how many psi is a stock suby suppose to have? another question, my BOV is like really messed up, and at 4-5.5rpm it makes a WHEEEEEE noise, i got a greddy type-s, and on my boost gauge, it like shakes like wobbles back and forth but not a lot... can anyone please help?!

 

vacuum line disconected?

 

15.2 is what i saw 1.1 1.2bar

 

Im pretty sure stock boost is around 14.5-15 psi. My car peaks around 1 hkpa and I think 1 hkpa =14.5 psi. I have a Blitz turbo gauge and I think they are the only people on this planet that use hkpa (who knows why?). I dont know much about bov's but I have read that they need to be cleaned or they could cause problems.

 

yeah... no wonder im losing so much hp damn this is like horrible, a integ smoke the S**T out of me and right after an 80's hatch boned out... so you guys think its the BOV... im only like pushing 8-10 psi

 

I'm only getting .9 bar in mine now. I used to get 1.3, and the way my AccessECu is flashed, that's what I'm supposed to be getting >:-|

Stock is either 13.5 or 14.5. My mind is dead right now cause of homework.

 

Im pretty sure that stock is at 14.5.

 

Try running a search

 

Stock is supposed to be 13.5 psi (page 11 in the 2003 Subaru Impreza brochure).

 

try putting the stock bov back on

 

stock is 13.5 and should be around .09 mPa on the stock gauge.

 

My car is boosting 10 in first and 12 in the rest.

 

13.5

 

13.5 good luck
