Well, a TC3 is a very good chassis for high speeds or any other 4wd shaft driven touring car. The market is full of them.
Also, there was a person who used a Hacker master controller with a 1920/5 motor and 12 nimh cells and he was able to easily hit 86mph.
With 4s lipos and let's say a 1930/5, you can reach the 90s in an instant.
The name is Alawi. You can call me Al.
Nice to meet you!
