With the French-Air-Brakes on 36.702 mpg (CDN) temperatures warmer air on all the way.
With French-Air-Brakes removed 40.055 mpg (CDN) even hotter temperatures and air on all the way.
Well that was a very interesting and counter productive experiment.
I will be skirtless from now on. |
My thought is that the skirts could not effect the mpg by more than 1 1/2 %,as this is what is claimed by the folks with the PhDs that researched them.And this would be a difficult thing at best to nail down,without the aid of a wind tunnel.There can be so many variables when doing on-road testing!My recommendation is to hold onto them a while longer and see what your results are like with a greater history on the car.Also,should you do future mods to the back of the car,the skirts would be part of a comprehensive package.50% of your drag is still behind the car.The skirts look great,you've got alot invested in them,and in so many ways.Consider a little more running time before you toss 'em.I struggled an entire winter with the bellypan on the T-100,only to be finally rewarded once things warmed up in the Spring.It was a long frustrating wait but the 2-mpg was worth it.
