Hey Folks,

Are we happy with the vibration levels of the .91 SZ engines? What are the factory fast guys doing now? I've heard rumors of some running the C-Spec crank with some other mods... anyone care to share? I've also seen pictures of SZ cranks with weight added with tungsten plugs.

I my trying to avoid making trail and error changes. As we all know the process of removing the engine, un-mounting the fan and dissembling the motor is not simple and I'd like to avoid doing it multiple times.

The reason I'm asking is fairly obvious. I went and burned a few tanks yesterday in my Tempest and just am not very happy with all the carbon dust and black gruel this engine makes. Are we just running 'em?
