Yes, porting does help.

How do you propose to control the throttle without the butterfly valve?

 

[farhan al mustaqim]

I don undestand, what is the purpose of butterfly valve for throttle

 

[pwhyze]

Well, the only butterfly valve I can think of in the intake system is the throttle body, no?

 

[farhan al mustaqim]

Yes, but for black top h22 , it has iab valve, in the intake manifold, but for euro r h22, it doesnt have it, do u own h22a motor?

 

[^pomen_GTR^]

more or less its like the variable intake manifold a.k.a iafm


u want to gain some u must be prepared to loose some

 

[pwhyze]

Ah I see..An IAB valve..thought you meant the TB

 

[farhan al mustaqim]

Wat is low end power? and, what about de fuel consumption if porting the intake manifold and remove the iab valve

 

[LOPI]

U will loose low end power but better gain for high end power...fuel consumption wont effect much...
Any reason u want to modify your dual runner intake manifold?

 

[farhan al mustaqim]

coz i heard do it like that wil increase de pawer, ... and, what is low end power? it is the power created at low rpm.?
