Sent Rotor Housing to Paul Lamar for P-Porting... Milled 2" hole and Welded SS Pipe in side of Housing to create the P-Port Exhust... The Next step is to contour Weld inside rotor housing and Pot the Tubs into the housing using Liquid Aluminum. Will also have to contour the Sealing block on outside of housing by using JB Weld.
