Elliot Harper probably ran a 4.5t in his ”ghost” Durango prototype....lol..... There are many YouTube videos where guys use 3.5t motors boosted + 2S to reach 85mph to 110mph.... Eventhough these guys were doing speed runs, I think 75mph with a 3.5t boosted is a piece of cake......
My tc4 3.5t is already faster than that Awesomatix in the video... Imagine if I add boost...
My tc4 is also geared at 8.409FDR, and can be geared even higher, since it does not even warmup good after six minutes running....
