the F1 engines that run really high rpm use a short piston movement with a long linkage to multiply it back out, it lets you rev over 20,000 rpm without your piston tops breaking the speed of light.


to make a high HP A15 - turbo(or whatever to get the cr up to 12:1). burn decent octane fuel, use real EMS.

everything else will just get more.

you'll need lots of cooling capacity and and oil cooler too.
