went to the dyno today
took my car to the dyno today and I was a little dissapointed, I only made
295 whp on 15 psi. Im running a precision 6262, Z32maf, jwt ecu, 72lb msds. The motor is a bone stock gtir motor never been taken apart I expected to be a little higher than that, AFR was around 10.8-11.2. Do these numbers seem a little low to anyone else? I was expecting to be around 340ish

What was your timing set too? 15 deg? might have not been enough timing.

Yeah that exactly what I was thinking, I know 15 deg is standard should it be set to 15 deg with my current setup?

It should be the same as whatever your ECU is programmed for. (plus or minus a few with actual dyno testing and timing adjustments being made)

For example, I am using a JWT ECU with 25* base idle timing. My distributor should also read 25* base idle ignition timing.

You can check either with JWT what your ECU is programmed for by sending them the program number or if you have a way of hooking up a PC to your car, by that method.

If you are on stock cams, probably 15* degrees.

Yeah I am on stock cams right now, Ill call Jwt and ask them but Im thinking it should be set at 15. I had to replace the distributor a while back and I may have moved the timing a little I will have to check it and see. Its the only thing I can think of besides running a little rich.

Note: I do not have a turbo. What I say may be right or wrong, it is merely a reporting of everything that I have read concerning the air fuels of a turbo car.

What I understand around here, you want a turbo car to run a little rich. Those numbers seem good to me, but I do not run turbo so the game and ideal is different.

I don't do snails.

Chances are, with stock cams, the base idle is at 15*.

Turbos are fun . Yeah it was my ride home so I did keep it a little rich, towards the end of the dyno it was dipping down into high 10's which is a bit too rich but like I said I didnt wanna chance it, everyone was suprised tho that it made that.
Ill check the timing asap and post back results mabe that will be the culprit. My setup should clear 350 with ease in the same boost.

i think with that setup you should be atleast hitting 350whp, i would double check everything boost leaks stuff like that, what size exhaust are you running and what kind of turbo manifold ?
