One-Off Oil Cooler?

That is correct but IMO (and based on my oil pressure gauge) it doesn't maintain high enough pressure in the upper RPM when warm/hot, so I run 5W30 which does.. that does increase heat a bit though.

Have you found that the Higher oil viscosity increased the heat?

I'm running 10/30 right now

Are you running -8 or -10 line for your oil cooler?

I didn't have the temp gauge installed when I was using the 0W-20, so I can't answer that with data. Thicker oil *should* result in higher temps though as it prevents some heat transfer which adds heat overall.

For your other question, -10.

Those tabs look a little concerning. should be supported top and bottom if your mounting it like that. I don't like the idea of the cooler being mounted over the engine no way for it to pull cool air. I'm thinking integrated heat exchanger or mounting mine on the hot side of the intercooler since it's way over sized.


I'll post up once I make something happen.

I would rubber mount the cooler, at least something to remove vibrations being directed to the cooler. There are lots of brazed or epoxied joints in a cooler that won't like vibration. A cracked cooler makes a mess. "Well-nuts" or something similar should work.

I run a water to oil cooler in my racecar (not the FRS) and they also typically reduce the length of the oil lines and reduce the need for an oil thermostat.

The shorter the oil lines, the better...

I so wanted to do this with a hood scoop, to leave more air flow to the intercooler. Looks like you got to top mount before me.. lol

I was just debating this last night! what size cooler and how did it turn out? I want to add a fan as well.
