[MNsupercharged]

How much is stock sc putting out? Stage 2??? w/3.0 pully??? w/2.8???

[thedubsack85]

stock sc i believe puts put 12.5. my stage 2 puts out 15 at peak. and i believe with a 2.8 your looking at 17+. depending on atomesphereic pressure (altitude)

stock=12.5 psi (can hit @13psi with an intake and a little more in real cold weather)
stg II = 14-15 psi
3" pulley 15.5 psi
2.5 pulley 18-20+ psi depending on exhaust and intake mods

I've hit 19 psi when it was warm out, with my 2.6 pulley. 21 spike when it's below freezing. God only knows how much PSI when my cat went a couple days ago, even if for a second. I shudder to think...

ive seen the 2.8 go as high as 19psi. but its all on back pressure man. if you were to get a header, DP and cat back exhaust your boost gauge wont read as high for some reason.
