Thread: Gear Drive Question

Tweet

i build and machine engines stock to race engines. them pj gear drives make good paper weights. if you know any thing about what they do and how they work you would not use one. the power stroke is not as smooth as one would think with the floating idler gears they turn the cam gear in to a ratchet and add harmonics they are not a donovan or milodon 3 gear drive they are not really the same but still strait cut steel gears will add harmonics if you can tell me how much is good for any engine? or to much you will know things bust less is better and that would be a chain or belt drive.no gear drives in any engines i build
