I did grind a bowl larger than the seat on the prp side but it was a epic failure. as in Screeching Loud! port Lost 20 cfm and my Velocity probe said that the air was coming back up the port on the ssr prp wall. Filled it back in and problem when away. once again it look real good....but NO!
You dont want to get wild on that side of turn and wall. Just to get more cross section, but even then you have to balance it..or itll take over and half the port is torn from the straight wall right from the entrance. It gets all fkd up.
