The good news is that everything held together! The bad news is (and only if you call it bad news) I didn't hit 80. It did 76.7 I think that is all the stock truck will do with the cheap 3s Zippy Rhino 4900mah 20c batteries. I used 26t pinion and a 53t spur. I have on order a 25t mod1 pinion and a 34t mod 1 spur. Plug those numbers into the calc for the fun of it. Here is a pic of the ride height.

The zippy's cant be that bad if they just set the speed record for an E-Revo. lol
At the end of the day that thread is good publicity and will get people excited about this stuff. The last thing they want to see is a post about how he is going to blow his MMM due to ripple currents. Sometimes doing great things on a budget is more satisfying than dumping hundreds of dollars on some quality batteries that we know will break the record.

Ok, so this genius is going to go from sucessfully running gearing that specs out at 78mph with no tire ballooning, to gearing that specs out at 117mph... Wow, this guy is a sharp one... Going up a few teeth at a time is the way to do it. I doubt his new gearing will do as well as the old setup, as it will most likely stress the batts to the point they will puff, or worse.
I would like to see him run those packs till they hit the lvc and see what kind of mah he can put back in them, if they even hold up. I have a feeling that he may get half of their rated capacity back in, if that. A few runs is all they will give him, which is fine as speed trials are not ususally done repeatedly without a charge and cool down period.
So what has he proved? Newer lipo formulation resists puffing better than the old stuff. Sure he got his revo to go fast, and if that is his thing so be it. That setup will not have good temps and the lipo will not give many cycles at that load. So he is effectively ruining a good lipo, and putting the rest of the system at risk in the process. All so that a bunch of whining kids can "congratulate" him on having the fastest erevo. Kinda like being the worlds tallest midget IMO.
Now if he had used better packs he would have hit over 80mph, and not overtaxed his packs. So his battery investment would actually be an investment.
Bottom line is that we do not see Nic Case overgearing his setups and using cheaper batts to achieve his goals... Going fast costs money, and wears components out quickly. Not trying to rain on anyones parade here, just want to shhow things for what they are. Every noob that sees what he is doing will think that he has a solid setup, and waste their money on it too.
