You need torque!

[2strokespirit]

But now you are taking it to far, trying to say about how the bike is set up etc. Anyway, let me put it this way, like you said the amounnt of torque on the rear wheels is not the amount of torque on a dyno,true, so if the seup is the same, gearing etc, 2 motors with the same HP, but the one has more torque than the other... The 1 wich has the torque advantage on the crank wil have the torque advantage on the rear wheels. I know that a 5hp briggs & Stratton go kart can have 200nm of torque at the rear wheels, without having a big engine. But if youu have a torque motor, you WILL have a torque advantage at the rear wheels over another bike with the same setup that does not have that much torque even if it has the same HP. Torque is meaningless by itself, if you read the first post, I said you need a good COMBINATION.

Dont get me wrong here, i love 2 Strokes and they TORQUE with a good setup!

:-)

Its diffucult trying to explain something i want to, because i am not english speaking.

 

I know this has nothing to do with bikes, but same theory. A truck with a diesel engine that has 1000nm of torque and 500Hp will keep uphill, against strong headwinds, thick sand etc pulling a load much better, than a 600Hp truck with 750nm. Maybe you get me wrong, Hp gives good acceleration, but maintaning speeds against hills and sand you need torque.

Lets leave it there, really dont want to argue.

Torque is not just about gear ratios and chaniging sprockets.

[csrmel]

torque has alot to do with ratios of sprockets. if you put a 2:1 reduction on a 60ftlb motor, you have 120ftlb. (ignoring losses in the reduction) yet the horsepower stays the same.

I think somthing is missing. RPM'S ... Torque x rpm / 5252 = horsepower or Horsepower x 5252 / rpm = torque Wouldn't a motor with the same torque with more RPM's have more power at the crank? So in theory a motor making 500 ft/lbs @5000 will not have as much HP as a motor making 500 ft/lbs @10000 RPMs. My diesel make 600 ft/lbs or torque while my camaro does about 300 ft/lbs... why is the camaro faster? RPM'S! my .02

Right, with the same setup.

(I'll use lb ft here for my own simplicity sake, but the results give the same idea).

Your first truck makes its 1000 lb ft and 500hp at 2626 rpm. The second truck makes its 750 lb ft and 600 hp at 4201 rpm. The second truck simply downshifts a gear, and will hold that hill just as well as the first one at the same ground speed. Because that truck has to downshift it makes us think that it has to work harder, and doesn't have as much power, but thats not the case.

 

Im not trying to be an ass, just playing devils advocate. The whole torque is king idea has been around over here forever, and in the drag racing seen all the guys with these huge big block drag racers thought the import tuners were wasting their time. Yet those guys with 4 cylinders are in the 7's in the 1/4 mile now. Torque is the easy way to be fast, and people didn't want to believe you could do it any other way.

 

And your english is great, better than half the people on here who speak it as their only language.

Thanks

I appriciate the language thing.

I know you dont want to be an ass. :-) its interresting, remember that if the truck with the less torque have to shift down, it will loose speed, if the ratio the truck is in, is to slow, so the other truck wil outrun him. :-)

Hey I like you Banshee people!

2 Strokes Will rule as long as the banshees exists, we wil find a way to beat the fourstrokes to come in the next 10 years!!!

You can modify torque with gears.
HP is how fast torque is comming.

This is a good explaination:

It's too bad that he doesn't really know what he's mumbling about.

Teach us. That will be fun. Go ahead.
