Hi Guys,
Upon our descent of
Billy Goat Bluff track from
the pinnacles on the weekend it was advised that the first 700 metres required extra caution.This section was pretty chopped up with loads of rocks,steep and quite loose.Apart from low first it was also advised to run the air con to further assist engine braking.I had it on anyway but does anybody know if this actually does assist in severe down
hill descents.
Thanks Mark

Mark,
If you think that it is rough coming down, try going up.
I was there a few weeks ago and some of the petrol vehicles in the convey had to turn the air con off just to make sure that they did not stall or lose power.
Years ago when the idle up on the air con was not an option we use to run the air con on petrol vehicles and even run with high beam and
driving lights on just to try and slow the vehicle. It did help but with the gearing being high, even in low range, first gear, the vehicle still felt that it was racing down
hill.
Nothing beats a big 6cyl diesel with a manual Toyota gear box for going down hills slow.

Drove up Billy Goat on Sunday. Bit more chopped up than usual.
Certainly wouldn't recommend running air con going up or down. Sort of seperating yourself from nature with the windows up as
well.

On a certain level I can understand the theory but on another level I don't.
If I use my TD Troopy as an example it'd actually go down the
hill faster with the air conditioning on.
The reason for that is the idle up solenoid mentioned by a couple of people above.
As Wayne has mentioned, the best way to go down a
hill real slow is with a big diesel six, low range and a manual gearbox.
I guess it depends on the age and the configuration of the vehicle.
