You guys think about all the angles! Since a fluid does not compress, why not build a drag car with the engine set to run at max torque (after warm up) and put the power through to the drive wheels hydrostatically, using a higher volume pump than the motor, and use a positive control valve controlling bypass, linkaged to the pedal on the right, you could theoretically turn the rear tires 300 + mph as soon as you got the go light! can you imagine the flying parts? Seriously though, I wondered about the logic of gear ratios as a youngster when I discovered that sprocket ratio on a bicycle was affected by the throw length (stroke) on the pedal cranks. Am I getting it?
