Roller / Barrel Throttle bodies

[Adrian Bravo]

I should probably post this in the cinq section but out of interest has anyone here used Roller / Barrel Throttle bodies

This is what they look like;

I find slide throttle bodies interesting just in the way they move. apparently they lack fine controll which is solved by roller/barrel TB's

This is a nice read

waste of time, ridiculously expensive and no better than butterfly bodies (dyno proven).

I would expect gains if any to be had at throttle wide open only, over standard butterfly ITB's.

I like to see different approaches. it is nice to see other design ideas and solutions.

Thanks rich. That is a big difference for such a small change.

What type of throttle bodie does your sedicivalvole use? I have to say I saw one of your cockpit view racing videos on youtube and really enjoyed it.
