Sorry, you have a misunderstanding of how an internal combustion engine works if you believe that.


The problem is, if you ram more air/fuel into the combustion chamber without an improved process to exhaust the spent mixture out of the chamber, you reach a point where the engine can't "exhale" fast enough in order to "inhale" more air/fuel faster or in greater quantities.

The point of an efficiently designed exhaust system is to create a scavenging effecct that helps draw the exhaust gases out of the combustion chamber when the exhaust valves open.

The design of an exhaust system absolutely affects how much horsepower and torque the engine creates at the flywheel.




I was under the impression that the exhaust gases were pushed out of the combustion chamber by the piston in the up-stroke . Not sucked out via a scavenging effect by the exhaust pipes and the mufflers.

I'm curious : If you were to add a supercharger to your Tubi equipped car, would you also have to add a SUPERTUBI exhaust sytem ? Or would your regular Tubis be OK to "scavenge" out all those additional combustion gases ? Lol
