you can't have a tank slapper in a car

[stevepeanut]

reading this months classic ford, the 18 year old lad with the red mk1 mentions crashing it after a tank slapper. I've heard a few people mention tank slappers in cars. How can you have a tank slapper in a car?

 

A tank slapper is on a bike, where the bars go from lock to lock "slapping" the tank... like this...

That looked like it hurt

is it not a case of trying to drift and the car flicking right round the other way after you oversteer to correct it?

 

ie you turn the wheel left while you floor it then you correct by steering right then the car grips and you shit and steer left again......and repeat untill you hit a wall

I think thats what they refer to when they say a tankslap in a car, but I think its usually called fish-tailing

i call it a fook up

i dont think a car driver would ever mean "tank slapper" literally

[OldskoolSue]

I bet that did hurt poor man!

tank slapping in a car is when you have a car like a capri with a billion liter fuel tank which is 3/4 full (or half full) thats a good 20-30kg of weight sloshing around over the rear axle...

 

now... go round a right hand corner (all the fuel sloshes to the tank on the left...)

 

now. turn left and the fuel will slosh to the other side of the tank, once the 20-30kg of fuel hits the opposite side of the tank it causes a conciderable force, which could un-settle the rear wheels, causing oversteer...

so, you correct it, fuel sloshes to other side, causing oversteer the other way, etc etc etc until you hit something or you miss natural resonance and you re-gain control.

 

thats why race cars have foam filled fuel tanks, to stop the movement of fuel (well.. slow it down conciderably!)

i had a beautiful fishtail today with a mk2 golf gti behind me....

 

lets just say he ended up in front of my car but i was still in front of him

Is that why the foam. Always wondered that.

I agree, a tank slapper on a motor bike is a violent thing, and not due to driver error or shifting fuel etc. That's why some 'bokes have steering dampers, to reduce the effect if the 'bike tries to buck you off.
