Hasselgren 4age billet barrel throttle
While looking for some ideas of what to use for throttles on the 3UZ-FE I came across the 'roller' type throttle body, i had never heard or seen these before so i thought id chuck them on here for every one to have a look at it.
More info and pics here:

very cool but I don't think they would be as responsive as a normal butterfly more mass to move when opening
Rust is a way of life
they are the oppisite of what you think actually alot rougher and produce more power..when driving they are closed or a bit open hard to explain but ive heard you would struggle to drive on the roads
only good if your either off it or flat chat gasing it
but unlike slide throttles the application is still linear
i would say they would have much better air flow as there not a butterfly in the middle disrupting and restricting air flow (air velosity?).
these would have a much more smoother and prisice power delivery.
these are just my own observations. so i could be completly wrong?
yes you are right about the first wrong about the second.
^^ mostly at WOT though - intermediate throttle positions would still have loses similar to a butterfly valve.
And I don't think the actuation would be linear unless you were running a well thought out cam in the linkage. Area would increase a large amount during low to medium throttle positions and level out toward WOT. One of the reasons why they're not really suited for road cars.

Who races down a straight at half throttle anyway? I could see how this wouldn't be too good for trailing throttle though, but I wouldn't say that it would be all that bad.
