Is there some way to approximate this result on HP produced? I mean, you've done enough dyno runs so that if anyone could 'approximate' from experience, it would be you.... Would you say, for instance, that it would be possible for a 50 degree increase to result in a 10% loss of power? And, do you think this 'effect' would be more or less pronounced in a NA sample, or , a non intercooled Supercharged version. It would seem to me that, compared to a NA car, my SC version already raises the intake charge substantially. Add to that the effect of a 100 degree day, and it would seem that the combined effect of hi ambient temps on top of that which the blower produces would impact mine more than a NA model, in terms of percentage of potential power robbed. _____________________________ Paul Elliott '99 Alpine White M3; <15000 mi; Forged M dbl-spokes; Rotex pads; Dinan Stage II Supercharger -----Original Message----- From: Land Shark <lndshrk@xmission.com> To: Paul Elliott <pelliott@rcn.com>; E36M3 <e36m3@bmwmpower.com> Date: Sunday, June 11, 2000 8:12 PM Subject: Re: [E36M3] Calculating the negative impact of warm air temps on horsepower >At 06:12 PM 6/11/00 -0500, Paul Elliott wrote: >>Date: Sun, 11 Jun 2000 19:03:29 -0400 >>From: "Paul Elliott" <pelliott@rcn.com> >>Subject: Calculating the negative impact of warm air temps on horsepower >> >>Does anyone know the formula to calculate how air temp negatively effects >>the production of >>power? > > > > Sensitivity of an engines power to intake temp is best characterized > by experimental work on a dyno. > > Jim C. >

(meaning they were on when you did it) the teeeeny filament is not very resistant to being banged around. next time you remove it (see below) let them cool off a while before you take the thing out. since you know how to remove the thing, just replace the bulb(s) that are burned out. they cost about $4 each from my overcharging dealership parts department. you can easily see where they go from the top of the unit, once it's removed. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

What do you mean by EVOII M3? (I think I know but not sure) Does that mean it's an aluminum control arm? If so, someone posted earlier last week that they fitted aluminum control arms from an E30 into their E36. Your car was a One Lap car no? I would guess someone changed it before you.

#6. X-brace - from Robert_Manger@mastercard.com

Date: Mon, 12 Jun 2000 09:38:58 -0400 From: Robert_Manger@mastercard.com Subject: X-brace Fellow Listers, I installed my X-brace this past weekend with the guiding hand of Mr. Ron Stygar. I can not emphasize enough his ability and insight into the world we know as BMW. I have never meet someone with intense dedication to detail and wanting to help out his fellow enthusiast as Ron. I am the first to admit that I am not the best wrenchhead and at times it would be nice to have someone with experience helping me out. Thank you Ron for your help and I have noticed the difference in the car already. very solid feeling. To those that have not installed the X-brace, install it. As a worse case scenario it will only protect that 1200 dollar oil pan. Good enough reason for me. As Ron and I learned my car did not have the inserts ( build date 5/94) so we are narrowing the gap between who does and who doesn't . Installing the inserts is fairly intuitive and easy if you go about the whole install in a very methodical fashion. so go for it. For the rest of Ron's wares, let's just say that they achieved perfection for getting the results they were designed for. Be it his short shifter mech or his clutch stop (which I purchased recommend as the best and cheapest up grade you will ever find for your car). Ron has an eye for upgrading from where the factory left off and never gives up until it has been approved upon. Folks we are talking 1000th's of an inch here. Usual disclaimer blah blah, just a very satisfied customer and I learned a great deal from him. If you ever have the chance take him up on his offer of help you will not be disappointed. Rob 95M3

As it turns out the clock and all displays on the BMW work with a back light shining through the digital display. So when the light goes out the display goes black. I simply replaced the small bulb which the dealer charged $3 for and its as good as new

One morning last summer when I was enjoying a fast paced drive up a long canyon here in CO, I straddled a large rock in the middle of the road and the x-brace took the hit...hard. It wrecked the brace, but saved everything else.

#10. Front suspension for '95 and '96+ M3's - from Rex Tener
Top
Date: Mon, 12 Jun 2000 09:37:20 -0700 From: Rex Tener <rex_tener@yahoo.com> Subject: Front suspension for '95 and '96+ M3's I am trying to verify the differences between the 1995 and 1996+ M3 front suspensions. I believe the front struts are identical across all years. Is that true? I also believe that the springs (different upper spring pig tail) and the upper strut mount (offset for more caster) were different between the '95 and '96+ cars. Do I have that right? Thanks, -- Rex Tener rex_tener@yahoo.com 1995 BMW M3, SCCA SFR Solo II A-Stock #139 __________________________________________________ Do You Yahoo!? Talk to your friends online with Yahoo!

#11. Aluminum Jacks - from Seth Thomas

Date: Mon, 12 Jun 2000 13:18:13 -0400 From: "Seth Thomas" <porsche993@mindspring.com> Subject: Aluminum Jacks Okay guys I need some help here. My dad needs a new jack for around the house and then I need one for the track. So to get one that we both can use I thought about getting an aluminum one. Yes I know they are expensive but this is my dad that is getting it. I need to pay him back someway or another. I called Steve at the Ultimate Garage and he no longer sells them. So I need to find another place that sells them. Do you guys know of where I can get one? Seth Thomas www.m3power.com www.m3ltw.com
