I've been extremely pleased with the reliability of my turbo and WI with one exception . . . the WI pressure switch. I've been using Hobbs switches from Snow. I'm only getting ~6 months/5000 miles of life out of them before they rupture and start leaking.

Anybody have a recommendation?

 

Where is it mounted? Some pressure switches don't like to 'see' vacuum. So if it's pre throttle body it prevents vacuum signal stressing diaphram.

megasquirt general purpose output?

 

The pressure switch I'm talking about is one for monitoring water pressure. It's located on my water line between the checkvalve and nozzle. I'm using the MS to activate WI, but use a pressure switch as a safety for enabling EBC. I.e., no water pressure (WI failed) and I failover to wastegate boost only. Also use it to detect nozzle clogging. Works good, but seems to be a maintenance item.

 

ive been running a aem pressure monitor, for about a year with no problems

 

This seems legit? Good price too.
