I have a 1999 F-150 4x4 with 82k on the odometer. I was just curious if anyone on here has supercharged there 4.6 and if so what is a good supercharger for these trucks. What's the gain. and what else would i need to do and what kind of investment would i be looking at

 

the gain is big, cost wise it depends on the kit and labor to install it. check out kennybell, ford racing and whipple's web sites for costs of some of the many kits out.

 

Kenne Bell has a nice kit that gives a lot of low end power,
