I want in, too!Dan, how necessary is a tranny cooler? Oh and don't all non-R model FD's have a tranny cooler (vs the R's that come w/ dual oil coolers)?

Personally, I'd be a lot more worried about the 1500F exhaust pipe now sandwiched between the underplate and the underside of the car, than the tranny, but that's just me!
Also, anyone trying to go to these lengths of "backyard" aero tuning are fools, IMO. For one thing, no such tuning is necessary even for typical track driving, and secondly, you would have no clue about what exact aero effect you are achieving. Lowering the car and running a front lip/rear wing are about the only reasonable aero tweaking you can accomplish without being a member of a serious racing team.

I was at JGTC too...flew clear cross country. It was AMAZING. That said, still, how did you guys get "back stage passes" so to speak? Ppl in the pits, people in the garage, people chilin w/ and interviewing Mr. Amemiya, etc...?? Hook a brother up!
I'm sorry wha?

Well the reason I brought up this small off topic question of under panles was because a guy with a stock integra GS-R did it an took a second off his Q mile. It was on TV, don't remember what the hell it was though. Thats why I decided to ask. Track testing it like that is what I was going for.

In this thread, someone mentioned the various types of wings, some optimized for short courses.
Check them out here:

There's also the new to F1 Centreline Downwash Generating (CDG) rear wing, which is basicaly two smaller wings aft the rear-wheel, but it got the "thumbs down" from the FIA tech chiefs, so it probably won't go into effect until 2008:

Man is this picture big enough and why does everyone always bring up old threads?

well im pretty sure the bernoulli principle is a fact not a theory, but youre correct in that there is more to it than purely the air foil. What youre talking about is angle of attack. You could put a angled plane in the airstream and create downforce due to the angle of attack and its equal and opposite reaction to pushing the air up. the downside to this method is the drag it creates. I think most spoilers use a combination of these effects.

Rob, the AF engineer, whom I personally know to be a good guy, and is not only knowleageable in his field of engineering, but also in the workings of a rotary engine, explained in textbook manner the most common priciple, the pro Bernoulli, or air foil theory.
I said theory, because amazingly, this is not fully proven. Recently, there is another theory of lift based primarily on Newton's third law, (for every action there is an equal and oposite reaction). You can actually see in the picture the air being deflected up away from the wing, thus pushing down on the wing, and creating downforce.
In the end, it is likely a combination of both these priciples.
Although I am not an engineer, (I'm just a general surgeon), I was also in the AF because of my love for aviation. Too bad that love did not coincide with my field of expertice which also did not coincide with military thinking. I'll be glad to discuss that in private with anyone thinkng about a military career.
Anyways, that car is totally awesome!!

Also, the F1 CDG wing concept's purpose was to decrease downforce and to decrease turbulence behind the car to facilitate passing. In current F1 if one car follows another too closely it will lose much of its front downforce.

the wing on your car is the opposit of a plane. on a plane the top of the wing is sloped to speed up the air moving accross it while the bottom craets drag with the air this differance creats lift on your car it does the oppisite the air underneath is moving faster and the top of the wing defelcts the air to creat the drag to creat down force. they work together not just one face ot the wing pushing down. that is a bad *** car though RE has a shop about 25 min away and they have a red one there that they race down in chiba the thing has 22" wheels on i am not sure if those are the same but it gives you an idea of how far those roatry gods can take a car i have 17's and they get close to the wheel wells. RE-A rocks
