IR vs. Plenum?, Bonafide dyno tests anyone? Options

[jhadler]

Hey all,

I realise that this may have been hammered at before, but I was currious if, on a stock 2.0L, there was any distinct advantage of going to IR throttles over the stock plenum (or some other single throttle plenum).

I know that the stock cam will limit the amount of air the engine can ingest, and that IR throttles will definitely NOT be the limiting factor on the top end, but with tall manifolds, and IR throttles, can a stock 2.0L run better than it could with the stock intake plenum. Assuming that both are running a programable fuel injection system that has been optimized.

Thought? Experiences? Test data? Dyno results? (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Yup, stock internals, but everything else (short of turbo-charging) is unrestricted. Kindof the opposite of production cars...

Already have the headers, and the stub pipes have already been matched to the heads.

So yeah, I'd be going with a programable FI system either way. I have hardware at my disposal for IR throttles, I also have a complete D-jet intake setup. The questions is, is it worth it at all to even try IR throttles or just stick with the D-Jet plennum?
