SOT: Homebrew ITBer's, whats the OD of the GSXR Throttle bod

[beast02er]

Hey, i'm looking to find the Outer diameter of the GSXR throttle bodies, the ones people are using for their Homemade ITB set ups. I'm looking for as close a value as possible. Oh, and i'm looking for the OD of intake side (the side that mounts to the head/manifold)

Thanks much,

Bryan

Anyone have a pic of that setup.. . interested as well...

Just do a search, a couple of people have made them on the board.

I'm just looking for the OD so I can possibly make a bracket to mate them to DCOE manifolds.

Does this help?

No, i'm looking for the dimension of the outside of the entire throttle body itself, not the butterflies or the inner bore diameter.

I guess they made us take drawing class for a reason in my engineering degree, cause in a case like this, a picture just works better! Hopefully the one I drew explains what I want.

I have 1.75" silicone tubing connecting my GSXR-600 TB's to my manifold. I think the GSXR 750 and 1000's will be bigger.
