Electric Losi 8 buggy weight?

[Mod Man]

I am in the process of a Losi 8 buggy E conversion and I wanted to know what the norm would be for the weight of this setup?

I put everything in the chassis and weighed it and it looks like 120 ounces is the all up weight (including my Eagle Tree). The setup is;

Neu 1515
12S Flight Power 2170 cells
Castle Creations HV 110 ESC
Nomadio reciever (React transmitter)
VHV-BEC
Hand machined motor mount
MIG welded piano wire roll cage under the body (this would add a few more ounces if I go with it).

Does that weight sound correct? If so, this this should absolutely rip the tires off! This same power system is running in my top speed TC4 (110+ mph car) and draws 3500 watts. In this application, I would think 2500 watts is what I will be seeing reliably.

Any thoughts?
