Depends on how much HP you make???  If you make the 180 - 195 that I think you are making I don't think this cooler will work due to the added thickness you mentioned.  If you choose to try it anyway because of the good installation location (which seems like a pretty good tradeoff) you could use a C&R oil-to-water cooler as a 'fall-back plan' to get the additional oil cooling you need since your water temps are good and you have excess water cooling.  I have a 84 mazda water-to-oil cooler I'll loan you want to try it but I'm not to hopeful for this cooler to help.

 

Al G., does the C&R oil-to-water cooler seem like a reasonable supplementary cooling system to the Fluidyne oil cooler to you?

Yeah; I think so.  Having the two cooling systems coupled has some advantages, and can offset some of the imbalance we end up with. I had looked at going with both initially, but just didn’t like the complexity it introduced.  That will be my backup approach if my oil-air cooler doesn’t handle it.  

I also looked at just using oil–water cooler, until I learned that all the stock oil-water heat exchangers are made for piston engines, and couldn’t handle the flow rates of the rotary without excessive oil-side pressure drop.

As I recall, Fluidyne also makes some good oil-water coolers.  Does C&R make any of their own, or do they just sell the Setrab?
