Flying toilet

anyone here have experience with them?

they are primarily used on V8's or other big motors. but the CFM they use is similar to 4 barrel throttle bodies used on rotary drag cars.

heres a link if you never heard of them.

http://www.killerrons.com/toilets.cfm

i found a few used for much much cheaper. i guess the re-sale on these isnt so great. but they are crazy exspensive new. but thats also for a whole kit. i would not use there wierd style of fuel injection. i would tap and weld 4 injector bungs on and get my fuel supply that way.

but i dont know if they use a TPS or not. i didnt see anything about it. i think they run off the injection kit tuned by jets and the pump. kinda like a carb but not on vacuum. but if anyone has used these "flying toilets" and converted them to be used with a TPS, let me know how.

thanks.

I have used a flying toilet before albeit not on a rotary. And before you weld bungs and start boring holes in it you might want to give it a try, mechanical fuel injection is not weird in the slightest it will surprise you especially if you have never driven a car like it before. They do not have electronics of any sort, the entire process is mechanical and is incredibly fast, there is no lag between your foot and the response of the car.

sounds good. but i would need to use a 1st gen style distributor/ignition though, right?

and the mechanical injection would'nt work with forced induction?

In the summers, I work for a mech. fuel injection company sort of similar to what you're asking about. The shop specifically deals with mechanical injection for small block sprint car motors. Mechanical injection is the norm on open wheel dirt cars. It is not uncommon for a 410cid built motor to make well over 800 crank hp on mechanically injected methanol system.
The real downfall to a mechanical injection system is tuning. Changing jets and calibrating the high/low valve can be a pain and is best done on a dyno. I would also imagine that you'd have to buy your jets from the manufacturer which can also be expensive. Imho, carburation and fuel injection have a lot more support and experience in the rotary community.

Mech injection does not care what kind of distributor you use it has no control over spark. They also have been used in the past for forced induction setups but they take quite a bit of tuning to get them to run right in that application.
