Actually, I'm not exactly sure how that dyno works, but I suspect the graph does not show actual rear wheel torque in 4th. It shows some estimation of engine torque/horsepower based on the actual horsepower & wheelspeed and the detected engine RPM. The graph should look almost the same regardless of which gear you do the run in. However, that won't necessarily be the case because I believe lower gears induce higher "losses" (from friction, etc) than higher gears do.

As for the multiplier difference, that's a 30-40% difference, so the actual rear wheel torque will be significantly different between 3rd & 4th gear.

Now there's something we agree on.

 

Simple (and correct) answer is that it is better to keep the engine in the max powerband all the time. The way to do that on an S2000 is to run it right up to redline before shifting.

It is engine power (as translated by the gearing into wheel torque) that accelerates the car. Engine torque is meaningless, except that it creates engine power.

 

By the way, I think all of this has probably been discussed ad infinitum when 4.10 vs 4.56 vs 4.77 discussions were popular.

 

Unless I'm missing something (which is possible), this statement doesn't make sense.

if you accellerate faster, you cover LESS ground before you hit 90. Imagine racing a prius, it's going to cover 4 miles before it hits 90.

So you hit 90 in less time and shorter distance, you're going to have more space to keep accellerating, AND you'll be moving faster, so your ET and your trap speed will be better.

I think the only way they DONT go hand-in-hand is if a fast car gets a bad launch. If you always had an identical launch, If you hit your best trap speed, won't you always hit your best ET also?

With an F20C you want to run all the way to the limiter in every gear to get the best speed at the end of the quarter mile. ET will be greatly affected by the launch (and reflected in the 60' time). 60' times tend to go way up when the pumpkin lets go of the ring and pinion, so the best way to *drag* race the car is with a good understanding of what it can and cannot tolerate without breaking.

 

Mike, area under the torque curve is what matters, but we've had this debate here before and it's just stupid.

 

Best way to drag race an S2000: buy a Camaro.

 

Thanks for all the members who actually helped and talked about it.
Shut the **** up to the members who was talking shit for no reason.. you must be THAT bored.

Thank You. Have a Nice Day. =)

I'm pretty sure the correct answer for the OP's original question of "Racing a s2000, what's the right way?" is:

[B]For pinks.
