hey, i have a dvx, and i can only get it to come up into a wheelie in first/second gear....does anyone else have the same problem...do you need to use the clutch to get it up in a higher gear, or just try to pull harder and sit back farther?

 

Even guys with raptors have a tough time doing wheelies from 3rd.

 

my understanding is this. torque is what gets you going and when you wheelie you have full use of the quads torque, but the faster you go hp takes over. and you have less torque at higer rpms and more horsepower. so when you are in 3,4,5 its harder. like my car has 375 torque and only 270hp. so i can get great launchs from the line because of the high torque at low rpms. and i can burn the rubber in first gear squak them in sec and sometimes chirp um in third. but the higer rpms im running less torque and more hp. Im not 100% right but i have the concepts and i hope it helps you. I remember it like this Torque is what gets you moving and hp keeps you moving. Im not a mechanic or a car expert, so dont flame.

 

Superballs5337 sums it up pretty good. Torque is the twisting power that the engine makes, and is an actual output of the engine. Horsepower is actually a made up number based on an equation of HP=(TorquexRMP)/5245 or something like that. Don't take this as 100% correct, as it has been a while since my college days, but it should be pretty close. But YES, it is torque that makes you go like crazy from the start. That is why these twin cylinder snowmobiles can beat the triples off the line, but in the long run the triples will run them down. Also think about tractors, the produce only 15-150hp (maybe more for some big new ones) but will out pull a 300+ hp truck anyday.

Wow, my post has NOTHING to do with the origional one from DVX32. Sorry man.

 

yeah catterman has more of the math down. but i guess if u wanted to wheelie in higher gears just pull up and bounch on the back of the seat to pop the front tires would be my guess.

 

You divide by 5252, so yes, you were pretty darn close. [img]i/expressions/face-icon-small-smile.gif[/img]

The reason it's easier in lower gears doesn't have so much to do with the rpm and hp (assuming the torque curve is somewhat flat), but that you lose the torque multiplication of your gears. For example, if an F150 (since I can't find any atv gear ratios on the 'net) has these ratios:

1st 2.84
2nd 1.55
3rd 1.00
4th 0.71

Then if it has say, 200 lb-ft of torque at 3000 rpm, in 3rd gear you get 200*1 = 200 lb-ft to the ground, but in first you get 200*2.84 = 568 lb-ft to the ground. Lot easier to pick up the front with almost three times as much oomph.

Now we just have to wait and see if Corpsie corrects me....

At least that's my theory and I'm stickin' to it. [img]i/expressions/face-icon-small-wink.gif[/img]

 

yes i know how torque and hp works, i dont need the numbers and all that stuff...i was just wondering is it possible to get it up in third or fourth...thats why i asked for DVX owners....i guess z400 or ltz would work too

 

well yes you can, like i said all you would have to do is pull up really hard and slam your @$$ on the back of the seat or hit a bump to help you pop the front end up.

 

After installing all the Z400 Yosh goodies on my DVX it seems to come up in third even when you don't want it too sometimes ! [img]i/expressions/face-icon-small-happy.gif[/img]

In stock form, up in second before the revs were too high was about it.
