Should I get an oil cooler?

ZMan8

I like people who write "smart a$$ comments"

To answer you, Yes I do know the stock air intake is a Cold air intake that is why mine is still stock. But if my chemistry knowledge is correct heat transfers goes from hot areas to cold. Therefore, heat will transfer from the hot block to all surrounding parts whether you drove forward, backward or sideways. Our engine bays are packed so there isn't many places for that heat to go but other parts. The plastic intakes do better than metal but they still heat up. Along with the maf sensors.

I don't have the tools or time to make this study. But I would like to see a test done where temperature and humidity Are constants. And the person measures oil temperature vs air intake temperatures.

Boys your going further and starting a whole new thread about CAI vs OP original question of having the need of an oil cooler.

IMHO all of you guys over here are exceptionally correct with all your analysis, Laws of Heat transfer and research data what else?..... that is why I love this forum.

Lets not overwhelm OP with technical data which might do two things...
1. We can probably scare him/overwhelm him to think he just bought a highly sophisticated machine that need all this things to make his car perform to a level that he even doesn't want to go through in the first place.

2. We can influence this guy to go with us in the Dark Side of being highly anally technical and damn obsessed of making the Z a super car which most of us would want to do. Burn the money away for the LOVE of performance. Nothing wrong with this its just a matter of choice and preference.

Going back to OP's question if you do not drive your car hard like us over here BIG Boys and all.
Then save yourself with the money and enjoy the car as you do not need the oil cooler.

But then if you want to go a different path just like in the movie MATRIX when you want all possibilities will be on your hand then choose between the blue pill and the red pill....Your choice buddy.

Either way you are welcome...Just be ready for a HELL of a RIDE!

BTW dont forget your credit card...lol

I understand trying to apply logic and reason to a hypothesis.

The problem here is, the engineering and observed data don't jive with your hypothesis Yes heat transfers, but the rate of transfer is vastly different across different materials and states of matter.

Heat soak isn't going to occur to the point of pulling significant timing. Simply measure IAT from a readout to see exactly what is going on. If you are stuck at a stop light for a few minutes, IAT may creep up a few deg F but once you start moving its back to ambient. The intake is not hanging on top of the block.

The thermodynamics here are not much different from car to car. Air temp is going to matter to fuel/timing. If folks buy an oil cooler with the expectation its going to improve performance on a street car, I think that's a misinformed purchasing decision.

spot on. I have the tools to do a test, which I did, oil temp doesn't have direct effect on engine performance. my car made the same power at 200 vs 270. just stick an electrical tape to the gauge and you won't think twice about it

.... and there you go
