Oil Cooler
 

Anyone running an oil cooler around here? I was wondering what was involved with putting in a universal aftermarket unit? Wouldn't mind the Greddy one but who knows when it will be available.

Perrin wrote about one in their exhaust post yesterday.

^This.

Perrin was almost 100% certain it would help eliminate the discrepancy of HP numbers being shown on dynos as the engine runs way to hot most of the time.

They're not to difficult to install. Thermostat is installed where the oil filter goes and the filter sits on top of it. You normally install the cooler in front of radiator and on the BRZ it looks as if it will be on the passenger side. Two lines are then connected between the two. The most important aspect is picking the right size cooler. Too small and it doesn't do the job and too large the oil temp can stay too low. Needs to be above 180 degrees and below 220 degrees during normal operations.

The oil cooler I have on the race car is not T-stat'd. I really like the Perrin option for a street car with a T-Stat so you're not driving to and from worth with overly cooled oil.

This might be a something I consider so I can just run the 0w-20 oil at the track without worrying.

I wonder if this kit will fit for people going turbo with intercooler

Didn't think about the thermostat.... How about a link to a high quality universal unit that will do the job?

Also, is "over cooling the oil" that big of a deal considering we are running 0W-20 in our cars? Seems like it would function fine at low temperatures given the weight. Please educate me if I am mistaken.

Oil is designed to work in a certain temperature range, and the viscosity rating system reflects this. the first number represents the viscosity at lower temps, while the second number represents the viscosity at 100 Deg C. These numbers simply compare the rated oil to an SAE standard.

Therefore if you were to run your oil at 70 Deg C(over cooling it) it would be "thicker" than was designed for the engine, and your oil pressure would be higher.

Doesn't it look like the STi concept has an oil cooler?

Why use an oil cooler if you ain't got no boost?

^Check out the Perrin thread about their exhaust. Oil temps were running high. Maybe a reason for dyno result variance.

Because oil gets hot even in an NA app..

Worse if you track your vehicle.

This car needs an oil cooler imo for any track work.

heat is the enemy of anything mechanical, so keeping the oil temp in check could theoretically prolong engine life in the long-term
