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.

Thanks Chris....I dug a little more into the Mocal external hermostat. Turns out it works just like the take-off plates:

Quote:

Cold oil enters the
thermostat and is bypassed through the center of the
unit returning to engine (figure 1). During warm-up
the thermostat never closes off oil flow to the cooler,
rather, it offers a less restrictive path for the oil to flow*
allowing the cooler to acclimate to system
temperature. As oil warms to 180 degrees (200 in high
temp versions) the operating "waxstat" closes the
bypass permitting full flow to cooler (figure 2).
*percentage of oil bypass can vary up to the point
where the bypass is closed and full flow to the cooler

Looks ike the Canton is the only full shut-off option out there (so far)
