help picking a roush supercharger...

roush

Roush has a forum called fnsweet dot com...you will find all of your answers there...

Call JDM or Roush and have them answer any questions you may have about the single or dual belt FEAD systems. My understanding of it is that the single belt FEAD (front end accessory drive) uses one belt to run all your existing accessories (PS pump, water pump, alternator, AC, etc.) which puts more stress on the belt and may cause belt stretch. The dual belt FEAD uses a dedicated belt for the supercharger, which will give you more control of the speed the supercharger is driven and be easier on the belts. Someone correct me if I misunderstood Roush's information.

The Edelbrock and Roush both use the same Eaton TVS supercharger, so there should not be any significant difference in power potential. They are packaged differently, but same guts. I like the cleaner looks of the Roush over all the plastic of the Edelbrock. If you blow up your motor, your supercharger would not need to be replaced, unless something really bad happened. When they blow up it is usually a rod that fails, sometimes blowing a hole in your block.

Good advice to go to fnsweet.com too.

My Roush has a m90 on it...its a safe 435hp that can easily put out 500hp at the crank and the whole set up is 3995.00. No need to worry about blowing the motor. It may be a good option for you.

Haven't you been "about to pull the trigger" for 4 years already? Just pick one and do it. &%$!.

Well I'm glad you're going to be able to do it now. Be prepared for the perma-grin.

I'm biased but I'd go with the Whipple HO kit. Once you decide to go with forged internals you could upgrade the blower drive to a 10-rib (two choices now). It's pretty hard to miss with any of the kits except for maybe the Roushcharger (M-90) that doesn't leave much room for bigger numbers.
