Here goes my two cents again. In the late 60's early 70's, my daily driver was a big block '69 Camaro 396 cu. in, 375 factory under rated hp. It had 11: 1 compression, I installed a rowdy 7000rpm cam, motor idled 1100-1200rpm in gear shaking all over the place, 4:56 gears, total timing was 38 degrees, intimal timing fell in at around 18 degrees. Needless to say, this car had major cooling system issues. I solved the cooling problem as follows, I don't know if this would work on a 928 but here goes. The BB Chevy had a thermostat by pass hose from the intake to the water pump. The theory was during warm up the coolant would circulate in the motor avoiding hot spots etc. When the thermostat opened, coolant would go from the motor thru the radiator. BUT, BUT, BUT, some hot coolant still circulated thru the motor making things even hotter. My solution was to block off the thermostat by pass & drill four 1/4inch holes around a 160 degree thermostat. Now, all the coolant was forced to circulate thru the radiator. Granted though, it took a little longer for the motor to warm up. I also used a flex-a lite fan, I know, I know. This set up worked too well. I had to go to a 170 or 180 thermostat. As I said, I don't know if this would work with a 928, but it may be food for thought.
