My Adly 2T with BBK is tuned to launch at 4,500 rpm..it hits 30 in about 75 feet..then jumps to 8,000 rpm and it goes from 30-56mph..while maintaining 8,000 rpm.. at top speed where I cruise..50mph..rpms drop down to 7,500. By staying in the powerband..I can pass when needed or regain speed after a hill or a slow down for a curve.. I run a KOSO performance variator..6 gram KOSO sliders..a 2k clutch spring and 1.5k contra spring..
