For reference only.  As of January 2012, the H1V8 engine is no longer offered. It is replaced by the  new H1 MAXI V8 engine!

But this is where it all started!  The H1V8 is the 1st of (3) V8 designs.  It had a difficult birth but out of the box it set records and later improved versions are still running and winning.  The first H1V8 engine was installed in my Super 7 in 2004 and 15 years later I am still driving it, running errands and an occasional sporting event.  The new H1 MAXI V8 goes back to the roots of H1 and adds size, durability and performance.
