I see that the 206 makes 8.8 horsepower so how much does a pro gas animal makes and could you swap certain parts from a w/f to a pro gas motor.

Asked by: rocket man
The Animal is approximately 6.5hp. We recommend to only use parts designated for each engine and not interchange them.

what is the starting procedure for an animal on methanol?

Asked by: RAMracing
The Animal engine was factory built to run standard 87 octane pump gas not methanol. This is the same standard for all of our racing engines.

Is this engine ready for a rolling chassi ? Or are other products needed to run?

Asked by: big day
There will be your standard list of parts needed to take any engine to the point of being ready to run. You will need an exhaust, pulse fitting and line to run fuel to the engine, air filter, and throttle cable system. These items as well as an engine work needed will be defined by the sanctioning body rule set you plan to run under.
