Where to buy throttle butterflies?

[Porschekid962]

Hey all, I am working on a custom intake design. It is almost finalized but I wanted to know where if you can, purchase brand new throttle butterflies in varying sizes. I am certain there are places to buy Weber and TWM and Jenvey but if I am looking for a size they dont carry where could I find it?

I found one decent place on the web that caters mostly to american cars, no biggie though. My big problem is rather vague descriptions, no technical details but the prices are great.

So if any of you know could you tell me?

At this point in the project I just want to get the prototype on a motor and sort out any issues before I go forward with the project.

Thanks.

hi -

try Kinsler - I did the same search and they were the only ones I found. Problem is (for mfi) their butterflies as built are cut for a 14 degree angle, and the hole spacing is different. Find a decent machine shop and they can make a jig to turn them for you for not a horrendous amount. I believe Supertec also makes or has made the butterflies for the MFI.

Please let us know what you end up with - btw is the application MFI or something else?
