Its pathetic when I was proven a point and someone literally erase's a complete thread. That's ok, I see this forum is one sided and if proven wrong they get rid of the post. Here is something I did for two days and not one machinist could actually test it them selves but claims he is a good one :-( I wouldn't take my stock junk to him. Sonny's top engine builder and Reher-Morrison's top engine builder, which both have literally 1000's + hours of dyno testing, not just running a customers engine to collect data but, testing hours. and they both told me this, "With 6 90 turns before the cam journal's, you'll never solve the burnt up, worn down, and spun main bearings problem. Volume is something taken very serious in our shop on oil supply because, over pressurized system will just blow oil out the bearing." Now, that's coming from the two top engine building establishments in the world. If you dont want to listen to them then, the problem lays within you or the engine builder! I know what I'm doing, listening to Professionals, not someone trying to make a name for them selves... the balance line should be used if using something to get rid of the 90 turns. So far the SCAVENGER SYSTEM IS THE CORRECT SYSTEM TO ELMINATE THAT PROBLEM PERIOD. Sincerely Gary M.
