Default RE: What size are throttle bodies?

thanks for finding that for me. I was thinking about ordering turbulators for each throttle body. They create a swirrled vortex to the incomming air which is soppesed to increase throttle responce and midrange. Similar to throttle body spacers on automobiles. Since I can get dealer cost, I wouldnt mind trying them since it wont cost me much. Anyone have any input?

If getting them at cost ,it cant hurt to try but dyno it to see if it actually helps..The butt meters really dont tell the story..

Throttle body spacers are a waste on most cars.Its more hype and BS than anything else..Been down that road and have many dynos to prove things like that dont work(at least on cars).
