thermostat?

its not needed, the oil still heats up very quickly and maintains a constant 100degrees, so perfect, as you want your oil to be between 90-110degrees.

I'd rather it took a little longer to heat up than run about with 145+degrees on the oil as its starts to break down at that heat and then the turbo bearings are going to have a short life.

That means the oil cooler is closed with a cold engine and goes open if it's warmed up.

So the oil is quicker on temperature.

i know i was meaning where is it, if not running with a sandwhich plate with a thermostat in it - then theres no stat..

With a stat on though you'd have best of both, heat up quickly and run at 100degrees. It might be ok temperature wise at the moment, but come winter.. i remember heading to the CC AGM last year at cruising speed Pete's oil temp was dropping more toward 50c because the engine wasn't doing much and the air was cold.

Nah, given choice of no cooler and possibly running 150+degrees and risking oil degradation and turbo failure or a running a cooler with no stat, I know what I would go for.

There is the simple solution of fitting an in line thermostat if it gets to cold!

I build in the sensor in the oilpump instead of the oilcan/carter and the gauge give 115 degrees Celcius at normal highway speed and just over 125 at FT. Is this normal?

In the city it's about 100 degrees.

I can't give you a definite answer, but i use my integrale as a guide and it runs at about 85 normal driving, and about 100-110 when using lots of boost, maybe a bit higher on a track day, my Cinq runs about the same if a little higher.

i think anything above about 130ish is getting a bit too hot.

Latest reply to a thread in history, but im going to a exhaust place today about a turbo back downpipe with decat section and see if they can bring it forward slightly too so i'll have space for sandwich plate... shall see

p.s.

 

[custard]

not an expensive fix over a remote stat/filter?

 

[GhostWKD]

not really as was looking at larger bore downpipe with decat section anyway

Place today quoted me £250 with a slot in/out decat/cat section, yesterday place quoted £120 without the slotted cat/decat so maybe cheaper to get them to do it plus the section
