For h22a ngine, Click to expand... Yes, porting does help. How do you propose to control the throttle without the butterfly valve? Last edited: Nov 19, 2013

pwhyze 500 RPM Senior Member Mar 1, 2011 924 356 1,563 Kuala Lumpur Nov 19, 2013 #4 Well, the only butterfly valve I can think of in the intake system is the throttle body, no?
