The power peak before and after recall is 7,850 RPMS, however no two motors are the same!  The HP numbers before and after recall are around 130HP, and again no two motors are the same.  Some may have more horsepower, some less - some may have a higher power peak, some lowwer.  The recall did nothing for performance.

We have not dyno'ed a 2001 with the update pistons and mpem update.  However We have dyno'ed both 2001 and 2002 and they peaked at 7800, the 2002 has more over rev than the 2001 but both peaked the same.

We did about 50 recalls on the 01 800 and saw no gains in performance, other than most of them had the rings worn out and they definitely were helped by new pistons and rings but as far as any gains they are about the same as they were when they were new in o1.  --  Bill
