i have no clue were to post this, but i figure this would be the best spot. k i wanna make a vid this weekend and get some donuts in it. my question is what the best why to do it, i want smoke!lol. do i just go from a full stop turn the wheels all almos to the end and slam the gas? do i just creep forword and turn wheel and then slam gas? bring up the rpm the brun forword and turn wheel? how much do i turn the wheel? i dont wanna brake my car. thanks people

 

hold the brakes on and rev up the gas and make the tires scream. install a line lock. try and push a big dodge in a parking lot. i have no idea, ive never done a smoke show. we'll see if this gets locked

 

ok, in second or first (try a couple of times and get it so you like it) gear go prety fast in a circle, once youe are at about 2.5k floor it and do a clutch kick, for the un-informed a clutch kick, is a drifting technique used to upset rear traction. all you do is uickly push in the clutch, and drop it again, in the brief fractions of a second your clutch is in, your rpms will shoot up just enough to spin the tires once you drop it back in. this is the only good way i can do cookies in my v6, you v8 guys probably just turn and hit the gas, anyway, i hope this works out

 

If you have a large enough parking lot without any barriers in the way (light poles, curbs, pedestrians, other cars, etc) you could always try a J-turn.

Remember that with an open rear, when you're doing a burnout, since only one tire spins, that tire's going twice as fast as the speedometer says. Example; you're peeling out and the speedo says 30 mph- the tire's really doing 60 mph. Don't blow anything.

And you might not want to start a burnout with the tires turned to the side!

 

why is it the speedo is half of what it really is with an open rear end? the speed sensor is at the tranny, i dont see how spinning 1 or 2 tires would make a difference? its also inrelavent because the car isnt actually moving anywhere so its 0

no really i want to know why that is...

 

just some screen test shots for a film im making, but heres some burnouts:

technique... if you have a auto... hold the brakes enough that you dont move, and mash the gas. with a manual.... rev it up while holding the brake and dump the clutch.


also for cheap thrill... go about 15-20 mph.... have your left hand over the top of the wheel and on the right side... so that you can yank it to the left quickly. put your hand on the ebrake. in one quick motion, pull the ebrake until you are at roughly 90* of where you once were... at the same time, yank the wheel to the left and mash the gas. the rear first slides because its locked, and by the time the emergency brake is off the engine is up to RPM and spins the tire.....keeping it sliding....




another thing... for a smoke show put bleach or oil on the tires..... BUT because you have a posi, only one is going to spin..... whatever one you put the stuff on is the one that will spin... normally the pass side spins.



another thing, if making a right turn, you can over turn, mash the gas and if you were going slow enough, it steps the rear out in the turn and you can "correct" to the left....



keep in mind alot of this will look stupid if you have a L03 and a open rear....... unless you cant see that only one wheel is spinning .............

 

simple.

hes wrong.

the tire is going the same as it would otherwise.

 

no he is correct, on an open rear , when 1 tires is spinning it spins at twice the speed that the sensor will be reading.

obviously you have never looked inside an open rear end. the side gears are only half the size of the ring gear, so when only one side of the open rear is spinning, it spins twice as fast.

 

mmk, correct me if im wrong... im trying to visualize in my head late at night..

pinion turns the ring gear.... ring gear turns the open carrier with the spider gears in it..

holding the drivers side wheel still, the ring gear turns the carrier with the spider gears in it and that carrier is attached to the spider gears and that turns the axles........

now normally the spider gears wouldnt turn... the whole assembly turns as a hole... but now the spider gears are turning to deliver the power..... but....


its all spinning the same speed still



what do you see in there that would change the speed? all the gears in the open diff are the same size.

 

like i said, go crack open an open rear, and turn it.

you pretty much have it right...

BUT

the spider gears are half the size of the ring, so they turn twice for every ring gear rotation.

we just had this argument at a local camaro club gathering not to long ago, and the agument ended with us opening up an open rear, and turning 1 axle trust me, it goes twice as fast.

 

but, uuh, doesnt the ring gear size change when you change gears?

 

only in realation to the pinion gear, doesn't change the ratio as it effects the side gear. the ring gear only determains how fast the carrier turns in relation to the driveshaft.

1 rotation of the carier = 2 rotations of the side gear.

 

mmmk..... wierd...


i think im just going to stick to lockers.....

and come late night, im just going to pretend they're all spools..... easier to imagine.
