I thought I accidentally erased my original post

I was wondering out loud if a removable wing (secured by clamping on the trunk) would help in traction during high speed runs at say autoX or racing. some people barfed (hahahahahaha) like I expected, some people asked some good questions, and here's what I have so far:

Why not clean up the underside of the car, add a splitter on the front and a diffuser on the rear. Then you can have down force without a big wing.
Plus you would have less drag than what a wing generates.
To get a wing big enough and with enough angle on it to create downforce at the speeds our car will do you will have a lot of drag. And if you don't add something to the front of the car you could cause lift at the front. Just ask some Porsche owners that have put big wings on the rear and nothing on the front.

 

Mingster-

The Mugen front lip spoiler includes an underbody tray that extends to the rear of the front suspension arms.

Take a look at that one too. That may or may not help you. I would be careful changing the aerodynamics of the underbody since it can change the cooling of the engine, transmission, and rear differential housing.

I love it!

I've been thinking about this for a while...its good that at least one of us is considering going through with it.

For the rear section, check the feels carbon fiber rear diffuser, already been done. For the front, GTR was on the money Mugen's done it. Center..no one has done that yet.

I've been talking with my engineer about greating a body kit, along with a flat underbody tray (like your saying), that as a whole would combine techniques outlawed in F1 due to their effectiveness in creating extreme downforce (outlawed because it would allow the cars to corner too fast, causing saftey issues).

Well, keep us updated...

Mingster,

I question the need for this particular piece of equipment. I've had my car over 100 MPH on the racetrack and never felt I needed additonal downforce. I also know someone who had his S2K over 120 MPH at Willow Springs and he didn't mention the car feeling light. I don't think our car has the power to attain much higher speeds than that on most race tracks because the straights end. From what I understand Autocross is generally at much lower speeds than a typical racetrack so Autocross shouldn't require it. Has there been anyone who felt the car was unstable at high speeds and needs this? I'm not trying to rain on your parade; I'm just doubtful as to the need for this type of equipment.

My $.02, if you're not going to the Salt Flats to see how fast it can go, then it's not worth the $ and effort. Aluminum will weigh a ton, it will have to be fairly thick to hold it's shape. The bottom of the car doesn't have enough empty space for a diffuser type bottom. I think a flat bottom could be dangerous. If you don't get the center of pressure right, you'll effect (most likely adversely) the handling, maybe to the point of loosing front end traction. I think that maybe you should think about a bigger air dam in the front if your feeling the car lift at high speeds.

 

I don't see how a flat underside tray would create downforce. I thought in most cars the tray was there to reduce aerodaynamic drag in the bottom of the car.

And if you look at the bottom of the 360 Modena, there are two tunnels beside the transmission, which create vacuum as the air flows under the body thereby sucking the car down and creating downforce.

I am no expert on the subject so if I am wrong then please enlighten me.

Want cooling? I think we've finally found a good use for the front air dam ports Honda provided us with, but closed them off with cheapy covers. I quick chop with a coping saw and a couple of tubes would do wonders here...
