Bored Throttle Body with working Balance port

One of my more challenging projects was to bore a Crossfire TB to 2" and 2.125" while retaining the ability to properly balance them.

First picture is completed 2" bored prototype puling 6" water on manometer:
Second picture is first prototype in progress. Note balance hole:

Looks good. If you don't mind me asking, what did you use to clean the outside of that unit, it has a nice looking finish on it.

If you mean the top picture, then those are chrome powder coated.

The bottom picture is carb cleaner followed by light abrasive blast in prep for powder.
