Handbuilt 4-Rotor Engine

This was a project that took about five years of weekends to put together. There was a lot of trial and error as jury-rigged parts were improvised and revised, leaks were identified and plugged, and byzantine electrical diagrams were decoded. It still does not run smoothly, as there likely is a problem with the intake system that has prevented smooth timing at idle. But she runs!

Im an american car kinda guy but rotary engines are kinda cool.

@crazyjek762 most liked comment ^^^ i think so

[BruceLayR8]

what are the power figures for this engine

[DearAlbert1]

Kudos for the balls to do this! Where did you get a 4 rotor eccentric shaft? You better get at least a 3inch engine back exhaust, hook up your radiator to your engine(fill it with rad fluid too), put on an intake system (plumbing, Air filter/intake), dual oil coolers, stand alone engine management. If you don't do these things it will never be drivable. Keep up the project and get some professional (RX7 tuner shop) help!

thats amazing work, where can i find more info on it?

@speedjunkie13 it has an ending one to make the burn more efficiant therefore making for power, smoother and no petrol goes to waste, it all gets burnt (well most of it)

[stirunner95]

fuck exhuast just run a straight pipe hahah.



[rx7vtec]

would you not need a exhaust at least twice the size of stock?

[speedjunkie13]

To the fuel consumption comments, from what I understand the 787B 4-rotor (26B) had an extra set of spark plugs that helped burn more fuel mixture and somehow made it more fuel efficient. Don't ask me how, it's just what I read haha.

what a smooth revving engine :)

Rotary engines has only one drawback, fuel consumption, but the world havent really seen what theyre good for yet - on hydrogen, they will outperform any other IC engine....except maybe a turbine - and hydrogen being easy to make for free, the consumption doesnt matter anymore. also in an airplane f.ex. the lower weight evens out the consumption,, and you get the same range as a heavier, less thirsty motor. Its only buisness why they are not everywhere in cars yet...
