Message-ID: <[EMAIL PROTECTED]> I thought I understood the principles of air conditioning well enough to not be surprised by most things that occur but I was sure surprised one day when I had my gages hooked up. I unplugged the auxiliary fan just to see what happens. Reading was about 230 high side but when I unplugged the fan the pressure immediately started climbing and in about 10 seconds hit 400 then the compressor kicked off. My high side cutout out is 400 but some r143a systems are higher but that is beside the point. I had thought that the effect wouldn't be so immediate and the rise would be more gradual. I would have kept the condenser cleaner on some past cars if I had known how precisely the performance is affected by the amount of air making its way across the coils. About the same time as I had this experience I ran across a guy who used a technique to charge the system by measuring the temperatures at the inlet and outlet tubes of the condenser. This technique could compensate for the effect of a condenser that is not removing heat as well due to age, dirt, clogged fins. By optimizing the charge amount this way he claimed that often old systems could keep on doing a satisfactory job (not as good as new of course) saving the expense of tearing into the difficult job on some cars of replacing the condenser. Not much application for this information for most of us. But air flow across the condenser (the thing in front of the radiator) is everything. -Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Gary Derian Sent: Wednesday, June 23, 2004 8:25 AM To: [EMAIL PROTECTED] Subject: Re: [UUC] OT: Any a/c guys out there???

Message-ID: <[EMAIL PROTECTED]> I have observed the reverse. When the auxiliary fan resistor blows on an E30, the A/C won't work at idle (due to high limit switch) and when he car is moving through the air, the pressure drops enough for really cold air to flow from the vents.

Message-ID: <[EMAIL PROTECTED]> I would like to rent, borrow, or otherwise secure the use of the factory E30 rear wheel bearing removal/installation tool set THIS WEEK. Don't need the hub-pulling slide hammer, hubs are off. Probably don't need the tool that re-installs the half-shafts in the hubs, I've done it before without the tool, and without damaging anything. I just need the use of the tool that removes and installs the bearing from/to the control arm. If you help me out, I'll make it worth your while. (Gads, what am I saying? I know I'm going to regret this.) I'm in the S.F. Bay Area. I'll pick up and deliver if local, or I'll pay the shipping if you're not local. I'm in this situation because a local CCA member offered me the "special tool", but it has turned out to be just half of the special tool, and I can't do the job without the other half. If I don't finish this bearing replacement by this coming weekend, I'm in deep doodoo. Please let me know if you can help me. Yes, I know Brett rents the tools. But they are out and not due back until next week. I can't wait (please see earlier deep doodoo reference).

