SnowSurfLax Posted September 21, 2007 Share Posted September 21, 2007 I know that you hardcore offroaders probably don't even care, but I've read that when a vehicle has a steep change in body direction (like our pathy's do) in the rear of a car that the wind creates a sort of vacuum behind the car at high speed that pulls it backwards and makes it less efficient. Now, some punk a$$ stole my spoiler right off my car (just slipped out the screws and walked off with it I presume) and I'm curious if this is hurting my gas mileage? Does anyone know if the rear spoiler on R50's helps deflect the air from creating a vacuum behind it? I know it helps keep the rear clean by deflecting dust and what not, but I also read how they recommend liitle widgets on the rear of SUV's to make vortexes to disturb the vacuum so that there's not a vacuum at high speed pulling it backwards. Does the optional spoiler do this or is it just for show? So any engineers out there have an opinion? Link to comment Share on other sites More sharing options...
Pezzy Posted September 21, 2007 Share Posted September 21, 2007 I'm curious if this is hurting my gas mileage? You tell us, how's your gas guage reading since the snipe? I put one on my truck (cuz it looks cool - how offroad savy is THAT... lol, and to keep the window clean) and never noticed any difference in mileage.

Not only does the rear spoiler help with that but it also gives you 25+hp and if you go fast enough you can even catch flight! Link to comment Share on other sites More sharing options...
navygz19 Posted September 22, 2007 Share Posted September 22, 2007 The spoiler/deflector deflects air downward so in essence it keeps rear spray while driving in the rain collecting on the rear window to a minimum. I'm STILL trying to get my hands on one... That said, I would venture to say it also increases drag to a point... Link to comment Share on other sites More sharing options...
jj big shoe Posted September 22, 2007 Share Posted September 22, 2007 the spoiler keeps the rear window clean?It's supposed to deflect air across the rear window and blow raindrops and such off as you drive. I think it works, but not so much that I'd notice if it weren't there. Link to comment Share on other sites More sharing options...
mikeysentra Posted September 22, 2007 Share Posted September 22, 2007 Mine seems to work, when I am going down a really dusty trail you can see the dirt that collects on the back window being blown off. Link to comment Share on other sites More sharing options...
SnowSurfLax Posted September 22, 2007 Author Share Posted September 22, 2007 No noticeable difference in gas mileage that I can see, assume it's more that I'm at 120K miles and difference in driving. Been a year or so since it got snatched. Rear window does get dirtier than it used to. Link to comment Share on other sites More sharing options...
FUELER Posted September 27, 2007 Share Posted September 27, 2007 Looked at some old pics.... this was actually my QX4's first trip to Baja, one month after I got her! i think i can see the wind action in this pic. ahhh.... the days when my QX4 was still fresh and unmolested.....

94extreme Posted September 27, 2007 Share Posted September 27, 2007 I know it helps keep the rear clean by deflecting dust and what not that's all it does... aerodynamics don't come into play at the speeds outr trucks go.. well, tiny bit maybe. lol Link to comment Share on other sites More sharing options...
FUELER Posted September 27, 2007 Share Posted September 27, 2007 (edited) haha, yeah it seems that my QX4 has about the same aerodynamics as a brick.... But it is well designed for minimal wind noise.... i made the mistake of installing window visors, unreal how much noise they add.

Simon Posted September 27, 2007 Share Posted September 27, 2007 That's true...the window visors do add to the wind noise, but they allow you to smoke while it's raining out and not drench your cigarette! Not to mention, you can leave your windows down a bit, and no one can see that you've done so. Link to comment Share on other sites More sharing options...

But yeah its nice to crack the windows in the rain Link to comment Share on other sites More sharing options...

FUELER Posted September 27, 2007 Share Posted September 27, 2007 (edited) these are the kind of blunts I smoke (music video) Edited September 27, 2007 by FUELER Link to comment Share on other sites More sharing options...
SnowSurfLax Posted September 28, 2007 Author Share Posted September 28, 2007 these are the kind of blunts I smoke (music video) That's not a blunt... That's a Smoke Stack! If you can smoke one of those on your own, you need a new drug. You're wasting too much money on that stuff to get your money's worth. That amount should have you passed out half way. Or you need to stop buying cheap $h|t. Link to comment Share on other sites More sharing options...
FUELER Posted September 28, 2007 Share Posted September 28, 2007 hahah no not the whole thing to the dome. You crazy. I just mean its the best method to smoke. The one in that video would be for like 2 or 3 people Link to comment Share on other sites More sharing options...
