There are too many factors that determine who wins a race. And I'm not gonna mention all of them.

I think hes asking "all other things being equal"
The torque is just the highest number of of torque the engine hits, reguardless of engine speed.
HP isnt as easy as plugging torque into an equation. Its for this reason that 4 cylinders can kill us with hp/liter but we win in torque/liter.
so, all things being equal, same car weight, same traction same HP and same driver gasket
a torquier car is better for a race.

those that understand what you measure is torque and HP is just a caculation have it right. All the changes you do to your engine is to change the torque output and at what RPM range it makes the most torque. Movng the torque higher in the RPM band will raise HP numbers because of the math. The key to quick ETs is to match the peak torque with the RPMs you run. Ideal would be to have a flat torque curve that matched the RPMs from shift to shift. Most push for higher HP (higher torque at higher RPM) to match with top speed at trap.

Gearing and weight also decide the 1/4.
ex. s2000 vs 350z
Same times in the 1/4
350z has way more tq and more hp/lb ratio
s2k weighs less and has better gearing for the 1/4
Both are equal in the 1/4

Everything else being equal:
one car has 200 hp and 250 lb-ft torque,
the other car has 250 hp and 200 ft-lbs less:
Car with more Torque wins 1/8th
Car with more Horsepower wins 1/4

Not sure I understand your logic.

TQ gets you going and HP keeps you going.

Where as hp takes over in the upper RPMs of the power band. The car with more torque will push through the 1/8th faster, the car with more hp will push through the 1/4 faster. After the eighth you're spending more time in the upper power band.

So what you're saying is, if one car had 500RWHP and 400RWTQ, and the other has 400RWHP and 500RWTQ the extra 100 RWHP don't matter? Dude..you seriously need to reconsider that little ditty. There are TOO many variable to simply answer the question yes or no.

There are too many variables, maybe even enough to take an old saying with a grain of salt.

Code said it best.
TQ gets you off the line because it's a low rpm "function", generally speaking.

In my car, I turn it to 6200 RPM to shift and finish the 1/4 trap at 6200 rpm. If I use 1st and 2nd gears for 1/8 and 3rd for 1/4, how would I spend more time at high RPMs after the 1/8th?
