I know theres another thread just like this with dyno numbers but im curious on boost numbers here. Just like the other thread i think this one should be just boost numbers and nothing else... ex: Mods- GM stage 2, AEM CAI= 16psi. Just curious cause i wanna see how many psi i can run safely. So everyone..... post your ****

 

Look down @ my signature.

 

17.5 PSI

 

Up to 22 PSI in winter with the 2,6" pulley, now 19 PSI in spring season and the cat removed.

 

I got on my stock '05 last night, it was about 60 degrees, and i only hit 11+ PSI. I'm near St Louis and don't live at extreme elevation. So WTF?!

 

13.5 with the injen intake

 

13.1 stock

 

Stock you should only get 12.5

 

Some of the gauges aren't zeroed correctly, so anyone seeing over 12.5 stock is gauge error since the system bleeds off anything over 12.5psi.

At extremely high elevations a stock car may see lower boost but some cases are gauge error also.

To check your gauge just turn the key to the on position (not starting position) and the gauge should read zero.

 

15.6 with installed mods in sig. Should drop a little once the exhaust gets here.

 

12.5 - 13.0 stock with k & n typhoon.

stage 2 installing tomorrow and will post new psi.

15lbs with the mods in signature

 

I get 16.5+ psi with the mods in my sig when running the 2.9 and 14.5 psi with the 3.15.

 

17.5

 

15.5 psi

 

12.5 completely stock

 

I get almost 100 Kpa in 2nd and 3rd gear between 90 and 95 in 4th

that is more than 12.5 psi (XXXKpa x .145) = Psi

 

17 psi (120Kpa)

 

15.5psi w/ InjenCAI + GM Stage 2.

 

Same here

 

Nice to see all three of us about the same numbers!!

 

im getting 18psi with intense 2.8 and k&n cai

 

15.5 w/mods in sig.
