A couple of pics of a beefed up rear baffle installation for my new RV8.
This is an 8 row cooler from Pacific Oil Cooler Service. It's an Aero Classic HE series #8001599.
We are running this Cooler on our current RV8s and are very pleased with it.
We switched from the Stewart Warner 8406 (or 8604?) to the 1599 because we were seeing oil temps approaching 240 degrees during our air shows.
Now on a hot 95 degree day, running full throttle, 2900 rpms, for nearly 15 minutes, we might see 205 degrees. CHTs. 380 -400.
