Hi I recently got an ITR Manifold, my setup is on my sign the only difference is that now I'm going w/Skunk2 Pro Cams and 2.5" collector, I use my car for drag racing/daily drive, what do you guys think about porting & polish this manifold would this help me to get more high end power or it just could make lose some mid range torque?

 

It will help.

 

thanks

 

Rocket, by the way do you know where can I buy Online some gen2 RM valve springs?

polish?...hmm, i would not polish. port, if done within reason, sure...but don't polish, keep it relatively textured, like stock runner-interior texture.

 

I would think the smoother the better since you want as little friction as possible.

You dont really need turbulence until you try to mix fuel with it.(I believe)

I would say yes it will help also. Probably help your powerband in the upper regions.

 

Contact me via e-mail is best or a dealer.

It is difficult to port much more than middle to end of the runners of the intake manifold, unless you cut it like Endyn does to get into the plenum & runner entryways, then weld back together. I am assuming the thread starter is not intending on cutting and welding, so he is probably inquiring about treatment to the middle/end of the runners, since these areas are the easiest to reach for a DIY guy. It is the middle to end of the runner area that you want to start promoting fuel atomization and also, this area is one that i would not polish.

that is correct I'm not intended to cutting the IM, only porting & polishing (maybe) from the middle to the end my idea was in order to make the runners exactly match the same size and polish work as the intakes of the head (which is already p&p).

 

gl hope it comes out good

matching the runners to the port/gasket is a great idea, however...the ported head should not have the intake port polished as you mention. If it does, rough it up with some 500 grit and do not polish the runners from the middle on out....
