hey guys, i'm picking up a skunk2 intake mani for my gs-r motor tonight, and i have a few questions. Will both my primaries and secondaries hit at 4600, or are my butterflies totally elimnated now? I'm not exactly sure if this is better or worse for the motor. And what are some other bolt ons that will compliment the manifold well. Sorry for all the n00b like questions.

Ryan

TIA

 

base on my experience, i think i did loss power off the line and a little midrange...but gain more on top end...this is just basic bolt on without any ecu or anthing..i think if u get some ecu like a p28, u can benefit more

 

The butterfly system is eliminated on the skunk2 manifold. The advantage being you have more top-end power. The disadvantage is you lose a little low and midrange, like smkngsr said.

 

The ports dont even line up correctly. For optimum performance, the manifold needs to be reworked.
