BEC Oil temps
Good morning,
As the Sun was out, I thought it would be rude not to take out the Fury on the chilly weekend we just had
Just a few questions really, After a warm up and about 30mins of steady driving the oil temps never exceeded 48/50c. Is this normal? I am completely
new to BEC and their characteristics
Bit hesitant to give it the beans at 50c.. Or am I being too over careful?
Oil is Castrol Power 1 using the standard R1 5PW oil/water cooler
VW Polo rad
Regards
Chris

With the oil-water cooler it should act to heat the oil as the water temp comes up. I'd expect it to be close to water temp after 30mins. What
was the water temp reading?

Half an hour of running should get water temps up. Think the stat opend at 70-75ish and mine (5vy) gets there in 10-15 min, even just ticking over.
I'd check the stat isn't stuck open, resulting in it over cooling with the large (compared to bike) rad' and low ambient temp.

Good shout, will take a look tonight
Would would be the "Best" operating tempriture for the oil to be at before giving it some abuse?

I find it's a bit of a chicken and egg situation. Don't thrash until the oil temp comes up but the temp doesn't really come up
untill you thrash it. I'm running a seperate oil cooler which does make that worse. With the standard one I'd say on the road, once the
water temp is up you're good to go. For track use I was advised (by a BSB engine builder/mech) warm it up gently untill the fan kicks in
(standard is 105deg) then switch off and let it heat soak 10mins, then repeat and go.

Is the sender mounted remotely? If so, it will read cool.
My oil temp sender is mounted with the pressure sender on the end of a ~30cm braided hose to isolate it from engine vibrations. It always reads really
low because it's effectively a dead end for the oil and only heats up through heat soak. I need to relocate it to the sump really.

To get oil temp up you need more water temp, when i was racing i put some duct tape across water rad when ambient temp was low.

An oil temp sender should never be positioned in a dead end position!
As above if it is it will never read correctly,needs to be in the sump or with oil flowing over it.
Mines in the end of the oil modine fixing bolt and reads accurately

Cheers for the replies
My temp sensor is mounted on the sump
Will check the stat tonight and see if it's stuck open. We got the engine bloody hot during the IVA dramas so it may be stuck open

I'm aware of that hence saying it needs moving from where the original builder located it.
