Supercharger and ITB's
J666AYP - 14/11/17 at 10:19 PM

Hi all,

I'm trying to get my head round the inlet for my project. I can either use the standard type of inlet with a plenum and single large throttle body or try to use individual throttle bodies in a sealed plenum chamber.

The car will be run on aftermarket management like emerald or omex, the question is will it/could it work?

TIA

Jay

I did a fair bit of reading about this subject ages ago as I have a long term plan (and a pile of parts) to SC my 4AGE.

The general consensus is to use 1 butterfly at the front of the plenum IIRC.

As my 4AGE already has quad throttle bodies, I will be sticking with them.

You can do either. ITBs work really well, mine made 400BHP on a Rotrex.

Cheers gents, as usual google has done me no favours lol.

Either works just fine.... I have done both

I've turbocharged my R1 engine and I've gone for a single TB combined plenum and inlet on the advice of my mapper as he said ITB''s won't gain you any power on a charged engine and take a bit more time to set up/balance etc.

ITBs will be 'crisper' to drive than a single TB but, all things being equal, not make any more peak power. I'd fit ITBs every time

Single tb will be smoother and more drivable as it will have a smaller cross sectional area.

I have itb's on my setup (gsxr), works very nicely
