Throttle bodies are on the way back from Maxbore.

He said it was crazy to work on. He did mine and TrippinBimmer's for $120 each, but said he would have to charge $175 in the future due to the complexity.

Stock butterfly was 67.5mm. Maxbore butterfly is 72.1. If my freshman geometry from 11 years ago serves me correctly, that about a 14% increase in area. Dinan claims 9%.

When I get them back I'll take the calipers and measure the inlet and outlet. Originally, there was a contour to the shape of the TB (hourglass).

For $120 plus dyno, I think it'll be a good experiment. (Especially considering what Dinan charges for them.)
