hey folks just had my md321t fitted with all the supporting mods

now when im normal driving and sometimes giving it the boot the oil temp does go quite high about 96 - 98

when i had the vf35 i never saw above 92

should this be causing me concern

cheers

steve

No.

110+ is when you should start to think about a cooler, 120+ is max i think before it needs to be fitted, think 150c is when oil becomes into dangerous temps

cool cheers folks

better be safe n invest in an oil cooler since you upgraded an turbo. My buttom end bearing went on my v3 after i fitted a hks GT2835 and given it after hard driving the bottom end went. i think this is due to the excessive heat generated and load of the turbo.

Splitpin

No, better to leave it alone if his oil temps aren't even into three figures. Scheize.

Under these circumstances "investing" in an oil cooler is probably more likely to increase the chance of an engine failure rather than the opposite.

The difference between 96 and 92 degrees celsius is probably more likely explained by higher ambient air temperatures over the last few weeks than the turbo change.

What evidence do you have to suggest that unduly high oil temps were a contributor to your engine failure? Were you actually running a gauge at the time, and if so, what readings were you seeing?

Is it possible that your engine was already somewhat weakened and your new turbo (and the hard driving you presumably subjected it to) simply pushed it beyond the point of endurance?

I understand you're posting with good intentions here but suggesting to the OP that he fit an oil cooler under the specific circumstances he has reported is likely to do more harm than good.

pooeater

more sound advice from splitpin im led to believe oil only starts offering its full protection at 100 degree?

Don't worry till you reach 120 degrees.... I did add an oil cooler to mine, but it has been know to suffer some track(ab)use !

I see from your other posts that you have also fitted a front mount, this will probably be contributing towards the increased oil temps as it sits in front of the radiator which in turn cools the modine. As others have said the temps you are now running are nothing to worry about.

Mine made no difference to the water temps.

It hasn't moved since I bought it 8 years ago....

cool cheers folks i havent nailed it properly yet but i will defo resurrect this thread to update the temps

from checking on my buttom end the piston/rods are all in good shape. only the main bearing did have a problem and slight damage on the crank. I am thinking that this could be cause by increase in engine oil temp as i have no problem before running this si a front mount intercooler

What were your typical oil temps and pressures before and after the turbo swap

Splitpin

As per Butty's question...? If you're thinking that the failure was caused by an (unsustainable) increase in oil temp presumably you're running a gauge?

right guys thread resurrect was at knockhill earlier this month and seen near enough 110 on the oil temp

should this cause me concern

On track? I'd have thought not.

iTrader: (13)

no

130+ then yes,time to rethink the plumbing/cooling of the oil

RA Dunk

You should be safe enough at that, I tend to run as high as 120 at Knockhill but usually stop for a while and let it cool when I reach just over it.

You will be fine at 110 on GOOD oil.

Not fine on sh1te oil



Millers CFS 10/50 or 10/60 or Motul 300V 15/50 is what i would suggest for you Steve knowing your set up.

STI Glenn

My car only a remap oil temp 85 ,my old Spec c the same .

Both cars standard oil coolers

cool cheers for your replies guys

the motul is going in this weekend

ready for KH in july

my bottomend just went clank while i was idling on the road for 10 mins. before this happen i was just giving it some boost reving till about 5k rpm which is not really pulling redline and at insane speed as i was just breaking in the new turbo

Tidgy

im not sure where you all getting these figures from? i saw 105 and backed off peaked at 110. oilcooler was fitted straight after.

didn't zen fry there full race spec engine when it hit 130 degrees at coombe a few years back?

perosnal if i saw tripple figures without a cooler one would be going on.

Splitpin

Yes, and? You were repeatedly asked if you have any direct evidence to suggest that unworkably high oil temperatures were a causal factor in your engine failure. Have you actually got any? Reading the above, there's nothing to suggest this was the case.

So what was it about those numbers that convinced you that an oil cooler was a must-fit item? My figures tend to come from lubrication datasheets or the advice of people with more experience.

Not sure what that has to do with this thread. If you are trying to turn a one-off anecdotal story about the failure of a highly tuned and very non-standard race engine into a sweeping generalisation, that would probably be a mistake. In any case was the failure directly caused by the oil temp hitting 130, then, or was that a coincidental/contributory factor?

Well, clearly, and ultimately what you do with your own car's entirely up to you. What isn't clear is exactly why "triple figures" seems to be such a big thing for you. Where are you getting these figures from?

i saw 100 degrees just normal driving, since oil boils at 140/150 i think 130 below is the point to be thinking about coolers

100/110/120 as long as it doesnt stay at this,so on the straight it drops a smidge,o.k

my 100 round town soon dropped to 90 once i was above 40 mph

Sc0oby

oil temp is around 100
