What is the maximum size procharger anyone has run on the aster bracket setup? I have heard of some running the f1a, and Bob at brutespeed mentioned even up to an F2 will fit. Has anyone run one of these blowers larger than the F1a on this bracket setup? The f1a-94 has a 9" volute and F1c/F1r are 9.75", F2 is 10.5" and F1x can be 10.5 or 12".

At some point I am sure belt slip with the 8 rib will again become an issue, but at what size/level? The CBR 8.6" pulley with a 4.5" blower pulley and his bracket still great belt wrap, so wondering what the max will be?

And it seems you have to move the radiator forward a bit and make a new intake for anything larger than an f1a, I am fine with all that just want to know if anyone has experience with f1x or f2 on the aster bracket setup?

I haven't heard of anyone doing an F-1X with the Aster bracket yet, but the F-1X takes less power to drive it than an F-1R does. The F-1X has a 10.5" volute diameter.
The F-1X-12 has a 12.0" volute diameter and it won't fit in the bracket. Bob

Thats good to know, so any 10.5" volute blower will fit on this bracket. I wonder if anyone has bolted up an f1c-10.5, f1x-10.5, or f2? With the new larger CBR crank pulley, seems a 4.5" blower pulley is necessary to not exceed max rpm.
Also if the f1x takes less power to turn, shouldn't have any issues with belt slip?

I wouldn't expect any belt slippage with an F-1X, I would with an F-2 though. The F-2 takes a lot more power to turn it. Bob

So you think the 8-rib Aster bracket could drive the F-1X decently? Wonder if anyone has done this yet?

Yes I do, the F-1X has a low parasitic loss percentage. I know I've sold at least one of these combinations, I haven't heard anything back yet. Thanks. Bob

I think if you get a 8.6 crank like i have it will help out a ton . letting you have that large procharger pulley .

I talked to a gentleman about an F1x Aster setup he was selling a few months ago. He was running the CBR crank pulley and seeing 32psi on a 370 with minimal slip on only a few runs that were data logged from what I remember
