F1 on a street car?
F1 on a street car? I have an opportunity to purchase a complete Procharger F1 Kit for a good price. I was just wondering if any one was running them on their street cars. Questions. Will it fit under the hood of my WS6? Will I loose any of my accessories? Can I run the boost low enough so the stock short block can handle it untill I can get a forged 408? How street able is it? The final goal is 800+ to the wheels with a 408 and AFR 225 heads. I don't mind sitting on for a while until I can't use it on my stock motor. This is probably a dumb question but, can you use a Waste gate on a blower like you do on a turbo? It would seem to me that you could just run a smaller pulley make boost faster and bleed it of with waste gate. Maby not. Any help would be appreciated.

There is no need for a wastegate on a supercharger, a wastegate is a valve that opens when the manifold pressure reaches maximum boost levels to vent off exhaust gas and prevent a turbo from making more boost.
What you need for a supercharger is a different pully to adjust the boost level, you should be able to make as little boost as you want, you can also get a blowoff valve which relieves pressure on the s/c and intake pipes when the throttle blade is closed, but that isn't really a boost control device either.

superchargers boost levels are dependent on rpm, the only way to keep the psi down is not to rev it so high. The F1 will probably make a lot more than 8 lbs on a 346 at 6000 rpm. You can try changing the pulley on it, but I still think that sucker is gonna blow a lot of air cause of the impeller size. You can try it but I'd have emergency funds for a new bottom end since the ringlands are the weak link. I wouldn't risk it. As far as 800 to the wheels with a 408 and afr 225's it should do it no problem.

Thanks for the info guys. I have been out of town so I havn't been able to respond. I am getting the kit from a forum member if all works out. It is a GMMG kit set up for 5.5-6lbs with brackets that will fit it under my hood. The only think I need to provide is injectors and fuel pump. All parts are in the wrapper with a polished head unit for five grand. Sounds like a good price and investment to me.
The kit hasn't been used. All the parts are still in plastic. I have looked at Tbyrne and it seems that they want 5,500 for a non polished D1 kit. I would assume the polished F1 would be more. I may be wrong though.

you need to run a blow off valve with a supercharger, the kit should come with it, the valve works when the throttle shuts, the valve opens to relese the excess psi, so you dont surge the impeller, which can cause the bearing to fail. since its a f-1 its the same size as a p1sc or a d1sc just a bit thicker body. the f blowers are mean even with a big pully,
I was kind of wanting to do this in stages. The blower then some 72cc AFR 225's, then the 402 short block. How much boost will the stock short block stand up to? I am figureing with stock heads 7lbs at most. Then with the AFR heads and around 9.0:1 comp maby 12lbs or so. I would figure I can get about 600rwhp out of the stock 346 with heads and cam. Then really crank it up with the forged block. Won't a larger cam bleed off boost as well? Say somthing in the 230-240 range. Thanks for the imput guys. You are helping me out.

with a conservative tune, the motor will handle alot more than 7 lbs, but you will have to have address the fuel side of things. Bigger injectors are a must as well as a tuner to adjust the fuel and timing.
You should be able to make the type of power you want with no problem.
A larger cam will not necessarily bleed off pressure ... this is controlled more by the lobe separation and overlap than the actual duration ... even though usually larger duration figures will tend to increase overlap, this is not always the case if the cam is designed for forced induction ...
Does anyone know if the F1 will fit with a stock Rad and AC condensor? That pic in the above post looked like a custom radiator and shroud. It even looked like they angled the tanks of the rad to fit up tighter to the tie-bar. Probably means there is no AC. Space is pretty tight there. Just something else to think about.

I guess it is a low mount blower. I am not sure. The guy I might get it from said it is a GMMG kit with a different bracket to make it fit under the hood with all accessories. This will be a daily driven pump gas car. I couldn't stand to do it any other way.
