supercharger and tri-power

[64falconsix]

I have been contemplating my next move on the tri- power and after much debate i am thinking of going with a supercharger. if i do I will fab all of the hardware and inlet piping myself.what kind of increase could one expect with 5 to 6 pounds of boost?? on a 200 cube engine.

I just found a web site with a supercharger boost / hp calculator. the input i gave shows a 57 to 70 H.P. increase from 5 to 6 pounds of boost. I will have to do some more research as i know very little about superchargeing so any advice would be appreiciated.

8) when trying to figure how much power you will make with a super, or turbocharger, you can follow this rule of thumb. 15psi(ok 14.7 to be exact) boost pressure will double the horsepower output of any engine. cut that in half to 7.5psi and you pick up 50% horsepower gain. 5 psi would be like 33%. remember this is based on what power the engine is making now, so if your engine was making 100hp normally aspirated, then with 15psi boost, it would make 200hp, 7.5psi boost 150hp, 5psi boost 133hp. again these are rough numbers to give you an idea of what to expect when installing forced induction.

Not to rain on the parade, but I would ditch the tri-power when you go forced air. The complexity of the set up would be a nightmare. Plust, one of the advantages (proved in reality by Wills turbo falcon) of force air is you won't gain much by having the 3 carbs as far as power goes.

Just my 2 cents.

But, it would look awesome, I'll give you that!

thanks for the input. I have decided to go with the aluminum head when i build the supercharged engine

I agree with ditching the multiple carbs due to complexity, but I'm wondering if there would be any benefit to continuing to use the outboard runners? What I mean is to have the SC boost a sidedraft carb which then feeds a pipe/manifold (think of it as a backwards header) feeding the three holes where the tripower was.

8) that will work nicely as it will help equalize the boost pressure that each cylinder sees, as well as equalizing the air/fuel mixture each cylinder sees. just make sure that the three runners are equal length, and as close to equal shape as possible.

Something like that Hudson intake manifold on the other thread:
