hp sells cars, but torque wins races, does anybody have those numbers?

power to weight wins races and driver skill win races,

hp and torque numbers satisfy auto-erotic urges.

+1

Comparing one car's torque to another car's torque rating does you absolutely no good.

Really....My friend's turbo tc was running the same whp numbers as my s/c tc on the same dyno. His being bone stock except for the turbo itself (stock exhaust). From a roll, even when I got the jump on him, he still pulled on me pretty hard. Going back to all my design classes, torque at a given rpm will give the rated hp at that rpm. Having said that if my friend is making tons more torque with his turbo at a lower rpm, he's going to be making a more hp than me in the midrange. This futher proven when looking at the linear hp curve of a s/c tc vs the curve of a turbo that makes more torque. You can't have hp without torque.

This has been my understanding of the torque and hp relationship as it was taught to me. If this is wrong in any way please tell me. If it's one thing, I'm always trying to better undertand these things.

You sure got it! I meant you can't compare between two different cars like a Charger is different to a tC.

When comparing two like cars then the car with the dyno graph showing the greatest integral under the torque curve will show you the faster of the two cars. You can ONLY do this with like cars since one lbs-ft with different gearing and different RPM means different things for different cars. So you're completely right in that, two like cars, with the same peak hp, of the two, the one that makes more torque earlier will be faster.

If one really wants to bench race, you need to take two dynocharts and compare the power curves. Since there's only one speed associated with every horsepower in a given gear, you can look at the power curve as a speed graph. The integral of the power curve is the distance covered in a given amount of time. So isolate the part of the power curve that you're going to be drag racing in and take both integrals. Divide the integrals by the respective weights of the car and the car with the highest power to weight ratio over a certain range of RPM wins the bench race.

Got ya. I though we were rulling out torque all together.

Horsepower is derived from torque! How can we let go of torque then? :D


But it'd be stupid to say a tC is faster than a new Si because the tC has more torque.

horse power=torque X rpm / 5252
i think that is the formula

im sure to get that 12second run they had higher octane gas and slicks and what not. if you still have factory tires 350whp would b tough to handle. 1000whp isnt much if it cant stick it to the ground hahaha

It's faster than the new Si (stock) when you put a turbo on the tC with minimal boost pressure 7-8lbs.

the tires were DOT approved Drag radials, not Slicks. Wether it was race gas, I doubt, but am not 100% sure. Just ask Mikescion.

Whats it matter, he ran a 12.7 and not very many people can beat that time. BACK ON TOPIC FOOLS

all I am saying is if he wants to recreate, or attempt to, 12.7 you need ot have equal or better componets.

To the original poster...

Someone compared the SRT-8 to the GTO. Giving that comparison, and me speaking from experience and not hypothetical bench racing... A ZPI Stage 1.5 should take out the SRT-8 from a roll. From a stop, put some Drag Radials on so that you can make it even when it comes to the launch (RWD > FWD, but FWD with DR's evens it out).

I base my opinion on the fact that I've raced a GTO. He did a ricer flyby on me first, to see if I would bite. Then we came upon a stoplight side by side. I looked over at him, but he never glanced my way. So, I figured he didn't want to really race. Light turns green, and I just roll off normally, with the GTO starting off slower than me. I make it to about 2nd gear, and the GTO is about a car behind me when I hear him down shift and romp it (to do another ricer flyby). Me still rolling in 2nd gear, he comes flying by. I decided to just mash and see what happend. When I went to mash the gas, he was already half a car in front of me, and when I hit boost, he was a car ahead of me. When I hit boost, that was it, he couldn't pull me at all. And the tC was only on 7lbs of boost on a Stage 1.

not to be off topic but...what the heck if you want to race then race whats with the staring foward crap then stepping on it when you know the other person is not in an advatage gear wise.

but im sure a zpi 1.5 would have some fun with the srt8

yeah, the guy that was rolling with me, said that they do that a lot down there (Columbia, TN). they like to just take off on you and get the jump, which that was all he did, get the jump. he was impressed with the tC that I could keep up with that GTO. I turned to him and said, if this was a real race, I would beat him. he was like really? I said hell yeah, I didn't even launch the car, and the guy come flying past me... I honestly did not think he was racing, cause he never looked over, nor did he rev or anything. So, I just rolled off normally.
