Hello,

I just installed an F6 cooler into my XR6t and fitted a speco manual boost gauge, I took the car for a quick spin and boost seem to hit 11/12psi under full accleration (isn't the standard pressure 6psi??). would fitting an F6 cooler make the boost climb this high? or is it possible that I haven't fitted the boost gauge properly? I installed the boost gauge into the F6 cooler hole and ran the tubing through the firewall gromet.

any input welcome.

Cheers.

you need to plumb the gauge into the inlet manifold if you want to see what boost the engine is running. A car making 6 psi at the motor may actually be making more than 10 at the turbo, the motor will not see this due to pressure drop through coolers and tight pipes etc

can't you run it from the tube connected to the top of the bov?

really? that would be heaps better because at the moment I have had to temporarly mount the gauge in a different position becasue the tube wasn't long enough. Could you post a pic of where the tube can connect to the BOV.

Cheers.

Well where you have plumbed it is on the high pressure side of the inercooler. Your seeing how much boost the turbo itself is making. Not how much boost is actually getting to your inlet manifold.

yeah mate, you need to put a T-piece into the vacuum line on top of the blow off valve, the hole in the cooler is for the Typhoons boost pressure sensor - not a boost gauge
