The wing and carbon fiber are on

[altonk]

I just finished installing the wing and am about to take it for a spin

Sorry about the poor picture quality but it's dark

Better pics tomorrow

:yikes: WOW thats some wing.Nice job :thumbup:.Looks cool.

[altonk]

It's the nose wing from a mini sprint car
More a spoiler than a wing really

[BajaRon]

I thought wings were negitive (upside down) air foils?

I don't know man...

I think a wind tunnel is in order here. I just imagine that there is enough turbulent air coming off your body that the wing won't do much good.

I know I chimed in before, but wings do their jobs at high rates of speeds, and I doubt this will help you in twisties, maybe some fast sweepers...

Maybe you could rig a leaf blower and a smoke bomb and film it... Might give you a rough idea of what is going on. Until then, What you are doing is indeed interesting.

If the aerodynamics don't work ... It looks like a good sand and gravel carrier :roflblack:

But Alton ... bro ... Something don't look right. It looks like it's going to push down on the back and make the front end light. When you told me about it, I'd envisioned something small, thin and discreet ... angled more flat and tuned to do something you want. Plus the rivets mmmdunno. I would be very careful at high speed with dat tang. The rest of the Spyder ... all that carbon fiber ... looks outtasite!

[altonk]

Gonna put some sailing tell tails on it and attach my helmet cam to the backrest. I'm curious too

But it does look cool I think

[altonk]

Riivets and aluminum are tough stuff
Racing old school,
it took me all afternoon and evening to put that together it was a kit of bent metal and a bags of rivets

Later I'm gonna replace the endplates with carbon fiber

[altonk]

Oh btw Paul already took it for a triple digit spin on I270 and it's stable

And it didn't blow off :ohyea:

[altonk]

I saw that but my tires won't fit in it

I am thinking about a front splitter out of carbon fiber sheet though

Apr performance will cut you one if you send them a template

And it's cheaper than the fiberglass from those guys

I sort of agree here. I had something else envisioned as well. Don't get me wrong; it's interesting and well put together for sure. I imagined "some" downforce benefit to the new wing but this ieems like it's really going to push down on the back. As far as cornering, jury is out. You'll have to keep us posted for sure. How much does it weigh? I know the turbo offsets alot of these things, so in the mean time until you have had some seat time we can arm-chair crew chief all day! I sure will be interested in how things go. Looks sick though man! :2thumbs:

[altonk]

I hope it does really push down on the back that's why it's there :yes:

The small wings you see on street cars are just bling

I know this will generate down force because I could see a difference on my micro sprint running a wing this size when I raced them.

It's a bit draggy and is set at 22 degree angle of attack

[altonk]

Btw it weighs 6 pounds including struts

[Raptor]

You'll be able to trim it out once you get a taste of what it does and what it wants. Or what you want!! So go forth and shred. We will eargerly await your findings! ANd again congrats on making it happen! :2thumbs:

[scudrunner]

I have to agree with SilverSurfer here... looks like the moment arm is too far out causing a pivit point at the tire instead of down force. In otherwords, the down force is too far aft and not over the wheel. So instead of holding the back wheel down, it is creating a fulcrum point at the back wheel and lifting the front wheels up. Of course at the speeds we are talking about, it may not be much.

[altonk]

I put it out there because of that
Without a lot of force putting it there gives more mechanical advantage
If it made 2 or 3 hundred pounds plus I would have moved it in

I rode it into the city and on the expressway and george Washington parkway
The rear is much more stable now and I can feel the suspension compress at speed so I believe it's working

[bcspyder]

:dontknow::dontknow::dontknow:

I have to agree with some of the others. You have done a great job already with the tire/wheel package and of course, the motor. But the Spyder has a unique stance and attitude, and was created with appropriate proportions and flowing angles and curves. Sure we add a few cosmetics, but with the exception of the front fenders/wheel combo, BRP got it right I think. You have obviously taken care of the fender problem!

