They work, it's been proven in wind tunnel testing from the days of the legendary Porsche 917 testing at leMans in the 60's where these cars would routinely go well over 215 mph...they are not a new concept...BUT the trick is the faster you go the better they work for you...so on a racecar, say an open cockpit prototype, GT, or Touring car they can help significantly especially for high speed stability and increasing aero grip...or dynamic load on the chassis in applicable areas. You got to be going really fast to get your money's worth and the faster you go the further your dollar will go, and the more slippery the chassis to begin with the more positive effect these will have on your handling and aero package. An added benefit would be better fuel economy but I don't know if that would be a significant increase... again, depends on slip stream, chassis design, vortex generator placement, air density...and a host of other factors. One thing these would do is really help in the rain to keep the water moving faster around the vehicle and less water on the vehicle near the boundry layer, where laminar flow would exist in close to the body.
This said it would be interesting to try these (but there are better ways to create efficiencies on a boxy chassis truck), a fun expiriment to see what happens. Our trucks are like a brick passing through air so it would be interesting to see if there were some benefits from aero improvements at nominal speeds like hwy around 60-70 mph...

they say 3 per foot and there 2.50 ea. i was thinking on the top of my cab and down the side until the bed rails. to try and cut down the wind going in my bed without using a bed cover and turbulence behind the truck. it cant hurt. lol
#693
would help more the faster you went and the more your on the hwy over say city or around town driving...
how many would our trucks take? Top of the cab and down the side to the bedrails...like you planned.

im guessin like maybe 30 at the most which is $75 plus whatever shipping is they come in black and white. i was going to paint my faded grey/brown like my truck. lol
edit- it would take 24 for top of cab and downt he sides so i might just buy 30 and have 6 left for the hood. also im thinking a 2-4 drop. doing the 2 first to see how it is then the 4

yeah I was thinking like 28...6 ft across the cab (right?) at 3 per linear foot...plus 5 on each side going down on the side of the cab to the bedrail...even further down to the molding break may add another 4 -5/side...
in your sig the mods of lowering the truck and shaving weight will help you a bit...but I think the limiting factor will always be the shape of the vehicle, even making it slightly more efficient through the slip steam with small incremental improvements will get harder and harder...you have 2wd, manual trans w/GV overdrive so you're already way ahead on the efficiency curve...

wow...i dont even know what to say
also you dont need a bed cover to prevent drag on the bed...ever seen a wind tunnel test of a pick-up and the positive air pressure bubble in the bed?
