I've got a 5-3/4 Bottom and 5-3/8 top producing 5 pds boost on a 498 CI. I start boost @ about 3500 ++ RPM and it seems to peak @ 5 Pds. Through 5500. Engine is capable of 7000 but I want max RPM to be 6000-6500.I want 8-10 Pds.
Who should I ask for? I'll call you to discuss size and boost. Thanks. Greg
