If you reduce the rotating mass of the engine, it will actually drop more rpms than a stock motor, less mass to move, less mass to change direction, quicker reaction time. A car rotating a heavier mass would do as you say. It is the same discussion we had 4 years ago on this list. Write up's are fine and great, but going over the top is just entertainment. 30-80mph time improvements would be real information. You dont have to race or dyno it etc. But you do everyone else a favor by showing the actual value for the money or sometimes a complete waste of money. I see M3s at the track all the time and people are coming up "Hey, I added this, it sure feels great now blah blah blah, how much do you think it added" in the straightest face I can muster, I usually say between 0 to -10hp. Dynos or real world timing is the only way to document an improvement. Somethings might make the car feel better or easier to drive etc, but doesnt always = a improvement in HP. I have spent many hours on the dyno, racing, instructing, track days etc. I will just say there are lots of things out there for sale that dont work as advertised. Make a car louder, people swear it is faster. Sell something to somebody for $300, they swear it is faster, as why would 'they' have spent $300 on it. It is people like Robert and his post that help us decide what to buy. Nothing against him or the post, but I just found it funny about his 'barking'comment. Havent barked a gear since high school, as it is bad on the trans, clutch, u joints etc. But sure was fun back then. How bout just taking a extra 15mins to do before and after time tests to document the 'real' improvement. Imagine how quickly we would get thru the fluff to the real goodies if we all did that?

A car rotating >a heavier mass would do as you say. This is true of reduced mass, ie - when you move to a lighter flywheel. However, with an UDP, the reduced mass of the pulleys themselves is negligible, and the key change is the reduced parasitic drag of the accessories - mass of the drivetrain (or rather, rotational inertia) kept as a constant. A reduction in drag can only serve to bleed energy out of the system more slowly. - Chris

#4. Radio Dies - from KResener@aol.com
Top
Date: Wed, 16 Jul 2003 21:53:02 EDT From: KResener@aol.com Subject: Radio Dies Just back from a two day road trip during which either my amp or radio decided to die on me. Symptoms are the radio or cd player will play for a few minutes then sound dies and all I hear is a slight pulsing. If I turn off for a few minutes, it'll play for a few minutes, then die again. When this happens with a cd playing, I can barely hear the cd real, real low, even with the volume cranked. First couple of times it happened the sound gradually decreased in volume, and the sound became very muddled, like blown speakers or something. Now it just dies. Collective wisdom of the group? Any easy tests to determine if it's the amp or stereo? Kurt '95 ///M3

#5. suspension R&R - from Bruce

Date: Wed, 16 Jul 2003 21:17:28 -0500 From: "Bruce" <gobuffs93@attbi.com> Subject: suspension R&R I got my trackline kit from TC Kline over the past few days (not the best buying experience, but I digress). I am wondering what parts I should change while I am in there? I don't want to change these springs and shocks, get an alignment then change some other parts and have to get another alignment. Specific part numbers would be great (as would any pointers to how-tos on install- I have found the one the Bob Tunnel did on the RTABs but I like pics as well). If Bentley is the best resource I can go get one of those as well. My car is a 95 (10/94 build) and is my daily driver. I don't need track specific parts but if they don't negatively affect ride comfort and will last longer/are stronger I will go ahead with them. I am sure this has been covered as nausea before, but the archives are difficult to search thru at best. You can reply privately if you wish. Thanks, Bruce 95 M3

I haven't seen many documented (third party) dyno results from UDPs, so I thought the list would be interested. For "real world" data, I had planned to run a 1/4 mile drag on our dyno before and after the UDPs, but I ran out of time (it was too late in the evenings, and my neighbors would kill me). If the various vendors would send me their UDP sets, I would be willing to do a comparison between the different brands. I think Eurospeed High Performance did a UDP comparison, but they used an OBDII car, which confused the issue too much. I made the comment regarding "barking" 2nd gear because it surprised me. I shifted like I normally did but caught lots of rubber in 2nd. For anyone that has studied tire mechanics, look at a mu-slip curve, and you will see that it doesn't take much additional power to go from stick to spin on a tire.

I got some time to spend in the garage with the race car windows again. After a quick trip to Autobahn and another to Sansossio Autobody in Natick I had two passenger side window sets ready to go with fresh new rivets (don't ask) where I had removed one. :) I had one working and the other would just click and was playing with both with them not installed in the door to try and figure out what the difference was. I think I found out but the result is a drag. It seems that if you run the motor to it's furthest extent you can "lock up" a window motor unit and all it will do is click. So... You guessed it... I now have two complete window motor units with that only "click" when you try to run them up or down. This is the relay click you will hear if there is too much resistance for the window to go. At least I think that is what it is and is probably for safety or for motor protection. Anyone ever done this? No need to admit it publicly but I am curious as to if anyone else has ever done this (just might make me feel better) and if they figured out any way to make the unit serviceable again.
