Hi Shane.
No I dont. I have the chain driven R15 box that has the lower ratio.
To show the difference Gears make here is a video clip of the steep slippery bank on the No 6 track at Westport.Very few trucks drive this. Out of the 3 last trips only 2 trucks have made it. A couple of trucks have slipped back and rolled here.
The 1st attempt I have is on 33s and 2nd gear, but miles too much power and not enough momentum.
Andi Delis then drives it in the 3.9 V8. I then change up to 3rd and get up but have no power left to shut off if needed.
The 3rd time I am on 35s and 2 gear and with this setup still have heaps of power but also momentum.
Chris Hollis trys in a 4.2 landcruiser with lockers but only gets about a 3rd of the way up.

Cheers Richard
PS Next time Jafa is down we will have show him this track
