Very nice! Sounds pretty rowdy!

It looked like you ended up @ 19 PSI - peak? I just wanted more, that F1A was just starting to come alive! Why not any more boost, is that a stock motor?

What cog pullies are you running?

I love cogged Prochargers!!!!

Its a built motor.


Thats all it made with the pulleys it came with. It has a 88 tooth crank and a 48 tooth blower pulley. I called procharger and they said I can go down to a 44 tooth for the blower. That would be the smallest pulley I can get without over spinning the blower.

I think if I was at sealevel it would make a lot more being at 6000 feet high just sucks.

Any headwork or cams in there?

Ouch, ya Colorado, I didnt see that. Thats gonna affect is in a big way

So a 88T & 48T with a 5.4 stepup ratio and 6800 RPM = 67,319 blower RPM. It looked like you pulled to 6800, and I assume thats a 5.4 stepup ratio F1A right? A 88T & 44T, 5.4 S/U, and 6800 RPM = 73,440 blower RPM

The F1A redline is 70,000 RPM per Procharger, but lots of guys overspin them by a few thousand RPMs.

Sorry for all the questions, I am putting together a similar project (different blower) and I am just trying to guesstimate what boost level I will see. Thanks

No head work at all. I do have sean hyland blower regrinds cams.

On my F1A it says max rpm is 74k. It is a 5.40 stepup

You can over spin a F series Procharger about 10K. It's done all the time. The blower is only at that RPM for a second or 2.

I'm going to do it with mine for sure. I spin my F1A to 69K now and see 23psi.

Mine seems to build boost quicker. But I may be spinning it a bit harder though.

The cog setup is sweet. I'm in the process of donig that to my 2V. I make 700 now at 6800RPM's but think I have another 100-150rwhp left in the blower. I have a shorty header on the car now that's holding me back from spinning the blower harder right now.

Sweet ride. I like the blower setup without the battery there. Makes more room for sure.
