ryan, turbo its using is a custom PT74/76 DBB, on a 3.2l engine. so for a reference point, if ray made an easy 800whp on a PT76 why cant a bigger engine on a similar turbo put that power down??
note that the power is to the front wheels. see my Haldex explanation. AWHP is probably in the mid-upper 600 range. the Z06 is also lighter than the R32, steel widebody+ big wheels and whatever else it has adds up. take into consideration a STOCK R32 weighs like 3500lb.
for those interested in the R32
in car video, 20psi.
