Who should be worried about this problem. What if we simply have an exhaust which increases boost pressure minimally? Kinda scary... Ill pay the 500 for precaution probably...

I'm buying the bolts as soon as Pruven gets them in, who cares what the cost to get them on is? I can afford it over the cost of a new engine.... (although if the motor went, the wife would HAVE to let me get it rebuilt ).

I didn't mean it was the race gas' fault. I mean that may have been the reason you wouldn't have detonation with the higher temps. Wouldn't the excessive heat/pressure that race fuel can handle before detonating make it easier to run leaner (and therefore at higher combustion temps) without noticable knock?
That was my reason for questioning. I guess it wasn't clear. I ask out of sheer curiousity.

My theory is that when you go over about 300 whp - thats when they start to strech - - when you get to 400 whp they strech faster
The black pruven evo has 345 whp and they were on the way out

What if you did not lean out the AF ratio with a S-AFC or other AF controller, you think this still woulda happened with 20 psi to redline?
I am sure a lot of you lean your AF ratios from the factory 8.8:1 (or somthing like that) to like around the 11s.

I think Al hit it - the bolts are just crap and they stretch overtime. The more HP you're generating, the faster the degradation process.
