The Vanagon.com  site http://www.vanagon.com/info/lists this motor at
122 ft lbs at 3200 RPM. If there is an error, I'm sorry. Is there
another source for the number you quote?

IF TRUE this new number would equate to 82 hp crank and 58 hp wheel at
3200.  My guess is that at 3800 the engine could produce 10 more
horsepower, for 127 ft lbs torque ie 92 crank hp and 89 ft lbs torque 64
hp wheel.  While is better than a I-4, but still just in the same ball
park as the other engines mentioned.

Are you using the differnt gearing? As the driving profiles you mention
ie 5200 RPM in third and etc sound like Deisel gearing with a I-4 gas
motor.  While an I-4 gas setup on a disel gearbox would produce the
accerlation, the fact remains that at standard gearing and 3800 RPM this
motor still only has 64 hp under the pedal. What Rpm are turning at 65 mph?

 Certain I-4 engines and mods made to them, can dramatically increase the
> HP/torque ratios.

David Marshall I-4 is a modified engine at the numbers he has listed.
