Hmm - sparkling water in the cooling system - would that back-drive the water pump and increase more horsepower? :P I tried making coffee with sparkling water once.

I don't think you want to do *that.* Perrier is *mineral* water. It most likely has more mineral content that your local tap water. And yeah, I know you were kidding...

I have some 15" aftermarket wheels on my e32 that he likes and will buy off me, but I'll need replacements and will go to 16's. I'm hoping someone here has a set of 4 OEM or aftermarket wheels taking up precious space in their garage that they need get rid of. We're not looking for pristine, nor are we interested in bent/rashed wheels. Plus, I'm not interested in the OEM 20 spoke nor the satellite dish e32's - sorry. Please contact me off list to save everyone else the bw.

I'll bet any amount of money that the delay in the rain has more to do with the temperature of the rotor and the pad than water accumulated on the surface. It shouldn't take any time at all to clear the thin sheen of water on the rotor (how much water realistically can accumulate on a vertical surface travelling at thousands of revolutions per second?), but the constant wet airflow would most likely keep the pad outside of operating temperature. That first few seconds of braking are more than sufficient to bring the temperature up to optimal range. That would also corraborate what was mentioned above with the behaviopr being different for different pads (each with their own temperature range and friction level). -peter*g ------------------------------ Date: Fri, 12 Mar 2004 11:55:29 -0800 From: "J.

Damn, how fast are you going? A Bridgestone S-03 in 245/40-17 turns around 840 times per mile, according to the spec sheets. If you're going 60 mph, the wheel will turn 840 rpm, or 14 revs per second. The smallest tire I could find in 5 minutes of poking around the spec sheets on Tirerack's web site turned under 1200 rpm at 60 mph. That's 20 revs per second. Getting to "thousands of revolutions per second" is going to be a little tough. Heck, your engine at redline is turning what, around 7000 rpm? That's 117 revs per second - you're going to have to have some pretty tall gears to get up to thousands of revolutions per second. My Dremel Moto-Tool, set on its highest speed is doing 35,000 rpm - divided by 60, that's still only 583 revs per second...

That wasn't water, it was mud. ;-) Then holes would work real well. -peter*g ------------------------------ Date: Fri, 12 Mar 2004 09:40:51 -0800 (PST) From: Brad Couvillon <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: distilled water or not?

I think the same people who are outraged by $2.00/gal gasoline don't even blink at paying that for water. I could see maybe if it were BMW brand water...
