Paul I was surfing the net looking for some Renesis intake and exhaust
data. I found these pictures and video posted on Nopistons.com. I saw
some of your info on some posts - the authors did reference your web
site. I could not determine where these photos originated.

Looks like the Mazdaspeed early slide throttle for the 13B
mechanical fuel injection for the 300 HP p-port road race engine.

Driving the slide like this seems like a more robust method than with a
threaded insert.

The load is not applied to the center of the slide so the slide
tends to tilt in the housing tending to jam. That is why I choose
to apply the control loads to the center of the slide.

Historicaly slide jamming has been the largest problem
with slide throttles.
