Also that was with Flame arrestor? mine is gutted so I cannot see it being too restrictive..

All that was with giants air volute/bell on to keep headers heat out of intake, it poses no restriction, your fa looks like it poses no restriction either but i will test it too.

So can I send my QF's for norm to modify? Lol

He still does carbs and after testing his 4150 against 3 other carbs i am starting to believe hes pretty dam good. He saw immediate things with tims QF that he didnt like, example, secondary butterflys are not straight up and down when you hold it at wot and look thru it, he says who ever chose the booster design didnt knowmuch about fuel signal and curve but keep in mind hes a carb guy and a perfectionist at that. I have nothing to do with his carburetor business and am not even going to run carbs on my boat but heres a link to the guy if you want to talk to him or send him a carb to be evaluated etc :

Keep in mind, hes not cheap but damn good, Smitty
