Re: The ITB info thread.
the same holds true in all aplications, carb or ITB.. a longer runner will make more power on the top end while a shorter runner will make more low end power... bike TB's are rediculously oversized... you'd want it as short as possible for a honda. i run 40mm webbers on my celica's 2.4 and it breathes very well on top. ITB's flow way better than carbs

Re: The ITB info thread.
Flyspyder55: I think you got your info flipped there my man. Longer runners make more bottom end torque. It's like what happens when you add a throttle body spacer or a carb spacer to a Chevy V8 truck, you get more torque for towing. Short runners, (ie. ITB's) make more top end horsepower. Which is why motorcycles run carbs or ITB's right off the cylinder head.
