F1-A or F1-R
E.A. glad to see you here-hopefully it will be lot more civil here toward the Prochargers than over at the CF forum. Okay-I'm getting a bit confused now. Your saying that the Procharger 8 rib upgrade has the blower crank pulley, blower pulley and tensioners. Your saying that the blower crank pulley bolts up to the ATI hub? What is the part # for the ATI hub with the ac pulley that is needed for this? Also what is the diameter of the crank pulley? Last I saw the ATI unit was only 7" in the 8 rib version-I don't understand why anyone would want to go smaller than that?

Corvettes: The Blower system runs on the same belt as all the accesories
F-Bodys: The Blower runs a dedicated drive. Just for the blower.
When you upgrade to the 8 rib system on the Corvettes.
You get new.....
spacers for the brackets,
new idlers,
p/s pulley,
alternator pulley,
blower pulley,
But you still have to get the 8 rib ATI Perf. Products Balancer from another vendor. Since ProCharger doesn't stock them. This is what is going to run the supercharger. It's the same diameter as stock, just wider.
Balancer Part Number #917345
When you upgrade to an 8 Rib for a F-body
Since they run a dedicated Drive that bolts to the balancer.
You get a new....
crank pulley, (7.65")
new idler,
spacers,
blower pulley.
But you will have to buy a 6 Rib ATI Perf. Products Balancer from another outside vendor, being as though once again, ProCharger doesn't stock them. The part has NO bearing on boost level, being as though it's not turning the supercharger. It is mearly a better mounting surface for the ProCharger crank pulley.
Balancer Part Number #917242
Yes, you have to buy a new balancer even though the Crank pulley is bolting to it. Reasons are simple as to why.......
1) Machined mounting surface
2) Stronger Hub in the balancer it's self.
3) High HP motors, should have this part on them anyways. your taking chances running the stock stuff.
Hope this helps,
EA
PS: You also have to get the ATI Perf Products Balancer Pinning Kit. Since it is different then the ProCharger Pinning kit. I believe, don't quote me on this, but I think the part number is PN# 918993

You can also use a restrictor on the inlet to keep the boost down. If there is less air to compress it wont heat up as quick as doing a wastegate type thing I wouldnt think.
when you say "yes"... you mean it wont be overkill on the street? like say it hits 90 degrees, in the summer, i'd need an a2w-instead of an a2a? is there any real big issues with driving that kind of power on regular trips?
I'd pick the blower that fits the stock brackets and let's you run a decent size filter. I think the guys looking at running custom size blowers are glossing over all the changes they need to make. And wait till you try making over 20psi, you'll need a strut brace.

You still need a race bypass. Street driving is not going to hurt the blower. I'm pretty sure there is a video on here of a Camaro with either the F1C or F1R street driving. I seem to remember a night shot or something. Maybe he can weigh in on his experiences with it.
