Either should preform as well as the larger Mocal Laminova or like a 30 row oil to air cooler and will give way more consistent temperature regulation and oil pressure drop than the stock coolers (especially when the oil to water ones are installed without a thermostat)
Wondering if anyone has experience, advice, or their two cents to throw in about low-temp oil cooler 'stats. The stock ones have an opening temp of 194 °F. These aftermarket ones from Rotary Performance open at 165 °F. At $90 a pop (and I'd need two), they're a bit pricey. Can anyone testify to this type of cooling mod?
Thermostats. Oil thermostats, as mentioned, control the flow of oil to the oil cooler. They are not always necessary but should be considered, especially on road cars. The thermostat works just like the one in your engines water system, only that it restricts the amount of cold oil that goes to the cooler until it reaches its set opening ...
If the Mocal thermostat is like the OEM thermostat I think the oil is supposed to do a U turn at the thermostat when cold and then flow through to the oil cooler when warm.
Mocal inline oil thermostats are fitted into oil lines between the engine and the oil cooler. The oil thermostat diverts oil from the cooler until the oil reaches 80°C. Mocal oil sandwich plate with built in thermostat.
I think reviews are going to vary based on the car. Throw an ebay special on a well designed 4 cylinder, probably going to work fantastically as they dont have oil temp issues to begin with. Throw it on an LS that is notorious for 300f oil temps, it may not do anything at all.
It is therefore desirable to control of the oil flow through the cooler by a thermostatic device, we call an oilstat, set to divert oil to the cooler at 80°C (although a wide range of settings is available for special applications).
