I have come to the conclusion that I will sell my SW8432R cooler and purchase a SW8406R and install on the baffle. The firewall would be ideal but the configuration of the TD motor mount and what I already have on the firewall. Thanks for the ideas.
The RV7 I purcased with IO-375 has no oil cooling problems. The builder indicated that cooling was a problem and was solved by remotely mounting cooler. My suspicion is a lack of differential pressure. Letting the wright amount of air needs to be balance with the wright amount out. I am building stainless cowl Louvers to increase outflow from the cowl thus increase differential pressures. Adding the Louvers was also done to improve effectiveness of Pmag blast tubes. CHT's also appear more even. The bigger picture may be worth looking at.
whatever you do make sure it is 4 inch Scat tube. My 7 has 195 hp with piston squirters and i fought high oil temps for a long time. mine is 10.5 to 1 and I also fly near Sacramento. 3 inch was not even close to adequate or was the stock cooler. I also have a Sam James plenum so that makes it even harder to keep the temps down
