Yeah, let us get the TV show out of the way and then I'll have some of MY personal time at the shop freed up to work on the issues. (plus I don't want any contagious virus around here that might infect an engine thats going to try to be blown up on prime time nationwide TV in front of 5+ million people)
Based on the color of the exhaust valves (as best I can see in the pics) I would say the EGT was getting up at some point, if not most of the time. A quick Len inspection on the heads will verify this as EGT elevations are very apparent. Can you post a pic of each spark plug's porcelin area as close up as possible??? What I want to happen would be getting the parts to Charles so he can get the cylinders repaired and to me so they won't slow us down on this end. I'd want to build and dyno the engine with carbs first and then have you arrive with the MS set up and gear to tune the engine in the new lab. In the lab I can monitor EVERY aspect of the engine and log it for future replays. Remember: Even a rich running engine can detonate with too much ignition advance!!! The LE 200 heads are VERY efficient, much more so than the 7440 heads you previously had, due to this one can expect lower than typical ignition advance values. Patch up your back up engine (I'll help with parts to do this) and run it while we put a rope around this current issue and tie it up like the greased pig it has turned out to be. It won't leave my shop without 20+ hours of run time on it and I might use it for the ignition shootout since it'll be here anyway and could use all the run time we can give it. It won't kick my ass. But I can't touch it till after we get the TV taping behind us. This post has been edited by Jake Raby: Mar 25 2007, 05:20 PM |
