Just got a 2003 S281 SC, 6100 on the clock... Bone stock, Beautiful car... but what is up with the boost???
At 3000 rpms im getting like 4-5 psi
and at 5500 rpms it finally gets to 8psi??
is this correct?? i thought these were suppose to be twin screw supercharger and it seems more like a centrifugal then a positive displacement blower?
would a 66mm pulley fix this...??
