is a 3.5liter 240hp VQ better or is the engine offered on the S2000 2.0 240hp? or which would do better, 3.5liter 260hp, or 2.0 260 (with exhaust work)?

off the line, I would go with the VQ no second thoughts. You have to rev the hell out of the s2k engine to get it's true performance. you know what they say: there is no replacement for displacement.

Without a dought the 3.5 260hp. What the 3.5 has is torque. That little Honda motor only makes good power WAY UP HIGH, like the rung out formula one motors.

so the VQ makes decent power all throughout the power band, correct?

correct......flatter torque curve....

and one more.. a bmw 282 hp v8 would be better then our v6 3.5 with 282.. rite? same concept i belive.

All of these questions depend on the exact shape of the torque curve as well as the gearing in each car. Without knowing those exactly, we're just speculating.

Better to do what? The VQ and 4.0L have more in common than the S2000's does, but they are used for completely different purposes. Please elaborate.

overall.. powerband torque curve, low end, highend. ect ect. wutever u know about the advantages/disadvantages, post, im just curious. and by the way, why is it that the more the cylinders, the less RPM they rev up to?? and how come a Inline 4 can rev up so high, and our v6 will have "problems" and "engine damage" doin so?

A rally car like the Saab 9-3 is only 2.0L l4 twin turbo. It reds at 4k, but produced 600hp and 600lb/ft Max! It hits 60mph in 2.4seconds

Many of those so claim "1000hp" hot rod with V12 and 7L ran 0-60 in 3 seconds flat.

Go figure.

AznWontonboy

woah.. u sure about the 4k and the 2.6 seconds?? its hard to belive, but if i do see the facts.. hmm im gonna go check it out.

Umm, a rally car usually has a higher redline than stock cars. I doubt the SAAB Rally car has 4K redline and does the 0-60 sprint in 2.4 seconds. The only car that does that in under 3 seconds would be the Porshce Dauer 962.

The VQ would be better because it has 240 torque and the S2000 has 153 for torque (at high rpm) and it's torque that move your car and HP (1HP=0.746KW) is what you use to light up a light bulb .

The reason that the S2000 number is so high is because it's peak torque is at high RPM and since HP is a function of torque and RPM [HP=Torque*RPM*(2*pi/33000)] the more torque you can keep at high RPMs the more HP you will get.
[Example1: If you look at a before and after dyno chart of a max with a y-pipe you will see that what the y-pipe does is make the torque fall-off at high RPM not as steep and since you have more torque at the high end you will get a bigger HP number.
Example2: If you got NOS and you decided to only run it at low RPM to have low end torque and minimise engine stress and you programmed to give you a flat powerband from 1K RPM to 5K RPM instead of 3-3.5K RPM to 4.75K RPM stock you would have much better acceleration but your peak HP would not change since you did not do anything to the high end torque.

Also the S2000 is a very small and light car which is why it gets decent performance numbers with the I4 engine, if you put the S2000 engine into the heavy max you would get better acceleration if you got out and pushed (exaggerating )
