It's all in the tune. If your compression is down to begin with, your engine is eventually going to 'blow' regardless if it has a supercharger or not.

Don't exceed 400rwhp and have your engine tuned by a reputable shop. Even then, you are guarenteed nothing but a hurt engine at some point down the road, so save your pennies and be willing to endure some down time and drop the cash for a stronger rotating assembly.

what type of car you driving? Cobra? 2005+ GT?

I dont think they make whipples for 2V 99-04's which is most of the people in this section. I'd either ask in the Mach1/Cobra section if you're a 4V, or ask in the 2005-2008 section as I doubt we can answer for ya first hand.

yea it should work fine, id say keep the boost down to 8 psi, get a great tune by a reputable shop and have fun, but further down the road get ready for a rebuild, but hell go for 10 psi and eat some vettes

Depending on the year of your car, you can get a Roush supercharger that doesn't not invalidate your warranty.

keep it under 450rwhp and you should have no real worries but i have also seen kids blow their 4.6's with 400 wheel so be careful and make sure you have a good tune
