Hey Guys,
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.
