Edmond,
That is with 1-5/8" headers and 3" dual exhaust and no cats.
Dominic,
I also find it interesting that you picked up mph going from 12.8 to 12.2.
Once I get it to 12.8 AFR I will try going between 12.2 & 13.0 for the best time.
Cheers,
John

Yeah usually the best A:F ratio to shoot for is 12.5:1, depending on the car, you will usually find the most power between 12 and 13. Fatten up the fuel a bit and you might get some more power out of her.

Xram/AFR heads and 2 TBI units. He's had very similar results as I have. I would guesstimate picking up another 15-20 rwhp dropping the AFR from 13 to 12.2. Again, it'll depend on the combo of heads and cam but its worth a try since the worst that can happen is fouling the plugs, unlike going the other way.

Dominic,
If you are correct about the afr 13.0 to 12.2 then I would be right where my goal was when I started the project. I was shooting for 360rwhp. Here's hopin for you being right!

I may of missed it, but John you ZF6 or 700R4? Curious, Do you think the 1 5/8 primary tubes are slowing you down or no? Most guys have 1 3/4. Anyways, 360rwhp would be cool, congrats.

BLACKZ51,
I have a 700r4 with a TCI 3000 lock up stall converter.
I don't know if the headers are holding me back or not. Eventually I will change them as they are just cheap hedmans.
I still think I can get the 360rwhp just tuning it.

gotcha. 360rwhp is around 440-450 flywheel i think......that's good.
