Guillotines
Has any body fitted guillotines instead of the regular butterfly-throttle bodies? They are supposed to be better at full throttle as they can't cause any turbulence on the air, but they are also more difficult to build.

I can't find a good picture of at at Beninca site. Anyway, I'm interested in a possible fitting on a V6, anybody has done it before? We have been thinking about doing so and have built some wood stuff to take measures, but I'd like to ask someone who has already done it and see some pics.

As i understand it they are absolutely crap for anything but full throttle. They are also difficult to design since you will have a huge problem with the engine vacuum acting on the plate and making them stick...

You realize you need a return spring from the depths of hell to make it work?sh0rtlife wrote:a set of nylon slides on top and bottom would cure any stickyness..but i cant see getting a good seal out of it

This type of throttle has been around for a long time. they used to use small roller bearings to prevent engine vacum from jamming the slide but they were still vulnerable to dirt and normal intake tract buildup. On the other hand lots of motorcycle racing carbs have flat slides and do just fine. Also, why would you locate the throttle in the high velocity section of the port? Why not move it further away from the valve when the port widens up and velocitys are lower?
