This year however, I would like to do a few of each. I have followed most of the post on the subject here over the last year, and I feel I am now well prepared and aware of most issues involved (driving theory, tech issues, safety issues) but I still have a couple of questions: 1) are there any places in northern/central NJ where I can try on and purchase a helmet ? I understand it is possible to buy them on line, and also I am pretty sure I know what to look for, however, I would like to try a helmet for fit before buying it, I would also like to see a number of different models and brands, and compare their weight and features. As a first time buyer I would feel much more comfortable doing this in person rather than on line. 2) there aren't that many NJC schools per year, and the ones at Lime Rock are impossible to get into (I got rejected already twice) What other options do I have to attend schools in the north east ? I am aware of Lime Rock, Summit Point, Poconos and Watkins Glenn as being fairly close, are there any other tracks within reasonable driving distance, and what are some of the major groups/clubs that run schools there, that I might have a chance to get accepted into ? 3) same question for autocross, I am aware of the NJC events - what are some of the other clubs that run autocrosses I could attend in the area ? 4) finally, I would like to install a camcoder in the car to record my laps. I understand there is an easy way to do this in a car with rear headrests, however, my M3 doesn't have those. I have also seen people mouting the camera on the harness bar (I think) which I also don't have, and don't plan on getting any time soon (I have made a decision not to run a harness without a roll bar) What other options for mounting the camera in the car are there ? Any info would be greatly appreciated, Thanks, - -Adam Fila BMW CCA NJC '95 M3 ------------------------------ Date: Sat, 19 Feb 2000 16:30:00 -0500 From: Peter H Reinhart <[EMAIL PROTECTED]> Subject: [uuc] Re: [E36M3] In-car video Very cool videos John!

Taking on the task for the first time late at night when You are tired is not a good idea. I realized that I had the cam lobe facing up on the number one cylinder when I undid the bolt so the eccentric swung back towards the cam (towards the center if I am wrong in my assumptions). I tightened down the bolt and just went to bed. Now I know the errors in my way and need to fix it. My question, if I use my nifty remote start switch to turn the cam lobe down (the way it should be), can I then loosen the 10mm nut and turn the eccentric by hand until I can see the hole?? Is there going to be any damage associated with my incompetence?? Is there another way to fix this before I turn the engine over without doing any damage?? Should I just scrap the job and leave it for the big boys??

Turn-in technique is determined by first becomming familiar with the inherent handling characteristics of your car, you know, the ones you've became acquainted with on the daily commute, the snow-covered parking lot, the unexpected drivers school, or auto-x miscues, etc. Once you are actually AWARE of how YOUR car functions, the ultimate turn-in technique is then realized by simply "looking ahead" to where you want to be. The turn-in will then be executed automatically, at the optimum point, without ever giving it a second thought.

Vaughn" <[EMAIL PROTECTED]> Subject: [uuc] <E34> Possible Head Gasket leak All, I have noticed, on my '92 535i (78k), what I call 'a lot of exhaust vapor' coming from the tail pipe in the mornings. To me it appears 'excessive' but without you seeing it, it becomes a subjective observation on my part. It still appears to me to be more than what I see on my wife's '95 740i, my sons '90 325i & my '96 Z71 4x4. My first thoughts are that I have a leaky head gasket. The problem is that I don't lose any water in the cooling system, which I would expect if the head gasket was leaking. The "steam" does go away after about 10-15 minutes of 'neighborhood' driving. However, I still have a lot of vapor after the 5 min. (3 miles) drive to work in the morning. When I pull into the parking lot and let it idle for 10-15 sec., I see "a lot of steam or vapor". I tried smelling the exhaust & even tasting the vapor on my hand, to see if it has the 'sweet taste', as mentioned by others on the digest, as being the sign of antifreeze going through the exhaust. I can't determine if it has the taste or smell of antifreeze. But keep in mind, I don't make it a habit to taste this stuff, so I don't know if I know what I'm looking for. The car seem to run find, with the exception of what I am going to call 'hesitation' on mild to hard acceleration. Doesn't feel like a miss, but more like a 'stepped' acceleration, which I think may be a fuel problems. I solicit all the suggestion and advice that you guys can give to this older novice shade tree mechanic. Let me add a post script here. I just replaced the plugs this morning, inspecting the old one from each cylinder. All of them look pretty good, but I did notice what appears to be rust at the end of the thread on the one from the last cylinder, next to the firewall. Could I have a 'seepage' problem when the engine is cold, and as the engine heats up & expands, seals the leak? If this thought is correct, could re-torque possible correct this? And how would I go about that? TIA, Richard V.

