Not mine. 1st thru 3rd gear is very nice, responsive, and peppy. I was and still am surprised. I think when the mod'd turbo engine goes in, it might be too much for the five speed, we'll see. The only gear which lugs or is sluggish is 4th. Once on the highway, and into 5th gear, I am CRUISING at 70 MPH or more and I got a lot of throttle left. It is definitely (current 300D NA - no turbo) a highway cruiser but pretty nice in town 1st thru 3rd gear.

I was always impressed with the power and economy of the euro 300d.

I looked up PC950s Odyssey batteries and they are over $400 for 2 of them! Those batteries are physically small and light in weight for the power output claimed. Do you really believe them? What are you doing about venting? There is a chemical reaction and there is out gas while it is under charge. How are you running the battery cables? Inside or outside? Do you have any safety precautions against shorts to ground which can start a fire or cause the battery to explode? Having the battery in the interior is a worse spot than in the trunk IMO. Car manufacturers put batteries on the correct side of the firewall for a reason.

I guess the Mercedes Benz designers for the W210 goofed by putting the battery under the back seat. Not that we care about BMW's, but they have their batteries in the trunk, what were they thinking?!

I believe them (Odyssey Corporation) to the extent that a lot of other folks have done it and 100% success. I cannot assume there is a some sort of conspiracy among different car folks on different forums. It's possible I would concede. Their warranty appears rock solid. Their reputation appears rock solid. They are on par with the anti-gravity battery, except the latter is a little more costly, but lighter and smaller. Two PC950 with an internet coupon is a hair under $400 for 2 shipped. The antigravity battery of the same caliber is around $600 for 2. Does that cost more? Yup, but 7 or 11, respectively, tanks of WVO makes me even. So far, and this is a just a guess, if something "bad" happened, then 1. It would be "news" of some sorts, 2. liability and risk would probably dictate some sort of warning such as "don't put inside of car", 3. doubling the CA is probably way overkill, but I found nothing which suggests it's bad news. As for running the cable, I am doing the same exact thing I did when I had my battery in the trunk which was inside the car. I never had a problem or issue for about 2 years. Not sure about Mercedes engineers, but they seem to be obsessed with safety. I have seen a few MBs which have their batteries inside the car. I have seen BMWs that way too. The only difference is that they have just one battery with the resulting weight on one side of the car. My weight is evening distributed just foward of the rear axles. Time will tell. I know on STD, there were some forum members who were 100% adament that no one could fit a Group 49 battery inside one of the pockets in the trunk. Guess what ? It does fit and does fit in a battery box made with some extra space. Now, without sounding like a hypocrite, I said no way on a battery under the back seat ... until I started thinking about it. Guess what? It can be done. It's a mod and mod's cost $$. Is it worth it ? Who knows. That's a personal preference. However, maybe you could post a link where the bad things you comment happened with a odyssey or antigravity battery. I looked, and no dice.

My neighbor has a 1992 (I think) M3 with the battery under the backseat.

Having the battery in the interior insulates it from the heat in the engine compartment.

It is also an anal weight distribution thing

Indeed I thought the second picture was the original - the innards look similar.

Do you have any pictures of the LSD differential cage?

(I'm interested to see what those bits look like - the EPC pictures on the Russian EPC only show a standard diff)

Here you go Army ! Pre-purchase pics !

Looks like every other open diff that I have seen (being into 4 wheeling, I have seen my share). There should be no spider gears visible in an LSD. The entire gear carrier should be filled with clutch packs and and other parts that make the 2 axles want to turn together (with some slippage allowed of course). There appears to be no mechanism in there to make that happen. Just my observation though.....Rich

greazzer · #**206** 04-14-2014, 09:08 PM

Nope, the clutch packs are in there. Maybe not so hot pictures, but it's definitely the 2:65LSD.

greazzer · #**207** 04-14-2014, 09:12 PM

Here's some better pictures of the 2:65LSD:

My W210 battery is under the back seat

My W164 battery is under the passenger seat
W164 battery replacement

Both of these have vent tubes out the bottom for any outgassing to leave the passenger compartment.

Overcurrent protection on the internal battery is handled by fusing at the battery. At least for all the accessory circuits. The starter feed is still unfused but routed in as protected a manner as possible (along the center tunnel).

Overcurrent in a W123/W124 makes me cringe. No way I can get away with the stunts they pulled on those cars. Battery -> starter -> light switch -> key -> fuse would never fly in my world.

I have been at a car accident bad enough to bring out the fire department, and I can tell you the first thing they do when they get there is pop the hood and SNIP SNIP the battery cables.

I know when the Insight/Prius etc came out they had to do special training for the FFs on how to safely de-energize the 170 V dc (Insight) or 340 V dc (Prius) or 400V+ (Leaf/Tesla) dc systems on these cars in an accident. No Thanks.

Looking at the link for rebuilding (FSM), I can clearly see clutch packs, and it does look different than one without LSD. At first glance, it looked like any other diff. I just have not seen that design where the clutch pack is hidden in the case under the side gears. Searching Google photos, I found this:
http://www.benzworld.org/forums/w126-s-se-sec-sel-sd/1481254-limited-slip-differential.html
You can understand why I did not believe you had an LSD, as the housing around the spider gears looks much different. However, I now stand corrected, and have learned something
