Happy New Year to all!

Looking for anyone with experience on Nisonger Superchargers

I realize they are out of business but anyone have anything good or bad to say about them?

Have a boat with 454mag mpi's and these are installed?

should I remove them - I really prefer stock and willing to sacrifice the extra speed

engines have 200 hours, ~ 100 of them with the chargers?

(I plan to scan for what rpm ranges the motors have seen but have not done so yet)

do they have any resale value?

thanks, Tom
