    I would do the coolers. At least I did with mine. Used an engine oil thermostat to make sure the oil gets up to temperature.

    The guy at C&R encouraged me to run an external oil cooler in case of an engine failure sending stuff through the oil lines and integrated cooler, therefore ruining an expensive radiator.

    That sounds a little crazy to me. Mark Stielow runs integrated coolers in his C&R radiators and that’s good enough for me.

    I also ran the integrated coolers after discussion with C&R. They never attempted to talk me out of that (years ago, but still). We actually discussed the potential advantage of heating the oil up when I was street driving by having the water-to-oil cooler instead of just an air cool. On my original setup with an external cooler (air), I had to cover the cooler on the street to have the oil heat up enough. No thermostat though...

    Good point. I should point out that I've run 30 minute session full out at COTA in the summer heat at COTA with no cooling issues between the PS and OIL coolers in the C&R radiator. I did add a dry sump to the car to address other oiling issues, but with the C&R, cooling was not one of them! Very nice unit they make, and by packaging it to fit in the original location and space, it's easy to install and plumb...

    I too use a C&R with integral oil cooler. It was put in around 16 years ago before PS heat exchangers were popular. The next time the radiator comes out I'll add it.

    To reduce the chances of contaminating the oil cooler core a remote filter is used prior to the heat exchanger, hence protecting it from damage and clogging if something from the engine pukes out.

    I too tried running a Mocal thermostat but found that it had little affect. The thermostst bypasses enough through the cooler that the oil remains quite cold, enough so that the needle on the gauge does not move on cold days when street driving.

    I went the more complex route, for the sake of best possible cooling. Where I drive can be 120F for months during the summer, add that with open track days at a track in that environment (WSIR & BRP) and I wanted extreme cooling. I also plan on doing Power Tour, Drag Week, and several other bucket list items and I wanted cooling to be the last thing I have to worry about. I also don't compete and just plan on doing it for fun. All of my lines are routed inside my fenders so it keeps the engine bay still as clean as possible.

    I did just a C&R radiator with their best fans/shroud (have the flaps) and their recommended their 30lb cap. Of course, I have an overflow in case. I then added a stacked plate cooler for both the oil and power steering. They each have fans w/relays, filters just before the cooler, and are kicked on by thermal switches w/relays. The oil cooler of course has a thermostat as well. My C&R Spal fans and my Meziere EWP are run by a PWM controller. An EWP is a MUST!!!

    Doing this also means I'm not overtaxing the capabilities of the radiator by having to cool the engine oil and PS. This was a bit overkill for my existing 461ci Pontiac stroker, but I have a 535ci stroker coming from Butler next year I'm planning for. I do not have a cooler on my T56 magnum yet but will, same for the next Ford 9" center section I buy from GearFX. Lessons learned, but those will not have fans/wiring, just small stacked plate coolers.

    All of that said, if you are not in such a harsh environment and want to lessen complexity, by all means, do the integrated coolers.

    I'm in Arkansas summer. Lots of days 100-105. But again I'll be cruising. And couple times a year hit auto x and I'm planning a road Atlanta and a power tour trip as Bucket list. But being naturally aspirated LS7 and above uses, based on everyone's experience here on the forum it sounds like the integrated EOC and PSC on a C&R should do just fine

    I have an older version of the C&R with both coolers integrated. Its a really nice setup and works great.
