Have you looked at the KE thermostat that is intergrated in the KE oil filter mount? It is a super part that holds the oil temp spot on all condensation issues disappear. Keith also used to sell a remote thermostat.

Hello all.
What's everyone using for a bypass thermostat for your oil coolers?
I need one that has -12 capability.
I can't use anything that attaches where the oil filter boss is as I'm dry sump.
Thanks.


Have to ask why -12 and not a -10?
And I would run a thermostat. KE

My feed from my dry sump pump is -12 and I don't want to choke it down.

Its going to get choked down some where. lol
Will be a lot easier to plumb smaller size. -10 will work fine. I feel like one of the ball breakers on another thread. have to laugh.:boat:

Theres been a time or two as to whether or not you need coolers at all especially running in the Great Lakes. Pulled mine years ago for replacement and went out for a weekend thinking I was gonna have to be idling the whole weekend and partying at the cove NOT. It was a good test to say the least. It varied Some depending engine load and rpm however I never went over 200 deg oil temps. That was a twin engine app with 454/485 hp's. Average cruising temps were about 185.

Last boat I bought to restore didn't have coolers on from the factory. It was a 79 with twin 454 330's. Ran hard across the pond before starting restoration. No issues.

It is what it is. These big power plants that seems to be the norm now a days I wouldn't consider going without sizable coolers though.

Buddy of mine kept loosing engines wiping main and rod bearings had no cooler. 600hp small blocks supercharged.
Run no cooler with any kind of power you will have JUNK when your done.

Guess I was fortunate. Again this was with much less power and monitoring oil temps.

Actually, it's not going to get restricted anywhere. Lol.
Running a -12 line is no harder than running a -10. :angry-smiley-038:

I've got to get I touch with Ilmor today and tell them it was a big waste of time and would have been way easier for them to use a -10 when they built this engine originally. I'm sure they will appreciate the info. :lolhit:
