Cooling a low boost psi

$

Hi guys please dont think i havent put alot of research time into this its just very hard to find any info about intercooling at a low boost.

im about to install a low psi supercharger. It will be 6 psi max. I realise i dont HAVE to intercool at this level of boost but ive decided i want to to increase releability and gain a little power.

I was intending to go down the air to air route for all the reasons most people do but i am now thinking about a reasonably priced chargecooler / intercooler set up. The reason for that thinking is i have such a low boost to start with reducing it further ( probably up to 2psi ) installing all the piping and cooler will have a dramatic effect and almost make not worth while.

What do you guys think ? As i understand it a watercool setup has minimal boost losses.

I know they are generally more expensive than air to air and i certainly get the impression its far more complicated science than air to air systems to get right. But does it become more complicated as the boost gets bigger and the charge gets hotter?

For example i understand i need a pump but if the water flows to fast it can be counter productive. Many of you guys dont really rate the bosch pump but im guessing its because many of you are running much higher boosts than 6psi.. will the bosch be suitable for me? Can anyone suggst a suitably flow rated pump?

Am i correct in thinking ( as opposed to an air to air system) its best for me to get the biggest sized charge cooler and (front mounted) intercooler as possible ( obvious budget restraints) what kind of sizes do you think i need to make a benneficial difference with 6psi?

Is it worth my while fitting a tank to hold extra water with a 6psi boost. I think the system would run cooler but is it worthwhile difference for me? Someone might say its essential , i just dont know.

All im really trying to do is install the same quality system / components that you guys find effective for the larger intercooling systems but scaled down to a suitable level for my boost level

Your thoughts and experiences are very much appreciated
