What I'm suprised to see is that TQ number being pretty much as high as the HP number. Isn't this car rated at 580/556? Assuming this dyno is fairly accurate with its numbers and not just reading high, that would mean either the car is putting down more than expected, or that the car has a pretty low drivetrain loss...under 10% loss with that TQ number. Is that even possible? Ford certainly seems to have underrated its GT and Boss...(unless it too has a magically low drivetrain loss percentage) so would be a nice suprise if Chevy did it here. I just wouldn't count on it lol.

It's nice to finally see some numbers!! The cool thing about this car is a pulley, intake, long tube and tune combo and we'll be seeing 600rwhp.

If these pulls were done yesterday, I can tell you the weather in the midwest was very good for making power. These things will be a real monster with some break in and minor tweaks. :-)

The max on the Mustang dyno sheet is 503 I believe...
Also, unless these guys are bound and determined to be suspect, the numbers are corrected. That means the cold weather is taken into consideration when plotting the power graph. What it does not take into consideration, is the fact that these are FI cars, and it's correcting for an N/A car, so give back a few percent based on that. Turbo cars always look overly powerful when corrected, especially 15psi plus cars. Still neat to see, as the GT500 gets the same treatment with the correction factor. Intake, pulley, and exhaust....575whp?

All numbers on dyno sheets are with SAE correction as stated, due to the prevailing weather conditions on the day, the uncorrected numbers are higher.

to everyone else stop complaining about the HP first of all when they advertise the HP and torque of a car they are talking about at the flywheel...not to the wheel dynos show what HP you are actually getting to the wheels |

My CTS-V just got done up at LPE on the same dyno and it ran 583hp & 583tq with an 8.66 lower, 2.55upper, ID850's, Kooks headers & New Era CAI. My baseline with Kooks headers & New Era CAI was 520hp & 497tq. Graham and the boys at LPE are at the top of their game, as always! |

they are just following in the footsteps of..... C6 ls3's, all LS3's, 2011 5.0's, and of course 392 hemi's. in spite of SAE certifications, they are all underrated by 20-80hp.
