jippy,
first me no master
second most replies sounds ridiculous......
i'll share some info, not much, but some
first, the engine temp will reach a certain optimum temperature, normally 80-90 C
then if it was designed to run at this optimum temp, why would anyone try to change its design?- reason cooler is better......or maybe .....yeah i got a cool engine!!
second, chemical breakdown of the molecules when changed of phase from a high viscosity/low viscosity etc,etc
lets say optimum temp is 90 C then when installing an oil cooler say it coolers down to 70 C, then it will then run back into the engine and up it goes back to 90, then back into cooler
yes, in a way, it cools down the engine block, say about 10 C, but it will always be heated up due to the engine design back up to 90
now lets say the thermostat opening temp is at 100, for track cars , it makes sense with the high revs, and abuse, but on a road car? yes it does sometimes, but how often will the oil get cooled down, plus there's one more part that will breakdown, when it does breakdown, there will be a loss in engine oil pressure, when you loose engine oil pressure, oil wont be pumped up to lube the valvetrain...guess what happens after that
back to the topic, cooling and heating up the engine oil will decrease its life expectancy
not running the oil at its operating temp, will not get it to its optimum viscosity.....
julian,
the LSD oil does thin down to a certain extent, due to high temp, this in turn will make it less viscose, in turn you don't want a thin oil inside the LSD clutches at sharp turn corners, your LSD clutch will lockup, sending your rear straight, while the front turns..........well you are the go-kart master, so i need not say more.......
