what size of blower do I need
#11
1471 will more than feed a 600" motor...PSI's are cool...but you really need to be turning upper 6's to 7000+ rpm to see any real advantage.

Why do you say this? If the carbs are right it won't ever load up, has nothing to do with the blower. Granted we could get into other issues, cam design, ignition, etc...but the blower has noting to do with it....

You will need to start by buying pistons first. I run 8.5:1 comp. on many of my pump gas supercharged packages. I would run a 1471 size supercharger for sure on this application with to dominator style carbs. Please feel free to contact me, I can give you the best pricing around on every component you need with our 50 years of business. (216) 398-8500. Thanks again!

the fuel i'm looking to run is good old lake powell 91, part water, part fuel, just kidding, over the years it has been pretty good, water sep, has stayed clean, here in utah, the best pump fuel you can buy is 91, I don't want to get into the octane booster, been there, pain in a--, I'll cut the timing back to 28 to keep things together. I am running an Imco 12" extension with a 3" rise, the scoop on the hatch is large, but not large enough to accomodate a 14/71 with a chiller, thats the only reason I'm looking to stay away from a cooler, I will give marv at psi a call as strip suggested, now single carb, or twin, where would you get them?

Marv is at www.boostdaddy.com not PSI. Also Dean Gellner can hook ya up, He's on the same page as were talking about. Give him a call also!!

I agree about talking with Dean also, but at 10.5:1 with a big blower turning that slow is not the ticket here...the fuel will stick to the rotors at slow speeds, idle.
Try an 8-71 at 2 psi. with 750's....91 will only support that.
Or your going to have to re-piston the for more boost.

Agreed, 8.5:1 with a big blower turing slow is what I was referring to.. like a 14 turning 5% under...
