I totally agree with you...the torque moves the car, but seriously the torque curve does NOT fucking define the maximum acceration point..THAT IS MY FUCKING POINT.

I am defensive because im not gonna agree with something thats not correct...

maximum horsepower and torque peaks define maxium acceleration...simple as that.

Trucks are fucking slow but make soo much torque...
F1 cars make a shitload of hp and not alot of torque but can move like rabbits...

regular street cars have a little bit a both so the acceration from a deadstop is very good, but they dont have to go through 20 gears to get up to speed because the horespower curve lets the torque get used much more.

engines need both hp and tq to accerate as fast as possible. I am just saying torque is doent define shit when under acceration. And if your gonna say f1 cars accerate the same as 10k as 19 i am seriously just gonna cancel my registration to this forum.

I am just trying to get the CORRECT information out that is all!

Once again torque isnt the only factor that makes a car accelerate the car.

 

What is the formula for acceleration?

 

L x W x H.

 

Yeah fuck it, its beer thirty. toodles

 

 

i quit.

bucs suck..they need to learn to throw pig skin

 

 

Truck engines are designed to maximize TQ in the lower RPM ranges where it is useful. They dont make alot of high rpm TQ due to camshaft selection and intake design. They require alot of off idle TQ. Doing this ALWAYS will kill the Tq in the upper rpm ranges. Nothing in engine design is free, You are forced to choose one of the other (unless you use a power adder). CHoose to make Tq in lower more strret freindly rpm ranges...or choose a large cam and short runner intake to shift that TQ range into the higher rpm range. This will result in MORE HP...of course..but thats only because you have shifted the TQ range UP in rpm.

If peak acceleration takes place at peak TQ in a given gear (as you have conceeded) then you are obviously understanding that the acceleration rate is affected by the TQ applied. If the motor makes 300 ft/lbs from 3000-4000 its going to accelerate at X rate. If It makes 350 ft/lbs from 4000-5000...it will accelerate a little quicker during that point. If Tq begins drop off...and it now makes 275 ft/lbs from 5000-6000...it will accelerate noticably slower. And lest say for arguement sake....our engine has a funky curve and then TQ come back up to 350 ft/lbs from 6000-7000 rpm...guess what...it will accelerate at exactly the same rate as it did from 4000-5000..even though we are operating in the higher rpms (discounting wind resistance and friction of course).
If you want to know the work done at any given RPM point...just do the math and it will spit out the resulting HP figure. The HP figure is overused and misunderstood.

 

how long did it take you to write that?

i seriously quit...you win hybrid congrats

 

hahahaha, some people just make this shit up.

Why wont anyone listen to the guy with the 9 second street car????

im sure he know something about getting a car to accelerate.




heres what meriamwebster says about torque

Main Entry: 2torque
Function: noun
Etymology: Latin torquEre to twist
1 : a force that produces or tends to produce rotation or torsion <an automobile engine delivers torque to the drive shaft>; also : a measure of the effectiveness of such a force that consists of the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation
