Why aren't the SS' running high 13's 200+ whp stock?

I think hp definatly plays a roll in good runs. My truck has enough torque to rip a house off its foundation without breaking a sweat, but seriously lacks in the hp department. My trucks fastest run (15.63 @ 85) had conciderably faster 60' and 330' times than my cobalts fastest run (14.59 @ 98), at that point the truck was moving but didn't have any hp to take it the rest of the way.

You all walked right into this one, You helped me prove my point. You all worry about peak power, what will part a or b dyno at peak. When you are only spending less than 1 second of 13 sec run above 5800 rpm, what good will a few HP at peak make? Give me 20 HP in the 3500-5500 band and wathc it give you more bang for the buck!
My peak HP never changed much in my modding but mid range TQ AND HP increased dramatically. In other words, i added allot of useable power, not peak power.

Wow, mature post. Why are you allowed to be on this board then? You don't even own a cobalt, nor contribute any helpful knowledge about one.

Tell that to the S2000 i HALFTRACKED this past tuesday. I think he ran 14.8@92 with MORE HP than me!!!!!!!!!!!!!
Yea, TQ means nothing

If you want an even better time in the 1/4 mile, try power shifting. It shaves a couple of 10ths to a half second if you do it correctly. Most people don't like to do it though.

Does an accelerating car follow its horsepower curve or torque curve?
Who would care about how a car's speed is sustained?? I don't get it.

Cobalts arent into the 13s because it wasnt made for the 1/4.
The cobalts gearing/suspension were not developed with american style drag racing in mind it was developed off the nurburgring and othe road race corses by europeans.
To bad we dont have an autobahn.
Also the car has four big fat ass 24 pound rims that hurt acceleration.
If the car were rear wheel drive with slicks and ideal gearing it would be a mid 13 second car.

An accelerating car follows its torque curve. Where the torque peaks is where it changes velocity at the greatest rate, which is acceleration.

In very simplistic terms: Torque accelerates you to a speed, HP overcomes everything that is trying to prevent you from maintaining that speed.
Its very difficult to explain past the point that there isnt much difference between the two. If you dyno your car, and then sit in it an feel when the car is accelerating hardest, you will find that the hardest acceleration happens at the torque peak, not the HP peak.

Someone who was racing. Torque tells you how much power is being put down at that instant. HP tells you how well the engine can put down power over a period of time. Torque can be measured in one revolution. Its how much work is done at that moment. HP has to be measured overtime, because it is describing how much work is being done.

Oh well here's another article I found about "Torque vs. Horsepower" if anyone is interested.

This guy has been in every Forum,, Trying to show how smart he anit & does nothing but try to argue! Have not seen 1 How to from him>>>Secound I look at threads he started>>>OOps there aren't any! So either try to get along with the rest of us or Post something usefull! Or Dont Post at all!

He uses lots of different names and needs attention.

Finally, somebody knows how hp is measured. when 5252 rpm is mentioned i know you know what you are talking about.

Torque x Rpm / 5252 = hp. That's all you need to know. That is why high revving engines such as hondas make far less peak torque then peak hp. Torque is an actual measurement...hp is more of just a number. horsepower is used because it is a better measurement to make an estimate of how quick a car is. Look at the 06 civic si for example. 197 hp at that weight seems about right to run the times it does, but 139 ft lbs....that seems impossible, but it is a very high revving little engine, so it makes bigger hp numbers with less torque.. All of you need to stop arguing a stupid point, torque and hp are important, but not peak of either. It's how much you have across all of the rpm's.
