    Default water psi on suction

    Im buying new gauges for the swtd and was wondering what range gauge should i get I've seen oil psi gauges used and the such. Autometer makes a water psi gauge that goes up to 35 is that enough?

    Not sure what kind of pressure you will see with a jet. I put one in my Eliminator after losing a raw water impeller to hydrilla sucked around the water pickup.

    Mine shows just under 5 lbs at idle, and in the 13 to 15 range at cruise rpm.

    I used an Autometer Blower gauge with good success. 0-60 psi. The one on the left.

    Personally I'd get something that allows for a higher range , we have used oil pressure guages with good sucess

    Josh used these liquid filled Marshalls recently too

    the faster you go the more suction pressure you'll run usually . if you start messing with the hardware you'll probably be tuning @ 15-65psi depending if you race or not(from what i've heard). i'm only at 45psi . but if you land the thing on a shut down you can see if the pressure spike if you have a 100psi.thats what i'm running & i got the gauges at a hydrolic store . chrome bezels, white face, liquid filled $14 each. i think most guys that blow the suction pieces apart get spikes @ 100psi.(standard berkly stuff)
