You can add a few more lbs of boost safely at the same time have a cooler inlet temp than inner cooled only.
But to see real power you will need to add a few lbs of boost as well as a new fuel curve.

Adding boost is definately in my plans. I need to decide between spinning the hell out of the weiand 256 or upgrading to a TBS 871.
I only freshwater boat...would it be at all practical to seastrain and then filter lake water for injection?

Our base 565s with Blower shop inner coolers and high helix 14-71s are safe up to 8lbs of boost on good quality 93 octane fuel.
Depending on boost levels through out our 120hrs of testing we added several hundred hp by injecting Methanol.
At the boost levels you see on the Video per our prop math 1.24 ratio 36P 17s and slip we are well into the 1300s at the same time keeping killer fuel /air and EGT's all on pump gas and minimal lead..
You don't have to have the wick turned this far on a supercharged engine to see hp gains .
100hp can be had by accident in more moderate boost ranges as our inlet temps go down so drastically.

You need a small tank depending on your needs usually 5 to 15 gallons. At that point depending on boost level CI etc you set your system to pump either all in at a certain level or in our case red lights come on at 8lbs that means were pumping per boost signal .Or you may set to progressively come in from 50% at 4 lbs and 100% @ 8lbs again depending on your set up .Your pump is injecting pressures between 100 and 225 PSI.With that being said it takes us 10 minutes per weekend to top off our tank. The guys that actually run a water mix and not pure meth generally run distiled water as you stand less of a chance in clogging your nozzles.

I built a blown corvette and used a meth and water injection system and it worked great with NO detonation. Installed with a pressure switch that only sprayed when building so much boost.
