Interesting Observation on BRP Adjustable Air Deflectors

This morning while on my commute I changed the position of the BRP adjustable air deflectors to see how they would redirect air flow toward me. Well I got an unexpected result. :dontknow: When I flipped them back with the front end open, I did get more air flow along the sides of the Spyder toward the seat. But when I placed my hand up at the deflector I noticed the air flow across the engine compartment vent was causing more hot air to be 'sucked' out of the engine compartment. :hun: I think getting more heat out from under the Tupperware is a good thing but that means the air coming across my legs will be slightly warmer.

More observations are required.

I have run over 2700 miles so far after installing the adjustable air deflectors on my RTS. I have found that the biggest difference will be at highway speeds of 55 or 60 or more. It does provide more air to lower torso and thighs. When it is cool weather they do block the air for a more comfortable ride. I am still on the fence as to weather the mid position or the full tilt position makes much difference. Overall It is a plus for a cooler ride in warm weather and a warmer ride in cold without having to install and remove the old ones at seasonal changes. I give them a :thumbup:
I haven't really checked on the vents from engine bay having more or less air flow. I'll look into that.

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.
 
Another opinion

I just recently purchased a set. Best BRP accessory purchased yet! Being in FL they won't get set to closed very often. But to find out how they worked I closed them at 70 degrees on a ride and stopped in less then 10 miles. To hot! I have found half to be optimum for under 70/85. Full should work well for 85/95. 95/+ you wont find me riding but sitting in the AC. All numbers are in degrees F not MPH!

As a side benefit I am noticing cooler feet. But that remains to be an open topic at this time.
We have only ridden about 200 miles since installing them.

Bob, I too just purchased mine and have just about 300 miles. I'm not noticing a whole helluva lotta difference. However, I haven't been on any super slabs yet. My right foot is still burning up. Like some others the rubber is coming off the tennies. (2013 RT-S )

No ninety degree days here just yet :shocked:; but I am convinced that leaving them in the center position has improved my fuel economy... :thumbup:

Come on down......it's looking like we'll be going over 110 around the first of June.....once there......it'll be like that until October. Oh boy!! NOT!

Better gas mileage......that works for me. For sure nojoke :doorag:
 
I prefer just leaving them off- Better mileage-runs cooler!
We are going to have a "Heat Wave" in CT which means 3 days of 90 degree heat- Not sure you have that Term in the Deep South?
:dontknow:I know my brother in Alabama has High Heat and Humidity ALL summer.nojoke I prefer 40-50 Degrees with the thermal suit and bala clava under the helmet!!! :yes:

Luckily CT only averages about 21 90 Degree days all summer Thanks to the Canadien fronts that visit off and on thru the summer.
:pray:
 
I've got a lot of warm weather experience with them now. I'm not feeling the warmer air but that might be due to other mods. They work and are better than not having any deflector which is how I did last summer. I've also got the Bakers and I've played with each on and off. The Bakers put out a LOT more airflow.I Like having both since I'm in SW FL BUT if I could have only one, it would be the Bakers, hands down.
 
Had my 14k last month pulled the right pan off this weekend to see if i could improve on heat defection with spyderpops shields on noticed antifreeze & oil on it. Left it off took to dealer they're doing the H20 pump today. Driving to dealer without floor pan on made ALL difference think Ill leave it off. Any thoughts on this fix? :o

Might start a different thread with THIS issue. There might be others that would like to chime in and didn't because they don't have air deflectors.

I believe SPYDERPOPS recommends removing the plastic pans under the Spyder if installing his block off shields. Took mine off almost a year ago and they are still off...probably never to be installed again.
 
I have the adjustable deflectors, Baker Air Wings and SpyderPops plate and so far, the only time the heat is too bad is when stopped. One thing I do notice is if the deflector is turned in it really tends to blow up my t-shirt, causing my concealed .45 to be exposed. This is OK in GA but frowned on in FL ... :opps:
 
Just installed the deflectors. Don't find them as aesthetically pleasing as the fixed chrome. Closed they look like dumbo ears and they're moderately clumsy to operate.

They'll get tested tomorrow. It was still a hundred and one here at 7:30 PM tonight and that's about the time I'll be getting back tomorrow night. With no sun in the equation it should be a fair test.

Not worth the money for me

For me, the difference they make is very small and not worth the money. I've had them on during the colder months and now that its getting hot have had a chance to experiment with the 3 diff settings. It "seems" that i get slightly more flow on my feet with them closed...that is, pushed forward. Straight position seems to direct the air on the upper legs. Open all the way doesn't seem to do much of anything. But again, we all feel things differently; a buddy of mine has never had any complaints about hot foot, and his RT is box stock! He doesn't understand my fuss about it. :D
