Re: How can I squeez 275hp outta my H22a

H23 crank and overbore to 2.4+L (obviously involve resleeving). The most aggressive cams you can find, the highest compression pistons you can find combined with a shaved head and/or thinner head gasket, should give you 13+:1. Get the thing tuned on avgas and I guess you should hit around 275whp. Also probably want a Euro-R IM port matched to a 70+mm TB or even better run ITB's. Dude probably meant on pump fuel though, which would limit how high a compression setup you could get away with.

Spending like $10k to get a couple of hundred in dyno time seems rather silly, although if "your dyno" means that he will buy you your own dyno, then I guess those things are worth over $10k?
