Re: Bottom crank jack shaft.
o really, 4 dragsters can't move a semi? if that was anywhere near true, it would be because top fuelers have only one gear, they slip the clutch for half the run and because they are geared for a top speed of over 300 mph. if the gear ratios were right, you could easily power a semi with a dragster engine if dragsters had multi speed transmissions. hp is torque times rpm, so you can substitute one for the other as long as the hp is the same and you compensate with the gearing. i don't know why you can't accept this concept.
some people say that a motorbike defeats the purpose of a bike. i tell them to get a flintstone's car.
