Having a pair of 502 Mag's rebuilt and going to add a supercharger not sure witch way to go roots (871), Whipple or Centrifugal. If I go centrifugal it's going to be a Vortech, I like the fact they keep the stock cooling system. I want to make approx. 650 reliable Hp (looking for pro's and cons).

Are they carbed or EFI?

They are complete 502 mag's so they are EFI but thats easy to change now.

As you debate the pros and cons, take a look at our website, www.rtechperformance.com.

When are you going to have the EFI version out?

I've been running the whipple system for 3 yrs on my 454magefi on my 01 Daytona- can't say enough good things about it. Pm me, I can hook you up!

I had VERY poor luck with a whipple kit on a 502 MPI.
Unless they have worked out the bugs, I wouldn't recommend it. I have heard great things about their other kits though.

R-tech does have their act together as it appears to me, worth a very serious look.

I didn't realize the cooling system needed to be modified for a pro-charger. I'm evaluating systems too... what needs to be changed?
thanks

Basically you remove the water circulating pump, install a cross over and remove the thermostat. If you end up running a thermostat you will have to run some type of dump valve. Wette Vettte has a nice set up, thats what I used on my old boat.
