PSI has decided to further enhance the Genesis Engine line with a much improved product line. We have proven that we can supply hi-performance engine parts that are pretty darn reliable and damn fast. But we never sit on our laurels too long . PSI has made improvements in some of our engine parts for the Millennium. We'll start at the top with our changes for the Genesis Millennium Engines and work our way to the bottom.
All base gaskets use a metal mesh sandwiched between paper backed materials.
The Genesis Polaris engines of the past always started with an existing OEM's crankcase, which were then welded on, machined, and finalized with many hours of porting. In many ways the stock OEM cases were limiting our abilities in HP and reliability. We designed and manufactured a case that gave us an incredible foundation to start on. PSI's new Sand Cast Case is much, much stronger than its flexy die cast Polaris case. PSI's 150mm center to center on the spark plugs versus Polaris's 138mm center to center offers much improved power and reliability.
