mke said:150-200 hp/liter from a boosted street-able engine seems very reasonable to me. There are also a good number of example in the 300 hp/liter range but is harder to make it play nice on the street and it pretty much seems to be the domain of computer fuel and spark rather than the easier/cheaper mechanical stuff, at least if its to be street-able.....so what is you plan here?
Honestly.... 300 HP/Liter is what I want. I'd love to hit that magic 1,000 HP number, just because. I'm not made of money, though, so to be able to get anywhere close, it's going to take me a while to get the parts and machining done.
But these days, power is the easy (if still not cheap) part of the equation. I've been spending a lot of time working through a bunch of suspension system info, trying to make reasonably sure that I can get the power to the ground, and turn corners, even with beam axles.
I won't be complaining if I don't end up with a four digit dyno sheet, but I will keep going if it's not at least 600 at the wheels.
As for my plan, it's 'street driven road/autocross race car'.
Oh, yeah - I'm also building a steering wheel...
