anyone here have a 85mm bbk throttle body?

What exactly does the spacer do and does it come with it?

It's separate, my understanding is there is interference issues, you can port the boss or run the spacer. I suspect it is with the vertical veins at the mouth of the boss and the TB blade itself but I have not got around to messing with it yet.

Sorry to paste from another forum, but here are some results N/A with the 90 mm t/b.

Good read thanks for the link. Looks about right with what I figured it would make on a heads / cams car.

Im curious about this debate about the IM opening.
You typically want the opening to be slightly larger than the TB (perhaps like 2mm larger), but never want the TB to be any larger than the opening in the IM.

I suspect that this spacer may be designed to create an ideal inlet requiring a larger throttle body. Unless of course it turns out that the Boss IM has a larger opening than we think.

EDIT:
So I looked up the part number for the spacer, and found this:

It appears that it may just have a taper to it, although its hard to tell from the photograph.

There are two spacers. one for stock gt and one for boss IM.
If i can get some calipers ill measure stock and boss IM openings.

It will be nice to get this issue settled once and for all. Please measure the cai outlet also.

ill get measurements of stock and JLT Carbon.

The stock and Boss inlet sizes are both 83mm.

Ford is claiming FFRP requires tuning. L and M doesn't and I don't think BBK does either.
