4V CNC chambers now available for CHI heads.

14/04/2006

Owners of raised dome, high compression pistons to suit 4V closed chamber heads, can now order CHI heads with a 4V CNC chamber. Our 4V CNC chambers are 74cc in volume and retain our relocated spark plug location.

These can also be ordered as an option by people that require increased chamber volumes for blown or stroker applications. And at just $100 USD - $150AUD, the need to replace those high compression pistons is now a thing of the past.
