 LS1 SBE

Thought I would post this up here just in case anyone was curious. The 2 pulls were with the cutout closed compared to open. Ignore the torque readings on the early part of the runs (tach signal issue). This was at ~7psi. I am a little bummed that it fell off over 6000rpm. My tuner said it might be due to the valvetrain geometry (high lift cam with stock rockers).

Here are the specs on my setup:

2001 Z28 M6 (~77,XXX miles, original)
Huron Speed V3 Single w/ AC kit
VS Racing cast 78/75 Turbo .96 AR
Precision 46MM Wastegate (9psi spring)
TSP 233/239 113LSA Cam
Dual Valve Springs
Hardened Pushrods
80lb Deka Injectors
495LPH Racetronix Pump w/ hotwire kit
Holley Fuel Rails -8 fed, stock feed for return
Boost Referenced fuel pressure regulator (58psi base)
Monster LT-1 Dual Disc Clutch
SLP Loudmouth II catback 3"
QTP Electric Cutout

Pretty happy with it. Big upgrade from the 365whp cam only setup I had been running previously.

That's a big gain for just opening the cut out

Cool build been waiting to see if someone would post up results with a ac kit. Many people have run more lift on stock rockers. Do you have a dyno graph for the cam only setup?
