Thread: Street scoop as throttle body?

Tweet

For building DIY EFI, do ya'll think a street scoop (Mr. Gasket type with three butterflies) would work as a throttle body?

I realize would have to get TPS set up on it, along with return spring. This would be for a fuel injected dual quad tunnel ram set up for a 454 BBC. Sorta' a larger version of Holly's Stealth Ram.

Or maybe I can work up some kind of rectangular plenum with a GM style TB on the front? I guess what I'm trying to build is my own version of an Accel Super Ram, for BBC, for under $1000.

Another way I could go would be dual 4v throttle bodies and a square air intake above them. Accel Super Ram

you still need a throttle body (or bodies, depending on your path) Bt really, buy a kit. You will save a ton of money and headache over cobbling pieces together from other FI units. Even when you get the thing together you will still have to have an ECU burned for your specific appplication- especially if its one off. If you really want to try to build FI from scratch make a mechanical injection, or a direct injection system. I suspect you will have better luck, although its still wont be easy. My suggestion would be to start with some tall air horns build butterflies, and a linkage system, get your injectors, and viola! of course it wont be that easy....

Was planning on putting together mega squirt ECU setup for this. After that, sky's the limit. Have found aftermarket GM or FAST style throttle body, that goes on the front of an air plenum. May use one of those, with a custom plenum. Just plumb the injectors into the tunnel ram, below the plenum, similar to a nitrous setup on a blower. That would be cool.

Want to do the same thing.

The buterfly's don't seal wel enough .
and are way to big for any street aplication.

I must make a new front part with a little smaler buterfly's and only use two of them
the mid one wil open but is closed of at the rear.
Look at the MS site to calculate the TB
diameter that you need.
