What a POC that airdam is! I kept dragging it on low parking curbs and a few times on steep driveway transitions. Who would install that with top down hardware????
However, I immediately noticed a lack of rumble air turbulence, and it seemed so much more quiet. I did 10 runs to work at exactly 65 mph and recorded both trip mpg as well as instantaneous MPG at certain points and there was no difference with the air dam removed. Maybe over a 20 mile trip, it might give you a slight increase in mpg but I could not see it. I also put a string on the lower air ducts under the truck...they appear to draw air from the road and angle it up. I used my front camera to view it at 65 mph and you could clearly see the string take on a characteristic shape. With the airdam off, the string appeared to be showing more air flow...which makes sense. So lets think about this. Taking hot road air and blowing it up into your engine..... Not sure where the air goes. MAybe just to the lower exhaust header, then back out? But it appeared to show more flow...of hot air into the engine. Maybe this is why people are seeing hotter engine temps?????
I have access to a full blown aerospace flow meters with thermocouples and the whole deal.....but there is no freggin way I will put that air dam back on....even if its in the name of science.
