[QUOTE="Guy, post: 1141028, member: 22717"] I'm not much of a turbo guy so I won't dispute any fundamental truths in that regard. I hear what you're preaching and I want to buy in... but I'm not so sure without proof of concept. I'm going to make up variables to illustrate my point. Let's say the engine produces a flow and a pressure coming out of the combustion chamber. Let's say that flow is based on a resistance with (X) number of resistance at the turbo outlet as well as the rest of the exhaust system... for a given change in Pressure with a fixed resistance you'll generate a rate of flow. Flow = change in pressure over resistance. If you decrease the resistance you will decrease the flow rate but potentially move an equal volume of air or even a greater volume... What spools the turbo? The exhaust flowing through the turbine right? If the exhaust flows through with less velocity because you decreased the resistance... isn't the turbo going to spin slower? Someone who has had college level physics in the last 20 years, probably could explain this better. [/QUOTE]
