I'm basically getting rid of the heat exchanger and going to run a filter relocation setup and have a Laminova cooler in the oil loop so i can get rid of the oil to air coolers, i was just wondering whether anybody else has used a laminova cooler and what you think to them?
What size did you use?

I've done a bit of a search and see that Mike (Cosmic spanner) used one so i've been in touch with him and he seems impressed by it, i think i also saw a few others have bought them but havent seen much feedback about them so thought i'd best ask before i buy one incase i'm as well to just stick with oil-air coolers.
I'm hoping to see upto 300bhp from the engine in the not too distant future so i'll probably be getting a larger custom radiator made up to suit the setup when it all goes in.

Finally, am i right in thinking i just need to order this part 1103.54 to hold the oil take off plate to the block when i remove the current take off and heat exchanger?

Cheers.

Yes that's the correct part I believe. Should be thread locked in place.

And laminova what now? lol

So what car is part number 1103.54 off then? Would it be a part for example, from a 1.8xsi engine? Without looking I don't know if they run a heat exchanger or not. But the threaded part being discussed, is that off lower model 306's?

I have a 395mm one that I'm using as an expensive ornament at the moment. Like you I eventually plan on uprating the cooling system to cope with the increased demands.

I think mine has -10 fittings but think I should have went with -12, anyone know if you can simply swap the unions over?

I use a 19 row oil/air cooler on mine with the power it's running and it has no issues.

Do you really think you need a laminova cooler for 300bhp?

Exactly.... And not sure what engine that's actually from off the top of my head. It's simply a length of M20 thread with a hole through the centre. But yes it's from an engine without the heat exchanger like a 1.8 16v or possibly xsi.

I got my mocal 13 row cooler on just before pugfest and while giving it s**t all day in 30 degree heat the oil temp was fine.

I've got two 13 row coolers on mine at the moment just for the engine oil and in 30 degree heat it was getting pretty warm at the nordschleife.
Part of the reason i want to go with a laminova is because it will mean i have loads more room behind the bumper for other stuff, and having just a take off plate on the front of the block will mean i have plenty more space there for pipework etc, and the remote filter head will mean changing filters will be much easier too, it just seems like the ideal situation for what i'm wanting to do.

Where did you get yours from Graeme? I think i'll get a 395mm long one too, better to be safe than sorry and it's not like i'll be able to over cool the oil with it.

Precisely. These are popular with the touring car teams for a reason.

I was actually thinking it might be possible to use one of the dual Laminova units to cool the engine oil and traction fluid on the SC cars, leaving more room at the front for airflow into the radiator and intercooler.

Plus, there's not a risk of a frontal impact or a rouge stone piercing the cooler and dropping the oil.

I think I just ordered mine from tweeks after an alcohol fueled night. I'd thought about s/c cooling too but didn't realise you could get dual ones

I heard about these and they also can be used for cooling the charge aswell. There are a few firms who have machined custom manifolds and have these units embedded giving very good results.

Get it from Think Automotive in Isleworth, they are experts in all things oil/cooling related and will be able to guide you in selecting the appropriate sized heat exchanger. I just opted for the largest one and in the flesh it's a bit on the bulky side. In hindsight the small or medium unit woe probably have been sufficient. It's still never been used so I may try to exchange it for the medium unit later on down the line. It's important to note that the size of the unit is in no way as important as the size and efficiency of your water radiator. A laminova on a standard rad will be heavily compromised.

This is what i was thinking Yes

So yes you could save some space to start but you are likely going to have to upgrade to a larger/thicker radiator to handle the extra strain on the cooling system right? I think i would prefer to just go for decent oil cooler with some ducting to aid cooling if required.

at £1k+ for a dual combined unit I think I'll pass

Exactly, oil/air cooler will be fine for anybody doing trackdays.

The only reason touring cars ran them was because they have money to spend in the first place and they want to make the engine run at a certain temperature for 45 ish mins racing flat out.

The 306 btcc cars ran Laminovas alongside an oil>air cooler. They are designed to keep the oil within a certain temperature range, so the air cooler will cool the oil and then the laminova could warm it up again if the oil gets too cool. Generally the coolant warms up quicker than the oil too so it also helps warm the oil up from start up.

Personally I think they are overkill and certainly take up a lot of space with the additional coolant and oil hoses reqd. As Stan said, no budget and plenty of space they are excellent bits of kit but I wouldn't put one on my car unless I was having issues with oil temp. If you run a thermostatic oil cooler sandwich plate then your oil temp will have some control on it already...

I'd also agree with Jim and speak to Think Auto for any hoses, oil coolers and associated bits, bobs and friendly advice you could ever need!

You must have air flow issues. I run 1 13 row cooler and I can't get my oil over 100 degree no matter how hard I try and it does get a good thrashing on track.

Appreciate now I'm dry sump but even on wet sump it was the same.

Gotta say I did think 2 13 row coolers was excessive! There also quite restrictive so I'd get an oil pressure gauge fitted if I were you, just to be safe!

I ran a single 16 row one I think with a thermostatic sandwich plate and that did a great job, I did used to put a bit of card in front of it for winter trackdays mind!

My oil sits around 3-4 bar, mostly at 4 bar when on track. Last year i was getting a reported 115*c oil temp after a single lap on the nordschleife, the weather was bloody hot at around 30*c though but i'd still prefer it if i couldnt get it that high.

That's the coolers both sat directly behind the grille, so they should really be getting plenty of fresh cold air. Dunno

cosmicspanner fitted a laminova cooler to his low boost, Have a look at his thread.

He had a custom rad too.

With mine, I can run on track for 45 minutes without a break and see the oil temp only get as high as 110c.

That's a 19-row, situated behind the empty fog light hole on the driver's side. I would say you have potentially more issues than just needing a better oil cooler.

I don't know all the theory but maybe your 2x oil coolers are more restrictive than you think and not half as efficient as say a larger single item.

I used to get high temperatures with a single 19 row 235mm mocal cooler too on a different car with a different thermostatic take off plate, that was in direct airflow like the above coolers too. I'm beginning to think i'm just a harsh bugger on the engine. Laugh

What are your water temperatures like?

I've got my water temp down to 70 degree on your average trackday. If you can lower your water temp this will help control the oil too.
