Got the butterflys in today and they bolt right in. This was the hardest part finding something to work as a bolt in.

I bought a set of new throttle bodies off the Brute Force just to see what they looked like,and to see how much the flow against the DASA 38's. What I didn't look at when I flowed the 38's is that these come with a taperd bore. I think I can bore these to the 38mm and then taper bore them to flow better.

Cost wise I think I can do the straight bore for $275,and if the taperbore flows more they will be around $350 depending on set up time. These prices will all be on a exchange basis.

Before I bore the 36mm Brute Force T/B's I wanted to flow them so we know what everything flows as of to day.
