The 190e's had an AC mode (that climate controlled the interior temp based on the position of a graduated thumbwheel), and a dehumidify/defrost mode that, as far as I can tell, just bypassed the interior temp sensors and ran open loop AC on. --SC ------------------------------ Date: Fri, 22 Aug 2003 10:38:48 -0400 From: "David A.

Dan, the most sensible explanation I have heard, read, or wherever I saw it, and I can't supply you with the reference because I can't remember it, but It might have been "Motor Age" Magazine, a pretty good free trade mag..http://www.motorage.com/motorage/ and https://www.advanstar.com/subscriptions/subscribe.asp?subid=7 Torque settings vary in their accuracy due to grease, lack of grease, dirt, lack of dirt, friction of the head of the bolt against the surface, types of torque wrench, etc. The " Stretch bolts "are also called "Torque to Yield" type fasteners (TTY). Metals all have a tensile strength, which can be pretty well held constant(in a perfect world) For example, the tensile strength of a mild steel is typically 60,000 psi, stainlesses can be 105,000 psi, etc. When you exceed this for example , with a cutting tool, or a bending tool, or a twisting force, such as a wrench, the material enters, the "plastic deformation zone" (this from my cutting tool sales buddy). A press brake bends steel this way, a shear shears it. When you bend a piece of steel it doesn't immediately become weaker..it work hardens if you simply bend the angle in then leave it. I think a TTY bolt behaves the same way, after you torque it to yield, once, it is probably left plenty strong to generate the clamping load it needs to accomplish the intended use. Now, after this long winded explanation, here is the "crux of the biscuit"..if you know the tensile strength of the fastener, and the diameter, you can very accurately predict the clamp load generated when you torque it to yield. This is the reason for the angle torquing procedure..you get the fastener close to it's stretch value with the initial torque wrench setting, then by going a calculated amount beyond that value, measured in degrees, you stretch the (hopefully carefully engineered)fastener beyond its yield point, and generate a very well controlled clamping force value, which is theoretically much more accurate than a simple torque wrench setting. Once you stretch these fasteners once, they have changed metalurgicly, due to work hardening. This is why they are not supposed to be reused. All this said, they make me nervous too, but as we all know, when you are squinting your eyes, and shooting brake cleaner down the head bolt holes, and sucking the old oil out with a mighty vac, and trying to stuff a rag on a screwdriver down the bolt holes in the block to clean the holes to put the head on with some degree of cleanliness during a quick head gasket job..it is very hard to get a clean thread interface to set the torque values consistently. I hope this is as good an explanation as you have heard.. I like retorquing too, but I guess with the newer gaskets, and TTY bolts, it is a no no. Ah..progress..!

Err, Rex was talking about cars like the 911 RS America (decontented 911 designed for Club Racing, A/C optional), the Miata Clubsport (decontented Miata designed for Club Racing, A/C optional), etc. - - Mark - -- [EMAIL PROTECTED] ------------------------------ Date: Fri, 22 Aug 2003 20:32:40 +0100 From: "Andrew Thomas" <[EMAIL PROTECTED]> Subject: [uuc] Luxury racecars Rex Tener <[EMAIL PROTECTED]> writes: ">I suspect that it's no heavier than the manual system >and only marginally more expensive, so they included it. >no one is stupid enough to try to sell a car w/o A/C in >the US, no matter how hardcore the car is otherwise." "Only BMW is that stupid. I still can't believe they thought the M3 LTW would sell without A/C." You guys plainly aren't hardcore enough. I thought that car was sold as a track-day special. The North American track-day-enthusiast's market can't be so pampered that even their racecars have to have A/C! I notice that Lotus has put a deluxe Elise on the market in the UK in preparation for the sale of the same car in the US. It has air-con, stereo, electric toys, soundproofing and interior trim. It weighs 250 lb more than the base model, loses 10 bhp with the A/C going, and drops the power-to-weight ratio by nearly 20%. Expected sales volumes in the UK? Zero :).
