Although the top one is replaced with a weight. Can somebody that has taken apart a 60/70 pack chime in with the weight and material Tesla used for this ballast?
AFAIK same exact size and number of modules, it's just a few of the module rows don't have batteries in them. I'm pulling this from memory of when NHSTA took apart a 60kw pack after crashing it.

This is not quite right. The 85kWh pack has 16 modules. 60kWh has 14 modules (it is missing the two modules in the front stacked section) AND each module has less cells.

The two front modules are omitted, yes. The exterior hump is still there though, with "blank" modules.
I could be wrong (second hand info) but I don't believe it's a weight, just a spacer of some kind for the front two modules.
The 60 and 70 packs definitely have only 14 modules. The 70 pack is, as I had predicted a while back, just using the same modules as the 85 pack vs the oddball modules the 60 used that had 10 cells per cell group missing.
I know this is off topic but assuming that that the 70 and 85 packs use the same cells:
* 70 kWh/14 modules=5kWh/module / 5kWh*16 modules=80kWh in the 85kWh pack
or
* 85 kWh/16 modules=5.3125kWh/module / 5.3125kWh*14 modules=74.375kWh in the 70kWh pack
So which way is most accurate?
Let's not derail this thread on this one too much, but I started a whole other thread on the topic not long ago that got out of hand with people posting craziness that I no longer look at.
In short, the 5 kWh per module number is more accurate. My actual testing puts it somewhere around 5.05kWh/module for the "85" pack modules, confirmed by a couple of others to be the same as the 70 modules (except with only 14 of them vs 16).

So bottom line ... after 85 pages 
70 kWh pack is actually 70.7
85 kWh pack is actually 80.8
70 kWh pack is actually 70.7
85 kWh pack is actually 80.8
So bottom line ... after 85 pages
70 kWh pack is actually 70.7
85 kWh pack is actually 80.8
I thought it was clear after just a bit over 80 pages.

BTR, you are amazing. Keeping a thread going this long, and being able to keep everyone's emotions in check (with some moderation here and there) is proof that Internet forums can work. Never thought I'd see the day! Props sir. Big ones.

Isn't the pano roof a good chunk of that weight difference? I always assumed my car was the slowest Tesla makes because of that.

Yeah, a few times I wanted to blow up, but then I asked myself why take it so seriously?
Im having too much fun to even care!

So are we!
It has been mentioned before, but am pretty sure some of the Jalopnik readers would enjoy this. Heck, they might drive out there to see your project and do a feature. I believe that once past the knee-jerk reaction, most gear heads will understand that this is an enthusiast car (as in this is high-tech, fast, and not a golf cart), and you can actually wrench on it a bit. Or a LOT in some cases.

Btr: to avoid financial ruin you need to do 2 things immediately.
(1) Immediately abandon this project and put the car out for recycling.
(2) Sum up whatever you originally thought this project would cost, multiply it by 5, and send me a check, draining your funds for such endeavors. This said from personal experiences with similar projects. :wink:
