Hello everyone,
i am new here and signed up to help me learn as i go through building my project boat. i figure this is the best place to post this question if not please show me where. 

i am going to be running blown BBC setup and am wondering how the cooling system is plumbed with a jetdrive installed.  i know the jet has a discharge port for engine water supply which i will run to a raw water screen with a pressure regulator built into it. i also read the optimum pressures are to be regulated down to a high of 20psi and low range of 16-18 to prevent blown headgaskets, is this correct?   also i would like to know how the average plumbing is done since im running a more race style motor i dont believe i will have a thermostat, bad idea or will i be ok?

i have been repairing cars and rebuilding motors or transmissions for a while now so i have a bit of technical knowledge (i am by no means the man just saying i know some stuff), if i could get a reply with technical terms that would be great the more i learn the better.

Thanks,
Alex

Search around a bit.   Several different versions of how to plumb the water lines have been posted many times.  There are a couple of good diagrams somewhere around here.   And welcome to the madness. 

ok i found the charts i and i understand them but i still have a few questions.

if i use a regulator to control block pressure do i still need a thermostat or can i ditch that?
i have the option of running 4 an fittings at the coolant passage locations for each head.  if i do this i will inject into the intercooler dual hose in the rear, come out the front dual hose to the block inlet(waterpump mount) put a cross over in the rear passage for the heads and come out the front of both heads to 2 seperate dumps in the back of the boat.  there is no water injection for the headers because it has O2 sensors for the ECU system. i will add it later and run the ecu in non-O2 sensor mode and run like a banderlog injetion unit.  this way i can run it in places that require water injection.
Is the Banderlog a good product to run or am i over complicating the water injection system with it? (just looking for opinions on this banderlog product, no sale pitching)
