Mike, can you still get 12AT rotor housings?

Maxt, are you interested in doing some peripheral ports?

Yeah I can do them , as for the housings, I know I can get them out of Japan, the cost depends on what kind of rush you are in to get them.

That sounds good. I'll get with the owner and let him know. Then I'll get back to you.

Im seriously considering doing this, but just a two rotor 12A.

The Peripheral ports I can do at work, fabricationskills are present. Only thing i need to know is if my carb is large enough.

I have a 45mm OER sidedraft carburetor, will it be sufficient to support the 40mm port i plan on running?

What is an OER carb?

With a big bridgeport and 36MM chokes in a 48 IDA Weber, My 12As get 173 HP at 6,500 RPM and at your red line of 8,400 RPM have 238 HP. Top HP is at 9,400 RPM and 244.8 HP.

So, carb size is adequate for the displacement and RPM you want to run at.
