Oil cooler effectiveness

[Bill Bayard]

4 questions for guys who have oil coolers installed:

1.What temp does your oil get to, and under what conditions(street/race)?

2.What should "normal" oil temp be?

3.How much of a difference in oil temp did you see after installing the cooler?

4.What difference did the oil cooler make, if any, to coolant temp?

Thanks for any input!

Hi Bill,

From past experiences with oil coolers

For "non-race" applications, you MUST use a thermostat bypass so that the oil bypasses the cooler until it comes up to temperature. If you don't the oil will not get hot enough to burn off contaminates and you could have problems with engine life/performance.

Dave,

Thanks! That was question #5! Only four to go!

Bill,

I have 2 oil coolers on the left side inside the engine room

Street conditions: 90° C (no bypass)
Track: more than 120°C

Normal oil temp is considered in a range from 85°C to 110°

the 2nd oil cooler used allowed to delay the increase of the oil temp but the values were almost the same (espacially on tack)

I saw no impact on coolant Temp.

In fact the most important, if want to have a big efficiency of your cooler, is to canalize the air flow to the radiator, like a tunnel from the scoop directly to the radiator surface, and the air shouldn't have any other possibility that to cross over the wiring, if you do that you will notice a big difference. Around minus 10°C on track conditions.I didn't do that on my car yet but i think about it ! /ubbthreads/images/graemlins/grin.gif

Last point, if you don't use synthetic oil over 120°C pray for your engine on track conditions ...

Sorry to use °C you will make the conversion for °F /ubbthreads/images/graemlins/smirk.gif

Thank you Fred!

That answers my questions and then some! /ubbthreads/images/graemlins/cool.gif
