UP..on the pinion, or you can go smaller on the Spur.
Just divide the pinion and the spur, then multiply that # by the gear ratio of your car/truck. So..you go..
88 divided by 24 = 3.66, now you go ( HPI Cyclone gear ratio) 2.43 x 3.66 = 8.91, and that's your final ratio..lower the number the faster..Hope this helps.

Don't forget that going up in pinion, while making the car faster down long straights, will decrease acceleration, and may actually make your lap times slower. It can also cause the motor to heat up more, which may make your car slower. Depending on what ESC you are running, going down in pinion and adding motor timing may be the way to go.
