Here's a question for you guys with a lot of VW experience. How much difference is there in the apparent smoothness between a counterweighted and un-counterweighted crankshaft? What effect does displacement, bore and/or stroke, have?
None - presuming that both are correctly balanced. The counterweights are used for structural reasons.How much difference is there in the apparent smoothness between a counterweighted and un-counterweighted crankshaft?
not very up on VW....so as long as we are here I can learn something.....when you say counter-weight....is that a pivoting weight like on the counterweight aircraft engines or is it just a larger lobe on the bottom of the crank opposite the rod?....In either case I would assume the idea is to balance the weight of the piston and rod and do not see how cutting it off would be a good thing.could cut the weights off
Some people attach counterweights to the Ford model A crank used in the Pietenpols. In the case of N34KP the weights are attached with cap screws and welds on the ends.
