Got my limit raised to 6k and have hit it a few times with no load on motor, like missing 3rd and the occasional 1st to 2nd flat change. (Need an excuse to rebuild it but it just won't die). Sees 5500 on a daily basis. yea, my old au engine had a wade 1645 cam and when it was supercharged I raised the limiter to 5900rpm, it hit the limiter atleast twice a day for 18 months with no failure... I think more investigating is needed mitch.. |

I think more investigating is needed mitch.. me and my work mate thought about the possibility of detonation? and as I took off from the stop before it happened was a big cloud of black smoke that came out of the exhaust Beaut XG wrote: mitchell g wrote: rained 6 hours beforehand, also I wasn't going to work I was picking a mate up on the way to work so was different the way I usually go If it was a different way then that's even more of a reason to be more careful since you weren't familiar with that way says mr trys to get his land cruiser sideways

in my opinion mitch, its a mechanical failure not a tune related one, nothing in the tune will cause piston to hit the valves..
its can only really be either a cam chain issue, cam timing, the cam it self, bad valve springs or not enough rocker/ lifter clearance.. |
