i am going to be purchasing one of these valves from grainger...the adjustable one (0-20psi) that flows 54cfm...
now i own the f-max kit and as you may know it has 2 threaded bungs right near the TB for the additional injectors...
i already upgraded fuel/engine mgmt..so i will not be needing the extra injectors...

now here are my 2 choices....

1. put 1 pressure relief valve on and cap off the other theaded bung...

OR

2. put 1 pressure relief valve on each of the bungs for a total of 2...
my only concern is that by adding the second one...it will double the amount of pressure it will take to open them....

ex. i want to run 18psi....so i will set the pressure valve to 19psi...if i overboost anything over 18psi will be bled out...but if i have 2 won't it take 38psi to open them (19+19)...or it doesn't work that way???

please help i am confused...

thanks...

There is a relief valve available from Greddy. Just go to Greddy's website, click "Turbo" --> "Turbo Accessories" --> "Relief Valve".

The relief valve goes onto the intake manifold. So if you set your RV at 19psi, then it'll open at 19psi or more.

The RV measures pressure, not flow. So having 2 RV's @ 19psi will relieve pressure @19psi+. Of course, have 2 RV's mean you can relieve more pressurized air (volume) than just one.

HKS sells a "pop off valve" to prevent overboost too

you say it goes on the intake manifold...will mine work being that it is 4in before the TB???
