losmo Posted July 15, 2005 Share Posted July 15, 2005 Just went thru the Toyota manual for my 86 Dolphin and came up with the following for the 22RE engine with Auto trans and overdrive. 116 Horses at 4800 RPM 140 lbs torque at 2800 RPM Maximum speed in 2nd gear 68 MPH Maximum speed in 1st gear 44 MPH . I would think 4800rpm is a bit much and 2800 not enough. Obviously you would have to meet or exceed 2800 for max torque and any more would help on the horses. Without a tachometer, it seems to me that 3500 would be a good speed for the engine to run which may put you at about 50 or 55 mph. . Has anyone tried to come up with details on this while driving? Just curious. Jerry Quote Link to comment Share on other sites More sharing options...
Gulfstream Greg Posted July 16, 2005 Share Posted July 16, 2005 A guy by the name of Marco put together an excell spreed sheet that will calculate your rpm mph using tire sizes, transmission type etc.. It was dead on for me. I think 3500 to 3900 is a good power range. I (4x4) typically cruize at 65 mph at around 3200 rpm. Rigs with 14 inch rims typically cruize 60 mph at 3200 rpm. Here is the link to the calculator http://www.toyotamotorhomes.com/gear_ratios.htm Greg Quote Link to comment Share on other sites More sharing options...
