During the movie The Ultimate Race, you get to see each of the team's AcceleChargers up close. Shortly after, they are captured and put together in Gelorum's car. Before capture, the Teku/Metal Maniacs have 3, the Silencerz have 4 and the Racing Drones have 4. When they are all together, however, they make 14.

Also, the Silencerz win the Cosmic Realm at the same time as Major Wheeler, with the Silencerz AcceleChargers, is attempting to take Dr. Tezla's. So how did Gelorum get it - she's seen using it later during the Ultimate Race.

As a side note, I've tried to figure put who won which AcceleCharger. Here's my list:

Fog - Drones (prior to Ignition)
Warped - Drones (prior to Ignition)
Monument - Drones (prior to Ignition)
Storm - Drones
Swamp - Teku
Cavern - Metal Maniacs
Lava - Drones
Water - Drones
Metro - Silencerz
Cliffside - ?
Ice - Silencerz
Neon Pipeline - Silencerz
Junk - Teku
Ruins - ?
Cosmic - Silencerz

Hmmmm...
