Is there such a thing as optimal back pressure? If so could it be mechanically controlled or would it require more than a spring and a flapper valve set to a PSI?
I'm just thinking about how to get both. Of course, I don't know **** about cars. I know tubes and valves and pressure and how gases move.A tune can get around it. The back pressure changes will change the MAF calibration.
Depends on what you are wanting. Low down power can be improved with more back pressure but then you high speed will get cut down. Or low back pressure will help the high speed and hurt the low end.[/b]
Essentially a waste gate used in turbo systems.I was thinking of just a simple spring loaded valve that opened the exhaust to an open pipe on the passenger side via a Y at the axle.[/b]
