• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Interesting Observation on BRP Adjustable Air Deflectors

Adjustable Air Wings

Ride report.

Wind wings in position two - first click open. FYI - this test and future testing will go like this. Wings in one position the entire ride. Then the next entire ride in another position in similar conditions. This should make differences in settings obvious. At least that's my thinking and the way I will proceed.

Return time and route had to be altered. Back seater (pillion) was struck with altitude sickness. More to it than that but won't go into details. Other than to say....if you have any kind of heart issues you take med's for. Understand they're likely not going to protect you quite as well at altitude. Just a tip. In the end she's fine and a trooper for sure. Flexibility and road trips should always go hand in hand. It's about the journey.

Ended up logging about three hundred miles for the day(even with extended down time for her) but, it was near midnight before we got back to the desert, and the temp gauge under the hood was only reading 91 degrees. It was hotter than that at 7:30 AM when we left.....98 degrees.

What I did notice. Deflectors in the mid position do an excellent job of putting air directly on my knees(may, or may not, be the same for you - my saddle is two inches taller than stock and I have a 34" inseam). More air on the knees is a good thing. In the past(in hot conditions) I've often had the sensation a magnifying glass was focused on my knees. Knee hot spots should not be a problem going forward. That's great!

Passenger noticed nothing reportable - positive or negative, about air flow from the deflectors. That said, there are so many variables that could come into play here. How high/low the windshield is being one of them. More testing needs to be done, and will be doing that on future rides.

Of note. Some have mentioned that hot air was being siphoned up from the exhaust vent just under and behind the deflectors. Seems to be a valid observation. Tho until tested in real heat won't know if it's a big deal?

Personal opinion.

Had it been myself who asked engineering to redesign the wind deflectors, I'd have asked them to incorporate a ram air intake for the upper out flow vents(both sides). At speed the scoops would force cooler air into the engine compartment and still allow air to escape when setting still.

To be continued.

I have that magnifying glass feeling but a little higher up and so much so that my skin will be red. Did you feel any difference on your thighs?

Thanks for the write up and I'm looking forward to your test reports from all of the positions.

Hard to know, it's such a personal thing. But, here's my thinking. Your hip rotation is most likely more than mine, meaning your thighs are not level but sloping horizontally from hip to knee. If so, I do think they will help because they should flow air across that area when in position two. At least I hope they will do that for you :thumbup:
 
A couple of notes:

a) I had them installed on my RT-S 2013 out the dealer, so comparing it to my old 2010 RT... BIG AIRFLOW DIFFERENCE!! Especially with the heat coming out of the right side. Put Spyderpops block plate, and I feel it once in a while (I think it's the Cat coverter coming from the seat), but nothing that I am suffering from melting shoes. But opened in hot weather, I feel a nice breeze, closed in cold weather, keeps the breeze away. 3 postions, works for me!

b) There is also the Baker Wings that some :spyder2: owners swear by them... might want to consider those. But IMPO they are more sailboat sails than BRP's Dumbo Ears.

Considered the new Baker wings that attach to the water deflectors(no interest in the FULL SAIL VERSION). Requested additional pic's when he posted about them, but he never responded. So, I didn't buy. Simple enough.

If anyone has installed them - stand alone - I'd really like to hear a report and see pictures.
 
I think you will find that you also suck hot air out of the body vents with the deflectors set straight back (middle position). That air is channeled past your legs, but the passenger may get it.


This is an absolute fact! Straight back you will experience more hot air blowing back on you. If moving at speeds above 30mph I have experienced temperature drops of 3 to 5 degrees under the tupperware.
 
Another effect of adjusting the Air Deflectors....

Since I replaced the oem Airbox with the Kewl Metal Intake kit, I have experimented with ways to reduce the high-temps under the tupperware, mainly as it affects engine Intake air temp.

Playing with the BRP adjustable Air Deflectors is one approach I have found useful to reduce the heat levels and improve the airflow around the engine....

Setting the Deflectors to a different adjustment on each side creates an imbalance in the air flow and pushes more air through the engine compartment, depending on the speed. I have been able to lower the temp near the Intake by several degrees by closing the vent on the left side and opening the right side when running at highway speeds... At lower speeds it doesnt seem to make as much difference.

but, you will only see the difference if you have a temp sensor under the tupperware (as I do)... all of this has little effect on rider comfort and rh hot foot... but should be of interest to those who have removed the oem airbox.

Who have you been talking to?

Down South; they call three days in the nineties, "A cool spell... :shocked:"! :roflblack:

Quite contrare Sir! Three days of 90+ degree days is a hot spell especially on the Atlantic coast side over at the Gulf coast they refer to them as "hot hot day."



It won't be long until you guys in the cold frigid north will be packing your bags to fly south.
