SR Oil Cooler for IO-540

Post by Al Paxhia » Sun Feb 19, 2012 10:44 am

My summer oil temps on floats are still higher than I want, so I am going to
add a second oil cooler. The plan is to mount it on the back of the rear
baffle. Has anyone mounted a cooler there and if so what make, model and
size cooler did you use? Do your cylinder temperatures run hotter on the
side with the cooler? Also a good source for purchase.
Thanks,
Al

Al,
Can you find 4" scat tube and flanges and uprate the flow to the cooler? If the cooler is large enough my guess is that you are not putting enough air through it. The 4" tube will flow about 78% more air.
