Im going to be running 17.5 blinky(no boost/no timing). After building the kit and looking at the gearing chart(in the book), it was clear this car was intended for modified motors. And after reading the gear chart its clear I cant and want be using the 87t spur that came in the kit with a 175.5 motor.
I searched online, read the charts and did the math. I cant believe the 17.5(w/timing) needs a gearing so high. So now Im debating if I should get a 72, 75, or 77 spur.
That would allow me to gear the motor for 3.5-4.0
