Ordered Airtabs today!

[jeffreymccoy]

on my truck. I imagine it has a greater impact on the shape of a truck / van than it would on an already much more aero car.

First - the scale pics, as requested:

















Then - pics of them installed on the F150 (I may take the time to paint them red later - but most likely not.)












Finally the stats on the test route...that being a 45/55 mph bypass stretch with stoplights out, a 65 mph interstate out, 65 mph interstate back, and 45/55 mph bypass back.

Before (all current mods except Airtabs), according to SGII
23.6 / 22.6 / 20.6 / 23.7

After airtabs installed, according to SGII
25.7 / 24.3 / 22.0 / 25.6

Appears to be a solid 2 mpg gain (7-9% increase).... It was also pretty cool to "see" them working. I drove under a falling leaf. It would normally have hit my windshield and bounced over. Today, I saw it falling and then get rushed up over the windshield without ever hitting it, so it would appear that the tabs on the hood are indeed directing airflow over the windshield to some extent. Granted, this was one lousy leaf... it will be interesting to see if this trend continues (lots of falling leaves this time of year), and if I have the same experience noted by the other guy - a cleaner windshield...

Cheers

Now that's what I call just diving in! Wondering where you got the idea for using the tabs on the hood?
