Hi, Rusty...maybe I misread the TWM site, but I just clicked on the series 2900 throttlebody, and it says they are available in the following sizes:  40, 42, 45, 48, 50 and 55mm.   Maybe something new?  Paul Conner

It’s a TB made by TWM induction; http://www.twminduction.com/

 

BTW; Rusty, what diameter barrels on your TB?  Mine are 44 mm, which could be great for automotive street or racing), where idle transition and throttle response are more important.  For aircraft I do believe that a bit larger would be better. 

 

Hi Al,

 

I've measured mine a number of times, and I recall that they're essentially 1-5/8, which of course works out to about 41mm.  The TWM site only lists 40 and 42 for the 2900 series, so I'm not sure exactly which one I have.  I got it from Atkins originally, with the wrap over manifold, so I got whatever he was sending out.
