Roots supercharger

[BowTie Eater 5 Liter]

Kenne bell makes roots type s/c's, the difference is power curve, the roots makes boost at any rpm, centerfugal has to spool up boost.roots are better if you want a driveable stang with LOTS of torque.
kenne bell is a popular roots type blower.
You should also look into an INCON TWIN TURBO KIT, it comes with 2 turbos, capable of 7-28lbs of boost, a complete fuel system(injectors, fuel pump, MAF, Custom chip,intercooler)for $4000, & nothing else to buy accept E7ZZ engine mounts. a turbo is free hp (uses exhaust gases to spin impeller, where as a blower uses the engine's power (crankshaft) to spin the impeller. a turbo set up for 10psi will Double your power. www.inconturbo.com
a turbo is a better choice(to me!), but either way wou will have ine rompin stompin stang!
