I am looking for a good 2.0L stock crank (71mm).
It is for my race engine, so I would rather have forged than billet (like the SCAT product). Who has used a AA forged crank? Any issues? Do we know if these are brand new or reconditioned to be "new"? Anything to worry about or better options? https://aapistons.com/products/counterweigh...qxoCrTYQAvD_BwE |

They are OK but softer than a german crank.
Two schools of thought with racing, a non-counterweight crank spins up faster vs a counter weighted crank is smoother, longer bearing life, especially with a lightened flywheel. What I would do is stick with a german crank, might get the german crank counter weighted. A german crank is stronger, less flex and harder journals than an AA (any china) crank. Then do a full engine balance to +/- 1g, whole assembly fan, crank, fly and PP plus rods end to end. I don't know what's available for a stock crank but H beam rods are almost 200g lighter than the heavy 2.0 rods. |
