Back Pressure

[guysh]

I maybe wrong but I thought I asked Lee when I was at the factory one day about whether or not the engine & Turbo's require any back pressure and I thought he said that the less back pressure the better... Anyone know?

It makes sense on a turbo'ed engine, the only thing that spins the turbo is exhaust gas so the faster that is moving the better, back pressure for the purposes of creating standing waves to draw more mixture in to the combustion chamber is also irrelevant as the turbo is already forcing mixture in at high pressure.
