5th is one:one & 6th is an over-drive

Just thinking out loud...

On the strip, would a 5 ot 6 speed box be any improvemnt over a 4 speed? More gear changes means more time of the throttle and less time in each gear

No the JKD five speed is 4kg heavier than the KAD 5 speed and being an overdriven box consumes more power than a 1:1
The JKD six speed would be heavier still!

John Haston was running 12 second quarters using just 3 gears at the weekend! That's also with a cammy 16v engine, although very lightweight.

4 gears is plenty, particularly with a turbo.

That was my thinking. We have a very short first in the van, so we are dropping into 4th near the end of the strip. A longer first may mean that we can stay in third and gain an extra 10th or two by not letting of to change gear

I think the main bug bear on the van is the 60ft times as you have to snag 2nd after about 30ft!

If something is worth doing, it's worth doing half of.

Wouldn't you need a longer final drive for that?

We have a 3.1 in there already. It's the helical box which has a short 1st in it.

An SC gearset would sort that out.

I like how there are a few that think that these things are easy *laughing*

at least some of us realise how difficult these things really are.That is not to say that it cannot be done, but its not just a matter of fitting a gearset from a bike into a mini gearbox. I am still wondering how this sliding reverse gear will be engaged, not to mention where this sliding gear has come from. Again this is not to say that it cannot be done, but its not exactly a 'simple' fit is it?.

Besides that, as others have said, is there any real need for more than four gears. top fuel drag cars only have three gears, and the common six speed transmissions on modern cars are mainly on the narrow torque band deisels.

So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...

or high revving v8 motors such as the audi rs4 and the v10 m5 has a stupid 7 speed box.

is drag racing the only application for a non standard gearbox? wouldn't more than 4 gears be useful on a circuit?

same principle as drag racing - you want to get up to speed and slow down as quickly as possibly. more gears won't really help that imo

I really depends on the torque curve of the engine in question.

If you have a really peaky N/A motor, then lots of close gears is the way to go. If you're got a turbo motor with a nice spread of torque, then you don't need it so much.

It also depends on what your required top speed is. Many modern cars with 6 (or more) speed boxes, have very high top speeds, for this you need more gears to be able to pull high top speeds, and also be able to have reasonable acceleration low down.

Too many projects!

id say more gears is better for a circuit, as you can choose a gear thats going to pull you out of the apex of any corner the longest. on drag gear changes are waisting time. i only use 3 gears in total (2 changes) aswell.

1st to provide proof of a running Bimmy Conversion!

Brisbane ,Australia

Our`s was made by KG-Engineering here in Aust (now folded)

Very good for circuit work, but you`d want "BIG" grunt as the huge gear train & extra large/long motha-fukn shafts & all the extra "oil-pumping" characteristics caused by the 5-million gears in there all tend to suck the power,,, so, not so good for small Hp donks at all

The first 6-speed doggy we got (about 12-years ago) we busted 5th & 6th gears in half on the very first run,,,, we then re-designed & re-manufactured & all was well

this one we have now was also a pain in the butt for a while, as the reverse gear lever "Pin" broke & of course it`s the very last thing to remove from the box,,, it broke twice *frown* then we finally sorted that & it`s all good again

about 6 hours work each time,,, not counting remove & refit engine

*frown*

It sits under a 1600cc mini engine with Arden x-flow,,,, it`s fun but not the fastest mini in the world,,, Very Torquey
tho

a smaller/lighter gear kit, with 1:1 5th & over-driven 6th (like ours except lighter) would be just sweet,,, if it can be made to be repaired easier than ours, would also be a bonus,,, if it were cheaper than ours would be a double bonus ($10K)

I always wondered how much stuweys 6 speed was worth, but never had the balls to ask lol.
