Look at Kenny Brown's Fluidyne radiator, it solved a lot of issues for me.

With the stock radiator the engine oil would reach 250 degrees, the Mishimoto rad issuperior to The OEM, 0.5" thicker and three core vs 2,..... and its a steal! Will be unloading all kinds of $$$ in this fix so I have to watch me pennies.

They have several available that fit in S197s. Did you get the FHP30x-302R-Hxf?

Is it single pass design?

The Mishimoto I quoted is a single pass I think....

I'd vote for the upgrade to one of the Fluidyne ones. JMO, but the triple pass designs will make a difference the next time you run an enduro.

EDIT: And I mean the $600ish one not the '302HX' type used on the 302R with the separate oil/water cooler at ~$1300.

Am liking my financial wounds as I tot up the damage.... But thinking that the oil cooler will be a must.... maybe that and the Mishimoto. with the 2013+ gt500 fan should leave me cool. Or no cooler and a double or triple pass rad??? Leaning towards the cooler.

Have to hide my credit card!! Grants coming!!

There is no hiding. :D

My feeling is if you stick with the Mishimoto radiator, that you should run a separate oil/air cooler (or two). Not less than a Setrab 948 or 172 in total capacity.

IF you plan on using the stock Boss oil/water cooler, then go for the triple pass Fluidyne and maybe a 934 or at least a 925.

JMO, but adequately cool the OIL. The radiator won't matter as much if the systems are split and there is no direct transfer of the heat load from oil to water.

Gotta protect the engine you just built.

No escape!! Would the Mishimoto oil kit fit the bill since it comes with all the hardware? Assuming I go with the Mishimoto rad and take out the OEM Boss oil heater?

I would go with a Setrab. Their quality is awesome. The Cool Tech package is a bit pricey but comes with the Setrab 172, brackets, fittings, and oil filter plate. And the 172 has lots less pressure loss than the Mishimoto and even the 9xx series Setrab coolers.

That is what I did. However, I may swap out the Setrab oil filter plate for the Mishimoto version because the M has sensor ports. Debating doing that because I'm nervous about drilling the plate. I tried an AN swivel fitting with s port but I wasn't comfortable with the sensor being so close to other things.

If you go with the 9xx series Setrab cooler I have a brand new bracket in black made by TMO's own 06mach1. For you, you can have it by just covering the shipping costs.

The OEM Boss cooler works and if you remove it you will at least need the 948. I know some refer to the OEM cooler derisively as an “oil heater,” but that is BS.

The 948 has a higher BTU capacity than the 172.

See BlackBoss and other posts concerning this subject, especially the CoolTech test threads, from several years ago.

When I installed the CoolTech 172 I ran it with the OEM Boss water to oil cooler per CoolTech recommendations. My oil temps with this combination ran 260 -275 depending on the weather and track.

When I removed the the OEM cooler and just ran the 172, my temps shot up close to 300. To get them back down close to the original OEM cooler and the 172, I had to add a 925 in series with the 172.

Now, I will state that my coolant temps are lower with the current setup.

I measure my oil temps pre-coolers. So I am tracking peak oil temps. If I measured them post cooler, which is what you get with some sandwich plates, the temps would look a lot lower.

Cool stuff. Thanks guys. Will go back and re-read the oil cooler setups. My current oil temps are usually around 250 to 275 with the OEM boss rad and cooler and Moroso oil pan. Will be needing a bigger oil cooler for the tranny as well. Working on a list

I run the Mishimoto oil coiler with a thermostated sandwich plate. You wouldn't need the t-stat since you are a dedicated track car. I know a lot of hard core guys swear by the Setrab stuff, but putting a heat exchanger in the proper position of the airflow has a greater effect on temperature differential than the brand of heat exchanger... in my humble non competative racer opinion.

No way, even if hell is cold.

This is great data and definitely supports some thermal estimates I made in the past...and others about running two oil coolers.

The Mishimoto oil cooler will not be enough even with the Boss cooler. And do not use the 172 solo. It wasn't the right lower limit in my previous post even with a better radiator.

then to run cooler than a car with the Boss cooler plus a 915 setrab, you might need an oil to air cooler capable of shedding about 110,000 to 120,000 BTU/hr.

Based on the comparable sizes you'd need to plumb two Mishimoto 25 row coolers to be adequate. One should be okay if you keep the stock Boss cooler and get the triple pass radiator.

One way or another, my minimum recommendations are about $300 more via cooler size or radiator type. I don't think this is an area to economize with your new engine and future plans for enduro racing.

@ArizonaBOSS , would you mind chiming in on your current radiator and it’s performance vs the FRPP unit it replaced?
When I had the FRPP radiator I didn't notice any cooling improvement vs. the OEM Boss radiator. With the C&R radiator, the coolant temps dropped about 20* in heavy-use conditions. It's not cheap but it works very well.
