<VV> My new experimental fan

Thanks Hugo!

This particular fan weighs nearly exactly 2lbs. If the shop that machined it had been able to cut it right exactly to my CAD model, it would have weighed 1.4 lbs, compared to the stock Magnesium fan weight of 1.2lbs. While it would have been nice for the fan to have been lighter, I'm certainly not complaining about the weight... this is a prototype, and fan weight is not a concern for me as this time. The output and efficiency are though and this fan is perfect for testing those attributes.

For what it is worth, if this fan had been made exactly to the model, but made from magnesium, it would

weigh around 11 ounces !

Looks nice - what does it weigh - that's the question?!

In 2013 I had posted that I was working on a new engine cooling fan, and I
thought you all might like to see

some pictures of the completed prototype that I will be installing on my
engine for testing. The expectations for this new fan are that it will
simultaneously crank out a lot more cfms, and use a lot less

hp... particularly at high rpms. I have been able to do some preliminary
tests that simulate pressures near

an engine rpm of 1000, both with the stock fan and the "Nashfan", and this
new fan does indeed appear to

be living up to my high expectations of it. I cant wait to see how this
thing does for real on a running engine!!
