Great stuff! Thanks for doing the experiment. Torque limitations can be overcome by gearing, but not HP limits. I'm just as pleased that the passers by and shop staff were open-minded about the EV thing.
I wonder if a "traveling dyno" exists that could be transported to NEDRA events... - GT > -----Original Message----- > From: Mark Farver [mailto:[EMAIL PROTECTED]] > Sent: Saturday, September 28, 2002 3:09 PM > To: [EMAIL PROTECTED] > Subject: Dynamometer testing > > > I ran my Ranger on a chassis dyno, both before and after > conversion.

The gearheads at the performance shop were I made the runs were quite impressed.
