Gearbox ratio

[SLEEPY]

Does anyone know how to work out the ratio in a gearbox. Is it a case of jacking up the back end putting into each gear, rotating the crank 1 full turn & seeing how many times the prop goes round or is there another way of doing it.

Someone here should have the info you need m8. What box is it?

[SLEEPY]

it's a type 9 with straight cut quaife internals, which I bought a few years back and I can't remember the ratios

[over_head_cam]

Ah. That would be difficult then

[bortaf]

If it's still on the car basicly yes that's thhe only way to check

tippex is your friend

Counting is easy till you try to decide if the last bit is .6 or .8 of a turn Would quaife not have any info? might be worth the cost of a phone call.

If I work it out using tipex and turn the crank I should be able to work out the gearing using the info on the link
