eagle I beams are chinese junk, no good for any high rpm. if the rod is replaced with others within 10% of weight, rebalance is not needed, I have done it, with solid engine mounts, hughes engines says so. where are scat made
If this is true then I can go down (or up) in weight a fair amount. The Scats are a possibility, less than 2% change. Using 10% I could go up as high as 665 gram weight, that seems allot!
