My trick is to use a screwdriver in one of the bolt holes to gently lever the opposite hole into place - then all the person on the wrench needs to do is to rotate, and that thing can get quite heavy very quickly!

Based totally on mathematics, I have two answers: a low of 270 lbs (122 Kg) and a high of 315 lbs (143 Kg). John Hervey supplied the seed figure of 1200 Newtons, and Tom Niemczewski supplied 1400 Newtons. It is possible that both figures are correct depending from where you take your measurements if the lower figure is the minimum required to start to compress a relaxed strut while the maximum is to completely compress it. I was mistaken in my previous post stating that the door struts are charged to 1400 psi. The "1400" was correct, but it was Newtons -- not psi. As for what the charge really is, I have calculated this to be from 153 to 179 bar (2225 to 2596 psi) which is a LOT of pressure. Can anyone verify this? The next thing to try is calculate the change in strut charge according to whether it is compressed or relaxed. A difference of 200 Newtons would help test my theory, but I'm bored with it already. Maybe tomorrow. So Rick, how are you doing measuring this experimentally? For those of you who enjoy math: 1200 Newtons = 1200 Kg*m/s^2 = (convert to Kg by assuming gravitational force is 9,80665 m/s^2) = (1200 Kg*m/s2) / 9,80665 m/s^2 = 122,4 Kg = 270 lbs The rest of my calculations are based on the premise that the strut is in a static mode. Therefore all internal force vectors mutually nullify each other with the exception of the force exerted perpendicular to the cross-sectional area of the rod. Assuming a rod diameter of 9,98 mm = 0,00998 m; therefore, the rod cross-sectional area = (0,00998 m/2)^2 * pi = 7,82E-5 m^2 So for the low end, 1200 Newtons applied over an area of 7,82E-5 m^2 = 1200 N / 7,82E-5 m^2 = 1200 Kg*m/s^2 / 7,82E-5 m^2 = 1,53E7 Kg/m*s^2 = 1,53E7 Pascals = 153 bar = 2225 psi (whew!) And if you understand any of this, join the geek club. Two characters come to mind: Anyone remember Poindexter in Felix The Cat from Romper Room or the yellow chick in the Fog Horn Leg Horn cartoon in the Bugs Bunny Road Runner Show?

If anyone wants you can e-mail Ron directly on this. Marty, this weeks moderator) I have seen the new Star Wars Episode II movie twice now , and that seen is not in the movie, sorry to say but it is computer generated, However relating back to the topic of Industrial Light and Magic wanting BTTF car information... who is to say it wont make a cameo in 2005's final Star Wars film, Episode 3.. just thought id comment that although a cool picture, that it is NOT in the movie...

I will be driving to Tucson from San Diego, arriving sometime on the afternoon of Thursday, 25 Jul, and departing early on Sunday morning, 28 Jul. If there are any events going on during that time, or anyone in the area would be interested in getting together, please contact me at dmcox@xxxxxxxxxxxxx Given the temperatures in Yuma this time of the year, I'll definately know how well my a/c is working by the time this trip is done!

Most likley the won't work without changing > the resistance to match. I'm allraedy further down the road: I bought a heavy (40A rated) automotive relay that has a coil resistance of 84ohm. I've allready taken out the original relay and have put in wiring to connect the new relay to. The new relay is either going to be mounted to the RPM-housing or I'm going to put it next to the relay on the sheetmetal in the car. The only thing the coil is connected with is pin 15 giving it 12V after ignition and the collector of a BC338. The BC338 pulls the coil to ground (well allmost; you lose about 1,4V because of the transistor and a diode agains reversed polarity). I will make some pictures of my modification and put them on the web in the next couple of days. Thanks, Jan van de Wouw Thinking Different... Using a Mac... Living the Dream... Driving a DeLorean... #05141 "Dagger" since Sept. 2000 -------------------------------- With the higher resistance of the coil the transistor has to carry less load (150mA opposed to 200mA), so apart from putting in (or on) the new relay nothing needs to be modified. ________________________________________________________________________ ________________________________________________________________________ Message: 7 Date: Fri, 19 Jul 2002 10:08:56 -0000 From: "janvdwouw" <jvdwouw@xxxxxxx> Subject: Re: driving with doors open? --- In dmcnews, Martin Gutkowski wrote: > My real reason for this post is to relate something that > happenned on the way home from Supercar Sunday this > last weekend.

I totally agree with Martin, the experience was great; some people asked me if I was going back to the future; well in fact I was; just one hour, but I was :-) The only downside I found on driving this way is not having a mirror, so a couple of passing motorbikes startled me and when all of a sudden we could make speed again I pulled the dor closed while in motion. BAD IDEA! Because of inertia and wind this caused my door to partially jam on the front latch pin. Not too bad fortunately, but just enough to not be able to open the door as usual. When standing still I close my door with both hands to guide it a bit more and close it properly. I obviously couldn't do that while driving, so I used one hand and couldn't guide anything. In conclusion|: driving with doors up; fine if not too fast and on level surface, but close them while standing still of you could wind up crawling out over the center console...
