interesting car question...turbocharged

[Guest Anonymous]

ok, I was home last weekend and I wasa able to drive the turbo. Here is the problem: The car drives like a champ with an awwesome power band when its warm, but once I've been driving it for a bit and it is warm-warmish hot, then I'll give the pedal a go and it will jump feeling like a misfire, and only when I floor it. I can put a 1/4 - 1/2 throttle into it and it does just fine, but when I punch it, it does its little skip hop thing.

I would guess that it would be a timing problem.

What are you running for a fuel pump, how much boost and could you describe that problem better? does it go, studder, go? Any odd sounds? pinging? popping?

You recently fill up with gas?

I'm using a fuel pump that is overkill for the car. My duty cycle meter at no time excedes 75% and my A/F is dead on at WOT. I use 92....excuse me...91 octane fuel with one bottle of booster (good stuff). I run 10 psi boost. The car makes no funny noises besides the fact that it won't open up. It is fine 1/4 throttle to 1/2, but anything past that makes it feel like a misfire, no pops or anything, just as if a cylinder went dead...kinda halting...hmmmm

Doug,

Are you using the knock sensor from the ford efi? If yes then your probably getting your ignition pulled back, more I think about it the more I thinks its ignition related. How are you controlling the ignition, completely ford? You may want to check out a turbo ford forum and ask the same question.
