V6 or 4 cylinder

For the car I would guess S2000, the truck.... S-10?

You bring up a point. Torque is the other really important thing that is always left out of discussions like this.

s2000 and tacoma with the 3.4 v6

A ford 427 never had the power that the 426 Chrysler hemi had in its best day. At daytona it was so bad that the 426 Hemis had to de-tune them or be banned as they were winning EVERYTHING! I love muh Fords in the day..... But thise 426 Hemi's ruled.

Perhaps the standard 427 4 bbl, but Ford built 2-3 different model 427 SOHC engines in the mid 1960s that could be ordered over-the-counter that would put out from 620 to nearly 700 hp, I think referred to as the Cammer.

Phaedrus... Your a good guy... But after reading your post this exact image ran through my mind

Now THAT is funny. Sorry, I already gave out too much rep, today!

Torque is more important than HP. If your torque numbers suck, it doesn't matter what the HP is. You won't be able to apply it effectively.

That is why the STI rules. 300 hp and 300 ft-lbs of torque. Pretty impressive for a 2.5 liter 4. And then add the fact that all 4 wheels apply that power and torque to the road. BIG fun.

Alas, fun I can't afford.

Horsepower = [Torque (ft. lbs) X RPM]\5250

Both are important, but if you are talking speed, HP is king.

For instance, a indy car has relatively low torque but can spin really fast, making gobs of HP. Crotch rockets are the same way.

A semi truck has gobs of torque, relatively low HP (low RPM's). Harley Davidson's are the same.

Which examples would win a race? The RPM's have a multiplyer effect on the torque, ie 1 ft lb. of torque can do twice the work at 200 rpm as it can at 100 rpm.

I think 7000 HP would win most 1/4 mile races!
