Horsepower and torque equal how many seconds (tenths, etc.)
I've seen where two cars may be similiar and one car has 100 hp more than the other car, but has only a .5 second advantage. Is there a set, or near set formula, or a theory for knowing how much horsepower and torque that will translate to time; such as 100 hp/ 100 foot pounds of torque equals .5 seconds or a second or some unit of time.

Nope. Peak hp is not where it's at. It's when and how long you make a sustained amount of power. Some 800+hp cars still run 11's, while some 350hp cars also run 11's...there's really no way to tell by a number. That's why we don't race dyno slips. [8D]

98 is right. Things like weight, traction and weather also come into play. Also there is a point of dimising returns, in other words say a stock 95 GT with 210 hp goes high 14's, now add 50 hp and the car goes 13.90's, you would then think that another 50 hp will make it run low 13's right? But thats not how it works. There comes a point at which an increase in HP will give very little gains in perfomance. A great example is NHRA, a Pro Stock car has aproximatly 1500 hp and they run low 7's to high 6's now a Top Fuel car has over 7000 HP and they run 4's so it took 5500 HP more to drop 2.5 or so seconds.
