NOx becomes N2 and O2 when it reacts in a reducing atmosphere. If the fuel mix is exactly right, all 3 can happen together. The air pump is good when the engine is cold and the fuel mix is rich. One hot, the pump is usually not needed. Bleeding air into the exhaust will create an oxidizing atmosphere in there and cause NO2 emissions to be very high. Too much air will dilute the exhaust and all gases, including the CO2 will be too low. Emissions tests monitor CO2 to detect an exhaust leak.

Boyce" <[EMAIL PROTECTED]> Subject: [uuc] Re: Has BMW Design Lost Its Way? Thought I'd throw in my $0.02... BMW certainly could be designing nicer-looking cars. *However*, I've been pretty pleased with the styling on most of the '90s-era cars -- where does that leave BMW to go? At least they're trying something different, and combating the idea that "all BMWs look alike". Re. Specific models: E46: The sedan's grown on me. The coupe was drop-dead gorgeous to begin with. The M3 looks positively mean. Z8: Drool... The best-styled BMW in the past two decades, IMHO. New 7er: Um...not as ugly as I would've guessed from spy photos. I kinda like it. But I'm not sure about the Volvo-esque rear end treatment. New 5er: If it turns out like the Z9, BMW is in trouble!

More aggressive pads will be a little more expensive (1.5-2X). SS lines are nice on the track, but not a must - add about $100 or so for them. As far a labor goes, it should take about an hour to change just the pads. Make that 2 hours if you are also changing the rotors. Add another half hour if they also flush the fluid at the same time. So you could be looking at up to 3 hours labor being charged, times $80/hr labor rate, that's about $240. So your brake job could set you back anywhere between $160 and $700 depending on what exactly you want to get done and who does it. Or you could DIY in a Saturday afternoon for half the money ;) - -Luis Marques '97 328i Ryan Keefe <[EMAIL PROTECTED]> wrote: > > Four pads and four rotors are sure to need to be replaced soon. > Assuming I stick with OEM parts and a reputable independent shop can > anyone give me a price estimate including everything (parts, > labor...).

I pretty much like all the newish models - basically anything this side of 1990. I like the amenities, I like the styling, blah blah. Am I a true aficionado? I doubt it. But I'm probably right in the middle of your average BMW owner's tastes. Do I like the older BMW's- 2002's etc? Not really. They just look 'old' to me.

The rotating inertial of a disk, rolling on its edge, is 50% of its mass. If all the mass is concentrated at the outer edge, the rotating inertia is 100% of its mass. A tire and wheel is pretty close to evenly distributed. The wheel itself has more mass towards the center and will have less than 50% of its mass as rotational. The 4x rule is completely wrong for wheels and tires. The rule is closer to 1/2 x. Saving 5 lb through light weight wheels will have the effect of saving 6 or 7 lbs altogether. Saving 5 lb through a lighter tire will have the effect of saving 8 or 9 lb altogether. Lightweight tires have a greater effect than lightweight wheels, although the effect is small. Brake rotors are somewhere in the 1/4 x range. Now an engine flywheel has far more effect, especially in the lower gears. Here the effect is close to 30x in first gear and closer to 2x in 5th. Driveshafts, axles and such all have an effect but are insignificant compared to engine and flywheel inertia.

It wasn't always perceptible, and I know that other cars (esp. Japanese) puke out this smell. But i noticed it a lot more often than usual. What are possible sources for an odor such as this from the M3? Or did I just maybe (hopefully) get some funky re-formualted gas in VA, MD or NJ?
