I'm pretty sure you don't need that valve cover breather and that intake you have on there is only sucking in hot hot engine bay air so that is going to kill power considerably. What kind of plugs are you running with what gap? Also what octane gas have you using?

Ditto! Is that intake new? That'* a lot of HOT air you're pulling into your throttle body. What about the filter? You really need a heat shield for it. Valve cover breather is purely cosmetic at this point.

PREMIUM ONLY!!!!! You're probably getting MASSIVE Knock Retard running 87. Due to excess heat from the supercharger compressing the air, anything less than premium will pre-detonate and your computer will pull timing. That Hot Air Intake is only compounding the issue. For now, just put back on the stock intake and fill that baby up with 93 if available - 91 MINUMUM. Don't drive hard until all that regular is burned off.

Custom made job. Do a search on "heat shield" and you'll see plenty of examples. Consider a FWI (Fenderwell Intake) to get the coldest air. www.intense-racing.com sells them. They come with a quality filter too. I'm not sure about that one you got now - looks like a knock-off K&N, which we have found are capable of HOLDING water.

FYI, it'* not necessarily the heat that causes KR, although that contributes to it.

The primary concern is the 'effective' compression ratio. On boosted engines, the ratio goes sky high at WOT. That'* the reason for running premium to prevent knock (predetonation).
