What do you guys think is the most boost i will be able to get out of an F-1A Blower??


396ci around 9.2:1 compression
AFR 227 fully comp ported heads
Big solid roller prob spin to 7200-7400rpm
Single plane manifold
FMIC with 3, 3.5, or 4'' piping

 

I'm runing 18psi the system is capable of running 35psi but thats the max, I would think 30 to be safe and manageable. What are you trying to do?

 

Trying to make 750 rwhp on pump gas.....shooting for 800 but would be happy with 750 then add a meth kit

 

What engine? I built a 383 LT1, 18psi F1 ProCharger and the engine made 1043hp. I'm having problems with transmission now, I can't find anything to hold it. Once I do, I will bump up the boost to take out the power loss though drive train. My goal is 1000-1025 to rear wheels. Pump gas and no meth inj.!

 

Wow!!! Ya thats my ultimate goal about 850rwhp=~1000 flywheel hp

What are your rough cam specs??

 

On my 383 with fair but not fantastic heads the max boost out of the F1 is 26psi.

26#s huh NIIIIICE!!!....are you running ARP studs and fel-pro gaskets. J/W cause thats what I was planning but I'm hoping I dont have problems with the studs leaking coolant.

 

26# is nice, how much hp are you putting down to the ground? As far as coolent leaking when torquing the bolts go up in increments not to spec lbs, this will help spread the weight/pressure over the gasket.

Thats how I've been doing it and never had any leak other than water pump blowing and thermostat giving out. If your not runing the car in winter and your not leaving it outside try a leaner mix of coolent. Coolent does eat those gaskets too if the engine does not run for a while.
