The only time my miata has ever started to overheat- numerous track days at
Mid-Ohio, autox's, full day hard driving- was when I took it across the country
and stopped by FM. Going thru those elevated highways and long boost time.
Looks like I'll be in the area for the Open House, are rental cars allowed
Bill?

I understand that. But typically Miatas aren't great at transferring heat from
their rads to the air. There comes a point where everything is just heat
soaked. Not such an issue for flatlanders, but here in the land of no air
density, 100 degrees and no humidity it makes life difficult.

But the more heat you transfer to the coolant from the block the more heat is
leaving the block. A higher delta T at the radiator means more heat transfer
occurs there. Think of it as heat flow and not temperature. The more heat you
can carry away form the block via transferring it to the coolant the better off
you are at maintaining thermal stability under high load.
I would still run a separate oil cooler as well though.

I've fallen on my sword already for my typo, yes, the oil heat would be going
into the coolant. Which is usually already overloaded trying to get rid of
heat. Better to offer it another path to dump heat to the air without involving
the poor radiator.

I think you mean the oil will be dumping extra heat into the coolant. But I
don't under stand how that can be a bad thing. One more way for heat from the
engine to get extracted from the engine and sent to the heat exchanger
resulting in more heat rejection.
I would guess the amount of coolant flow through it is on the low side though.
the B6 and BPT GTX's have a cooler that is twice as big and run the full flow
headed for the heater core through it.

I think Keith is correct in its reason for being, but once on track your oil
typically will be hotter than your coolant, so the cooler will be dumping a lot
of extra heat into the oil that would be better addressed with a separate
oil/air cooler.

Yep. That was my hunch. I’d hope that my oil temps are not exceeding the
coolant temps. Hopefully I’ll be down around 200-215 on the track now.

My suspicion is that the stock oil "cooler" is actually there to aid the oil in
coming up to temperature more quickly. The coolant reaches operating
temperature before the oil does.

Does anyone know how much cooling the stock oil cooler actually does? I’m in
the process of wrapping up a cooling system re-route and had decided to
disconnect the stock oil cooler/throttle body heater circuit. Given that I was
seeing 225 degree coolant temps on the track pretty regularly, I’d think that
the oil cooler would be doing more heating than cooling. However, since I
don’t yet have an oil temp gauge, I don’t know what my oil temps are.
Thoughts?
Thanks!
Shaun
