is 300 WHP (N/A)reachable with 10.5 compression?

is 300 WHP (N/A)reachable with 10.5 compression?

to end an argument I'm having..:D

[MrK]

yup. 400 even... (s62 lol).

With an m20b25... don't think so.

[Beej '86 325es]

right... :roll:

I don't remember the exact numbers, but I heard BMP's E30 (when it had a tricked out M20 in it), was only putting out somewhere in the range of 220-250. And that was 11/1 CR with individual throttle bodies.

What about if you sourced a Racing Dynamics 24v head? I am thinking that displacemnt has a lot to do with this, that is why usually the higher the liter the more power you can squeeze with out FI.

[MrK]

AFAIK the RD 24v head only exists on paper. I've never known one to exist in real life. So that kinda takes care of that option :P

[Ryan Stewart]

Well volumetric efficiency is pretty important. Most production engines arent all that efficient. You can make an engine 4 bajillion liters but if you are only getting a liter of clean air and gas in there on each revolution then its not going to do you a damn bit of good.

You might be able to get 300whp out of an M20 but it isnt going to resemble anything you had before and you could have bought an E46 M3 by the time you were done (at least).

[german g]

Ooops, should have put M20, with any mods, just has to stay at 10.5...

[Ryan Stewart]

Well, if you can get its VE near 100 and make it turn 10,000rpm its possible, in theory.

[PeaveyBassist]

Possible with a bajillion dollars? Yes. Possible with a couple thousand dollars even? No. At least IMO.

Not going to happen. Plain and simple

[Stu]

No, with the camshaft necessary to pull that kind of power, you're going to need to bring on more compression than that. (Plus you'd be getting very few hours out of it)

[chuckybob]

its possible, but i doubt it can be done on a 2.9 litre m20. needs moar 4 litre.

huh?

No. In fact, I would venture to say no where even remotely close. Actually, I don't even think 300 at the crank would be realistic.

[2002maniac]

Possible with a turbo and race gas.
