M45 Supercharger from Moss?

[FELIX_5]

Thinking about getting the JR M45 supercharher kit from Moss, it comes with the powercard which from my little knowledge isn't the best set up in the world, but as far as a plug and play set up, is it ok? What sort of power could I expect on my mk1 1.8? Is circa 180bhp reasonable to expect?

And second hand what would be the going rate for one of these kits?

Any thoughts/advice much appreciated.....

Cheers
