Thanks TJ, can you give me the specifics on your Saleen S/C so I can do some research. Where did you buy it from?

Thanks again!

its not the supercharger persay that kills the gas mileage if you stay out of boost, its the larger injectors that you install and your tune.

Gas mileage will drop...but the car will run the same for daily driver...just had the power IF you need it or want it and the push of a pedal. Gas mileage wont drop THAT much at all if you put 39lbs injectors and stay out of boost. The gas just drains as soon as your step into the boost.

Superchargers help engines run and breath easier, so it will help your engine perform, even without boost...and if you get the intercooler, it will still push in cold air, again, even if your using the boost. All in all, its a great help for your engine, gas mileage will drop because of the different injectors, and it gives you the availability of huge power gains at the push of the pedal

bought mine from Underground mustang..got an incredible deal. I also invested in injectors, 90MM MAF, cold plugs etcJDM tunes..it has about 8.5 lbs of boost on a 3.6 pulley (2 sizes smaller than Saleen stock pulley) with smaller belt..to sum it up for all the additions plus installation it ran me about $5800...but that was with an incredible deal from UGM and an incredible installation deal...its a great SC: there are others that will give you more boost...Turbos are insane with boost if ya want it...personally I love my Saleen as it gives me the boost when I want it...and to echo Wally39..the passing power is freaking awessome....to hear that thing whine...>DROOOLL.....I have to go drive now...BYE...TJ..Just kidding...seriously...I love it...

So the 5800 bucks included someone else doing the install?
I tell ya, I've been reading so much lately that my freakin eyes are hurtin, I hate big decisions like this and I'm absolutely terrified of screwing up one heck of a nice car that I just spent over 27K for. Listening to these guys talk about throwing codes, modifying this and that during the install, breaking belts, and so on has me nervous.
Okay Okay, I'llquit whining.
I've noticed that some guys go with the centrifugal super charger versus the twin screw, is one better than the other??

whats the difference in roots style and twin screw type s/c's

ORIGINAL: cheftjpeck

the only sc I know of thats roots is Roush...which just from what I read is antiquated style and the potential with a twin screw is better as far as modding it...wheras a roots is limited...

If you can't sleep at night without a warranty, get the Roush like I did. I'm perfectly happy with 452 flywheel HP (with pully upgrade). And as far as being antiquated, the roots blower is the oldest but most reliable design, which is why most auto manufacurers use them in their stock set ups. GM, Mercedes, Jaguar and use them. They have the least moving parts and provide great boost at low rpm (think daily driver).
