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.

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/
