Wondering if timing chain skipped a few teeth, I might take the timing cover off to see if the sprockets marks match up on the timing chain.Khunts pull burnout run 300kw on 15 psi miss detonate and turn to sh*t at high rpms with less mods than I yet there car are fine,why did mine sh*t itself at 3500-4000rpms if that :banghead: 1500-2K job me thinks.May as well upgrade springs/ actuator while there at it. who in Melb to people recommend East/SE Melb to fix it.

Is there any way to find out definitively without pulling the head off?Tune got done on 15/11 by Bullet Performance Racing. I ran it on Pit Lane Performace's dyno on the 25th with the results below.

clark522 Donating Members 128 Member For: 15y 8d Gender: Male Location: Melbourne Posted 03/12/10 05:38 AM Share Posted 03/12/10 05:38 AM I think to check to see if a rod is bent they need to take the sump off? someone correct me if im wrong. Mine did the same sort of things yours has, half throttle at 30+ k's, hit boost, went bang and shut down, turned back on and the conrod had bent and a piston snapped. Good luck with yours though, hope its not that bad. Link to comment Share on other sites More sharing options...
