Rebadge has asked me to take a video of this for their records. ideally, I'd like to hope that by placing these on the rear of the van will help with some cross winds and better air flow. I'm not hoping for better fuel savings.. but we will see. Installing the front air dam maybe a hindrance instead of helping we'll see on that also. just think these things look better and not as noticeable as the things on the turner cars..

had a concern this morning. I was thinking the rebadge guy made just 23 stickers.. so I sent an email just to confirm.. he sent this pic back.. confirming he made "23 set" of these sticker winglets. These were shipped yesterday and should be here Fri.. and with nice weather coming up. I'll have a chance to get that view and photos of the winglets on the van.

The wing worms arrived on time and carefully packaged. I was under the impression these would have bene in a larger box.. but there's 23 sets in a small USPS mailer box.. not to get to work on mounting half of these on one side of the van and doing the pressure washer spray test.. just to see if these divert any air flow. Even if there's no or not much air being diverted, I'll still use these on the van.

stay tuned for the spray test along with photos of these on the van.

I can't say that this was a "big" success, but when spraying the water down the side of the van, I could see a difference in the flow stream of water.. the video we shot did not pick up much and when we slow the video down. I can see these vortex working to some degree. We're not disappointed, and we went ahead to placed all of the wing worms on the van were we needed them. The roof top shot, reminds me of those "things" tuners are using on their cars placed right before the rear window. maybe these things will work for others, but our van is designed too much like a brick for these things to actually work like they should.

...but when spraying the water down the side of the van, I could see a difference in the flow stream of water,,,

Pix don't disclose the flow of the water, but it's not a good test in any case; due to the relative mass of air and water.

Maybe try a lot of small tufts around one or two (or two or four?) wing worms and a leaf blower.
