Ported my 2013 Throttle Body Today. Lots of PICS>>!!
The snow is flying outside. And inside the aluminum chips were flying..!! I decided to port my 2013 RAM TB today. I have done my fair share of cylinder heads and intakes over the years. So it's nothing new to me. It was a breeze. I'm pretty skeptical of ported throttle bodies. But hey. It's just time for me. I didn't have to blow $400 for the exact same results. If there are even any results to be had other than it looking real nice...
So as it stands I built my exhaust system Friday night and installed it. Installed my Trinity tuner Saturday. Ordered my Hemifever tune Saturday afternoon. And ported my TB today(Sunday). I'm on a roll..!!! Haha
Bad thing is it's full on winter here now and be damned if I'll be able to let my butt dyno tell me F all.... It's just Spin spin spin. The joys of a slammed 2wd truck in the winter...
I've done a lot of porting. So I have all the good tools. It's all with air die grinders, carbide burrs, cartridge rolls, and port polishing cross buffs.
As for polishing not entirely but the cross buffs make it smooth as butter. Polishing is a term thrown around too much and people relate it to a must do for maximum power. When that's not the case at all. It's not a requirement. In a TB it won't hurt anything nor will it gain anything. In cylinder heads/intakes it will be a negative affect. Smooth smooth polished ports and bowls are bad bad.
there is something I don't quite understand about ported throttle bodies. if it bottlenecks down to the size of the stock butterfly what is the point of the outside edges being bigger? that's prolly a stupid question but its something that ive wondered about for awhile

It's a venturi effect. When a bore tapers from big to small and gradually back to big it speeds up velocity. It's a good thing Of course there's all kinds of technical jargon that goes with it that pertain to pressure and velocity. But that's the easiest way to explain it. Just Google "Venturi Effect" if you wanna read up on it all.
