Removing prop does it kill the VC ?

Post by **crazydiamond** » 20 Feb 2006, 18:04

You often see peeps advertising vans with prop removed (to save petrol ?) well I got to thinking that surely this helps to kill the VC rather than preserve it, only one side being driven via the diff, so will always be locked up.

Hmmm, ran mine for a while without the prop as it was off for reconn. Interesting thought.

No, because without the prop on there is nothing for the vc to 'lock up' against.

So it just sort of free-wheels does it Sam, I suppose no real temperature rise then?

Geoff - of all the animated gifs in the entire world, that would probably be the last one I would expect you to choose......

Jen, youre probable right about that gif, its all Phil's fault he was playing around and added it to my profile. Its about right though we have cats by the hundreds terrorising the fish in the pond and now twin white kittens from over the wall to add to the terror!! Thinks must get the water pistols working!

Washing up liquid bottles are great for water pistols, and a well aimed stack of flower pots does a good job too, (empty of course) but the cats soon learn not to go near the pond when people are about!

taking the prop off wont harm the vc,but it also makes no difference to fuel economy as the front diff is still turning,cj.

VW actually proved during development that there is an improvement in economy due to the 4WD, Posche have also claimed this in past. But don't think they're comparing 2WD to 4WD but Syncro with prop Vs syncro without prop, about 1.5%- 3% IIRC. Theory goes that the slip losses of drive wheels is reduced as it's spread between all 4, but expect their figures are surface dependent.
