After hours of reading the past threads on the subject, and not completely competent in this decision, what is the largest cooler that will fit on the rear baffle of the 7a, and is the dual pass more efficient? Engine is the angle valve 200 HP with piston sprayers. I originally installed the 8 row that was in the Mooney that this engine came out of, but I don't think it is going to cool enough. Other data is a non modified James long cowl, custom plenum and diffusers, two exhaust pipes out the bottom. some have said trimming the cowl exit worked, and some didn't, some have too cool oil temps???? some did louvers and or ASA cowl flap and some had good results and some didn't. thanks for any input, Bret.