If you look at custom cars and other quality vehicles, every build starts with a great stance.
I think the wing takes away from that in it's current form. The wing seems out of proportion and would probably not provide enough benefit to justify/offset the oversize look, IMHO. Even if the wing were to add significant downforce is it "fixing" a problem?? Haven't noticed any loss of high speed traction in the rear myself, and if I wanted to add downforce I would be looking at the front.

[SilverSurfer]

Whoohoo! Well, so far so good Alton. Triple-digit spin? between that aero charger and the Wing, I imagine something akin to this (The music is as important as the imagery):

You did a great job with the wing and the wing looks good but Sorry Bro . Put it back on the sprint car .:dontknow:

[altonk]

BC,
I didn't do it for astethics.
If you drive it to the limit you'll find that it is constantly in oversteer.
The wing seems to help some.
I'm going to pretty up the wing a bit with radiuses on the endplates when I build them from carbon fiber
The pictures make the wing look larger

If I get this right you won't be able to see me long enough to tell if it's pretty as I pass you :yes:

[altonk]

They already know me

[YPILOT]

Alton, You are the pioneer here. :clap:Seems that the end plates would generate a good amount of side force which would be a good thing on the long sweeping curves. I think that is what you wanted to achieve to keep the back end in line, right. The Carbon fiber fender and sport shield look great. You've got the pro street thing going, pretty cool. Besides if you carry a passenger they will have a place to nap! Keep up the good work. Dennis

[altonk]

It's a work in progress I'll clean up the wing esthetics after I get it tweaked performance wise
They'll be carbon fiber and rounder to match the look of the bike but you gotta start somewhere

[Lamonster]

Makes you wonder why these never went on to a longer production run other than a cost issue and the fact that they need to be out just a tad more to be more effective.

But still, it's cool to see people push the envelope! Keep going Altonk! Yer doing great!

[Eraser]

I see it's been a drinking weekend.lol

But true "Genius" can EVOLVE from a drinking week-end! I don't like the look of it but I like your thinking on this.I'm going to view this as your proto-type and I'm looking forward to seeing where it goes.:2thumbs:

[altonk]

It seems people either think it's cool or really don't like the way it looks

I ordered wing rev 2.0 today. same size, better airfoil design

I am having the end plates radiused to give it a rounder look to match the bike and having the whole wing powder coated black.

The full airfoil design should give more downforce as opposed to the current spoiler design.

The downforce is noticable, I can feel the rear end squat some at speed and it takes more throttle to break the rear tire loose.

I'm gonna try to get some more quantitative data this weekend.

I also am going to lower the handlebars a bit more to get my upper body further down and out of the airstream

If nothing else, its a place to display all the show trophies (or park the beer cans!)

New hood art

[SSG Bean]

Although I absolutely hate the 2 fast, 2 rediculous looking wing, the carbon hood looks great!

[altonk]

Hey I don't like chrome
But to each his own

[altonk]

Now if i would have hung a keg of beer off the back for down force lots would like it

[SilverSurfer]

Its bound to Get the Attention of the Friendly Police Force in your area?

Maybe the Air Force :ohyea:

[boborgera]

For some reason that wing brings back memories of the Flying Nun.
It is cool looking though,
Then again i liked the way the Edsel looked.:thumbup:

[altonk]

Thanks,
There are tons of wings around but most are too wide 45" plus and are designed for a wide mount

This is why I went with the sprint car nose wing they are also designed to make downforce at lower speeds

[Lamonster]

Having seen wind tunnel smoke test on motorcycles I can't see how there will be any benefit to having a wing on the Spyder. If you like it that's all that matters. :doorag:

WHY?

[altonk]

Why the wing?
The spyder is light in the rear and oversteers

[crtravelnmore]

The hell with the wing, just get the car! It will blow away anything you put on the track next to it.:D

You know, I was thinking that! That is one bad-@ss ride. But we are Spyder people. There be Spyders here! :D

So Alton, how is the new wing coming? Have you received parts and stuff yet? I am still interested in your journey!

