| Pre-facelift R53 Boost Pressure Is there anyone on here with a pre-facelift R53 with the original supercharger fitted and a boost gauge?
If so what pulley do you have and what pressure are you seeing?
I've got an Alta 17% fitted and at WOT i'm only seeing 14-15psi, now i'm sure it should be higher leading me to think a 15% may have been fitted by mistake.
If you've got a newer teflon coated supercharger can you let me know the pressure you're seeing as well. |
