The car lost .5 in the 1/8 mile. The car was real lazy... 60foot off, 330 off, 1/8 mile off, and mph off. Check all quick things and all seemed ok. I turned on my oxygen sensor computer the last pass (1 in each header collector)........... 4.5 all the way down the track on Q-16. it feels ok doing burnout and tried a dry hop before staging all was good. Then when it launched it was dead... all the way just stated clearing up then shifted and back to lugging. The computer reads realtime O2's in the pits were fine 16-17 idling around and on 2 step in pits??? wtf?? So something is changing on the lauch ... or high speed bleeds start working???
WTF again??
car ran ok 5 days ago no prob

Re: What happened ...... car slowed .5
Have you checked the transmission fluid? How bout checking for a bad spark plug wire. What all have you ruled out?
Re: What happened ...... car slowed .5
Something simple like slipped throttle linkage ? I've seen that screw things up on several occasions...

Re: What happened ...... car slowed .5
sounds like what happened to my car last time out on the 4th pass broke the crank snout out I am assuming that the crank was twisting and throwing my cam timing off
but mine was a blown application
did you bump up to a higher ocatane gas maybe
