2002 aero

I was cleaning out my hard drive, and I found an old article by Jeff Mulchahey from the Roundel discussing the aerodynamics of the 2002. Even though the article is from 1980 it is still current, and it is a kick to read an article from "back in the day" when 2002's were still the mainstay of the BMW CCA.

You can find the pef here: http://dl.dropbox.com/u/2328398/2002/2002.aero.pdf

Interesting indeed. Here is an aero tidbit I posted a while ago:

According to EPA (1983), addition of a Kamei front air dam reduced air drag on a BMW 2002 by 5% and reduced fuel consumption by 1.7% (see page 18 of 34).

Jeff was (is?) a brilliant guy. My recollection was he was the publisher for many years of the Tii register (80's) and had one hell of a 72Tii (Ceylon Gold) with just about every "enhancement" possilbe or dreamed about. Lat e 80's he got bit by the Ferrari bug (ferrari 328 gtb) and then ugly divorce that lost him nearly everything. I still have my copy of the "Four Throttle Flyer" was published only to the known ALPINA A4 fuel injection owners in the US (there was probably more though), nine in all - Myself, Inkatouring (josh), Jeff Mulchahey, Bob Murphy, Sherman Martinez, Gary Phillips, Chester Prudhomme, Frank Shell (Bimmer Bits) and Mike Yaskin.

Super, super smart guy as you can tell by that story.

He makes a good point about increased stability in cross-winds with the aero mods. I noticed the increased stability when I added a front air dam. I used to live in Miami, and driving over the causeway was noticeably more stable with the air dam when the wind gusted!

Thanks- that's pretty cool for 1980.

Amusingly, Peter Brock (of BRE, not ATC fame)

has been saying that an air dam's about all

you can do to a street car, too... probably for about the last 40 years.

A splitter CAN create front aero loading- and on a 2002 it won't add any

measurable drag- but to get it to work at 70 mph, it has to be pretty low.

And the roof- mounted ducting (a la WRC) can also reduce rear lift-

again, though, at legal speeds, it doesn't do enough to notice.

I remember seeing Mulcahey's Ceylon Gold Tii about 10 years ago here in Atlanta. The car was then owned by a young doctor who if I recall correctly was moving to Chicago. The car was a rolling example of Alpina, had flares, Alpina wheels, an A4 system, c/r 5 speed, interior bits, etc. As I recall the Ceylon Gold paint was looking a bit tired. Mulcahey also wrote an article, published in the Roundel, which showed how at one time, you could buy a C/R transmission over the counter and use a 4 speed for your core. Don't know how much longer the program lasted after his article but I do recall the pricing was pretty dear, on the order of a couple thousand $, for what was at that time a 10 or 15 year old car in the 80's. Fun stuff if you had the money.

I recall that article as well, have it somewhere in my Tii Register Newsletters. My recollection was that the replacement 5sp CR tans was $1200 and some change with the 4speed core, still a good chunk of change but not "crazy" money. I thought I heard the same about the car, and I believe it came up for sale again - minus the A4 injection, someone out there has the car.

I remember when I bought my car in '87, Jeff was running the tii Register. He kindly sent me all the "back issues" of his newsletter - I still have them all.

I remember thinking "thank God someone cares enough to do all this". Being a tii owner when I was just a kid, pre-internet, pre faq, was a little intimidating. As in "if something goes wrong with that injection...uh oh".

Jeff at least made me think "well there are at least a few people I could call if I really needed help". Very comforting in those days.
