I am starting to play around with tuning and plan to start getting some small increments in jetting. Just to see if I can improve drivability for now. I have twin 44s
Simple question for now: I need 4 turns of idle mixture to now stumble off the line. Should I consider jetting richer? thanks |

I understand the consensus ( for overall sizing is 40mm max). In order to do the road tuning thing, I will need an O2 sensor even if I had 40mm. Budget and time limited for the time being. As for the technical feedback, Bernouli's equation defining air flow although a first principles estimation, is not invalidated because we are talking about a VW engine. I am only interested in tuning my car for track use. Yes, 6800 rpm is per tach(i know this is not entirely accurate). This is just a sizing calc point. And yes I threw off the alternator belt that was on the car when I bought it. Not having that problem since I put a new one on. eye candy.....
