Wheelspins...

[karthik247]

Hey guys,
Doing wheelspins in 1st gear is pretty much easy..but could someone shed some light on doing them in 2nd gear or even 3rd??!!

Drifter, need help here

Revv the engine to the redline and dump the clutch. You'l get wheelspin....provided your drivetrain survives.

i tried that..after a very very small wheelspin, the car got off :(

That's bcoz the higher gears transfer less torque to the wheels compared to the 1st one.

You'll need massive amount of torque or least amount of tyre grip, to spin the wheels in 2nd and 3rd for a longer time.

Next time, try it on a slushy surface, you'l spin the wheels for a longer time.

i didn't that on gravel..Anway whats the real difference between 1st and 2nd gear wheelspins??

The diff in torque transfered, depends on the gear ratios (final drive ratio being common for both).

In simple, it's your torque figure multiplied by the gear ratio and final drive ratio. If a car produces peak torque of 200nm at 4000 rpm and the 1st gear has a 3.4:1 ratio with your final drive being 4:1.

At 4000rpm in 1st gear, the torque reaching the wheels should technically be 200 * 4 * 3.4 = 2720nm but, it usually ends up being a bit less due to loss of power through mechanical friction.

So, if you have to achieve the same result in 2nd gear with a ratio of 2.5:1. the engine will have to produce 272nm at the crank (which isn't possible as the engine torque peaks out at 200nm).

What results you achieve in 1st gear can never be matched by the others.

Why would you want to do a wheelspin in 2nd or 3rd gear. Who are you trying to impress.

Just wanted to know how its done and whats the difference..Anyways i think i'll stick to 1st gear wheelspins right now

[revtech]

its done the same way only thing is you have to rev a lot more before you leave the clucth.how long do your first gear wheelspins normally last.i mean how many seconds.

Guys is it possible to change gears just when we see that the wheelspin in the 1st cant be held any longer.. For eg. while doing a burnout on a bike we can use half clutch to move to second gear n continue. Hell we can even drop the gear without the clutch. Anything possible for cars ??!!??

I definitely wouldn't wanna buy cars from karthik247 or bikes from The Don.
Its definitely not worth doing wheelspins on stock cars guys.

why not whats soo bad in it ??

1. Slipping clutch
2. Wornout tyres
3. Damaged driveshaft
4. Reduced engine life

hey shan2nu could you please elaborate on that as this is an interesting topic.firstly what do the terms slipping clucth and damaged drive shaft mean.

firstly what do the terms slipping clucth and damaged drive shaft mean.

A clutch is said to be slipping when it loses it's abiltity to lock onto the flywheel, without friction.

Driveshafts can get damaged if they are subject to sudden jolts of turning force (torque). It's ok if the wheels start spinning easily but, if they don't you could damage them. Even if they don't get damaged, they will encouter "Play" in the long run.

Tyres are bound to get worn out due to the friction caused when they're scraped against the road surface.

Engine life is reduced as it has to revv close to the redline without the required cooling aid. When a engine is revved with the car in motion, the air hitting the radiator helps cool the engine but, in this case, the car is basically stationary. All the cooling comes from the radiator fan (which isn't sufficient).
