Well I went back to our famed myth busting Dyno-Jet today we Mason-Dixon TDC members call "The Humbler".Its called that because it makes no claims and takes those who makes those claims weak with fear.
Today's runs were done in the same mode as the last recent runs on my truck at our clubs Spring Fling event.The correction factor was the same and the only difference was a minor elevation of humidity with the storms rolling through.I had the same injectors,same intake,same fuel pump so nothing was different mechanically.
At any rate off the Dyno-Jet today my truck had a increase of 7.67hp and 26.34tq over what was made at the spring show.I had a best run there of 478.61hp/981.92tq at the spring show and todays numbers were 486.28hp/1008.26tq.So what did I learn today,they must have made their 26hp gains on something other than a heavily fueled 12v.
My fuel milage gain has been at 3.1 mpg doing my normal driving which is a combined city and highway conditions.The truck had been averaging 16.93mpg and now the last two tanks have been over 20.....Andy

I do not hear them running at all inside the truck.They are set at the factory preset temps and when they come on they come on in stages first 65% then ten more degree increase they come on at 100%.You can also wire a direct full time 100% on switch for inside if you need them.On the dyno today they never ran and when driving they only came on when I crossed Blue Ridge Summit and the only reason I knew they come on was I seen it on my digital volt gauge.As for the charging system hating me,I had already made provisions for that because of the fans and FASS pump.I contacted "Mean Green" and got one of their 205amp units and installed it.Too much fuel system,fans and a desired stereo upgrade will mean problems which was why I did it.I will add a link to them below for you.

So far so good but I do not see the heat you will see in Texas.I am planning a trip later this year to see a friend down near Austin and can't wait to see what happens then.

I think flex fans have a place,just not in or on our trucks.I used one on my drag car for years with the electric water pump and had great results.On our trucks I will agree that they have no place.

I can not answer that but know the Flex-A-Lites move more air than that,however its not my truck your working on.
