Here is the DYNO sheet Glenn :D
Nice numbers and plenty of torque (No drop off) on the top end. Impressive!

Looks good. Get the car tuned properly and you'll pick up a bunch more midrange power and torque.

Looks good. About all you'd want on a stock bottom end. Plenty of tq, ought to be fun to drive.

Had the car been dyno tuned BEFORE the IAT Sensor relocation? Or was it running the supplied Tune? If it had been dyno tuned.....what were the previous numbers?

Boost gauge was proved to be bad because the datalogging shows 9.5# of boost.
I cant explain the low torque, but can speculate it is because of the numerically high gear ratio in the car- 4:56 gears. Tall gears make a car faster, but historically decrease power #'s on a dyno.
I believe if the car had 4:10's, it would have made over 450hp and between 410-420 torque.
Car runs good, Im very happy.
The computer was adding timing over 4000 rpm's.
We ended up with a total of 16 degrees of timing in the final tune. We had 17 and 18 degrees in 2 seperate pulls and the car didnt make anymore power, so we left it at 16.
No pinging on the dyno or the ride home.
Flame away, I have nothing more to say. :pimp:
Nice post.

Very interesting.
I would call a 4.56 a shorter gear over a 4.10.
Very nice #s. :up:

Hey, Zack, don't you have it bassakwards?

I may be wrong, but believe a 4:56 ratio is (much) lower than a 4:10, which would be the taller ratio. Tall gears (lower numbers numerically) will allow the car to reach higher speed, if it's got enough power to overcome drag and other factors. So, the way I see it, the 4:56 rear should make the car quicker (more power) than the 4:10's , but at the sacrifice of top speed. :)
Perhaps that's what you said, but it's not what I understood.

Look at the dyno chart that Dennis listed last week on my car with 3.27 rear gears and a little more boost, I came in with 400rwhp and 444rwt, very close to the same set up. Tom

Nice numbers Zack. You going to pull out the 4.56's?

That car had 8.5 to 1 compression though. Totally different animal. But the gears sure do make a difference.

Are they SAE adjusted? You questioned my numbers so I had to hit back. All in fun though. Good job.

That is a fun-2-drive looking chart. I really like the relatively flat torque curve. Sounds like a safe tune as well. This will make someone a very fun and reliable car at those power levels.

Gears do not change dyno numbers...
Awesome chart thou, looks like good low end grunt and nice top end power.
