I would think that with all the emission control devices on the exhaust, we already have all the back pressure we can handle....dmako said:Some engines require 'some' back pressure to operate at peak output.
Sadly, with a BSME I ought to know how backpressure affects engine performance, but I don't...EdMPT said:I guess if someone knows how back pressure affects engine performance then it may explain somewhat how this works/doesn't work...
Remove discs to decrease the exhaust opening and increase back pressure.
* This decreases the powerband to give you more low-end torque.
