From: Windsor, On
110 PSI front rotor
109 PSI rear rotor
Are these numbers OK for a s5 turbo block?
What's spec? I have NO idea.
Also, the person on the inside of the car forgot to hold the throttle at WOT, would that throw things off?

The test will only be totally accurate if perofrmed on a warmed up engine, and with the throttle at WOT.
New spec is about 120-125.
VGC is 110-120
Good is 100-110
Getting weak is 90-100
Poor condition is under 90.

Don't forget that the compression difference between the two rotors (and also between faces??) has a spec.
Cold medicine has me all messed up and I can't rmember what the allowable difference is...
