You can't go wrong with any of the roots style superchargers including Whipple, Edelbrock and Saleen as they all give you similar performance inmprovements. I like the Edlebrock because it is different and looks nice and stealthy under the hood

 

OK, that's it, I've decided... Cover me boys, I'm going in!!

 

Good! You going to install yourself?

 

If you don't feel it there is something wrong, that's all I can say, even under moderate accel I can tell, putting you in the seat. It's not all that often that I go WOT anymore since I just don't need to. With the bypass (I have a Saleen) you can drive like it's not even there, I drove though crappy snowy roads not a problem at all.

 

The GT500 wasn't a WOW difference? That seems surprising.
