F1-A or F1-R I spoke with Bob today about which blower i should go with to feed my new setup. LME 8.5:1 C/R 408 and AFR 225 heads.
Bob said that the F1 and F1-A are direct replacement for the D-1SC. The F1 flows 1525 CFM while the new F1-A flows 1650 CFM or something like that. I can't seem to find more information abou tthe F1-A headunit such as step up ratio and max impeller speed. Its not even listed on the Procharger Website.
As everyone knows the F1-R is the real monster here, but Bob said people have alot of custom work done to fit them since the external size is larger.
Im leaning towards the F1-R especially since the price between a F1 and F1-R isnt that big, but i would like to know whats involved in fitting the F1-R in there.
So any F1-A or F1-R F-body users out there? I would like to know how hard or easy to install these head units on the J-bracket. I mean did you have to drill new holes? Move stuff around? etc....
Thanks

Its really just how far you want to take the power level. If you want 1000+ hp, go for the f1R. If your only looking to make 800-900rwhp then the lower models are for you, but if you want room to expand for not alot more then id say go with the f1r if its not too hard to stuff in down there. The size diffrences are, the casing is another .75in larger and the intake side is 4" instead of the 3.75" on the d1sc.

I would like to know that as well.... I can't find flow and max impeller speed information on the F1-A. I hope Bob or Jake from EPP can give us that here. All i know is that is the F1-A flows 100 CFM more than an F1.

I asked Bob about that and he said the F1C has the same external size as a F1R.

i would think i would want the one that you dont have to spin as high to get the right CFM out of it or the one with the biggest step-up ratio so you can use a big pulley and not worry about slip....
or is it that you want one with a high impeller speed and a big step up?
hhmmm now im not sure i know....
what is this car going to be used for?

my buddy has an F1-C which is basically an F1-R with a less extreme step up ratio, afaik. let me tell u, the ride i had in that was nothing short of incredible. MUCH, much better than the D1SC, which is the same physical size as the F1

Usually when a blower have a high impeller speed they give it a high step up ratio so you can achieve that max impeller speed easily.
The car is a 02 Camaro with a forged 8.5 C/R 408 and AFR 225 heads.

For the F1 the step up is 5.4:1 and max impeller is 70k , the F1-R is 5.4:1 also but it has max rpm of 68k. The f1 has a max cfm of 1525 and the f1r has max cfm of 2000.

put it this way, 7" crank pully, 4.25" blower pully = 13.4psi @ 6200rpm on a 403 with ETP heads, ported ls6 intake and full 2" custom headers... thats an F1R.... it wasnt even spinning yet. if you want a setup that isnt being maxed, get the f1r

I want a F1R to fit and run 18-20lbs of boost, but if its going to be a hassle to fit in a F-body then i might just stick with a F1-A.
