Throttle body flange dimensions?
Can someone tell me the basic dimensions of the TB flange? I'm looking for the distance from one mounting hole to the next and the size of the bores in the body. And maybe a pic of the bottom and top of the TB would also help if anyone would be so kind. Thanks.

Thanks for the pics. I basically would need to know where to drill holes in a solid plate to mount the TB.
What's with the two sets of butterflies on the secondary side? I wish I just had a TB to look at.

the two sets are so the secondaries can be cut off outside of the primary throttle linkage. (for cold start)
I'm also interested in the equivalent size of the TB in a round single butterfly...

Do you need pics of the back side where it mounts to the dynamic chamber (4 holes)...?
I can take pics and get you all the measurements you need, this is the stock TB from an S4, I also have a modded S4 TB (port and polished) If you need pics of that.
There are some in depth pics at
Thanks Ted

One set of studs is two and thirteen sixteenths from center to center. The other set is three and three quarters from center to center. The center of the top set is four and one sixteenth , from the center of the bottom set.
