Just a observation:
With my tune, coolant temps are now a reasonable 175f
I've noticed that my oil pressure is now some 8 psi HIGHER at idle as the oil is not reduced to thin brown runny water. What a wonderful feeling (being an ex machinist) knowing that my poor little abused motor is getting some relief from it's grueling existence.

 

Nice! So Manic was able to modify the coolant temps for you without a problem?

 

Hope you're taking nice long drives. With the lower coolant temps, the oil temp is
also lower and not readily getting up to the point where accumulated moisture is driven off.

 

Yup...you can rust your motor to heck with moisture in your oil....water is very bad lube....
Motor oils are made to work at fairly high temps...and syenthic oils (required) are great stuff ....if you are worried about higher oil temps making your oil too thin....try a 0w-40, like mobil1 euro spec...meets bmw /mini specs.....but remember, I would not go thicker..machining tolerances are tighter than in years past...and oil that is too thick can be bad...

 

I love the nasty nay sayers. I wonder why they bother with such statements. I feel folks should state their profession and experience prior to making statements
I spent 35 years in the automotive repair biz incl rebuilding and modifying german engines.
The only reason cars run so hot now is emissions; that's it!!
Engines ran at 175 for a century with no adverse effects
water is always evaporating in any running engine as oil temps risw above 212 almost immediatley at slower speeds and especially idle. Overly thin oil is not a good lubricator especially in a turbo motor. I'll take my setup any day over 220f
BTW why do BMW/Mini engineers lower coolant temps to 180f under spirited driving?
Now run along.

 

My previous car, which had an oil temp and a coolant temp gauge
indicated otherwise. After a while, the oil temp would equilibrate to
about 10-20 above the coolant temp, but the coolant would get up to
operating temps before the oil would.

My point is that coolant temps lower than 180-190 are going to have
similar effects on the oil as lots of short trips, and some of the water
and other volitile products of combustion can get into the oil faster than they
get out, especially if you have both low oil temps and short trips.

 

N14? only reason I ask is because oil pressure is controlled by DME on N18 cars so was wondering if Nick was messing with those parameters also.

 

Noticed the exact same thing in my corvette. When I had my fan switch adjusted down from 220 to 190.

With that said, I don't have any prior experience with doing this on a turbo car. Maybe n/a is different in that regard.

Op/ thoughts on the differences between n/a and turbo?
