dealer said 8-12 psi wtf. thats a wide range and sounds wrong.

 

14.5 if I ain't mistaken.....

 

13.5 psi

 

+1 to that... I read it from the WRX brochure.

 

13.5 unless your catless.

 

That may be the brochure answer, but it actually varies widely from car to car and in different climate temps. Not a day goes by that I don't hit 14.2 PSI in my stock 02 WRX, and I've seen 14.5 and 14.7 pretty regularly if I'm driving in cool weather with the A/C off. Meanwhile, a friend of mine with a WRX a month younger than mine peaks out at 13.3.

 

+1. I should have said 13.5 psi is the target that Subaru shoots for.

 

What does it change to when you go catless? I'm seeing about 14~ psi right now regularly, and will be putting an HKS turbo-back on within a couple weeks.

 

Well im around 15psi with stock tune and a catless exhaust. When i was seeing less then that with my stock exhaust.

 

Ah, I will have to check for a boost increase when I put the exhaust on.

 

YOURE ALL WRONG!!!!!!!!


it depends what gear your in

the dealer is correct

 

The customary gear for measuring boost is 3rd gear, same gear used on the dyno.
