+1 On the over-cooling. I have the Stillen track cooler with a Mocal 180 degree thermostatic sandwich plate and it is a real problem heating up in the winter. On cold days I have to take painters tape and cover my front grill (not very pretty...).

However, I do track my car so I can live with it.

The thermo plate is not working properly?

I was confused about this too until I researched it. Thermo plates are ALWAYS circulating some oil. This is to avoid the thermal shock of a Thermostat opening fully at 180 degrees into a cold cooler core. As the temp hits the trigger point More oil goes to the plate and less through the bypass (which is naturally the path of least resistance). So basically, the cooler is always functioning at some level, just more so when the oil is hot and more fluid is diverted through it as determined by the thermostat. This is why a cooler starts getting warm (with a thermostat) as soon as the engine is started, and why the oil may not get up to temp in cold situations. This reinforces the need to properly size the cooler. More is not better unless you have track needs like Resipsa and then you have to make some special accommodations (blocking part of ther core) for normal street use.. Putting a Large "race" cooler on a car with no thermostat would be problematic in cooler climes.

Do you think that using a 210 degree thermostat would help? In theory it should be more closed at temperatures approaching 180 degrees and allow the oil to heat up a little faster.

I honestly don't think so.....Getting a thermo plate with anything but a 180- opening point would be a special order. 180 is the standard. I'm not sure the higher temp would change the warm up bleed rate.

My temps range from 180-210 under virtually all conditions with my Cooler.

I found a 215 degree bypass unit for $143. A bit more expensive than the thermostatic plate, plus a passive plate is still required.

If it's a pure Bypass and not a bleed like the Thermostatic plate, then that might be a good thing. Seems it would keep the oil in the 215-220 range when the cooler is kicked in..
