BTW, 1.5 and 1.25 = is probably just what I would go to if I do a 4 pipe system, = which is what I'm leaning toward.

 

That’s a flow area of about = 3 sq. in./rotor.  About 25% more than my 44 mm barrels; and 50% more than = your 40 mm.

 

I’d agree; Rusty, 40 mm = barrels for 7000 rpm is restrictive.

 

Maybe I’ll rework my = induction system and $2000 intake manifold for a bigger throttle body (In another lifetime!!)
