OK then, everyone has a secret :D

other possibilities are to use a plastic diff cup, aluminum spider gears or just 2 spider gears ( which eliminates a crosspin and 2 spiders), running it without oil or with just very little oil, lighter diff outdrives, and lighter ring/pinion gears, like those from vorza  :P  You can not hide any secret from me!

Just picked up two 37t MOD 1 pinions. A three tooth change is going to mean a lot more heat. Id rather spend $26 on this then spend $1000 on twin 2028's. I want to reach 120mph with the 2200kv motors, then move on to twin 2028's and shoot for 150mph

What was the heat like when you got 108mph on one motor?
Because I am thinking of seriously overgearing my motor for the next run.

Are you still running RWD? If so how did you lock the CD

My thoughts on the 108 run was that it started out with both motors then during the pull the gear spun loose. I did run 104 with one motor tho lol

Temps weren't bad at all actually. The nice thing is the stock blur has a built in thermal cut off. I have not triggered it yet.

I am not going to get my hopes up but maybe just maybe I am able to reach 100mph with one tork motor.

But this 104 was on foams right?

Yes

I would try to do some kind of aero mods to it and cut weight where you can.

Wow, 180 kph, that is fast.

Gearing was 34 pinion, 35 spur?
What is your diff ratio?

I have found his secret, he is using the latest composite all-plastic diff, which makes it the lightest diff in the market ever made :D Behold !  Image

One motor has a brand new set after I bent one shaft on that 90+mph crash. IDK about the other lol. I think setup will be the max and heat will really start to be an issue

The truck is once again evolving lol. This time it will be made from carbon fiber to shed weight and ive replaced the entire power setup. I used a 4 ply for the core (9 plies) and two single plys for the top and bottom. Making the sheet 11 plies in total with a thickness if just over an 1/8" thick. It 12" wide and 24" long and I plan to make more plates for the nitro. Also will be making new bulk plates out of the CF too.

Image
Image
Image

Picked up two hobby wing 150a pro escs because I can no longer keep the blurs together lol

Image
Image

Still cant get over the size of the esc

Image

Decided to go with two Leopard 1600kv motors that will be run on 6s each, but I know they can be run on 8s later down the road

what has happened to the the speed controllers? they look just ready for some warranty repair...
the CF chassis is great!
But I do not understand why you decided to buy 4082 leopards instead of 4092 ones??? It is sure that even these 4082s will be more powerful than a pair of torks, but why not have all the power that is available ???
BTW, I know I have said it many times, but I wish I had your equipment :D
Good luck!

I can run these on 8s later down the road. What sold me on these was a car that weighs over 10lbs running one 1600kv on 8s with the XL2 was pullin 146mph. He also has a Steve Neu motor a 1574 or 77 i dont remember. anyways he said the leopard ran cooler and faster than the Neu. Besides these bad boys were only $62 each. Ill max these out and hopefully ill be past 130 mph then ill probably go to something around 1000kv lol idk.

Size difference between the two, the cans are the same but the 1600 is taller.

Image
Image

Started the mock up in the old chassis to check for clearance issues. Everything fits but I have decided to make things just a tiny bit larger.

Image
Image
Image
Image

This is how I think ill mount the on/off switches but knowing me ill change my mind later lol

Image

Now I tried a few different positions with the escs and Ive decided on mounting them side by side to create a slim profile and keep more inside the truck

Image
Image
Image
Image
Image
Image

This is the template im going with for the new chassis. Its got built in air straighteners and again has a little more room for the wires. The idea is to help with heat and keep things smooth and slim

Image
Image

Oh and its 7/8" longer than the old chassis to give me a little more room to proper mount my hump pack for the rx

Image

This is the setup ive decided on for mounting the escs. Cant wait to cut them out of the carbon fiber
