I've never used a regular air oil cooler so I can't comment on that.


However, I will say it keeps temps down much better than not having one. If you plan on driving hard, an oil cooler of some kind is a must.

 

Jon....can you post what the model # is of the laminova? Thanks!

 

scratch my other post I see it but what size lines are you running for oil and water?

 

Oil lines were -10AN, I can't remember the water size off hand, it was the same ID as the stock "oil cooler" lines.

 

Old topic i know and not sure if the OP is still on here.

I have got the middle sized Laminova and im going to fit it tomorrow. From what i have seen of your install it looks like you get your coolant from the OEM oil cooler coolant ports. Did you use a restrictor inside the Laminova to make up for the lack of water flow? The OEM barb connector on the block is 13mm ID which doesn't allow alot of flow compared to say a 30mm radiator line. I know Laminova recommend using a restrictor for low coolant flows.

My car is pretty stock engine wise and i just want to take 10c off of my trackday oil temperatures as last time out i hit 130c. Did you ever test this out on track?

Thanks

 

Well i finished installing the cooler today. Had a few issues getting the air locks out of the coolant lines from the place where the old sandwich adapter sat. Oil pressure measurements from the OEM sender are as follows

92c oil temp
idle 14psi
before vtec 85psi
6000-9000 rpm 70-75psi

This is using a sandwich plate with no thermostat and 10an lines and fittings. I might possibly move up to 12an but not sure if its worth the bother.

 

I had an evening trackday on tuesday 25c outside so a nice warm day to get my tyres nice and hot. Highest oil temperature i saw in the sump was 103c and noticed abit of pressure drop during the sessions as the oil thinned out. Lowest reading i saw was 66si during vtec. Im going to fit the larger laminova because it flows more oil with less restriction so i can hopefully bump up the pressures abit as well as add abit of extra cooling. I will see what my pressure are like with with this installed before opting the 12an route

 

Any pics of the setup? Or did you basically duplicate specops's setup? I was looking at doing a laminova oil cooler setup w/ the larger cooler but couldn't justify the (almost double) cost of this over an air cooled setup. A water/water cooler has some nice advantages over a air/water. I'd be interested to hear how oil temps fare w/ the larger laminova cooler.

Also, did you log temps before the oil cooler so you can compare afterwards?

 

Hi,

My current set up is basically the same as Spec Ops except the smaller cooler. There are alot of bonus's with the Laminova, especially how robust it is. No stone will flick up and break it like a traditional oil cooler.

I made a mistake getting the smaller cooler, if i had of read the charts correctly i would of realized that at flow rates over 40 litres a minute that the Laminova will start causing a fair bit of restriction to the oil pressures. The S2000 flows 60 LPM at 6000rpm so it needs to bigger cooler to allow the additional flow. Cooling wise it done a fair bit to the oil temperature.

Last track day similar conditions i saw temperatures of 130c at the sandwich plate. This time im pretty sure the most at the sump sender was 102c but the recover speed when you eased off for a few corners was much greater. Changing to the larger cooler will only improve warm up, cool down and pressure losses. I have another trackday in August so assuming the weather is good i will have it all fitted and will test again.

 

Well i fitted the larger laminova today and after some swearing at the hit and miss AN10 fittings that sealed fine before and wont now i managed to get it to seal properly. Remade the joint about 5 times and was about to give up when it stopped leaking on the last attempt.





First impressions are that idle pressures are unchanged and on the low side. 14psi at 800rpm but with aircon on they can bump up to 17psi with just 100rpm idle speed difference. Straight away thou i noticed that at 3000rpm i was hitting 85psi much easier and quicker compared to the medium sized cooler. During the vtec crossover oil pressure now stays into the high 70's and sometimes hits 80psi. On my last tuesday on track i was lucky to get 70psi once the oil had warmed up.

IMO i would not fit anything other than the larger cooler on the S2000. My testing shows that the medium sized cooler restricts oil flow alot and in the longterm this cant be a good thing. The larger cooler is designed to handle flows larger than 60 litres per minute where as the medium one only can handle 40 litres and then starts becoming a quite big restriction to oil flow.

Ignore the cable ties they are temporary until i make some brackets, just incase anyone is interest the cooler is mounted on a 15mm foam which stops any of the oil pump pulses being pushed through the chassis and into the cabin. If you have ever rigidly fitted a air to oil cooler then you will know what im on about! It also lifts the cooler above the chassis rail edges on the front cross member. Steel rubbing against aluminium wouldnt be a good idea!

There is more than enough room to fit the larger cooler, its abit close to the AC lines on a RHD car but nothing that cant be overcome with some clever placement.

The OEM cooler plate uses 13mm ID water hose so you need some hose and a 16mm to 13mm silicon reducer on each side of the laminova. Luckily i managed to get some 90 degree angles with the reducer built in which saved making more joints.
