This dyno graph is rear wheel horsepower and torque. You have to take into account the drivetrain loss.

Hey, I heard the key to the LS7 power is the 48m TB and 26lb. injectors

Actually, they don't they usually turn out around 450rwhp SAE dynojet?

That's what I'm confused about. In the c6z section i repeatedly see stock z06s in that range but all the dyno graphs show 'dynojet' right on them

What's confusing?

This is a mustang dyno, don't they typically run lower and are the "heartbreaker" dynos???

Tom, thats awesome! Any chance you can get me a copy of my dyno graph?
Thanks,
Chris

EDIT: pulled up a nifty site i use alot Z06 Specs that says 505hp as well. what gives ? and oh yea...hi all :-P new member to the board

The factory ratings are at the flywheel. On a chassis dyno, the power is measured at the rear tires. So you have the loss of drivetrain etc. which drives down the hp number.

alrighty. after i posted i remembered most of the time they're advertise in flywheel hp. plus i figured the magazines would give actual RWHP instead of just saying "this is what Chevy said" but i guess not still, 448rwhp is no joke. i want a vette...
