Yea...a proper BL system will rocket a Jato to 100mph easy if you can keep it on the ground. This is because the Jato's layout allows you to mount just about any motor you want. Get a super low KV Lehner 1950 and run 12S lipo with the Castle Creations Pheonix HV125 ESC and run the stock mechanical brake (since the ESC doesn't have brakes) and you got yourself one FAST Jato.

As for the Resonator Pipes. One doesn't just increase acceleration and the other top end, they both just boost power in different ranges. This power boost translates into different running characteristics. The Dual Chamber increase mid to high power, while the Single Chamber increases low end grunt.

His Jato is most likely faster than a stock one, but I dont think you can accurately guess its speed. You need a radar gun.

Speaking of a radar gun, you can get a Bushnell one for less than 100 bucks off ebay.
