Need some info on oil coolers whats the best one to buy?

 

Would depend on why you want it or need it

2.0L 2.5l?

250 bhp or 600hp?

Long high speed runs?

Trackdays?

What temp does your oil get to?

Precautionary because of high power Mods?

Sorry not having a Pop at you, but a little background info about the engine and it's use etc might help on peeps to chose what's best

IMHO

I've got a Scoobyclinic one for trackday use on 330bhp blob STi. Road oil temps run between 80c and 90c, track oil temp tops out at 105c. Package price was £450+vat fitted.

 

Gearbox or engine oil cooler??

 

Are those the temps after fitting?

As those are pretty much what i see without a cooler. 85-95 standard running and the peak measure on the defi's is 105.

What benefits are there with an oil cooler? Know very little about them, apart from a certain few jap models have them.

 

Yes engine oil temps after fitting, don't have the before as I had temp gauge fitted same time as cooler. Soaring (ie track) oil temps will eventually kill engine suddenly when oil film fails. I have a mate with an 06STi without a cooler and is car runs 100c on the road and 115c on track.

AFAIK max acceptable engine oil temp is 120c so he's considering a cooler as well. Gaz, do you track yours as then you'll see temps going up a lot. I wouldn't bother for road use.

 

i dont have an oil cooler but my oil filter is reloacted to behind the drivers headlight.

i get temps of 90-95 with normal to moderate driving, then with some right foot welly get about 95-97

 

Nope, don't track it. Just wander what/where/why and whether it's a useful mod.

(and yes, i've got a few bob i can spend on the car at the mo. )

 

This one does come up now and then and for road use they're not really necessary. Infact they can be detrimental to the health of the engine in two ways..!

Firstly, it'll take even longer for oil to reach optimal temp, if at all, so yo could be gunning it with cold oil..!

Second, every oil change the cooler should also be drained. Otherwise there's going to be a lot of old oil left, which will immediately contaminate the fresh stuff..!

If you're not sure, monitor your oil temps for a while..

I've got a Mocal oil cooler kit in the garage which cost a few hundred quid....I bought it when I upgraded to the 18G but found the oil temps didn't get that high !!

So didn't fit it !!

open to offers LOL

Shaun

 

Thanks, but after jasonius's comments, there's no need. Plus i'm running an 18g

Now i know anyway, good posts & informative.

 

Indeed, another point is people fail to notice there is water to oil cooler fitted anyway as standard - right above the oil filter.

In this climate in the UK, any air to air engine oil cooler should be fitted with a thermostatic device, to ensure it doesn't over-cool the oil. And its only really needed if you run huge BHP and/or rather mechanically unsympathtic when out on trackdays.

Just for info my 18G smashed my gearbox whilst teaching an Audi A4 a lesson in "in gear accelleration"...LOL

Best turbo IMHO

However ...wondering about an MD123 LOL

Shaun

 

So what would be classed as too cold to boot it? And surely the temp gauge wouldn't get the temp wrong so it'd be ok once up to temp on the gauge?

 

I believe Mocal do a thermostatic oil cooler, so only allows oil through the radiator once upto temperature

 

The Scoobyclinic one on my car is thermostatically controlled. Temp rises to 80c much as without a cooler and then the flow through the cooler opens up and pegs the temp around there. Only rises beyond 80 ish when in traffic (no air across cooler) or on track (lots more heat to get rid of).

 

Please tell me people don't fit Engine Oil Coolers on road cars??

 

Holy ****. What happened there. Can PM if you want.

(You're not the only one who's been thinking about MD321's )

 

Why do people quote this? My Spec C takes no longer to come up to temp. Oil coolers can be controlled using a thremostat so there shouldn't really be any issues.

 

Subaru do as standard, there is one on your car as it came out of the factory .

 

Can be being the problem, so do you know how much longer a non thermostatically controlled cooler delays operating temp..?

There's plenty of them about on ebay..!

The oem water-oil cooler actually helps the oil to reach temp too BTW..

 

Shaun(midlife)the way you are going your gonna have to get a bigger garage all these bits that you have lying about I might have to pop round and relive you off some bits....I have a cunning plan...btw where are you getting your methonol from ??

 

Gussy...thanks for the post

I've been lying low since baby Dominic was born so not much has changed with the car or the bits in the garage !!

2 weeks ago I blew my OEM gearbox so the car is with Alyn for some TLC LOL

The methanol came from Roger Clark Motorsport but the label on the container says "Jennychem"

Cheers

Shaun

 

Blimey !!

I'd forgotten how much this kit costs..eeeek !!

I bought my Oil cooler kit from Jamie Whitworth when he ran JW racing....

J W Racing

Better go and check that it's still in the garage and not been thrown out !!

Shaun

I know I've been lookung for a cheap one but no such thing as good and cheap

Wasn't it Jamie Whitfield

I'll dig out the cooler from the garage tonight and have a look...

You are spot on it's Jamie Whitfield

Shaun

I've taken a few pics of the oil cooler I have....

PM me your e-mail and I'll send them over
