Ops my bad.
Well "bone stock" 212 at the rear.
Pulled the fuse to the PCM and reset the computer.
I got another 12HP out of it for a total of 224.
I have to scan my Dyno print out and post it up.
With like 85 thousand miles on it.
I thought it was kinda low but I guess 60HP lost through the trans and rear is not too bad.

Stock is 285 at the flywheel and a loss of 60hp sounds about right for the trans and rear end.
The car runs fine.
So I guess when they were putting your engine together the guy decided to give you an extra 50HP?

At the time of dyno, Im not sure if i was still running the hood intake or a stupid duck tape and dryer hose one lol, gutted cats and a lt4 KM and all free mods.
Trust me, car ran good.
After this i did hooker LTs and 1.6 RR and ran 12.9 @111mph
The 20% thing is also high for an m6 in my opinion.
Dyno jet BTW

I have a 97Z28.
Your car has a little more HP the me and it takes less HP to run through a 6speed.
I have an auto it takes more HP.
So I don't know what more to say on the mater.

Re: Dyno Runs
even on a mustang dyno i made 249, loaded to 3350. dynojets i made from 255-265
and when i say i was stock, i mean i was TOTALLY stock, i had just bought the car.
285fwhp to 212rwhp...your talking like 30+% driveline loss...unless you have a 5500rpm stall, TH400, with 30"x15" slicks with 8psi and a 9" rear....your car is not running right.

Re: Dyno Runs
if you wanna get technical, its like 25.614%..sorry for not taking the time to bust out a calculator to tell him his car is not running right, again.
btw, these cars are underrated as said before, with the power most people make at the crank, he would be in the 30%+ range.

Re: Dyno Runs
Well I'm believing that something is wrong with the car as well.
A4's due suck a bit more out of the HP, but not enough to justify your numbers.
You said 84,000 miles. Have you changed your spark plugs? Gone over your wires? Maybe the gas lines are clogged a bit, have you run any injector cleaner lately? How's the air Filter?
In my opinion something doesn't sound right. Very low numbers for a 97 Z28, even on a Mustang Dyno.
Let me know what the like is for your dyno once you scan it. Maybe that will help tell what is going on.
What Torque #'s did you put down?
