that;s the whole frickin point dude, wake up!!!
do some equations and get back to me



i dont need to "do equations and get back to you". lets have a look how this started;

oldcorollas wrote on Tue, 24 June 2003 17:17

as for torque not being important? you tell only half the story...

rusty wrote on Tue, 24 June 2003 05:37

on a side note: torque is often mistaken by those with little or no grasp on the relevent concepts as being more important than power. usually by the same group of people, oddly enough, who think turbos are for small engines only, and/or inferior to superchargers.


i think a review of the concepts is in order.
two cars with same size tyres, one with twice the torque at the wheels at the same car speed, and thus twice the force at the tyres circumference acting on the road..... you tell me which one is going to accelerate faster ( A = F/M)

the power issue is misinterpreted by many ppl to be most important. a famous quote(and i can't even remember who said it now..) was "power sells cars, torque wins races" and that is true.



lets not meander from the topic. the only logical interpretation of the above is that you think torque is more important than power, yet;

hell, i'll even spell it out for you.
F1 has 3 times power because of higher rpm.
...
F1 car acclerates 3 times faster.



and secondly;

sure power is a convenient way to measure motors, but it really doesn't mean that much.

WHAT IS IMPORTANT is the TORQUE an engine makes and the ENGINE SPEED (rpm) that it makes it at.



(and right after that...)

this is good. however the first part (and i quote again; "the TORQUE an engine makes and the ENGINE SPEED (rpm) that it makes it at") equals power. funny that.



well duh, that's what i've been saying all along.



cant you see these are conflicting sentiments? they are mutually exclusive. you either go with one or the other. if you think torque is more important, fine. youre wrong, but thats less stupid than thinking both the above are right simultaneously.

you have an obsession with torque, when torque is only a component of power, the other part being the rate it is applied, or rpm. i said at the beginning that power is more important than torque, because obviously if you have the one, you have the other. yet you interjected to the contrary (above). that has been my disagreement with you from the start, and continues to be.

torque doesnt win races, matching the power curve to your gearing wins races. ie F1 - peaky high-rpm power, 7 speed close ratio boxes, and the ability to shift them in thousanths of a second.

repeat 3 times after me, power moves the car. not torque.

still disagree? with only torque, there is no motion component. as soon as motion occurs, work has been done and thus we are discussing power. by disagreeing with the above youre failing at simple interpretation of the very equations you keep trotting out.

rusty wrote on Tue, 24 June 2003 20:29

now allow me to pose an alternative question. one engine with 500lb/ft of torque and only 100hp, another engine with 500hp but only 100lb/ft of torque. both engines in two completely identical cars, with the only exception being gearing, any gearing being allowed. you tell me which car will be quicker. if you still think its car a, im afraid there is no hope for you.



oldcorollas wrote on Tue, 24 June 2003 21:12

LOL ROTFL
so you want me to take a car with 9.5hp (500lb/ft@100rpm)
and race you with a car with 500hp (100lb/ft@26260rpm

dude lay off the drugs, who the heck do you think would win???



no.

pay attention this time. i said;

one engine with 500lb/ft of torque and only 100hp
another engine with 500hp but only 100lb/ft of torque


who wins?

want to have another crack at it?

in case you didnt get the point, and it seems you didnt, this is to illustrate that power is more important than torque. which is what i said in my first post in this thread. if you had no disagreement with that then you shouldnt have responded to the contrary.

oldcorollas wrote on Tue, 24 June 2003 21:12

now please show me your calculations to disprove that two cars with identical POWER, but different TORQUE, when gearing is made to equal the top speed of both motors, will not have the same acceleration..

i dare you.. no i double dare you to brign those calculations to the forum, or even dyno day (if you will show up)

you can't accept that a motor with twice the torque but half the revs and half the gearing accelerates at the same speed as one with half the torque, double the revs and double the gearing...



you leading somewhere with this? what are you rambling about? why would i have any interest in proving this? try keeping it relevant, or at least respond to what i said.
