clutch drive fans

A fan will not add HP. What they are saying is that a clutch fan can free up 15hp vs a normal fan.

If your car is a street car you should not use an electric water pump drive.

For example…. Take a 360 that makes 300hp without a fan at the rear wheels.

Put on a normal fan and test it again…. It will now be making less than 300 at the wheels (a loss of whatever it takes to drive the fan)…….

Now put on a clutch fan and test it again…. The engine will still be making under 300 at the wheels but the loss will be less than a standard fan.


What will never happen is a gain of 15hp……..


For example…

You test a 360 without a fan and it makes 300hp at the wheels……. Now you put on a clutch fan and test it again……

The power will be less not more than 300.
