Corvette C6 Z06 Dyno Numbers

Looks like wagz was right, just a big turd put out by GM. :cwm18:

I'd sell a kidney, a testicle, and anything of value I owned for this car. :cwm10: Those numbers are insane. Intake, exhaust, and a tune and you've got over 500rwhp. Throw a real cam in there and a tune and you're over 550rwhp. I see some very streetable high 9 & low 10 second cars coming with very little work done to them.

Nice fat power curve :) They said that they replaced some of the exhaust, though, so it would probably make a little less stock ...

11.7 AFR @ 7000 RPM in a 7 L engine would suck back the fuel (24.067 mL/s) ... In 3rd gear (125 MPH), that equates to 5.461 MPG :cwm17:

Good thing it has a high AFR at low throttle :)

I'd love to have one, too ... I don't know if I'd be pawning off body parts, though :p

Jmac, what are you talking about? The stock numbers are on there (441rwhp or something like that) and then the after headers numbers (487rwhp peak). They gained over 40rwhp and 50rwtq with just headers, so there is still much potential to be had there. And with Displacement on Demand fuel economy should be more than reasonable, along with the 6 speed double overdrive transmission, and the fact that no car runs the same AFR at cruise or part throttle as they do at WOT.

And you only need one kidney and one nut. I can do without for that bad boy. :)

I see ... I misread the graphs.

I know that ... that's why I said it has a good AFR at low throttle (just like the C6). About 15.9:1 according to my calculations (assuming half the cylinders are off). 26 MPG @ 48 MPH = 1.941 mL/s in fuel consumption. I wasn't implying that it gets poor fuel economy during everyday driving.

I'm already missing enough body parts :p I'll just steal yours when you get it ;)

Not true. Read the whole post and you will see that they truly gained 24-31rwhp and 36rwtq, though this is still a lot.

The first graph is the base line, with a warm engine) against the cool engine pull with a 30 minute cool down.


The second graph is 4 pulls in a row, 2 minutes apart showing heat build up and the effects of the heat on the power.


the temp on the 3rd or 4th after pull was about equal to the baseline pull, so use this information wisely.


In other words, don't go comparing the cool engine data with headers (483.5hp, 460.2lb-ft) to the warm/hot engine baseline (443hp, 411lb-ft). Instead, use the warm/hot engine data with headers (473.9hp, 447.4lb-ft or 467.4hp, 447.4lb-ft)

No DOD in any of the C6's. The architecture is there in the 6.0L, but its not implemented.

Guess they figure they don't need it when the Z06 gets 28mpg highway. :)

It stands to reason that between a bone stock car and a car with headers and tuning (to prevent the car from pulling timing due to heat, and with any halfway big mod tuning is a must to get the most out of it), that on a typical car once tuning software comes out the car would gain that much with just headers + tune. So headers alone might have been misleading. Good catch.