Ya know what happens when you go all the way to 1st when ya THINK you grabbed 3rd in that 5 to 3 shift? <chuckling> You hear this screech followed by a pop and then silence, as you look back in the mirror and see a oil flowing freely from yer car as you coast to a stop on the side of turn 1. And later, when all the gang is in the pits lookin' at your car they'll say kewl thinks like 'Wow, I've never actually SEEN a rod come through a block before"..... I never.....ever.....grab more than one gear at a time when going full bore. 5 - 4 - 3 - 2- is the sequence when coming into a corner at speed for me. You start skipping gears on the gate and you'll catch the wrong one sooner or later, KA-POWWWWWWW! Practice....practice....practice. This is one of those procedures that is hard to write out in print, but comes very quickly and naturally at the track when you do your driver's schools. You can sometimes overthink a technique. - - Duane Collie The Seven Sled ------------------------------ Date: Sat, 19 Feb 2000 17:34:53 -0500 From: Patrick Finn <[EMAIL PROTECTED]> Subject: Re: [uuc] Turn-in technique Ron Katona wrote: > If you're > getting maximum traction from a tire in a given direction, it can't > provide traction in another direction simultaneously.

Ron is right, there are two important factors here. The adhesion limits of the tires (friction ellipse mentioned above) limit the amount of turning that the tires can accomplish while torque is being applied (braking of accelerating). In addition, the dynamics of the car play a major role in determining the cornering characteristics...you can't think of the system as being static. Many of the complex dynamic phenomenon can be analyzed in a simple way using the following equation: Steering angle( of front tires)=L/R+(Wf/Cf-Wr/Cr)*V^2*C Where L=wheelbase R=radius of turn Wf=Weight on front tires Cf=Front tire cornering stiffness Wr=Weight on rear tires Cr=Rear tire cornering stiffness V=Forward Speed C=Constant (I think it is gravity/L but I don't remember..I'll look it up if someone wants it) The quantity in parenthesis on the right hand side of the equation is known as the understeer coefficient. In a neutral steer car, this is zero..In other words, for a neutral steering car, you need the same steering angle to achieve a turn of radius R, REGARDLESS OF SPEED. If the understeer coefficient is positive, you will need more steering angle to achieve a turn of radius R as the speed increases (notice the dependence on V^2). If the coefficient is negative, an oversteer condition exists and less steering input is needed for a turn of radius R as speed increases. (Note the consequence of this...if you have too much oversteer bias, at some speed the car will be unstable...you will achieve a turn of radius R w/ ZERO steering input!!). Remember that although this is a simple equation, it contains many dynamic factors. The Wf and Wr can change as you brake or accelerate, as can the cornering stiffness coefficient of the tires (This stiffness is a measure of side-force v.s. turning angle). And again, don't forget that if you are braking hard, the amount of turn angle you can achieve is limited by the friction ellipse governing the tires. I apologize for the rambling nature of this email, but I hope it helps.

Is it worth attending a driver's school in an >automatic equipped car? I can't imagine that it would really matter...the >whole idea is to learn how to drive YOUR car fast and safe. Right? Do it. Of course it's fine to run an automatic at the track. It may not be quite as much 'fun' as a manual trans, but with some of the cars (like my E38 740i) the computer 'holds' the gear at a high rpm when it figures out you're on the boogie. Works for me. I'll be taking The Seven Sled out to the track every so often though I think I'll sign up for "D" Group (Novice) just so I can get: a) An extremely high pucker factor outta whatever Instructor rides along as we hurl the 4,400 lb. Sled into Turn 1 at Summit. I'll be listening for little groans, whimpers and muted "ma-ma's" in the headset communicators..... b) Watch the rookie ///M3 pilots expression in the rear view mirror as they see it fill completely up with half an acre of Alpine Silver sheet metal and then say to themselves, "HEY ! That's not an ///M car....and its an automatic luxo-rod!" as they gimme that pass wave..... If you ever go out to Summit and watch the old-time BSR instructors do hot laps in the clapped out 1980 vintage Caprice Classics (worth all of $ 400, if that) you'll be stunned and amazed at how they can make that automatic chebbie on worn out tires do tricks around the course.

In the "Going Faster" book, they mention this, and also mention its a damn lot harder doing ALL gears and keeping the car stable than just one. Differing opinions. I'm still so new though, I'm just gonna do what the instructor says for now. =) - -- '95 540 6 speed, BL/SS BMWCCA Peachtree Chapter ------------------------------ Date: Sat, 19 Feb 2000 17:09:23 -0800 From: "Rob Hatrak" <[EMAIL PROTECTED]> Subject: [uuc] WTB: M3 coupe side skirts I want to convert my M3 Lux. side skirts with the motorsport skirts.
