They are 2 completely different types of engines especially when you consider the 5.8L's ability to make 650hp at 6,250rpm and 670hp at 7,000rpm, its gonna pull like an exotic on the top end. The LS9 is a better comparison because its hand built and forged high revving engine can handle the addition boost and abuse a larger twin screw blower like a 3.4L Whipple or 3.6L Kenne Bell. If they would of put the LS9 in the ZL1 and the 2013 GT500 never was released I would seriously be looking to find a dealer to take my 2011 GT500 on trade.

I'm now just thinking about waiting to see what the new gen 2015 GT500 will be, hopefully with IRS, Ti-VCT, DI, e85 before I get a archaic 13-14.
yep your right and then this happened ...


my buddy had to back his cobra boost off. he was at 18 psi. nothing but top end heat soak.. he backed it down to 15-16.. the 18 psi had a great bottom end.. that was is. it actuall made the car slower.

so comming out with 15 psi who cares.. 6.2 liter at 15 psi vs 5.8 leter at 15 psi = 5.8 fail.... I am sure that the ZL1 can be boosted at least 4 more PSI.. 1 PSI equates to about 20 whp..
