(I also tried a Hayden Severe Duty Fan Clutch and it also kept temps up around 200°F all the time.)

Photo #2:

+100°F day 75 mph with 7 blade Lincoln flex fan

(The car will not ever get any hotter than this, even in traffic, verified by mechanical guage and ray gun.)


Note reduction in oil pressure in photo #2....Robert

Not to rain on your parade, but that's no big deal because you're not running a/c. I run a non thermal clutch in my 72 Formula with a/c. Without the air on, the car will run 170. With the air on and in traffic, it'll get to 210.
