Got the Piranha 25K spec motor for Expo class installed with a 8t pinion and 34t crown. Gear ratio's now 4.25:1 which definitely spins the big slicks for more acceleration.

Just a bit more tire trueing and then it's off to the Winter Nationals Holeshot Proxy in November.
Anyone got a mailing address to nhdungeonracer in New Hampshire? I'll pm him too.
