Aftermarket oil cooler in CS?
 

Can I add an aftermarket oil cooler to my car and still stay in CS?

Nope. Oil cooler would put you in ASP. Really don't need it for AutoX though. I never had a problem getting mine cooled back down between runs. Just turn the AC on between runs to force the radiator fans to run.

Defrost on full heat cools it faster.

Are they really that sticky? I mean what could an oil cooler do to a car.. not even 0.01 HP gain.

Yes. It is illegal.

What temp is considered "hot". Quite honestly I don't even pay that much attention, but after reading these forums, I'm thinking maybe I should. I have seen mine get up to around 230 on the street (spirited drive, not thrashing) in the summer. If folks are really having oil temp issues in a stock class 40-60 second autocross run, then Nissan has issues and I'm taking mine back to the dealer and demanding they fix it. Also I wonder if this was a known problem ie service bulletins, etc if an oil cooler would be acceptable in stock class?

Bye the way 03threefiftyz, that is one awesome photo!!

You can leave it there all you want, they just won't touch it

when I did a quick test on a dyno of when the power goes down, it started to get down as soon as the oil got to 104 C ( 219F ) 7-8whp mostly in mid-range.

I should have tried at 240F
