Ok so I suppose that makes sense. So basically a higher compression ratio is better as long as you use gas good enough to avoid "detonation"?

Reviving this thread...how loud is this supercharger: http://www.brenspeed.com/10-1607-b19332a.html
I know the M90 is outrageously loud and I was hoping for something that was maybe a little more subtle but still whines when I give it the beans. I know a few of you guys have this setup so opinions/testimonials/videos would be sweet.

I have almost 50K on my Brenspeed stage 2 (saleen), its not loud but when you are on it hard, there is some whine. A great system, when it comes time to get another Mustang, it will also get the Brenspeed treatment!

It looks like I would be able to retain my warranty from what their website says if I have it installed by them or a Ford dealer. I'm going to go ahead and assume that a Ford dealer is going to rip me to pieces with their install price and I live in SoCal so Brenspeed isn't exactly in my backyard. Do any of you know if they have a "branch" anywhere closer to me? This is one of the reasons that Kenne Bell was so appealing to me; their headquarters is like 5 minutes from my house. Too bad they are soo expensive and I wouldn't be able to keep my warranty as easily.

With the stock M90 setup, my 2009 was actually not very loud, I couldn't notice the blower whine until I floored it, and even then it was still reasonable.

I added the Roush CAI with the matching tune from Roush and that woke it up. The setup is rated at 460 hp, and it's now really screaming! It's loud but it's an amazing noise, part of the whole muscle car experience if you know what I mean. I wouldn't want it any other way.

I won't push the engine further though. For future mods I'm thinking about making the drive train more efficient, better breaks, better handling, etc, but I think I'll leave the engine alone.

Not sure how this compares with the 2010 which have a different intake setup than the 2009.

I only know of the one location and it would be a long drive! I will say I had a great time driving from Indiana back to Alabama, the car was a blast!! Good luck with your decision.
