Should I go with a F1C instead of F1A? What would the diff be between the both? Horsepower? Both around 14psi. Do you have to do anything diff to mount the F1C? I will be doing a LS7 427.

I'll have some numbers for you pretty soon (week or so). I don't have an F1A but on my setup in my sig I'm making 10psi on a 4" pulley, I have a 3.7" and a couple of other goodies. I'm hoping for another 4-5psi and high 700's.
I just need to figure out the belt I need for an 8 rib with the 3.7" pulley!

Only one place to buy the SDCE drive from..

Here is an ATI ProCharger F-1A on an LS2/402 with unported AFR 225 heads. LS2 intake, LS2 throttle body, Kooks 1-7/8 headers. 14.4 psi of boost for now, we'll up it down the road. This is on our Mustang Chassis Dyno, Dynojet numbers would be higher. Bob

I'm pretty sure if I didnt have an SDCE on my car it would have had a turbo on it a couple years ago. The LS F-body procharger bracket setup is not really made for big power drag racing, if you stay F1A or under the SDCE (or ATI 8-rib if you dont mind changing belts fairly often) will be fine, IMO its not enough for something like a F1R, it may do a F1C but I dont know, big difference between dyno and dragstrip as far as belt slip goes.

What pulley would you go with? Motor will be 9.5 comp.How accurate are the pulleys? I see they come in 14lbs or 16lbs pulley. So how did you get 14.4psi ? Also I think I read you recomended getting a k&n air filter for the kit instead of there filter. Is that true and why? BTW I will be running your FMIC kit on this set up

Also, when pulleying up these larger blowers, it does increase the strain on the belt. Like any car running more boost / high hp it is a wise decision to have a good tune-up , and depending on hp you will need racefuel.
The pulleys come in sizes not pounds lol.
We usualy put the biggest filter in there when we can, this is due to the ATI stocker not being big enough to flow proper inlet air.
The fact of reality is that the ATI Fbody kit was not designed for a high hp F1 blower, im betting it was not even designed for a cranked up d1sc.
The base kit is a p1 kit with 6rib, you can get a 8rib if you run more boost, but ati probally didnt expect people to be running this much hp on street cars.
The ATI bracket may not be enough for a daily driven street car, you will have to tension the belt more then it needs to battle belt slip. As KP said, the SDCE is the only option for this situation.
As far as pulleys go, we see max impeller speed at 7k with a 3.90, it turns about 18-20psi. As far as efficency, we used to see 130-150ish IAT's with our epp fmic setup. Now with a w2a those are below ambient. We still have to tighten the belt every run or boost will drop off.
Like anything else, when your trying to max a setup out, you will encounter big issues, look at some of the bigger ford classes running spec blowers having to tighten the belt like crazy, 1 belt a run gets pricey.

F1C/F1R I would certainly look into a cog if you were drag racing the car, but just slapping a couple cog pulleys on there and maxing out an F1R isnt that easy on one of these..

We have thought a few diff ways into doing so, but nothing has came of yet.
As for cogs, its almost useless to run a setup without getting into the 60mm range where you can get a kevlar backed belt. FYI 60mm is just about 2 x a 8rib belt wide.
A custom radiator would be a requirement and chopping the front support, defiantly not a retail kit, all custom race-car stuff.
Only other venu would be a gear drive unit from Supercharger-store, these run in the range of 3-4k, im betting non street able.

Aint that the truth

A custom bracket for a f2 would get it done for sure, anything over a small f1 will probably bend the ATI alum bracket anyways.
