Has anyone got any info on what the max temp they've seen on their VX220 turbo is please? Info such as ambient temps and level of tune are pertinent too please in order to get a feel for things.

 

Thanks.

Mine usually runs at 83C and I don't usually get above 86C.

 

On the day I bought it, I got stuck in a huge jam on the M4 and it went up to 105C before I bottled it and pulled over.

My stage 4 runs at 86 on the road and track ( whilst moving) that's water temp.

Nev I will try to look in my old info recorded as I did some test pre additional oil cooler fitted on vxr / m32 vx setup stage 4 and then extra bits I did. Seen some scary temps across Europe tracks / traffic and mountain passes etc

Certainly could see above 100deg on track even witj PA rad and cc

People seem to be writing about water temps (as they are so low), I am asking about OIL temps.

I see 130° on track. (turbo 280hp)

Yep sorry, meant to say mine were water temp, dont run an oil temp guage/readout

Thankyou. Anyone else?

I see about 120 degrees on track, 411hp turbo

Curious Nev what sensors location do you use for pressure and temp readings ? Might put some extra guages in if its not too much hassle

I don't actually know, as I don't have an oil temp gauge, hence the question. I've had a nagging doubt about my oil temps from some incidental evidence and was considering an oil cooler.

WOW!

Hope you are running some damn good oil for that

 

 

From memory, and mr Fez will likely correct, MOST engine oil is happy to 110Deg C and the fancier stuff is happy to around 120Deg C before they start to breakdown etc.

 

Some of the quirky issues with Oil temp is where you measure it as most of the time the only place to get a probe in is just past the oil pump, which may or may not be helpful. Granted if that is HOT then you have bigger issues at hand as that means the sump oil is hot and subsequently where its important may well be much hotter.

 

Nev, you could look at expanding the sump capacity to give a bit more thermal inertia

I used to change my oil every 1000 miles previously, now changing it every 1500 miles.

 

As I am likely going to take the clam off soon to replace my worn out gearbox, I was considering sticking an oil cooler in as it would be a good moment.

 

Some of the "incidental" evidence I've noticed on my engine is:

 

1. Requires w50 oil for winter or w60 for summer, or it leaks from a variety of seals.

 

2. Contrary to the presumptive track-day know-it-alls I get the feeling my engine oil sees higher temps than almost any VX220 based on evidence like:

     a) The brittle colour stained stainless steel (304/316) in my exhaust box, highly unusual and indicative of VERY high temps.

     b/ Thick welds failing on the exhaust manifold, probably/at least partly heat induced.

     c) I know how hard I push it at times, and some of the 450 odd KWatts of heat ends up in the oil for sure.

     d) I have oil squirters under the pistons, which can only add to the heat in the oil.

 

3. The oil seems to lose it's viscosity quickly (I've done some DIY viscosity tests), might well be due to petrol soak though.

 

4. Necessity to run without a floor pan or everything overheats (when pushing on).

so are you going to change your current oil cooler for a bigger one or add an additional one?

Wondering if it's worth sticking a 21+ row (air cooled) additional one in the left ear which I've kept empty for 8 years for this sole purpose!

 

Problem is it's extra weight yet again on a 960 Kg car, and extra oil capacity/cost every time I change oil, not to mention the extra cost + effort to install it in the first place.

would it add that much weight? 

 

do some overtime

Guessing 4 Kg of weight + 1 or 2 Kg of extra oil.

 

Ha, any overtime I do isn't paid, they expect it for free!
 

[Ivor]

So where do people take an oil temp reading from?
