MrhorsepowerLSX is right about reliability and water being an issue. If you could protect it well I would say the cheapest route could be found here

I guess it depends on your budget, if your going to cover it in water often, what its primary use is.

 

With a roots style blower I find this to be false. I think a roots style blower would be what he needs. If mud gets in the supercharger than without the supercharger it will find itself inside of the intake manifold, which I find highly un likely.

 

Don't forget that you need to protect the airfilter, and what happens when the airfilter gets wet. Just saying........

Even if he runs a PD/Centri blower, as soon as that belt gets wet/muddy it is going to start slipping anyways, unless it is cog driven. But with that said,

I have seen a few setups where bed mounted tool boxes were converted into housing a turbo charger which was totally sealed and water tight, I have also seen same theory applied for air intake filters, kinda like a giant snorkel box. But if he plans to install as stock setup, money is just being flushed down the toilet

 

Would hope on a true mud truck it has some kind of snorkel setup anyway.... The occasional mudhole/trailriding truck can typically get away without one keeping in mind that the engine compartent at steady speeds through high water will actually stay somewhat dry, its when you stop you get screwed....

 

i seen some crazy procharged trucks with huge power driving through ponds with zero issues

 

As I stated, it is on how well the air Inlet is protected/designed.
