Accoding to saito the 150 will swing a 16x8 @9000 rpms? If this is right that should be stronger than a ys 1.10 right? That is about what I was getting out of my 16x6. The 120 15x8 at 9000 and the 125 says it will do a 16x6 @ 9000. That sounds like what the ys 1.10 will do. Are those specs bloated?
