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.
Rusty
Are you guys talking about 2 barrels? Right now, I've got the choice of a 66mm throttle body that came off a BMW, or one of the 60mm Mustang bodies.
Two 44mm barrels comes out to about 3041mm^2.
The 60mm body would give me 2827mm^2
The 66mm body gives 3421mm^2
I'm leaning (well, basically decided) to go with the 66mm. Will I regret it?

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
