Prowler gets a new dyno today!

[jason at scirocco.org (Jason)]

Hey Patrick,
         Congrats on breaking the 100hp mark!

         Tell your dyno operator to start lower than the 2900rpm or so he 
seems insistent on starting the run at!  He's missing your torque peak each 
run and apparently either doesn't realize -- or doesn't care.   True, what 
happens below 3000rpm isn't relevant to a dump-clutch launch and redline 
shifts, but it certainly would be nice to know your peak torque, no?

         Have him start the test at 1000rpm, not 3000.

My $0.02
Jason
