Hi, I recently purchased a 2001 863. It smokes some at hi-idle and more at rated RPM when under load. Air filters are new. I am wondering if the turbo's boost output is low but I can't find a boost pressure specification for this engine and was wondering if someone on the forum knows what a normal boost pressure would be at hi-idle and also at the full load rated output. Thanks Ian

I don't have the spces, but i was pretty sure it was quite low. Can you check that the impellers of the turbo have no side to side movement?
Glad you started with the easy stuff, the air filter.
