How much power have people been able to get out of a stock displacment motor? Torqure and Hp?

I can recall reading about people getting 120hp from 1.7L type one motors years ago. That is on pump fuel.

With the technology available today I would think that volumetric efficiency could be pushed further than before while maintaining reliability on the street.

So is 130-160hp out of a 2.0 totaly (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

I know Porsche did it years ago with a couple diferant 2.0L motors like the 901/911 or 587 (street motors not track). However, they were radicaly diferant compared to the simple type 4. ....

You could probably get about 300 HP out of a 2.0 displacement motor.

For about thirty seconds. At a cost rivalling that of your average house. On some exotic type of fuel. With huge amounts of boost. After five years of development. (At many times the cost of the average house.)

Constraints are what give you an idea of where to go. You mention pump gas--that's one good thing to know. (Regular-grade? CA-super 91 octane? The 94 you can get some places? Something else?)

Forced induction or naturally aspirated?

How long is it supposed to last?

Is cost an object? What kind of budget is available?

Is a peaky powerband OK, or do you want a fat mid-range for easy driving?

....And on and on and on. Answer these types of questions (and many others!) and you can start figuring out reasonable limits.

Water cool the heads and add bi turbo. Maybe not three hundred, but an easy two.
