It has 236k miles, but we plan to buy it and part it out, so mileage is not an issue. That means that nearly everything on it will likely be for sale, except a few things that will be kept. The body would make a perfect candidate for a track or all out race car. The bad news: It took a minor hit in the right front, which slightly buckled the fender, and broke the plastic airdam off, and the windshield is broken. No other damage to the body. It has been sitting in storage for an unknown time but has a current license tag, so it's prolly been sitting for less that a year. I have to know pretty soon, as we don't know how long the car will still be there. It can be restored to really good shape with a couple grand.

What can I do with my Volvo S80T6 unit? I know on the Bimmer I can just replace the head unit. But, some of these other marques use a big a$$ crappy head that takes up a ton of space.

I'll give you $500.00 for the car as it sits. Where is it anyway........ now to the issue at hand. That seems to be awfully low mileage for needing a transfer case. My iX, with a LOT of track time, lasted until 262k miles till we replaced the transfer case - though it was 'over' maintained. - - We've not found any acceptable way to rebuild a case. Next best is to find a crashed iX and liberate the case, though by this time it will have a lot of miles as well. - - Face it, if you want to keep the iX, spring for the case and front drive shaft. If not, my offer still stands. dan ------------------------------ Date: Fri, 14 Mar 2003 19:21:30 -0500 From: Phil Marx <[EMAIL PROTECTED]> Subject: [uuc] Re: <E28> Springs/Rubbing/Offset/Fender Rolling >"Ron J" wrote: >Thanks for the pointer on the drivers side being normal a few inches lower. >Now I wont need springs and just need to roll the fenders. I hope you didn't get that interpretation from what I wrote. I said the clearance is less on the left rear. That has nothing to do with ride height, as I thought I explained. Whatever. Do you even know what the offset of you TWS wheels is? It should be marked on them somewhere. Usually in mm. and following an "e" designation of some kind, depending on manufacturer, country of origin, etc. If you get much less than 20mm on the rear, you will have problems.

I don't think they're actually cut, but just rolled (folded really) very tightly up underneath. mine are the same way.

He said that CD's are better than records as far as signal to noise ratio are concerned but if the CD unit only samples a waveform, say eight, times a second then it will give a poor approximation of the actual sound. There are some CD players (home hi-fi stuff) that sample as much as 128 times a second and sound like you're in the music hall. That said, I agree with the comment that replacing one part of a stereo system will only point out the deficiencies in other parts. It looks like I have a choice of starting down this slippery slope, listening only to heavy metal, or just turning the radio off and listening to one of the most beautiful engines in the world (as one person noted).

(BMW content at bottom) Burt, I think something must have been lost in the translation. CDs use PCM sampling at 44.1 kHz with 16-bit quantization. This means CDs have 44100 samples per second to reconstruct the original musical signal, and each sample has 16 bits of precision. What this means is that CDs can, in theory, completely reconstruct any signal from near DC (0 Hz) to right below 22.05 kHz (half the sampling frequency) and the noise floor of the system is around -93 dB dithered, which is slightly less than a 65536 to 1 ratio between loudest and softest sounds. This spec is used by CDs everywhere, and doesn't change, modulo implementation details. The engineer was probably referring to an implementation detail of a CD player usually called the oversampling ratio. These range from 8x to 128x (or more), and depend on many other things in the system, and so can't be used as any indication of quality of a CD player. For example, CD players using multi-bit digital to analog converters typically have oversampling ratios of 4x to 16x, while delta-sigma converters must use very high oversampling ratios in the neighborhood of 128x to 256x. If you want, I can explain why oversampling is used (cost and efficiency), but this is already way OT, so I'll stop. Email me off-list if you're interested. Brett asks how a new head unit can improve a CD changer's performance. It can't, but if the head unit is a weak link, then it may be holding back the CD changer. For example, CD players can have tremendous dynamic range, and may ask an amplifier to drive a speaker to very loud levels. If the amp or head unit can't drive the speaker loudly enough, it's holding back the CD changer. There are still more esoteric reasons. OBMWC: I installed a Phatnoise Phatbox in my E46 328Ci, and it's one of the best things I've done for the car. Up to 40 GB of MP3 files, and a usable interface to navigate the hundreds of tracks. It pretends to be a CD changer, but uses the disc selection buttons for different purposes. It's driving the stock stereo which is good enough for me --- once you've heard a really good home audio system, the best cars pale in comparison, especially when you add in road noise. The Phatbox uses a removable hard drive cartridge. - --Andre ------------------------------ Date: Fri, 14 Mar 2003 22:28:40 -0500 From: "Rob Levinson" <[EMAIL PROTECTED]> Subject: RE: [uuc] Replica wheels from Discount Tires They will generally do a fine job of keeping rubber under your car and allowing forward motion. However, be advised of these things: 1) Note that there is often a weight penalty with less-expensive aftermarket wheels. 2) Check the offset carefully. 3) Note that the E39 has a different hub size that other BMW wheels, check that the replicas have the right bore. 4) Remember that your M5 has staggered-size wheels. Make sure the replicas can take your tire sizes. 5) Replica castings are generally softer than OE wheels and can damage more easily. 6) You will have to get a complete set, as no replica will match the special paint on the E39 M5 wheels, and the actual spoke pattern will be slightly different. I am not trying to scare you off of aftermarket or replica wheels - most are quite acceptable and Discount Tire is a reputable retailer. However, it's better to know what the differences from OE are ahead of time. - - Rob - ---- Original Message ---- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: RE: [uuc] Replica wheels from Discount Tires Date: Fri, 14 Mar 2003 19:19:26 -0600 >Anyone know if these wheels are okay for an M5? >The stock wheels on my 2000 are out of round and bent to heck... >Houston is repaving every major street...

I've never heard of a Lincoln with a BMW powerplant. The motor in that era of Mark VII was the 5.0 V8 from the Mustang GT if I recall correctly. There was a 4 cyl turbo motor in the T-bird in the mid-late 80's - that used the Ford 2.3 l motor that started out life in the Pinto :) Mark Kittock '96 328i Sport Pkg; 17"OZ,H&R Sport, X-brace,Turner Motorsport bars >> > Groups, > > I've heard that the crank out of a 85' Lincoln Mark > VII L6-146 2.4L DSL Turbo is the same as the one thats > in the 524td.
