Re: water pressure

In my mind, 25 psig is the limit at WOT. I have a Mercury Racing pressure relief valve on my engine and the most I see is 22 psig. It is the spikes that you have to be concerned with. The PRV that I use pretty much addresses that issue.

Re: water pressure

I'm surprised you get that much w/o a t-stat installed. You might find the pressure a bit lower if you tapped into the block itself, eliminating the resistance from the 2 crossover to block holes.

Re: water pressure

Take a pressure reading form the engine block to get an accurate reading.