By Nick Schulz Posted Wednesday, June 23, 2004, at 3:00 PM PT Michael Schumacher is the most dominant athlete in the world. The six-time Formula 1 champion has won all but one of the circuit's first nine races this year. He's also the world's highest-salaried athlete and the towering icon of the sport that claims to have the largest worldwide television audience. But his excellence goes beyond his on-track success and off-track popularity. Schumacher is nothing like Jackie Stewart, Mario Andretti, and the other motorsport legends he's now surpassed. Schumacher may be a remarkable driver, but, more important, he's a venture capitalist in a flame-retardant red jumpsuit. The 35-year-old German is remarkable because he's managed to mold an entire sport in his image two separate times. Formula 1 once had the reputation as the sport of international playboys, its well-heeled drivers drinking champagne, puffing cigarettes, and chasing women in exotic destinations like Monte Carlo. Schumacher, though, is a caricature of the Teutonic robot�a legendary workout freak who became quicker, stronger, and fitter than the competition by outworking them in the weight room. While other F1 drivers were straining in the gym to catch up to Schumacher's physical standards, he changed the sport again. Schumacher's peers don't consider him the best driver in the sport�that honor goes to Giancarlo Fisichella. But what his fellow drivers don't understand is that virtuosity behind the wheel isn't the most important skill in Formula 1 these days. Schumacher has transformed F1 from a sport to a technology war. In doing so, he's attracted billions of dollars to feed his business, develop technologies to his specifications�and annihilate the competition. Michael and his brother Ralf, who also races on the circuit, grew up as gearheads. Schumacher learned about the technology of racing while working alongside his father, a small-town repairman for kiddie race cars called karts. When he joined the Ferrari team in 1996, Schumacher was ready to get his hands dirty. The Italian automaker spent $450 million crafting its race cars in 2003, mostly thanks to sponsorships from megacorporations like Marlboro and Vodaphone. But while Ferrari has always had a stake in F1, it wasn't very successful throughout the 1980s, a huge source of consternation for such a prestigious brand. When Schumacher signed on, he was able to ensure�partly because of Ferrari's name brand and partly because of its desperation�that he would have both the resources and the operational control he felt he needed to dominate. If Ferrari were a football team, Schumacher would be the quarterback, the GM, and the coach. Though he didn't give his team the idea to greatly outspend its top rivals�around $100 million more than Williams and $150 million more than McLaren�he did teach them how to spend it wisely. Schumacher understood the crucial importance of building the team and technologies around him�if the best pit crew, technicians, and engineers in the world tailored his car to his strengths as a driver, then he couldn't lose. In F1, the drivers may be stars, but the cars are king. Every team spends the offseason in wind tunnels and with feedback testing equipment, secretly crafting improved design elements. This season, Ferrari extended its technical lead by unveiling its "narrow waist" design, in which the back of the car is almost impossibly thin and low to the ground, diminishing the drag exerted on the car and giving the car greater stability in turns. Ferrari's design excellence allows Schumacher to methodically destroy his rivals. While simple maintenance and production costs eat huge chunks out of smaller teams' budgets�a season's worth of tires and gearboxes alone can cost well into the millions�Ferrari can perpetually fine-tune a suite of technologies so that its cars perform under the most extreme conditions of acceleration, braking, and turning. As a consequence, Schumacher's car almost never has significant technical problems, a huge advantage in a sport where the ultra-expensive cars often just stop working because of technical malfunctions. To keep up with Ferrari's superior machines, other drivers have to take risks. As such, they consistently make mistakes out of impatience, imprudence, or desperation�hitting walls or other cars or just spinning out uncontrollably. In this past weekend's U.S. Grand Prix at Indianapolis, only half the cars that started were able to finish. So obvious is the role money plays in Schumacher's success that F1's governing body is taking steps to minimize the importance of cash. Formula 1 will soon ban certain electronic driving aids and will further regulate tire and engine use and testing, all in the hopes of keeping down costs so lower-class teams can compete. Schumacher is a peculiar global sports icon. He can claim to be the greatest race car driver in history, and judging from the sea of Ferrari-red bedecked fans, his team is far and away the most popular on the circuit. But he's a distant champion, respected but not adored. When Schumacher turned in a subpar qualifying performance at the Grand Prix of Canada, the fans�including the Ferrari faithful�erupted in cheers and applause as driver after driver bested his lap time. Mostly, fans are desperate for someone, anyone, to give Schumacher a fight. While few events compare with an F1 race in terms of loud, macho, colorful spectacle, Schumacher has killed the suspense. There's a sense that something is badly wrong with Formula 1, but no fans or drivers really fault Schumacher or Ferrari. They just worked hard, played by the rules, and outsmarted the competition. Two weekends ago at the Canadian Grand Prix, Renault's Jarno Trulli broke down on the very first lap because of suspension problems. Later that day, I saw Trulli at the Montreal airport, waiting in line with us race fans for a commercial flight to Newark. I asked if it was tough seeing Schumacher dominate a race that he had barely started. He just shook his head, demoralized. "Schumacher," he muttered.

Several vendors sell these sets, I usually recommend Eurosport High Performance - the folks that handle all the JimC stuff. When I bought mine, the kit came with high-temp wiring that you could splice into the headlight assemblies in case you wanted to run 100W bulbs (standard are 55W) and the uprated fuses needed. It's been a few years since I upgraded mine, but cost is probably ~$350-$400. Well worth it, as these light - even at 55W - are MUCH better than the stock N.A. light. I installed them on my previous '96 328is as well as the current '98 M3.

I am referring to the setting on the speed dial in the 6-12 o'clock range, before you get to the 1-2-3-4 speed positions. If I am not mistaken, this setting is supposed to provide a variable, low speed adjustment below the "1" speed setting. The failure mode appears to be that, when the variable speed setting goes bad, the control defaults to the "1" speed level. I say this because I had another '95 M3 for many years, and the HVAC blower control failed in exactly same way... at first the variable speed control worked fine, then failed and the variable speed control went away in favor of speed "1," all the way from 6 o'clock up to the "1" position. Has anyone else had this problem and found a solution? Bad R-pack, perhaps, or is there some kind of rheostat built into the control?
