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.

This is beautiful work a long time before I built my throttle bodies
that I was completely unaware of  until today.  Apparently whoever
did this work  had both throttle bodies and slide throttles.  I
assume these units are not available today, but maybe there is a box
full of these parts on a shelf someplace,  I wonder if anyone has
info on how these units performance compared.  Is Mazda Speed still
around?  I will google it today.  Jerry


Well I uploaded pictures on here of the Le Mans four rotor many times
Jerry. Pictures are also on the http://www.rotaryeng.net site
for the last 6 years. Slide throttles date back almost 100 years
on racing cars. MazdaSpeed is still in biz but I'll bet they are
not cheap if they still have them.
