Do any of our trackers, or anyone who's replaced there driving lamps w/ brake cooling kits, want to give up a passenger side OE "clear" lamp w/ the black housing for a few American coins?

The 928 does feel like more work on the street for everyday driving, and driver vision is better with the M3 as well. I drove my '96 M3 and my '80 928s at 3 different tracks for at lease one day each. The 928 is so comfortable, it feels much flatter and stiffer in the corner. Of course I don't know how much to attribute to tires. I started with A032s on the M3, and went to R1As. On the 928, I started with street tires, and went to Hoosiers.

Suzy, I apologize >for its length. I have a pulley myself and was >hoping to get some of your feedback on it... >The Danger of Power Pulleys & >Understanding the Harmonic Damper >By Steve Dinan There's been a very interesting debate on this very subject on the UUC digest. I hope no one will be offended if I repost one of the latest articles. [begin included message:] Date: Thu, 14 Sep 2000 11:56:53 -0400 From: albert jenab <jenab@his.com> Subject: [uuc] more UD pulley stuff Neil, Thanks for your earlier response. I did a little reading and web browsing and came up with some more stuff. In CF Taylor's book on engine design, Volume II Chapter 8, there's a lot of material on torsional vibrations of crankshafts for various engine configurations. Basically what one is interested in is the critical speed, or that frequency where the significant torque components of a particular engine design excites the first torsional mode of the crankshaft. This turns out to be solely a function of crank length L, as measured from the center of the flywheel to the center of cylinder number 1 rod journal. The critical speed in cycles per second is given approx. by 460/L. I got a rough measure of L to be 28 inches, and comes out to just under 200 Hz. You go through the numbers and since the first big torque component on an inline 6 is third order, you get a rpm of about 3900 [(rpm/60)*3 = ~200.] as the engine rpm at which the critical speed is hit. BUT the center frequency of the torsional damper is almost exactly twice that (410 Hz). [note from Andy - someone discovered a frequency rating on the back of the front damper pulley] So it seems reasonable to guess that the front damper is there to damp the 6th order component at the critical speed, and not the third order one. What about the third order one? Well, either it's not significant, which I doubt, or something else is used to damp it. A damper with a resonance at 200 hz would be a lot bigger. If it were a spring-mass-damper system, it would need to be about 4 times as massive (sqrt(k/m) and all that). Hard to fit on the front of an engine, especially if you are using the damper as a crank angle sensor and acc drive pulley too. Gee, what's about 4 times as massive as the front damper and spins with the crank???? I wandered around the internet a bit and found several references to the fact that the primary use for a dual mass flywheel is, you guessed it, as a torsional damper for the crank. So, let me throw this out there: the dual mass flywheel is the torsional damper for the big third order torque component @ 3900 rpm. The front damper is for the 6th order @ 3900 rpm. So do a lightweight flywheel and you remove a very large damper from a large torque mode. Remove the front damper and you remove a much smaller damper from a higher order mode. Remove both and you snap a crank because you've got the two primary torque modes undamped. Remove either separately and you may decrease your margin of safety, but it's within limits of the crank to handle it. Which is "worse"? Who knows, but if I were worried about removing a little damper for a higher order torque component, I'd be real worried about removing a much bigger one for a lower order one. - -Al 95 M3 [end included message.] As to whether Steve Dinan or Albert is right about the dual-mass flywheel being or not being a harmonic damper, I can't say.

Zygmunt Motors (http://www.bimmerparts.com/) is having a special on foglights, and it says "COMPLETE WITH BRACKET AND BULBS" but I'm not sure that that includes the plastic clip...you'll have to call to see. You can buy only one side if you want. Price is listed at $40 each side, but there's a bimmer.org special for $36. http://www.bimmer.org/m3/messages/messages/23730.html -Chris __________________________________________________ Do You Yahoo!?

The ONLY reason that myself (and the server) go through the extra work (and it is a lot of extra work) to keep this list closed is to try to keep the S/N ratio down so those of us who love our M3s can talk about them to our heart's content without having to put up with all the off topic posts usually associated with open mailing lists. It doesn't seem to do any good to ask people to stay on topic, so what's the solution? Turn this into an unmoderated open mailing list? If you all want me to go through the extra work to keep this list closed, you are going to have to stay on topic, otherwise there is no point. Suzy
