not sure how this will affect vibration significantly.
assumptions I'm making:
1. the manifold stiffness is >> the crane stiffness (thick tubing with large section vs. lil pipey)
2. vibration amplitude can only be decreased by:
a) reducing the excitor (engine vibration, chassis vibration)
b) isolation of the excitor from the target
c) moving the resonance frequency of the target far away from the excitor frequency(ies)
The cranes don't really do any of those. They DO provide a little bit of load bearing capability against the weight of the turbo / mani, but that's pretty much it.
If you want reduce vibes, you can really only increase stiffness (reinforcements, cranes) of the system or increase mass of the system. I'd argue that increasing stiffness will only raise the resonant frequency of the vibration to a higher rev range, and not above the working conditions.
adding mass will probalby help but might make the weight load much worse than it already is. But if you're building a crane, might as well build a bigger crane!
