Technical Oil Cooler?

Technical Oil Cooler?

It's a good brand. Looks a little large, so check that it'll fit. Don't forget you need hoses and a thermostatic take off, and make sure you need an oil cooler. Realistically, we're taking turbos and highly tweaked engines.

If I were starting from scratch, I'd fit a water/oil intercooler instead. They're tougher, warm the oil as well as cooling it (tying water and oil temperatures more closely together) you don't need a thermostatic take off, and you can stick them anywhere you can get oil and water to.
 
he's turboing it.

my engine, even when playing on the motorway doesnt get hot enough to imo require an oil cooler. suspect its different with a turbo on though.

get your point about the oil/water too. if im sat in traffic, water and oil temps will be around 85-90, drive off and the water temp plumets.
 
The great point about tying the temperatures together is that from cold the water warms up quicker, warms the oil, and thus reduces engine wear. Alfa 155s have them as stock, so I may contact my friendly Alfa breaker...... unlike oil coolers, you can clean them out even after a humungous blow up, so should be safe enough.
 
Bummer. Looks like the Alfa one is actually incorporated into the water radiator. Only the dimmest minds of Fiat and Alfa could have concieved of such a plan. They're not that well made and can corrode externally which means you het oil in the water..............

Volkswagen pinched the idea with the same results. Serves them right.

So, it looks like Laminova or bust!
 
Demon Tweeks do them, GoBe showed me a link to one a few weeks back. Not a bad price tbh.

It's on the cards for mine. I think the bigger engine and lack of space, is getting it a bit warm. I've seen 93-94 when standing after a hard blast. At idle though it's a nice 88 so perhaps a need an earlier opening stat to just give it that extra bit of time.

Yeah Kris' is right, I'm looking to completely change the traditonal arrangement for cooling for various reasons, this means it's simpler to use an oil/water heat exchanger, but may also require a marginally larger rad. Anyway Oil coolers at Demon tweeks.
 
Thanks for the links guys :) looking at them oil/water heat exchangers they don't look bad! I'd probably go for the 245mm one. Should be sufficient shouldnt it?

I'll probably be using a bigger rad anyways, But if using that oil/water H/E would it still be beneficial to use a cooler opening stat :confused:

No need for an oil stat if you're using a water/oil heat exchanger, the water should be somewhere between 80 and 100C most of the time which means the oil will never get much below 95C or so. There is a lot of information on the MOCAL/ThinkAutomotive site about how efficient they are in various configurations.
 
I'd probably think about a larger capacity radiator if you go for a water cooled oil cooler asking the normal cooling system to get rid of even more heat might be a bit more than they can handle giving how marginal they are normally .

another option of course would be to fit a cowel and cooling fan to the back of an air oil cooler, either linked into the normal rad temp sensor or using a seperate one. The only time i ever see the oil temp above 95/100 degrees is when sat in traffic so a fan would do the job there.
 
an air to oil cooler you mean? With the pipes made up to suit? The engine is still in my room at the minute in bits! The head is in the boot of my car awaiting being dropped off for skimming, new stem seals and valves grinding in. You think i should wait until after the turbo engine is fitted in to the abarth cento and then get it all made (pipes etc.) to fit?

Cheers

The standard rad is probably up to coping with a water/oil heat exchanger with the lower temp thermostat and switch Aaron puts on the turbo cars: an MPI Sei rad has bigger area but should fit, although it'd need mods to take the fan switch, I think (fan controlled by ECU on MPI). There are all kinds of tiny sensor heads you can literally put through the gap between hose and radiator nowadays.

But, provided you don't see oil temps over 110, no need to worry. On Blue I saw a max of 115 on a cool evening which was a bit worrying, but may have been a sign of impending doom in retrospect!

I'm still getting mixed messages re the Alfa heat exchanger: some accounts say that it's integral with the rad, others that it fits behind the oil filter, so (as friendly Alfa scrapper is miles away in Daventry) I'll either pop in to nasty Alfa scrapper in Liverpool or to Howard's next time I go to Tweeks.
