Watched C6 on the Dyno!!! results inside
Hey Guys... well Im back from carlisle... Only stayed Friday and left earlier today
I watched them put a C6 on the Dyno... It was bone stock with 15 miles on the clock
Callaway wanted to see what It put down first and it was the first of a series of tests they said they would do before they started moddin it.
It put down a solid 347.9 hp at 6,000 rpms and a nice flat torque curve of 348.6Tq, This was on a dynojet... And it was mighty hot out. about 89*
Right after that a Z06 stepped on the dyno 2003 bone stock. Let loose 360rwhp and I forget the torque.
Gotta love corvettes! I have videos of the C6 on the dyno... I cant host them though... If someone could do it for me that would be great

Those numbers are closer to what I hoped the C6 would do. Somebody needs to get 5K miles on one quick and post some numbers. Maybe this thing will do 360/360 broken in.

I had my silver 2004 Z06 on the dyno at Carlisle this past weekend right before the C6 of Lance Miller went on. My car is bone stock with just over 2,000 miles. My numbers were 360.5 rwhp and 347.4 rwtq. In defense of the C6, as has been noted, this car only had 15 miles on it, so it should certainly do better with more miles. Of course when Callaway gets done with this particular car, it'll probably put down huge numbers. Actually, if my calculations are correct, 348 rwhp equates to about 400 hp at the crank, so the C6 is right on the money for horsepower. I think the LS2 will be a great engine, with plenty of potential for increasing power.

StealDads67,
That's a great handle, and if my Dad would have had a 67, I would have stolen it too. Thanks for the compliments about my dyno run. I was hoping for around 350-360 so I'm real happy with 360.5 rwhp.

Please send me the video of my C6 on the dyno, I'll be happy to post the video for others to see on our website. Feel free checking out what we've come up with thus far: Click here for the Carlisle Callaway Corvette Project Car!
You can email me the video whenever you have some time: Lance Miller - email.
Thanks,
Lance

The factory numbers for the C6 (400hp) seem to be spot-on though.

Don't know whether the 4L65E is any different, though.

With the performance axel, the drivetrain is accelerated faster, and thus the mass of the drivetrain itself becomes a bigger factor. Force = mass x acceleration.
The mass is the same with perf axle and without, but since the gearing is lower, the acceleration is faster, and thus the "force" required to make it accelerate is also greater, and that's less force that actually makes it to the wheels.
Yeah it is nonlinear, the amount you lose to the drivetrain and rotating assemblies actually increases as you increase power at the flywheel. This is why dynos are run in higher gears-- if you ran in first gear, you lose a much higher percentage to just getting the drivetrain spinning.

So the swapping from the 3.15 to the 3.42 on the C5 results in an approximate 10 HP loss at the wheels because the 3.42 is less efficient. But because the 3.42 is a higher torque multiplier, acceleration is improved.
This is why the A4 is dynoed in 3rd gear (1:1 ratio) and the M6 is dynoed in 4th gear (1:1 ratio.) This minimizes drivetrain losses as the 1:1 ratio is the most efficient.
The proof is in the pudding. Time and time again the early A4 C5s would dyno 286 with the performance axle and 295 with the base axle. This has also been observed by those who change their rear end gear.
It would appear that the M6 C6 loses 13%, as shown by several dynos.
