We don't know why exactly. It was on the dyno making pretty consistant power and not experiencing bad knock or anything. A/Fs were in the low 11s on E85 and nothing crazy for timing. We would get a couple counts of knock on some pulls during spoolup sometimes, but it would go away once it got into the powerband. The car has been through some hell lately though with the intake cam being a tooth off and some other timing belt problems and fighting to get rid off all the boost leaks. It was on stock head bolts also, which might have just been the weak point(even though there are other Evos making more power on the stockers without problems). We did a compression test before the problem yesterday and then one today after the waterpump blew out last night and then numbers were the same.
