Is this a Good Supercharger?

if you have a 4.6 i wouldn't suggest it. our bottom ends aren't as strong as the 5.0 and you'll prolly end up up blowin a hole in your piston head and possibly throw a rod or something.
 
go to superchargersonline.com for a better price on that kit. Yes it will be just fine. I am running a vortech non intercooled kit at 6-7psi, dyno'd at 350rwhp and 355lbs of tq on a 95 degree day. Its a blast to get blown, GO FOR IT. but dont buy from american muscle or 50resto as there prices on superchargers is too high.
 
owen02gt why would you not recommend him to get this kit , under 10 psi he wouldn`t be close to braking his bottom end , maybe 385 hp , so his bottom end would be just fine !
