someone told me if i unplugged the vacuume tube from the thing that holds the secondaries closed that it'd help me gain power because it'd be open all the time. i've already asked around and some people tell me i'd loose torque. im just looking for more opinions. i've already tried it and my engine does sound louder, but i cant feel any difference in acceleration. has anyone ever heard of anyone doing this? i wouldnt be doing this all the time, only when racing (if it even helps) i mainly do autoX.
thanks,
Jon

 

Intake runners reinforce the flow by reflecting sound waves off the entrance from the plenum. Longer runners for lower rpm, shorter runners for high rpm. You can imagine what it'd cost to make runners that work like trombone slides...

Leaving the long ones open at high rpm doesn't hurt, but leaving the short ones open at low rpm messes it all up.

 

so what your saying is, dont do it?

 

You'll lose low end power if you do this. If you want to do it right, get a skunk2 or some other single runner manifold.

 

exactly. the secondaries are there for a reason.

 

alright, thanks for all the info guys.
