what ecu? carbs and distributer. done

 

i didnt see anything of what theyre trying to achieve...but i do want to see is this thing redline. i want to see if the e-shaft can really can handle it

Zoom is quicker on the trigger.

 

It's over a year old thread ....
But FWIW I thought I would post a link to it ..

It wouldn't be that hard to find an ecu to run it if they build it much like a flat plane crank V8. In those engines they essentially have two 4 cylinder engines running a the same time since 2 pistons fire at the same time. This is why Ferrari V8's sound so neat. If they did this engine the same way by always having 2 rotors fire at the same time it wouldn't be any different than running a 3 rotor except that the ecu is firing and fueling 2 rotors at a time. It doesn't know that though. Not a very big problem to overcome. If they build the eccentric shaft where each rotor fires independently of another one then they are going to need at least 2 ecu's and a few bottles of aspirin.

My biggest concern for this is cooling. It is going to take several loop lines to evenly flow coolant and even then it will need a special separate water pump to do it. It will have to go dry sump to get the capacity and a larger radiator and oil cooler setup also need to be fit in. The exhaust will definitely be a nightmare but if they do the crank the way I propose they should then it would be nothing more than a dual exhaust with 2 headers that never collect with each other. Again, simple. Intake is open for interpretation and doesn't have to be complicated. Due to the length I personally wouldn't use just one throttle body and plenum.

There is a lot to work out with this whole setup. Fitting it in the car may be the easy part.

 

Truth

 

multiple electric water pumps, no problem

 

 

That thing better run 2's when it's done!

 

Right?! Imagine the 'braps' that will ensue.

 

thanks RotaryTherapy now i have to clean my keybaord bro...

 

Most wonder if it can be done - Kiwis just do it .......

 

Dear Santa,...

 

good god!

I like how it's not just a total pipe dream....of course the rest of the engine fittings have to be worked out, but there it is, sitting in a real car with tires and suspension! Can't wait to see where this thread goes....

 

That is bad ***... just to see someone do what hasn't been done before. It will sound like armageddon when it idles too, because it will be running like two simultaneous 3-rotor motors.

 

What about Tension Bolt Lengths!!

Another WOW!!!!!!!!!!!!

 

I can tell you with 100% certainty that if only longer tension bolts are going to be used to hold the engine together that it will not work regardless of the bolt or stud type used. This engine absolutely needs to have a complete structural cage of some kind built around it or it WILL come apart.

 

^ As much as I'd like to see the engine in person, I don't think I'd care to be anywhere near it if that happens.

 

just a tad ummmmmmmmmmmmmm scary. just a tad.,

 

I hope they know that...

Or I hope they video the first start up...

 

This looks like it should work they will just be firing 2 rotors at the same time jumping down the line I would assume. My guess the timing would go something like this Rotors # in order ( 1, 2, 3, 4, 5, 6) 1 + 4 fire then 2 + 5 fire then 3 + 6. That's just my guess i could be wrong. But in all i want to drive it and watch everyone cry in my rear view mirror. LOL

 

 

Everyone is wrong about why the world is going to end in 2012.

If this engine works ... it will have enough powa to cause the earth to break orbit

 

They should be more careful... she might get sucked in!
