matt, how did you fix the ignition break-up?Don't have the graph with me. But with the ignition breaking up so bad it shut off the dyno at 5000rpms I made 424whp/515tq on a DaveH kit [email protected] PSI. (should be about 450whp now that the ignition is fixed)
TT headgasket and 525cc injectors
Lexus AFM (trying to switch to a VPC if I can find one)
SAFC-II tuned about 11.7-and dropping to 10.8 at redline.
Graph can be found in my gallery page on the link below in my sig.
Stock base timing, 93 octane. I'm right at the edge of the timing and compression for my car. I've heard of people getting 14-18PSI depending on the turbo and the car itself on TT headgasket.Oh, wow, thats actually pretty good!
What timing were you running that you got 16.5 PSI with no knock? 93 octane right?
HKS Twin Power and NGK 3330 copper plugs gapped @ 28. I think my iridiums were the problem, as soon as I put the HKS on I basically lost 2 cylinders spark. Changed out the plugs and everything has been running good since. The old plugs were NGK Iridiums at heat Range 6 and I think the colder 3330s are helping a lot as well.matt, how did you fix the ignition break-up?
