I noticed on most dynos the peak torque is higher than the peak hp. I know this is especially true with n2o. When my car was dynoed, could only squeeze 2 untuned pulls this day, my hp and torque were almost identical. Basically i wanna know what determines for the hp to be more, the same, or less than the torque output? This comes down to me not totally understanding the difference between the 2, i've heard the saying " horsepower sells cars and torque wins races" but dont totally understand that either,lol. Thanks for any help

cars with a unlocked high stall will do that too---high torque, low hp

well, a person would rather buy a car with a ton of horsepower then not and torque gets u moving. look at it like this, torque gets u moving and horsepower is what keeps u moving.

I would have to totally disagree with that based on my experience and a few others I have seen on this board.

Well, using my car as an example this was exactly what happened. When you first nail the gas on the dyno with a large unlocked stall, you get a false torque spike. Mine spiked over 400 ft/lbs when Jeff Creech first nailed the gas on the dyno. I think that's what 11SECDWS6 is talking about. All big stalled cars will have this false spike on the dyno. Too bad it's not legit.

Well...what do you call this:

409rwhp/493rwtq

And this: 464rwhp/504rwtq

Just for starters….

Torque is the force put out by an engine. HP is the work done by an engine. HP wins races, NOT TQ.

Torque and Horsepower are related to each other by RPM. HP = (TQ x RPM) / 5252. That is why at 5,252 RPM HP = TQ.

Torque is a generally a function of cubic inches. You can build a 427 LS1 with stock heads and it will still make around 510 Ft. Lbs. of torque, it will just be down big time on HP, so it will be slow.
