I take you have silent choice because of the term closed exhaust- this will not cause a piston to melt down at 4000 or 5000. If no one knows what the problem is nothing is going to be fixed- I have an idea of what your problem is- built many of supercharge motors- call me...

It's great that you are willing to talk to Ken and help him with his problems.:D But why not post what you think the problem may be??:confused: Maybe others can benefit from your knowledge before they have a costly meltdown.

if it is too long of an explanation, and you are too busy(as many of us are) to post it, maybe Ken can post what you told him.

TTT... What's the latest?
