I don't know too much about cars...What does horsepower affect and what does lb/ft. torque affect?

 

april fools?

 

 

No...seriously

 

In car terms, torque is the outside force. It is what actually moves the car. Horsepower is derived from torque, and is relative to time. In order to address these terms you need 3 things force work and time

tourqe bascially is what gets the car going but once it gets higher speeds then hp keps it going

 

The more have of either one, the more you want.

 

Alright thanks. I asked because I was looking up intakes and the Injen adds 17hp & 16 torque( or somethin like that) and the AEM adds only 7hp but 17 torque...

 

Hey 116Fanatic; check out http://auto.howstuffworks.com/horsepower.htm I think that will answer some of your questions.

 

Not to high jack your thread but when I read your signature I just wanted to say hello, Hallelujah, and Amen.

 

Thanks for the help & the hallelujah. That site cleared up a lot...but I still don't see how the AEM adds 17 torque and ONLY 7hp because they seem kinds directly related?

 

sigh,

torque is what matter, hp doesn't keep you going on the "top end", rather, the rate at which your torque is falling off from its peak is what keeps you going (in relation to the engine's rpm past the peak tq rpm)

HP= (Torque x rpm)/a constant (can't remember the number off hand)


so really, to make hp you either turn the rpm high or make a crap load of tq at a lesser rpm.... this is why you can have 2 cars making 1000hp, one at 9000rpm, the other at 6000 rpms...
The idea is to set your car properly for either motor, and both cars should be as fast

Also, your rate of tq at which it is falling off will affect your hp. Changing cams usually keep the falling rate prety low, so you end up with more hp on the top end (at sometimes the cost of lesser tq towards the low end), this also called a curve switch to the right, meaning the hole tq switch over to the right (in relation to the rpms), so you may produce the exact same amount of peak tq, but at a diff rpm, thus producing more hp.

that is all for now

 

 

Don't you mean 5252?

 

I don't know if it is different on a relatively stock S/C car than on a stock turbo car but on the SRT-4 an intake will not give you 17 HP / 16 lbs of torque. You might see a 3 hp gain but that is like it. Now on a big turbo (so maybe on a larger S/C) you might see a larger gain like 7-9 but I just don't see gaining that much with just an intake.

Usually if you want a decent gain for the money, swapping out your exhaust is a good way to do it. Exhaust should aways be one of your first mods done to the car. After that it is relative to the car and what your HP/TQ goal is.

Sorry, I am on here trying to learn more about the Cobalts since I have two friends that own them. That and the base has SRTforumdotcom locked down so I figured I can surf CobaltSS.net while at work and SRTforumdotcom while I am at home.
