ive got a sierra cosworth runnign 353bhp on rolling road its damaged at the moment due to hitting lamp post ( my dads car he hit it lol ) bt when ever we have owned a turbo car and had it tuned we have always alowed aroudn a minute of cooling down so the oil is removed out of the turbo as it is healthy for the turbo and even the head in some cases, i do it to my audi a3 2.0 tdi it has tuning mods done to it so i class it as a performance diesel now you s3 peopl mite laugh a little even though it has 100ft lb torque more than the s3's
