I searched and found this info for DIY/Home porting your stock throttlebody, but the images didn't display inline.

So I fixed the page, cut out the crap, and converted it to a PDF file.

The info in the PDF is from High-Tech HorsePower - Porting Your Throttle Body by Buffhomer

 

good read except for the epoxy part. Lots of great info here on Tech as well.

 

nice work bro!
