^^^That is a good point. If you car came with the "Powered by Ford" intake cover, you'll lose this too. Both kits are nice, both make gobs of power---just in different ways.

Any twin-screw/roots blower makes its peak boost(i.e. power) right off of idle (2k rpms).

Centrifugals (vortech, paxton, powerdyne, procharger) act similar to turbos, and the build boost higher in the rpms(i.e. the more throttle--the more boost). They make power in a linear curve. The harder you push the gas, the more boost you will make(to a degree).


Both are very streetable, it just depends on how you want to make your power, and how you are setting up your car. I have 4.10 gears, and the car is setup for the dragstrip---its easier for me to hook using a centri blower as they make the power higher in the rpm range.

Unless you are running wide tires or drag radials or higher gearing, I would suggest staying away from the t/s blowers, for as soon as you get into the power band, you will instantly roast the tires. Hell, truth be told, mine will roast the nittos 275/40/18--555 I run everyday as soon as I start to build boost(3300 rpm). So I guess it really doesn't matter either way. like I said, either way you won't go wrong.

All of the manufacturers make high quality, complete kits. I can highly recommend checking out brenspeed.com <-- Probably one of the best aftermarket support & tuning companies out there for late model mustangs.

I would leave it stock and then when Carrol Shelby kicks the bucketit will be worth alot more if you just leave it alone. If you wanted to supercharge a car I would have just bought a regular GT.

Oh, I forgot, you can buy a polished 'Shelby S/C' made by Paxton if you want to keep it all stock looking under there. You can then contact Brenspeed for a better tune. That's the route I'd go.

Thanks for the information. Since it is new I have decided to wait a bit. I just wanted to get information from the guys running them to see what was the way to go. Sounds like the Paxton or the version by Shelby may be best for me.

If memory serves I read in a mag that you can get the FRPP Whipple installed by shelby and the will record it as a Shelby GT S/C. It is sort of aftermarket but shelby installs it and documents the new config so it would still be correct down the road.

I have no idea what they would charge though. Might want to look into it.

the Paxton too....

^^^ True but I am little biased toward the whipple
