Blake Machine Company
Specializing in Datsun Z Car Performance

 

  • There are two ways to verify the success of a port work:
    1. Dyno run after rebuilding the engine
    2. Flow testing 

    Obviously method 2 is the wisest choice as it provides instant feedback
    as the work is done rather than being disappointed after an engine is
    rebuilt.

    Porting "by looks" is like Russian Roulette as air flow can only be 
    measured by a flow bench no matter how pretty the work looks.

  • Blake Machine Company uses a SuperFlow Bench to verify all port work
