Very slow time... why?

[Zex4g63]

How long are you power braking at the line? If you do it for more than about 3-4 seconds it makes your timing go negative. Did watch your logger when you do that? That might explain the bad 60fts. My GST pulls 2.0's all day long. Hope that helps.

interesting. I never knew that. But, no, im pretty sure it wasnt for too long. maybe 3 to 4 seconds max.

Well heres another issue you may or may not know. Everytime the car shifts the timing returns to zero and starts over. Meaning that when your car is at 7000rpm with 13 degrees of timing, the instant before it shifts the timing goes to zero, then starts building up again. I have made my best trap speeds when the car build 18-19 degrees in each gear. I'm not saying this is your problem, but that I think you have other issues that you are overlooking. Check and recheck, get someone else to double check. A second set of eyes often comes in handy.

DSMlink has a great feature that retains the timing through shifts on an auto which is great...You think maybe you have an exhaust leak possibly? Cause yeah you should be in the low 14s or high 13s even if its an auto.

so any followup info on this? im having the exact problem, car logs fine, boosts fine, i had a ton of upgrades should be hitting low 13s, and i ran a 14.5 =\

do you pressure check your manifold i dont know if you took the intake manifold off but maybe you have a leak there.

At .98v and no knock my car is incredibly slow. At .90 at 8-12 counts I run 12.2's on 91 octane. Run whats fastest, your knock light is not God.

Yeah, I know about the timing pull, but I dont think that would account for 2 seconds. No exaust leaks, and no boost leaks, and the turbo feels like its fast... but when I get my slip I discover it really wasnt that fast.

Is there anything that could be getting old in an auto tranny that would be slipping or something that could cause me to not be getting all my horsepower to the wheels? I have shift kit and end clutch, stock converter.

timing has a lot to do with it. you can loose from 50 -80 hp if you dotn have the right timing or you have knock. tuning is everything.
