Packer Posted July 13, 2006 Share Posted July 13, 2006 With all the info floating around this forum, someone can, off the top of their head, tell me the best RPM or 'sweet spot'to run a 237.I've got an 18 speed Quad and so have lots of gears to play with but no idea of what might be the best crusin' RPM for best economy.Fuel has gotten a little cheaper but still not where a guy would like to see it!!!Packer Quote Keep a clutchin' Link to comment https://www.bigmacktrucks.com/topic/1306-torque-curve-mpg-curve/ Share on other sites More sharing options...
