how much could this be! the loudest MOTHERTRUCKER ever ??? how is this accomplished ???? have they ever used 13b rotors&housing's ?

OOOPS!

 

i have always wanted to do that... more info?


I have seen places that will make custom 3 and 4 rotor Eccentric shafts, i think the rest could be done with just the parts from several engines.

 

Custom built by a local shop.. heres your info

Who will make one, that has expirience?
What about ignition?
I'd like to see dyno numbers.

 

It's right on the page, dude.

I wonder why people are putting together 4 rotor 12as and not 4 rotor 13bs... Length maybe? This one makes the second one I've heard about lately, the last one was from video option. A tuning company named Scoot (I think) out of Japan did something similar with the 12a.

 

Actually, with the ignition, you could run a dual fire setup almost as easily as you could with any other rotary, you'd just need to modify the dizzy to fire every 90 degrees instead of 180 on a 2 rotor and just go without the trailing. At least, in theory.
Back me up on this jeff20b. lol
I imagine they're running a 13b or 20b CAS and full independent engine management, though.
I'm more curious how they modified the intake plenum and lower manifold... Looks damn near stock 20b.

 

Absolutly insane !

 

i want one...

 

And think about this:

on the same page they've got a 1st Gen 13bREW.

So they took a 1st gen and a 3rd gen
- swapped the 13BREW into the 1st gen
- took the 1st gen's 12a and another engine, and custom built the 23a

All it took, really, was another donor 12a and some custom machining! Pretty smart set of swaps, really.

The R&D of such a project would be VERY expensive and not practical for an individual............though very cool,,I will stick with a 2 rotor

 

beautiful words could not describe the joy of that engine!

 

All I can think of when I see that, is damn. $5.99 for good spark plugs.....and now you need 8.

 

i wonder if a E shaft that long would be detrimental at all for HIGH rpm use... like 9-10 K...

 

I don't see any info on the shaft on that page. that's what i was refering to.

did you say dizzy? we live in ky dude.

I'm sure it would cost 2k at least to build one, but I'm thinking, it would make great power(reasonble) with minor porting, and be very dependable.
Is almost twice the engine weight though.
What about oiling? just one pump i assume?
