need 87 s4 compression #'s...
 

need compression number specs for running compression check/test.. Anybody direct me to the spot for this or give me the numbers please!!

for a S4 turbo you want to be above 90 , 100 would be nice . new ideally around 115

service limit at sea level is 85 psi. variance service limit between rotors is 25 psi.

Over 100 is "good".
120 or higher is "fantastic!"
Anything under 80 I'd be prepared for a rebuild.
