on a reg engine that say..redlines at 7k rpm, if one could just magically give hp and tq,

what would u give more, hp or torque? and how much more becomes negative?

 

Hp is relative to Torque, Torque is the measure of actual power.

 

beat me too it

 

here you go dude

thanks alot...that cleared **** up for me.

so basically..a typical ls1 would greatly benefit from some extra RPMs, since i see qutie often more tq than hp to the ground...

it shows a tractor making 1000ft at the wheels at 1200RPM, and a old cobra engine making much much less..but spinning at 5600rpm.

they ended up having the same hp. so the ls1, for example..would benefit from being spun higher.

this would explain the new ls7 rumored to make 500hp, with 6.0l but spinning to 8k rpm.

 

go look at a H/C car and tell me what you see

 

im confused here
the webpage said if you want to launch,
you should get as close to your hp peak them dump the clutch
is that true? i mean,
lets ignore the traction issue for a second.
if you would hook up no matter what,
would it be better to launch from peak torque or peak hp and why?

ls1 peak torque = 4400 peak hp =5700 i read
the best performing stall converters are ~4400

 

Your confusion is warranted. There is some slightly incorrect info being passed around here.

Check this instead:

http://vettenet.org/torquehp.html

"Any given car, in any given gear, will accelerate at a rate that *exactly* matches its torque curve"

Notice your horsepower curve has nothing to do with it in any particular gear.

As far as cars are concerned, horsepower is how long you can hold on to any given gear before shifting to a higher gear (which greately reduces the torque available).

"horsepower has nothing to do with what a driver *feels*.

You don't believe all this?

Fine. Take your non turbo car (turbo lag muddles the results) to its torque peak in first gear, and punch it. Notice the belt in the back? Now take it to the power peak, and punch it. Notice that the belt in the back is a bit weaker? Fine. Can we go on, now?"

That article I linked should clear up some questions/confusion for everyone here.

Repeat after me. "It is better to make torque at high rpm than at low rpm, because you can take advantage of *gearing*."

 

great article!
