best n/a horsepower:litre ratio?

[chuckybob]

after doing a little googling, it seems that some f1 cars got up to 267 hp:litre, and it makes me wonder what's possible. (for reference, e30s tend to have a ratio between 50-70 hp:litre). what's the best naturally aspirated horsepower to litre ratio youve heard of?

i dont think youre going to find anything that tops an f1 car

fo sho, but i was wondering how high it can go without several million dollars in r&d. after a little more digging, s2000s have 120:1 and a hayabusa sport bike has 142:1.

There are RC cars that have like .25 cubic inches of displacment and more then 3HP. They also can spin over 40,000rpm.

thats 750:1. holy shit.

um wankel motors can do amazing 200 some odd hp out of a oem 1.3l. someone told me once upon a time that the s2000 has the best specific output in a n/a prodo car.

[chuckybob]

its actually 178:1 on an rx8

2 stroke will always win. Hence the outputs of RC cars. With fewer parts they can spin faster and have less loss in the mechanics. Rotary is the next best thing.

the 6 intake port, manual tranny is 238hp, from mazdausa.com

We should all just buy old Saabs.

I didnt address reliability. Anyone who owns an old 2 stroke chainsaw knows what im on about.
