oil coolers

[k77-widow maker]

what are people's opinions on oil coolers, is it a worth while option, or a possible waste of time?

Only in mine, the oil pressure drops a lot when it's warm, which can't be good for the engine surely???

i reckon theyre a good thing,especially on a pre-serp like yours.in the summer itll be a great improvement.the above only applies if you fit a thermostatic type though imho,no stat= overcooling in some circumstances .

[Guillotine]

anything above 6psi hot is ok...

oil coolers ok if you can find somewhere to put it that doesn't bugger airflow further!!!

a variable pressure regulator is easier, don't set it too high (main bearings mines set at about 15 low vhot)

cheers

oil coolers still a good idea though

The usual fix is to put thicker oil in, eg 15/50 or 10/60.

I've got an oil/air cooler for sustained track use, an oil stat is essential as somebody else mentioned. An alternative well worth considering is an oil/water cooler. The two big advantages are that it reduces the warm-up time (oil is a lot slower to heat up than water, and you really *don't* want to work the engine hard until the oil is up to temperature) plus it won't over-cool the oil. Only problem is if your cooling system is already marginal, you may find the oil cooler boils and then you're in trouble. Should be OK if you cooling system is in good order though.

I seriusly recomend you fit an oil temp gauge, like v8s said more damage is caused by oil being too cold than too hot for the majority of oils the recomended temperature is around 180/200f

V8 Racing, do you recomend a coler for mine, i never had one on the 3.9 but the problem with mine is the room,when engine is built and in, i'll show you the car and u will c what i mean

Hi demo again it really does depend on the temperature the engine runs at?? i had a 3.9 racer that i was running a standard sd1 sump on the engine produced 340 bhp but on my 4.7 producing 44o bhp running a big winged grp 1 sump i struggled to get any temperture into it so i never ran one it realy boils down to the set up you have in your car and lets be fair the dosh you have tied up in a motor whats £30 for an oil temp gauge??

[demo2]

I have an sd1 sump, which i have copied the swage in it to clear the crank, i will baffle it as well. Like you say, an oil temp gauge would be the way to go.

[v8 racing]

Hi mate if you are runing an sd1 sump i can guarantee you will need an oil cooler, is there not enough room for a range rover sump at all??

[demo2]

no fraid not, i have 5mm clearance betwen sump and crossmember!I have 2 drop crossmember down to get the damn engine in!!

Give Mat a call @ Think automotive, they specialise in oil coolers and aeroquip hose, they do a stick on temp strip which records the highest temp reached you put on the oil filter. their number is 02085681172 hope this helps regards James.
