I'm thinking about adding a rear wing for hill climbs as down force on high speed corners is a good thing.

So what are you running and where did you get it?

I like what the guys who run POC on willow are doing with wings. Making sure they get them high enough to grab fairly clean airflow. Mounting as far back as possible,

Sure you do.

At SCCA AX on a 914 the wing's highest point (including end plates) has to be no more than 12 inches above the mounting surface and (in plan view) not extend passed the plan form of the car.
The red car looks iffy & the black car is a "no way".

Good luck.

At what speeds do you start to seee downforce Paul?

I'd love to have a SCCA legal wing for autox, but also need something for hill climbs. In hillclimbs need downforce for those intermediate corners with speeds above 60, but below 100.

I saw a Noble last night which had an upward wing mounted on the rear trunk with a big wide elevated wing from fender to fender. The gap between the two looked like about a foot. It sure looked like it would provide ample down force.. for a Noble.

I don't think I have seen Randals car at a single SCCA AX event ever in past 10 years. If he's focused on Hillclimbs, PCA ax, non SCCA events who cares? In hillclimbing he is in open class. Why compromise with silly SCCA Solo AX rule that will never matter?

I can assure you know one at UFO or AAS event would ever care about whether XP car had a wing that was a little taller than SCCA rules they'd actually applaud it. There is a bit of antiSCCA sentiment in both clubs.

Hard for me to say at what speed the wing starts to work for me. I'm not looking at a speedo on an a/x even if I had a speedo. (IMG:style_emoticons/default/biggrin.gif)

I do know that I have been in a thrid gear long sweeper and the backend sticks where as before the wing in wouldn't.

There is a big difference between a high speed wing and a slow speed downforce wing. The fat leading edge of a slow speed wing makes it work.

I'll try to dig up some websites that talk about it.

I use a G-Stream wing from Paul Brown (Tiger Racing). It has 600 lbs of down force at 120 MPH.

That is a good looking wing (and car). (IMG:style_emoticons/default/biggrin.gif)

Would love to see how it is attached in the trunk.

I'll have to call G-Stream and ask what kind of down force their wing would produce between 60-100mph, where I need it in hill climbs.

Got a picture of that splitter off the car? I'm interested in how far back the aluminum goes. Thanks.

Ever think about doing a hill climb? Hoopa is coming up.

I've talked to Paul about this/this wing. If I ever go aero I'm using this exact wing because it's effective down as slow as 40 mph. This should do the trick for you. The problem with MOST wings is IF they work at all it's at very high (100+) speeds. The only down side is Paul is proud of the wing ($$$$)! (IMG:style_emoticons/default/biggrin.gif)

The beauty of this wing is you can mount the uprights where you want them.
The ends need to be in free air to generate good downforce. I run 6 degrees angle of attack. Some run 12+,degrees.Attached Image

I believe that's John Defords car. I might be able to get details if you'd like. He's kinda local to me.
