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..

I sent a message to Canton Racing to find out. It has 4 fittings, the primary send and return lines, and the secondary send and return lines to the cooler. It says it is a bypass but doesn't say whether it is absolute or not or at what temperature it begins opening vs being fully open.

Let us know Chris....Mocal also has an outboard thermostat for considerably less $$...Guess we need to find that out as well..I'll shoot them an email..

Canton Racing replied.

They stated that the thermostat is a complete bypass, with no flow to cooler until the oil temp reaches 215 degrees. I wasn't able to get them to tell me exact opening and closing temperatures, but if it was centered around 215 or began opening at 215 it would be great.

The price is $143 from LPI Racing, plus more $$ for the extra fittings and lines.

Expensive but seems like a much better solution, especially people like me where the fall and spring can be pretty cold. Plus I plan on using the 34 row Setrab so I definitely don't want any circulation going through that giant cooler until I need it.
