Was it a dynojet or a mustang dyno?

tonydss

Pretend you could get 10-15 rwhp from pullies and a ported TB, that would be 375-380 rwhp. What exhaust were you running besides the jet-hots?

tonydss

cut out my own y pipe custom

were do i get underdive pulleys and what kind and who has them in?

Don't get too hung up on the ##'s. As long as it moves. You could always try another dyno for comparison purposes.

tonydss

ya asp is a 3 week back order

You can say that again. Mine isnt moving incredibly well, but check the bottom of my sig for my numbers.

I would say dont worry about the Hp and Torque #s. It has been said that the peak #'s dont win races, power under the curve do.

My 2001 M6 with only pacesetter LT's,ORY, Cutout, and SLP Lid, put down 329hp/347tq on a dynojet. Cam going in soon and will post back up. Ive been looking for some comparisons on here, power with mods given, and tuning comparisons.
Good thread!

tonydss

also i dynoed in 3rd gear was i suposed to do it in 3rd?or 4th i heard if you dont do it in fouth you lose 20 to 25 hp?!?

greekss

who put all this stuff in for you... sounds like you need to do ALOT more research before u mod your car anymore.... jsut for ref. my car '02 ss with mac mids an ls6 cam and cut out put down 359rwhp/362rwtq

tonydss

what are you talking about?!?! i did do alot of research and i figured i would have atleast 380 .. 365 in 3rd hoping 380 in 4th? what gear did you dyno in i have a m6

deetsnai

u need to dyno it in 4th, thats 1/1 ratio gearing, the computer might have adusted wrong to the gearing and messed up numbers.

also by research he meant that u should solve this problem before u start throwing more money at with mods

tonydss

It isn't that you wasted 70 bucks, it is the dyno shop that didn't obviously know what the hell they were doing. Your mods are about right for the car. I had people tell me I should pull numbers anywhere between 360 and 380 with a tune. I have a 216/220 114lsa comp cams xr269hr, long tube headers, off road y, flowmaster, k and n fipk, ls1edit, and a few minor free mods. My rear numbers were 361.8 and 362.9. But my car pulls hard all the way to 6500. I was hoping for a little more. I have been advised to put a cut out in it. I will do that, but also getting ls6 heads and a more aggressive cam. My goal is 400 at the wheels naturally aspirated.
