Kenne Bell makes supercharger for the 302 thats supposed to be real good- makes more HP for whole RPM range they say (other folks on forums). Website says 104 HP to the 302. www.kennebell.net
Vortech and Paxton make them too, but they are centrifugal types which only add power after 3000 rpms. A lot of street rodders have these too.
The twin screw SC'ers make great torque down low, but tend taper off at the top. The smaller centrifigual compressors will make great low end power as well, but for a Race engine, a Vortech YS trim or a Novi would be the better option (other than turbocharging) because they will continue to make boost throughout the RPM range.
Think about it this way, if the centrifigals dont make boost until after 3K RPMs, and there is absolutely no reason for you to shift before 5200, and you are at WOT, how often do you think you will stay within your powerband and above 3000 RPMs?
ther are alot of bolt on kits from summitracing.com (i know i mention them alot, but they are even better than jegs, and i can always find the stuff i need, even when i was building a 1000hp pontiac 455 for my bro in-law i got everything except the cam and crank from them.)
Originally posted by RoidRageOrangutang Hey Blurry, so I take it you're satisfied with the vortech? THey're more for speed right?
Sorry for the delayed resoponse....Yes I am very satisfied with the Vortech, it has worked out very well on my GEN 1 Lightning.
Don't take this the wrong way...for street races and towing, a KB works great, and I will put one one my tow rig after I pull and rebuild the motor.
But for racing (as mentioned in the original thread) this is where the centrifiguals and turbos shine.
You'd be suprised to see how fast a smaller SC'er compressor spools up with a very modest pulley combo...even below 3k.
