Yes, the car body of course complicates things but the same/similar applies to the body (fuselage) of a plane, boat or whatever toward most other applications. I wouldn't call the top plane a splitter, as its not splitting air directionally which is what a true splitter does. Its merely a wing, thats all. The lower plane again produces the down force. Remember this thing has two functions and two surfaces via two planes. The upper _and_ the lower plane, which is physically affxed to the deck lid and also acts as the units base. - Janq

I agree with your assessment, Janq, and think it agrees with most of the technical analysis I've seen on the topic. I also agree of your assesment of the "base", as you probably know from my 50 or so posts on the topic
there are some dissenters with respected opinions, though, so the wind tunnel would ultimately be the judge. Have a good one. |

Attach silly string to the back of the car then drive down the road at varying speeds with the upper plane in place and a chase car following behind. Then repeat withthe upper plane removed. I'll bet money that the chase car will use its windsheild wipers much more often withthe plane removed than when its on. - Janq practiced in McGyver science |

actually, one of the best tests I've seen was amazingly similar to that

The tools are unorthodox but the science & application is real and relevant. Somebody should do it and post their detailed results. Race are you listening...? - Janq |

Janq - Read waaayyyy back in this thread. I pretty much said the same thing you did in laymans terms about disrupting airflow with the exception of the trunk portion of the wing providing downforce. I also stated in that post that someone on this site also taped small streamers all over his GC RS to show air flow and illustrated it with and without the RS wing. The smaller, than STi, RS wing did increase airflow off the rear glass. Without the wing the streamers never left the surface. Rainwater also has been known to just swirl around without running off the glass while the non winged GC is in motion. So, no wind tunnel is really needed. Just some auto paint safe tape, some streamers, an open road, someone willing to take off their wing as a comparo (or a wingless STi) and a car to ride along side with a digital camera. Feel free to play myth buster or fact maker!

Unfortunately fast forward to yesterday and it seems folks forgot it or ignored it. I agreed with you 100%. And yes the streamers (or yarn) thing will work fine too. We cycling folk use those on bikes to test for aerodynamics in tucked and normal riding position. - Janq |

The codex was actually one of the worlds first encryption devices. A tube that could only be opened by rotating its various sections to the correct code and pulling at the extremities. The tube contained a message made of papyrus wrapped around a vial filled with vinegar. If you tried to force it open the vial would break and dissolve the papyrus. But you are right, many of Leonardo's sketches included theoretical applications of the modern airfoil such as the helicopter and his famous flying machine. Sorry if this is off topic but the Italian in me felt it should be mentioned. Anyway what would really be great is an aftermarket spoiler. I've thought long and hard of trunk swapping but it leaves the back looking far too bare not sexy enough. Something that integrates with the hood would be better. If you could somehow find a way so that the bottom half of the wing does not curve up at the left and right extremities then I would be in. I've searched far and low but have found nothing. Does anyone know of an aftermarket spoiler like that? Or should I follow in the footsteps of raceengineer and be the first to walk the path everyone thinks of but no one dares? |

Michaelangleo...LMFAO!
Thanks for correcting me on that one. That must have been a Freudian mind slip or something...but its very funny, to me. Yes, I was meaning Da Vinci. As for 'Codex', I'm correct on that one. I have a modern day reproduction of one in its original Italian script with English sub-references in my library somewhere. I found it discarded on top of someone's recycle bin years ago. When I saw it I immediately recognized it and my eyes went like this Anyway, it was a master blueprint book created & printed by Da Vinci himself and details out the specifics toward many/most of his ground breaking theories and observations including amongst others the theory of airfoils & flight. Its a fascinating read. In fact as I recall there were five that he made (they all have individual sub-names) with one being lost/destroyed and the remaing four are in various locations with Bill Gates having bought one a few years back. For more information on The Codex (not the papyrus decoder) either take a visit to NYC and see it at the 'American Museum of Natural History' or learn more about it via their website; http://www.amnh.org/exhibitions/codex If you know about and like the payrus decoder, and are Italian too, then you'll absolutely love learnign about Da Vinci's 'Codex'. - Janq P.S. I'm still laughing at Michealangelo....thats what I get for free verse writing without going back to make edits. P.P.S. Hi Rob! Last edited by Janq; 09-05-2003 at 10:00 PM. |

The best thing to do is to hit the "Preview Reply" button which is to the right of the "Submit Reply" button. Doing so will bring up a detail of your post and what it will look like both in structure and in actual 'print'. Typically duing the day I skip this feature for sake of time as I just write whats on my mind and type it out then let it fly... At night when I have more time I tend to go through what was dumped from the wet cell and edit for spelling, grammar and/or the ocassional ham fisted statement which as you know I'm prone to throw out depending on my mood and the subject (i.e. EVO's are slow ). If you jam something out and need to revise it after you have hit the Submit button there is (or should be) an 'Edit' button below your post which will allow you to go back in and revise your statement. An example of which I made to my previous post in the postscript. Regards, Henry |

Ok, say if I wanted to buy a paintable set from you, how much would you charge me. I need to get this upper deck portion out of my view and off the car out of sight from cops, ricers, etc.

Thanks for the link. Back on topic though, seriously, it would be AWESOME if there were some sort of aftermarket spoiler that blends in with the trunk. Something like the spoiler you can get for the M3. Something that doesn't leave the back completely naked. Something not quite as gaudy as the wing. Don't get me wrong I like the wing and I do believe it is functional I just don't like the attention that it gets from law enforcement and the ricer crowd. |

If you are ever in NYC be sure to stop by and check out that Codex exhibit. Its fascinating stuff for a techie and/or history buff, not to mention an Italian. - Janq |
