ok simple question to be answered
 

I tried to explain to this ricer kid at work about torque and horsepower he dont get it.
he is stuck in his idea that horsepower gets a car moving and is the sole force required?
I tried to explain as simple as possible til I was blue in the face but I gave up.
ok anyway to explain these two forces in real easy terms and the relation between the two ?
(gotta keep it simple so a ricer can understand)

ok here is the way i have explained it to people in the past.....

tell him to think about the feeling you get when his car excelerates from a dead stop or in 1st gear ( low gear) and the "PUSHING YOU BACK IN THE SEAT" feeling you get.....tell him at whatever point he feels this feeling to be the greatest is more then likley the highest ( strongest point) of his cars TQ curve...
now tell him as he shifts into 2nd,then 3rd and 4th,,,possibly 5th and 6th gear...the "PRESSING YOU BACK IN THE SEAT" feeling gets less and less..but the car gets faster and faster..this is where the HP Curve starts rising and the TQ curve falls to its lowest...



this is the simplist way i know of explaining it to someone that truly dosen't understand the difference.....


now get him to imgaine..what his rice burner would feel like if he could KEEP THE SAME "PRESSING YOU BACK IN THE SEAT FEELING" he experiences in low gear...while he is in the highest gear he has and the highest MPH..

This is called 632 bbc on a 300 shot....lol

if he doesn't understand this..he needs a moped.

i betcha he doesn't understand why a car running 6.80et at 102 mph outruns a car that turns a 7.00et at 109 mph......

all they see is MPH.....

Explain it that way.

The way I learned it early on was this: Torque is what the engine makes.........turns the driveshaft. HP is a mathmatical calculation, measuring the amount of work the engine can do over a specified period of time.........More HP, the faster the engine can work over that time. I might be wrong, but if I remember correctly, 1 HP=33,000 lbs lifted one foot over a period of one minute................

Another way to look at it is 1000 lbs torque @ 500 rpm is only 95 H.P. that 1000 lbs will stand your car straight up when you release the trans brake but the 95 H.P. wont get it down the track at a very fast rate.Bill

i know this sounds lame but my grand dad told me when i was first
getting into mechanics, its like a fire cracker, the amount of gun
powder (horse pwr) in the expolsive, determines the size of
hole it makes in the ground (torque) and if you ever had a fire cracker
from mexico, theirs are smaller but can take off your hand, more
torque, less gun powder to make the hole (their dangerous)
but gear heads understand and can see how torque is the power
to lift and lanch a car, like the hole the fire cracker makes, if it
sounds dumb, i tried, but i understand the mathamatics of torque
from horse pwr.-my 2 cents :?

If the kids a real smart ass, tell him HP is how fast your fist will smash his face but TQ is how much its gonna hurt.

-torque wins street races (1-2nd gear, top out at the speed limit)
-horsepower wins 1/4 mile races (1-2-3-4+ gear at over 100mph)

challenge him to a street race to show him the differance :lol:

this is pretty vague but look at the big picture, a 200hp/400ft-lb car will beat a car with 400hp/200ft-lbs getting to 50mph but anything after that the hp dominates.

lmao thats one way to get it across.

damn he is hopeless he still turns his ideas around on the subject.
even after I let him read the post above lol.
I guess watching too much fast and furious will do that to ya.
Im gonna give up and let him make an ass of himself.
Well its already happening at work his so called 518 HP volkswagon GTI sounds like a popcorn machine with the tiny turbo and blow off valve.
and he cant tell me the torque the engine puts out and he says torque is irrelevent lol.

If the kids a real smart a$$, tell him HP is how fast your fist will smash his face but TQ is how much its gonna hurt

gnsrule......man thats just to funny :lol: you rule!

Ok tell him he has way more hp than my diesel truck. Now let's chain them together and I will demonstrate what tq is HEHEHE.

TQ vs HP
 

To some degree torque is the grunt that gets things moving, and horsepower is the force that keeps things moving.

On modern day dynamometers horsepower is a calculated value. It's important to remember the dyno measures torque and rpm and then from these calculates horsepower. On the dyno it takes more water flow to the water brake to increase the load on the engine being tested. As the test engine's torque rises more water flow is needed. As the test engine's torque drops less water flow is needed. The dyno's water brake does not respond to Horsepower. Major adjustments to water flow are needed as an engine crosses its torque peak but none are needed as it crosses its horsepower peak. In other words the water flow to the brake during a dyno test follows the engines torque curve and not its horsepower curve. Torque is what twists the tire, prop, or pump. Horsepower helps us understand an amount or quantity of torque. (Torque + time and distance)

I always heard that horsepower doesn't actually exist.That it's a measurement of torque over a period of time.I also have been told that 1 hp is the amount of energy required to lift 600lbs straight up one foot.If it can go 1 foot why not 2? don't make sense to me.TAKE HIM FOR A RIDE,THAT'LL CLEAR IT UP :D

Tell him is import ricer has neither! Then he will understand? :lol:

Re: ok simple question to be answered
 

Tell the kid to go and race a diesel pickup and he MIGHT win depending on the mods the diesel has. Then tell him to weight his little ricer to 7000 lbs to equal out the weight between his ricer and the diesel. Now he can race the diesel again and he might understand how the diesels torque just waxed his @ss. :D Maybe he might get it.
