ive talked bout this before and i know that rotars u times by two,does anyone know whether u would have trouble finidng a engineer that would let u do a 12a bridgeport into 1200 ute? i think for a road car that would be a really cool engine to have despite the very poor fuel economy, ive heard that the new rx8 gets only twenty something mpg, my parents auto v8 commodore gets 32, so surely an old 12a carby rotar would be alot worse.
