New 2.0 I4 NA

Anyone want a small, super light and powerful 2.0 I4? Here’s what i have done, you can run it richer to get a few more HP but i think it’s not worth cause then the fuel economy would be ridiculous.
I think it’s a really nice engine for something like a Radical, a Caterham, an Ariel Atom or so.

Nice engine, really well done. I noticed your exhaust is too restrictive, though. Going to 2.75" pipe freed up another 8 hp and lowered the octane requirement.
