i have a question its kind of complicated.
i just picked up a 86' gt and when i hit my second gear to 5k plus it seems to make the car bog and jump my rpms in a certain pattern verry irregular what would you guys think the problem would be?

Is it carbed?

FredP

fuel injected #30

i'm having same problem. Same set up 30#. I bought a new msd coil, i'm just waiting to put my headers on and drive it to see if it still does it. did yours backfire?

you probably have too much fuel going in with the 30# injectors. whats ur other mods besides the injectors?

piedraco

347, trickflow heads, cam, and intake, 75mm tb, 75mm egr plate, cai, 30# injectors with calibrated mass air, AFPR tuned to 32-33.5 psi at the dyno shop. it started bogging on me like a week after i got it tuned. my distributor is cracked a little bit on the bottom, I dont know if that affects it in any way. I have msd 6A with a rev limiter

what is your rev limiter set at?


what are your numbers? at which rpm s on the graph

piedraco

I pm'd you a couple of days ago asking for some advice on your set up. How are you making 402 rwph??? the best pass that I got it at the shopp was 340 with shorties, I have longtubes now So i should be making a little more. rev limiter is set at 6k. 5200 rpm I believe
