hey guys

i want to start looking down the path of an engine oil cooler to keep temps under control next time at the track.

Does anyone know how to plumb this setup in? would it require an oil filter relocation plate or is there another place to do it? I will also want to go with a temperature bypass so oil gets a chance to warm up to 60-80 degrees before it goes through a front mounted oil cooler.

people in the know, speak up!

You do not need a relocation kit, just a sandwitch plate.

It sits between the filter and the block and basically any oil going to your filter now has to go through the oil cooler.

Other options include ribbed sumps, extra capacity sumps and a few others.

I don't think you need it mate and it will add another point of failure to the engine which is always a bad thing when dealing with oil.

thats true, but my thoughts are the amount of extra heat generated by the supercharger plus me flogging the ring out of the car on the track may warrent a cooler.

Oil temp shouldn't be a problem on the track, unless you are doing a hell of alot of laps each session, which you should avoid. Really its much nicer on the car to keep it at 5-7 laps per session, rather than say 10-15 I've found after 5-7 laps fatigue starts setting in, so you're likely to be going slower, or have a higher chance of making mistakes.

At this point IMO it makes little sense to keep pushing, at this point everything in your car is will tend to be geting quite hot, accelerating wear of consumables, and increasing chances of something breaking, cooking power steering fluid etc.

Although It's still nice to have an oil cooler for pace of mind I guess, especially with your setup. I'll be interested to see what you end up doing Jase, dependong on cost I might go the same route, as I seem to be hitting the track pretty frequently now, and am gonna continue to.

you may have trouble fitting one as the s/c oil pickup is where the after market sandwich adaptor would go...


and it is a fantastic idea, increases oil capacity and stabilises temp.. should be included in the kit

It's something I have considered (as well as an aluminium radiator). You think a supercharger heats things up, try sticking 2 exhaust gas powered compressors in a confined space lol

One of the Jap brands does a kit, I think its GReddy, with cooler, lines, temp switch, bypass etc. Dunno how much though. Need to be carefull with engine oil temp though, I had a oil only cooled Turbo, no water cooling, years ago and put a cooler on it for the return to sump, the engine lunched a set of bearings very quickly, so I took it off.

Cheap quick hint: remove the plastic sheets under the engine at the front. This exposes the sump to fresh air. Unless u have had them removed already with your front spoiler installation....?

does the 3000gt have a factory oil cooler????

might be a "factory" soln

Don't know about on the magnas, but on a previous car I owned I removed these (because they were pretty much busted anyway), and within about 3 months my cooling fan had sucked so much crap into the radiator fins that the car would overheat if driven for more than 30 minutes. So yeah - I wouldn't bother taking those thingys off, and to be honest.... I don't think it would make bugger all difference to the oil temp.

Have a look at www.perma-cool.com. They do universal fit coolers and a remote oil thermostat, which is what you'd need to get the oil warm before it starts passing through the cooler.

If you're flogging the life out of your car for a decent length of time, it'd probably be a good idea. I've heard that engine oil can run anything up to 20% hotter than coolant, which is pretty bloody hot, especially in a FI motor.

How does your oil hold up during track days?

They also help with areodynamics.

In a standard Magna (no spoilers etc) the bottom of front bar extends far enough towards the engine and covers the bottom of the radiator preventing any other air flow than the flow through the front grill, so it's ok.
Yep, I didn't mean it to be the Mother Of All Fixes and instant 20% improvement in power gain... just a minor thing to consider, since most Magnas have these plastic sheets flapping about anyway. Just use tidy metal bracket to brace the wheel arc sheets to the front bar.
Where as a very good way to dissipate heat from engine bay in general would be large vents on the bonnet - but not in front of the cabin intake vents - u don't wanna breath the engine bay air.... :shock:
Proper oil cooler is the only way to go for such hard driving, provided the oil actually does get that hot. Has anyone done tests in oil temps (in Magna) to see the diff between "normal" driving and track-gunning? Also, which oils can handle higher temps? There's something to ponder, eh.

They also help with areodynamics.

Bit off the subject, but very interesting point. What kind of experiments did u do? How much difference did u record?

I see where you are getting at, but no I didn't do any experiments:D . I based this solely off engineering papers I have read regarding under car aerodynamics. Also Autospeed has a few articles where they play around with under car fairing. And in every case they found leaving (and improving) the factory shrouding especially on the front, reduced drag and front end lift at higher speeds.

It basically smooths out the under car air flow (reducing turbulence), this gets more laminar air flow, witch creates a lower pressure zone under the car. Look at the underside of an R34 skyline GTR, almost the whole front half of the car is covered flat with plastic shrouding.

Yep, all true theory. Different cars, different aerodynamics. And then we go and lower the cars to change that :D. Also installing mag wheels with blade shape spokes, like my ROH Adrenalins most likely have negative effect on aero. But question is, how much diff does it make on our legal speeds. Most driving is done max 80 kph anyway. Except ppl at country or track of course. Tyre type, traction, pressure, open windows, rear wings, front fog light holes etc etc affect aero too.
But aaanyway, way off the topic and Jase is gonna hammer us soon with an oil cooler if we don't leave his post to subject. :redface:

Lowering the car can only help in aiding under car airflow :)


But question is, how much diff does it make on our legal speeds.

Apparently the Magnas best fuel efficiency figures are attained at 90kph, so obviously the overs drag coefficient plays a part in this. Take the shrouds off and drive at 100kph and I think you will notice a change in fuel economy.

But yes BACK ON TOPIC, I don't feel like copping a smack from an oil cooler core. :shock:
