as title says can i squeeze 280rwhp out of a properly setup PP 12a

and

Is it possible with a carb?

BTW could care less about streetabiliy of this setup, it is a bet i have with a buddy of mine. he says theres no way 280rwhp outa a 1.1 liter NA

 

I'm not sure about 12a pports, or 12a's for that matter, but you could get 280hp at the flywheel probably

 

It's possible, but not with a carb.

The early '80s GTU teams were making about 280hp with fuel injection and Mazda peripeheral port rotor housings. When they were forced to switch to a carb, they lost power but got back up to 280hp by altering the port window to a square shape instead of a D-shape, which also made the powerband narrower.

Perhaps you should be more pwrried about the area under the curve instead of a single peak HP figure. 99% of the time, the engine is not running at peak HP, it's above it or below it.

 

PJ, where do you learn these fun facts?

 

Got my methods.

 

I havea a Buddy Here in portland, who has a rx-3 PP 12a. sais dynoed it at 325 at the flywheel.
He also has about 15 g's into his motor.
But 280 hourse is possible.

 

Talk to Brian at Rotorsports Racing here in NC. He has been contracted to build 12a race engines......price range I believe was something crazy like 20k per engine. http://www.rotorsportsracing.com/
