12 rotor engine
Guess I'm just so used to typing RWHP that it came out of me automatically. Thanks for keeping me honest!! 
the raw piece of material costs me quite a bit more then that..
again this may not be cost effective for a stock housing, but if you already had your exhaust housing ported alot and did not want to buy a new one and do it again then this may be worth it.
how much is a new housing going to really cost someone?

here is a video of the 12 rotor doing some low power testing on the dyno.

when the secondary's on the carb start to open it did not have enough fuel so it leaned out so bad it would almost shut off. We put a nitrous plate under the carb with fuel ran to it but then flooded it. So we took it back off the dyno and were working on the fuel injection intake.

BigYellowCat, not sure if you've had any issues of resonance or deflection with the gears meshing the 3 engines together...but if so take a look @ pg. 15, Figure 47F. Very interesting idea. Seems to have eliminated their issues with it. Also the "roots-type" froth pump...

EFI installation is almost complete. Dyno round # 2 coming up in the next month if all goes to plan..

little update,
The fuel injection system is on the engine, fuel rails, 24 id 2200cc injectors, 24 coils, Adaptronic computer, we burned up the starters trying to get all the sensors set up on the engine so we have not dynoed it yet.
I have a big job that has taken most of my time but I should be done with it in the next two months then I'm going to start working on the engine again.
Here are a few pics.