[altonk]

Should be here by the end of the week

:thumbup: Looks good powder coated . But once again put it back on the sprint car . The concept is good and if you where to take it to the track I.m sure it would improve your quarter mile or your oval time but to drive around on the highway, how fast do you need to go ?

But then again if we didn't mod our bikes they would all be the same except the colors. Thanks for the time ,effort and pics. Keep modding Bro !

[boborgera]

:shemademe_smilie::D

[SpyderDog65]

OMG You are a Dork that's soooo funny lol :-))

[altonk]

Pretty much the same outside dimensions just a better airfoil powder coating and radiused end plates

[altonk]

Ok so the wing is on,
I'm happy with the airfoil and the mount. It's not stiff enough but my son in law works at a high tech composite shop so soon it will be cast in carbon fiber.
From my calculations by monitoring speed and rear shock deflection I'm getting about forty-five pounds of downforce at eighty miles per hour.

That's about average max entry speed under max braking for me.

It doesn't sound like much but the center of pressure is pretty far back adding some mechanical advantage without raising the center of gravity

With the brake bias set to babe on board mode gives you more rear bias but the fronts still stutter first.


So what's next

I'm home for the summer on a much needed sabbatical and my parents have a full sheet metal shop.

I thinking the undertray is next
I'll order the carbon fiber bumper and will have a structural place to mount the tray.

The problem with putting an airfoil underneath is clearance

I'm toying with the idea of scrubbing rubber curtains McClaren style

Self inflating with steel drag strips
If I make them retract when deflated I can put a pressure relief valve on them and make them cockpit controllable.

You sir are truly a mad scientist, but I like it! :2thumbs:

Of course some updated pictures will be required once you have something permanent to show us.

The wing definitely takes away from the look of your bike. The other mods? Cool. The wing? Not so much.

I think these wings should be left for the tuner crowd not the spyder crowd. If you really really want a wing, it should almost be a molded piece that blends into the tail piece of the back bodywork.

[altonk]

Aesthetics aren't what it was about but I like the way it looks and I'm the only one that counts :)

I did it for handling and it helps there.

[altonk]

And I'm not really interested in being labeled as part of a " crowd" I'm just fine standing here in the corner alone

Each owner should mod their Spyder to their liking and not worry about what anyone else thinks. If others like the finished product, then that should be considered a bonus. :thumbup:

Thanks for the updated picture.

Sensitive or what !!

I was not labelling anyone. Wow!! Just meant to say that I did not think the wing is really for the spyder. Can people not express an opinion here? You are right ... your the only one that counts as far as the look of your bike goes. I did say that I liked many of the mods you did. You know what? WHATEVER.

[altonk]

Dude we where chatting about wings and such you started in about crowds. I'd rather see the wing on a street legal F1 but I can't afford it. This little experiment of mine has nothing to do with looks or demographics

[Idaspud]

Not my taste but if you like it is all that counts, with that said some people don't like the looks of my RT and thats fine, I do and that is what counts to me.:yes:

What are you doing that for? Anyway, put some solar panels on it and make it something functional!

[mooneych]

I actually think it looks good; if it also improves handling, then you are in the bonus round. Please remember that the machine we are discussing has nothing to do with what you are riding, and is not for the faint of heart. nojoke

[Smokinspyder]

Now i understand downforce and all that with these wings ... WOW thats all i can say its definately different and it may not be my cup of tea the time and imagination to add anything to your ride ( spyder or not ) deserves credit ... I dont know if it really would do anyhting its its kinda neat looking !!!! :2thumbs:

[Ga Blue Knight]

I was wondering how long it would take to bake a dozen biscuits with that thing!:D. Just kidding looks very sporty and no doubt helps at high speeds

[Motavar]

For the amount of times I've been up on two wheels the wing sounds like a good idea.
