Since I'm in the process of rebuiling my 2.0 engine, I was wondering why 914 high performance engines use 44 IDF carbs instead if 48 IDF's or IDA's. I'm not trying to build a race car or anything to much but want to upgrade my 40 IDF's.

QUOTE How exactly does one overcarb an engine? the question should be "how does one NOT overcarb an engine" (IMG:style_emoticons/default/smile.gif) over carbing is basically having the port so open that you will run way rich, and just sloppy. a 2.0 doesn't need more than a properly jetted 40. properly jetted you will have smooth acceleration through the power-band. I suggest reading the tech articles on aircooled.net. they will really open your eyes (IMG:style_emoticons/default/smile.gif) QUOTE Too much gas+too much air=overcarbed engine.More gas and air do not equal more power. agree... in fact too much will BOG down the engine |
