Projects Overheating problem 33 chevy

That video also measured them all at like 5-6 grand where a lot of people are not spinning a motor that high anyways.

 

The video also used a thermo-clutch fan with no heat in front of it, should have picked the centrifugal
clutch and had the flow gauge in front of all four of them. They could have done an air flow and hp test at the same time.
At the speeds and rpm I drive at, the 6 blade solid fan doesn't seem to hurt the power, I need to get it out on a fuel mileage drive to know for sure. I can sure tell it pulls more air just watching the temp gauge.
