You mean when you show them Torque isn't everything?

From another thread:

So what is rolling and wind resistance going to require. Just like to get a car going initially, torque is being used for a moment then hp takes over.

Wouldnt the same apply with wind resistance and rolling resistance. Wouldnt the torque be used in this situation to overcome that?

Again at some point the extra 70 ft-lbs of torque from the turbo car is going to be used correct.

Again how else would you explain a 210whp ve and 210whp but 210wtq turbo car taking less time to get to 140+mph. You say its the hp but both cars being the same as far as gearing and tire size and so on. Explain this, the Hp VS Torque thread was useless in answering this question. Too much conflicting crap.




I'll break it down for you Ashton.

Everyone needs to stop thinking like this. Torque does not move a car. Torque cannot move anything. Forget that concept. Power moves the car, always, at all rpm, forever and ever, amen.

See above.

No. Well yes, but no. Not in the way you're thinking. And no. No no no. Just forget about the damn torque. The only thing torque is used and is useful for is to make power. Do you factor in how much fuel is in the tank when you calculate acceleration (aside from the weight of it)? No, you don't. It's used to make power, same as torque, and that's all we care about; power.

The 210 peak WHP turbo car has MORE POWER. Let that sink in. It has more power available. End of story. That is how it out-accelerates the other 210 peak WHP VE engine. It has mooooooore pooooooower.

It is the horsepower. Yes, both cars are the same, except the turbo car in your example has more power.

Questions?

I've always seen it as "More torque down low = Earlier Horsepower".
