It's possible. But you will find yourself hitting limp mode very quickly. It is very likely even on your 1st track day you will find yourself in your 1st session of the day just feeling things out not really getting to the point where you'll hit limp mode. It won't be long though before the temperature rises through the day and you start to improve, braking later, accelerating sooner, harder and...then you hit 260 degrees F and that's when you wish you got an oil cooler. Limp mode will limit you to ~3500 RPM and you'll be cruising around the track like a grand mother. Please understand the oil cooler will NOT eliminate LIMP MODE. It will only delay it, providing you a buffer that allows you to get a couple more hot laps out there before the inevitable happens.
If you think you even have the slightest bit of competitiveness in you or are really passionate about motorsports, I would get a 34 row oil cooler ASAP.
