Those early trombone coolers were a joke. When they switched to the later carrera cooler in mid to late 80s they worked extremely well and needed a thermostat. Eventually the displacement reached the need for 2 carrera style coolers in the fenders in the 964/993. I have seen alot of
oil bypass mods and thermostat mods allowing full flow but usually extra precautions were taken on oil selection.
