The need for an oil cooler when going FI (Temperature Data Inside)

Where is the factory oil temp sensor located?

What do you guys consider a safe temp range?

I have a blower sitting at home for the car, but I am scared to put it on, as the car runs wicked hot stock. Don't even want to know what it's going to run once boosted

It's going to run the same numbers. It just gets there faster with FI.

Are you sure?

Yes. On the first page I posted a link to a website that tested more than a dozen oils at higher temps for an hour, check that site out. It's got some useful info for those looking to track their car.

Always going to have some adverse opinions on the forum.

Some of us have been collecting data for well over a year now.
195F - 220F is common within 10 minutes of spirited driving and is completely normal on a stock car.

Any Toyota/Subaru Engineer would have tested and experienced this during development.

Ranges and Data Collected:
100-169F Warm Up Phase, high oil pressures
170-189F Near Operating temps, oil pressures still higher
190-225F Normal Operating Range, oil pressures normalize
225-245F Middle End of operating range for track use, 5% drop in oil pressures
245-255F Upper End of operating ranges for track use, 10% further drop in pressures on 0w20
255-265F Red Zone of operating ranges for track zone, 0w20 starts to thin, oil pressures drop to questionable range.
265F+ Playing with fire on 0w20

The factory sensor is below the oil filter next to the oil pressure switch.

Generally 250 is a little on the high side but many cars run right around there on the track. Above 260 and you definitely want to look at cooling things a bit more. What kind of oil were you running?

One week old car all stock as off the showroom floor including tire pressure. LOL

Except for a track pipe - muffler delete.

So I need an oil cooler. I plan on running more than 3 fucking laps...

It would do your engine a great benefit if you do so.

[TmP]

On it.
Problem is, there seem to be none that fit the KW blower kit...

Yeah we need something for this kit. @KraftWerks are you guys planning to release a oil cooler kit for the SC kit?

You might want to call them up to see where they're at in their production phase.

About to pull the trigger on the Kraftwerks kit.

Oil cooler necessary for on the street and daily driving or will I be able to get by without? I figure I won't push it to extreme levels like a track would for starters, but it's also not really cool during summers here. Plan on getting the Kraftwerks oil cooler when it releases for that piece of mind regardless of daily driving.

You don't need an oil cooler if you don't drive the car.
