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)

Okay,

Based on the input from some rather experienced and talented chaps here, I'm gonna stick with the plan of developing the IR throttle setup. Probably gonna use Megasquirt.

I'll be setting the car up first with the stock D-Jet, just so I can get the darn thing going. Once the car is on it's wheels again, I'll start the buildup of the MS hardware.

Thanks all!

I suspected the IR setup would be better, but not by much with a stock motor...
