I think you're measuring in KPH, because 100mph is FAST. If it was that easy, that you could get a 1/8th car and easily make it do 120mph, and Steve Pond wouldn't be spending thousands of dollars on that Super Nitro highly modded NovaRossi .21 to get it to pass 100mph. No video needed, because you can always speed it up and make it look fast. The GT might get a max of 70 if you still want some acceleration with a .21, and the 1/8 will most likely get to 80 but definately not 100. 120kph is about 80mph, and that sounds about right. You were most likely in KPH.
Most high-performance .21 race engines do rev higher than small block engines. But even their 40k rpm isn't enough to push a car to 100mph without major mods.
100mph just isn't going to happen unless you really dish out big bucks... sorry. [
