  We thank Alro Racing Systems for allowing us access to the dyno results for the Zenoah G230RC large scale car engine.
The engine was tested on no less than eleven different pipes on the dyno and used the same fuel. Also worth noting is that none of the pipes tested were optimised for this engine.
