Thanks Harry. Hope it's inspired you to do something DIY too

I should have known better when I started this project;
I dealt with engine cooling systems for nearly 25 years and have always known that a puller fan is more efficient than a pusher
That and I shouldn't have trusted the flow #s I read on the web for 4" ducting

Anyway, 'tis all good now
