What needs or can be done to a 2.0 crank to improve on it?
Knife edge? Polish it? High tech coatings? Soak it in Jack? (and don't give me any shit like "drill it full of holes to lighten it' (IMG:style_emoticons/default/wacko.gif) ) Paul |

I think if I were into this again - I would do the following:
1.) Lighten the piston as much as possible 2.) Cut the seats of the cylinders and pop the piston out so that I had about 0.030 from the top of the cyl to the first ring land. 3.) Cut the deck of the piston to compensate. 4.) Gun drill the piston pins to reduce weight 5.) Lighten the big and little end of the rod as much as I could 6.) Lighten and polish the rod beams 7.) Massage the crankshaft as mentioned 8.) Buy hi-strength fasteners for the rod caps 9.) Reduce the flywheel weight as much as possible 10.) reduce the impeller fan weight as much as possible. 11.) Port match the heads 12.) Use Manley Pro-Flo ss valves 13.) Ahhh Hell with it 14.) Build a stock motor to spec and motor happily down the road (IMG:style_emoticons/default/biggrin.gif) |
