Announcing the release of the STILLEN race oil cooler

import111 · 09-03-2009, 01:41 PM

There are other options for a thermostatic sandwich plate if Stillen doesn't end up offering one. I am in Tucson, AZ. so I doubt I will need one, but once I get a large oil cooler (probably Stillen) I will keep an eye on oil temps as winter comes.

The long wait is over! We are proud to announce the STILLEN 370Z Race oil cooler. Due to demand from the heavy track guys on the forum we have made a few modifications to our current street oil cooler so that it will be even more effective for track use.

Currently STILLEN is using a Setrab Oil Cooler in our street kit which is designed specifically for engine’s producing between 220-310 horsepower. This is why we chose this core to integrate into our Nissan 370Z oil cooler kit. It is a good size and it has been proven to work very well. It prevents the car from going into limp mode by reducing oil temperatures below the factory limited controls.

However, for the guys that are really pushing their cars hard on the race track we feel that they would benefit from an even larger oil cooler option. The current Setrab oil cooler unit we are using is designed to dissipate around 37,000 BTU/HR. This new Setrab oil cooler is designed to dissipate around 60,000 BTU/HR which is about an additional 20-30 degrees removed from the oil temperature.

We have found that when pushed hard on the race track during 20-30 minute track sessions the street oil cooler kit prevents the car from going into limp mode but the oil temperatures still reach around 240-260 degrees. These temperatures aren’t bad but we would like to see them a little lower. The new race oil cooler option will give an even greater drop in temperature of around 20-30 degrees. This new oil cooler core has twice the surface area of the street core but will be a direct bolt-in and will be able to work with the same lines as the street oil cooler. This means that anyone with the street cooler can upgrade to the race cooler with minimal fuss. The race oil cooler uses a 26 row core, versus the street oil cooler's 19 rows.

For a limited time (30 days) we will be offering an upgrade path for our customer’s who have purchased the street oil cooler and would like to upgrade to the race cooler. This upgrade kit will include the new core, mounting bracket, and all of the necessary mounting hardware. For more information on the upgrade kit and pricing please call in and speak with one of our representatives.

Here is a link to the two oil cooler options:

Here is a comparison photo of the two radiator cores. The one in front is the street core, the one in back is the race core.

Very nice, Is that a Thermostatic oil filter adapter .

Very well design

blackbird · 09-03-2009, 07:05 PM

Will it fit on a 370Z with Gen 3 intake?

JoeD · 09-03-2009, 07:43 PM

Looks like a great product!! Question I have, though, is without the thermostatic plate...will oil-temps be too low while driving casually on the street or perhaps cruising on the freeway on a cool night? From testimonials, it appears as though the street version did such a phenomenal job at lowering temps that things are right at optimal levels for hard or normal street-driving.

Part of me however thinks that with either the street or track setup, oil-temps will stabilize in the 180-190 range, and the race version will just make it damn near impossible to see temps above 230 on the track. Am I correct in that assessment?

ResIpsa · 09-04-2009, 08:19 AM

Mine is in the mail!

Thanks Stillen for the work you guys do!

+1

My thoughts also, with my question above, yours is worded better.

Shunya · 09-04-2009, 08:24 AM

Looking good Stillen~!
Pricing isn't too bad either :P
any special pricings for us?

ResIpsa · 09-04-2009, 09:18 AM

Check out this thread. This guy fabricated a oil cooler cover out of thin sheets of stainless steel (& packing foam but I am not sure what the foam was used for...).

This could be a cheap solution to over cooling.

Sorry for not getting back to you sooner. I've been on the dyno and in the shop the past few days with our 370.

The street oil cooler is what we would like to recommend for 99% of the owner's of the 370Z's. The race oil cooler will be a bit overkill for the majority of people and just won't be necessary. The street oil cooler has been proven to work very well and offer a big reduction in temperatures. Even on the track the street cooler is working very well. We just wanted to see the temperatures get a little bit lower while on the race track.

HAHA. I wear quite a few hats around here but last week we were doing a bunch of video's of our performance parts. Intake, exhaust, headers, HFC's and their dyno numbers as well as their sounds. FI video's aren't far from being ready but it will be a little while longer.

So is there a dis-advantage to running the race cooler on the street? I was just driving in traffic yesterday (it was hot, bout 98deg) and was not even close to driving aggressive, my oil temp was fluctuating from 240 - 250. Even on a cool day, my average oil temp is 220. If the race cooler has a 40 degree reduction, would still be at 180 right? Also, I plan on running a supercharger, I have a feeling this will kick up temperatures a bit. Is running the car with too low an oil temp bad, and what is considered too low for this car?
I notice that the car runs really good and feels way more responsive when first starting up in the morning, but as soon as it starts creeping into the 200 range it starts to feel sluggish.

Judging by your list of modifications in your sig. I'm assuming you do not currently have our street oil cooler? I would suggest starting with this. For street use I think you would have a hard time pushing the temperatures beyond a safe point with the street cooler. The race cooler might be a bit much.

When we say that the race cooler might be a bit much we mean that in two ways: 1) financially speaking-At the end of the day the race cooler is substantially more expensive. We know this but the core is substantially larger so the cost is going to be more. I firmly believe in the philosophy that if you don't need to spend the money, why spend it? If you don't plan on driving your car hard on the race track then the street cooler will be fine for you. 2) Streetability- With the race oil cooler in particular you will want to have a thermostatic plate installed. We will have this option soon, we're just trying to find a source so that we can be competitively priced. As it stands right now you can pick up a thermostatic plate for pretty cheap from sources like Amazon.

It is possible to have your oil run too cold. 180-200 degrees is pretty much optimum and realistically 180 is on the cool side.

This may be too obvious to mention, but when you first start it up in the morning, it will run rich. This would make it feel more responsive. The ECU will obviously take that down after a few minutes of run time (it's usually only a minute or two for me at around 50-60 degrees ambient).

If the effect you're talking about is different and lasts all the way up to 190 degree oil temp, then please disregard this post
