Where are the slide throttles from? Where'd you get them? Details! https://www.nopistons.com/forums/pub...IR#>/smile.png

You mentioned in the other thread that the slides were ineficient, have you tested them both?

I was bustin adams chops!, he wanted to see pics

You know how banzai is, whatever is already assembled is automatically more efficient... https://www.nopistons.com/forums/pub...DIR#>/wink.png



I really like those, I'm curious where they came from





In theory it's easy to make your own, but the devil is always in the details..

The problem I forsee with making your own is quick throttle response. Normal blade throttles will open and close almost instantly without a heavy return spring because there is almost no friction. With the slide throttle stuff I posted, its from an aviation source (www.rotaryeng.net), where throttle response isnt an issue.



And banzai, those things are sexy. But I didnt see you mention what they were originally off... https://www.nopistons.com/forums/pub...DIR#>/wink.png

BELIEVE ME!!! Throttle response will not be a problem!!!! These things are smooth. The reason I busted on adam is the drawing doesnt show the bearings!



These came from a person who was connected to the Mazda Racing Program in the 80's. MAZDA MOTORSPORTS (Brian/Scott) have heard of their existance, but know none of the details. I am searching for more info

Thanks Adam!

Banzai, you OWN a piece of rotary history!

OK well now its time to repro them things and sell me a set!!

Banzai is old enough to be a piece of history.

i have the breakdown of the 3 rotor slide throttle, but not the 2 rotor stuff.



lots of needle bearings in there, zr03-13-r21!



the whole assembly part number was zr03-13-r10

Can I get a copy please?

its in a buch, i'll try

Bearings make it much less scary.



Heres a vid from "Scoot". Itsa 4 rotor with slides on it.

Scoot 4 rotor

I want a copy too if you can

Why not post the info, Mike?





I stickied this for a reason.. https://www.nopistons.com/forums/pub...IR#>/smile.png

i'm happy to post it, but its in a book with glossy papre, so it might be tricky

Very Nice pieces....

I cant tell from the pics, but is the top air horn side of the throttleplate tapered?...The only one I have seen was tapered on the top side...

But yeah that is bit of rotary history, I have alot of pics of that setup on a 13b with bosch mech injection...

Great find, score of a lifetime...Maxt

Does anyone have a explode view or technical drawing of the inner workings ?



Thanks https://www.nopistons.com/forums/pub...IR#>/smile.png

I do https://www.nopistons.com/forums/pub...1047683664.gif

https://www.nopistons.com/forums/pub...DIR#>/wink.png how about sharing, banzaitoyota ?

Yeah, how about sharing those? I need to make a couple for two 13G (short 20b) cars.

It will be awhile, I have too many other projects right now that HAVE to get accomplished.

What's the advantage of slides over butterflies?



Mark

there is no obstruction for the air flow

Hey that's right!



Mark

So where is that exploded or technical drawing ?? mm.....

That's only true at full throttle. At any other throttle level they are a disadvantage compared to butterfly systems. When you consider that a race car is at full throttle most of the time, it makes alot of sense to use them.

couldnt u just make the butterfly throttle bodies a little bigger to compensate for the obstruction, or is that running into problems in terms of technical rules for the race series?

merry xmas

Great, early christmas present.



You mind taking a picture of the next page as well https://www.nopistons.com/forums/pub...#>/biggrin.png

sure, its a mazda parts book though, buch of neat parts you cant buy.

Mazda parts book ? mm....where do you get it from ?

you dont, its an old mazdaspeed catalog from 97? ive got a 2000 one too, but it doesnt have anything cool in it

Well I checked some of the parts prices on my account and damn they are expensive. The full thing is like $6600 US.

****... $ 6600 that is some clunk of change. Anyone do some reverse engineering to get some out for the rotary ?

Reverse Engineering isnt cheap either. As it has been said before: Show me the $$$$$, the majority of people when asked to pony up the $$$$ before/after a product is developed magically disapear!
