G-Gear

Postby kevinthesyncro » 30 Apr 2018, 23:27

Hi all,

My question, when using G-gear what is the best method, ie how many revs to get out of trouble, how much gas pedal etc, I know its an ultra low gear hence the question regarding revs??????

Cheers

I havn't got a rev counter but i've never felt the engine needed to rev its nuts off when trying to get out of trouble.

If you are going up a steep incline and you feel you need to change up - change up. If changing up means you will lose revs, stay in G but back off a bit and take your time.

Using G for engine braking on a slope - it can rev high then but very gentle braking to assist will help.

I'd second what Jim San said, just enough - and out of sympathy for the gearbox and the rest of the drive train, gently on and off throttle as well. :D

"drive as slowly as possible and as quickly as you have to"

Or somethng to that effect.

I understand that use of sustained high rpm in G gear on a worn/unknown transmission can lead to expensive repairs.

Great stuff guys, thank you!
pretty much how I was thinking, I have had moments in soft sand but still managed to self rescue but never used G-Gear for some reason (never had to) but now in retrospect I cant believe I didn't use it, hence my original question. I do believe if I had used G-Gear and let the engine "pull me out" I would have got off the beach a lot easier???

Cheers all.

Syncros in sand is a special case!

(decoupler & solid shaft vs VC argument usually ensues at this point)

we've all done it (we won't all admit it - some of us will deny it lol) . I drove the German trial at BusFest - did really badly - got to the end and remembered I had a G-gear. :rofl

:oops:

It's all good fun.

Excellent points above - easy on and off the gas, be kind.

Once you've got caught in soft sand its best to use your brains straight away. You may be lucky and drive out but its so easy to dig in - try twice but as soon as you feel spin, stop.
Give the tyres some grip, mats, boards etc. quicker to deploy them now rather than a whole load of digging.

With a healthy 1.6 TD you get max torque around 2500 rpm (approx 138Nm), so that would be a sensible target maximum, as beyond this there would be no real benefit in terms of power. I don't know what engine you have but a similar approach for other types would probably be sensible.

I came across this in the wiki a few days ago. Seriously impressed by the syncros hill climbing abilities. :ok

I assume the G-gear is a significant contributer here

The notes say those figures are for 1st-gear so you'd expect G-gear to maybe be slightly better?
