Go to the pettitt vendor forum. There is a pettit supercharger owners thread on there with 6500+ responses. There are a number of pettit supercharger threads on this site.

 

Does anyone know where you can buy the pettit supercharger?

 

Used from someone willing to sell one. They go between between 4k and 7k. Usually closer to 7k.

 

OK thanks man I figured that price anyway

 

Did you ever find one?


The power gains depend on the Stage you get. Stage II is recommended for non-technical types and daily drivers (like mine) - 5-8psi granting around 80hp power gain. No significant upgrades aside from the kit itself required (and a tune of course), although I hear it's a good idea to get an upgraded MazMart water pump, aftermarket aluminum radiator, no-slip 6-rib pulleys, and some other relatively minor cooling and exhaust mods.


Stage III gives considerably more horsepower/torque, but you'll need some heavy-duty mods like upgraded fuel injectors, fuel pump, and various other things, and your engine will not last as long with 11-13psi blasting through it from what I've read.
