Evolution Two Cooling Fan   Price: 199
Having developed the Evolution Two cooling system, I have also brought just the fan and inlet/backing plate to the market for OEM and aftermarket fan shrouds.

Innovative dual inlet fan that is 81% lighter than OEM fans (doghouse and early vw).

Versions available for doghouse, '71 and later, and non-doghouse, pre-'71 fan shrouds.

The early VW fan shroud version flows 25%+ more air than the OEM fan.

The late VW, doghouse fan shroud version flows 22%+ more air than the OEM fan.

You can see the airflow and horsepower draw figures in my blog posts here:



You get even better throttle response than the original lightweight cooling fan that I introduced back in 2020 as it's another 8% lighter, plus even greater airflow capabilities, along with a much improved mounting system (more like the way a flywheel mounts) that won't run out, and again I tested to 8,000 RPM, just like the original lightweight cooling fan.

Two fans are better than one!

If you don't get the reference take a close look at the fan design, and the inlet that replaces the backing plate, and you'll understand what I mean.

Just like the Evolution Two cooling system, this comes with options for various throttle linkages, and should work for pretty much any linkage that is out there. The inlet is very low profile so that it stays out of the way.

It also comes with an option for generator support, and not just alternators. So, for you generator lovers out there, this product will finally work for you too! Only generators that are 104 mm in diameter are supported. That should be from the 40 hp engines up, as the 36 hp engines used a much smaller 90 mm diameter generator.

Generator support does cost more, as I had to beef up the inlet because generators are a lot heavier than alternators.
