How to port the throttle body
Porting the TB consists of removing the "ridge" that is in the mouth and polishing the surfaces. We have a few sponsors that will port you TB for you for less than $150.
A couple 60 grit sanding drums and a corded drill and you can sand down the ridge and blend it. Just don't sand by where the blade closes. Use a 150 drum to clean it up.
I also hand sanded with some 220 and then used my dremel and metal polish to make it smooth. Good for another .2 RWHP <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Shoot some brake or carb cleaner through it to get all the gunk off when you are done. Wipe clean and reassemble.
