    • Cubes - Prefix 9.0 liter X-Treme Viper V10 stroker motor puts down 747 naturally aspirated horses to the wheels

      You might be asking, who is Prefix? Wasn't someone called Arrow Racing marketing a 9.0 liter Gen V Viper stroker motor? Well, Prefix is the parent company and they purchased Arrow a few years back. It seems they have decided to market the motors under the Prefix brand now.


      The Prefix X-Treme engine takes the 9.0 liter motor and adds an aggressive camshaft as well as ported heads and a new tune. It doesn't come cheap:


      Getting this kind of naturally aspirated is never cheap. Nth Moto was able to match this output on the stock motor with a cam on E85 however.

      No denying the extra cubes provide more torque though:


      It would be interesting to see this motor tuned on E85.

      Either way, this is roughly 900 naturally aspirated horses on pump gas. No replacement for displacement...
