Some Over cooling of the oil due to sensor position???
I moved my OEM drain plug oil temp sensor to a sandwich adapter tapped for 14mm.
Prior to doing this on cold days the oil temp didn't move.
So now I am tracking oil temp in the actual stream of oil and I see much more consistent oil temps in 80 - 90 C range.
This is in highway driving 75mph on 100 degree F days. I am sure the track speeds puts a lot more heat in the oil. Perhaps more than is being measured with a pan mounted sensor. Depending on mixing of the oil and air cooling of the sensor you may see a stagnant low temp rather than circulating oil temp.
Heat wrap the down pipe and hot side of turbo as well as manifold. Seem to work on the street for me, some downsides if you get a lot of blow by could act as a wick for burning oil.
Here are some real-world pics of a Muscle car here in NZ.
Using a PWR radiator and oil cooler (tube/fin core) which is bolted together.
800+ whp from a Nascar engine, not seeing more than 90ºC oil temp for a 15minute race.
I'd love to make a setup like this for the Evo market, but I dont think people would pay $3000nzd for this setup.
Not only that but you just wouldnt fit a double stacked radiator and oil cooler setup in the front of an evo. its so tight as it is with an aftermarket turbo installed. i think youd be better off to try make a custom sized radiator that mounts in where the air con cooler normally sits or a long but short in height oil cooler that could mount into the gap between intercooler and radiator. also a possible option would be a twin loop oil cooler setup in place of the factory one?
have you or anybody you know of tried to make a proper duct to feed the cooler itself from the bumper? I remember the factory bumper and cooler on my evo 7 bumper had some sort of plastic air guide setup there.
Im curious to try this myself as ive seen on hot days oil temp up around 140c at the end of a race.
It works on radiators so i assume it would work on an oil cooler also. could also try a fan on the back side to pull air through it?
OEM setups can run the Varis/rexpeed oil cooler duct feeds off the right front bumper inlet

On the VI there was a oil cooler vent on the bumper for this exact reason. I saw a IX here add that mod and I did to mine as well. I never pulled data on it to see if it made much of a difference though
Finally got under the car and looked at the pan - it was delivered straight to the shop, and the shop installed and I haven't been under the car since. Curious, what's with the bird footprints? Hard to believe the shop dropped the car down on something here, some design element?

Those are welds dude. Tab and slot design for the internal pieces to the bottom plate.
Yup - for ease of manufacture and accuracy, everything is laser cut and folded with tags for initial fitment before welding.
Because they are zinc plated rather than painted or powdercoated, they are easy to see!
Went to the track last week with the Infinite Evo testing car (Evo 6).
400whp with A052 tyres (245/40R17).
This is the scatter graph oil pressure data for all 4 sessions completed for the day. Around 28 laps total.
Using the Tomei Thermostat Killer there is more pressure drop between the oil filter housing and mains gallery readings due to more pressure loss through the oil cooler.
If you run the standard oil thermostat, the difference is around 12psi rather than 20psi.
The little hazy sprinkles of dots below the main oil pressure trend is from Mivec activation, when it swings the cam the oil pressure drops around 6-8psi while it's moving.

HD or pukekohe?
Looks good! pretty much drysump levels of stability

Hampton - managed a 1:13.6 lap time. Matt G (track pro) did a 1:12.9 so i'm happy with that.
Doing SSB uprights next, so it was good to get some true comparison data.
I had a play around with RaceRender3, it's very easy to use.
Accepts Motec CSV files, doesn't take much setup.
Same video as before, and another lap within 0.1sec to back it up.
I've included oil pressure data on the overlay also
Note: This is oil pressure at the mains gallery. 20psi lower than oil pressure at the oil filter housing.
So 70psi is actually 90psi at the oil filter housing.
The small "wiggles" of oil pressure is from Mivec activation/movement, typically 5-7 psi.
