I think it works quite well. But make absopositively sure that it's rated for the oil pressure you're running. Years ago I had an oil cooler put into the custom radiator I was having made. Ran great for 1 3/4 seasons. Then I blew the engine halfway through the last race of the season. Had a Prod friend with the same experience. I'll never pipe oil to the radiator again.

thats all we've ever run , it came from ISC racing in florida . mike offered the radiator & exchanger & oil lines as a kit. rarely does the car run hot . we also still use the stock type oil cooler to cool the oil just before it goes back into the engine. we believe this works well ! ralph
