oil cooler thermostat
can I just remove the oil cooler thermostat and provide full flow to oil cooler. I live in a tropical climate and have trouble keeping oil viscocity up running oil cooled turbo and tracking. oil starts at 5 bar on track but after a few hard laps the viscocity drops to 4 then 3. after cool down pressure is back to 5. I have changed the oil cooler to a front mounted mazda rx7 cooler.

We've experimented a little with this on a track car and we eventually put the thermostat back. Someone explained to me once that as the oil warms up and circulates in the engine, it will not be "tempted" to take the route of the oil cooler unless it is forced to do so. It seems that the cooler oil will act as a wall. So by removing the t-stat we saw the same temperatures and at times even increased temperatures.
If you could force the oil to always go through the oil cooler than it might be ok, but if there is an alternate path, it won't work in my opinion.

Thanks for the reply guys; I'm going to try toset the oil thermostat on open only; looks like fully open only moves the thermostat 1.5cm at 200 F. Im going to take the pin out and just use a spacer. any one have diagrams?
