Carpenter has been working on the 2400 cc horizontal 3cyl. Can't see that being what they are using for Pro Stock.
Looks more like a Buell sponsored by Triumph.
Viper is going to give it a whirl next year with their proprietary V Twin.
They actually purchased PMFR to assure they will have access to the finest chassis and components.
We'll see if they can get through the NHRA mess.
