Typically when an engine has wear the compression goes up, not down. as carbon in the cylinder chamber populates space otherwise free. So, I am not too sure how the CR would go down.
There is some crossover confusion here. The static (or calculated) compression ratio (8.3:1) can be increased by carbon buildup over time, while the dynamic compression can suffer from wear (e.g. - rings) simultaneously. :D
Heh yep I posted that 3 or so posts up to clarify

LoL.. I learn something new everyday..


Thanks guys .. you rock...


well .. I have the timing set at 5 degrees BTDC for the rev limiter..

then the SPARK cut kicks in.. and has pretty orange flames shooting out with boost building in NEUTRAL and loud bangs...

sounds like a rally cars bang bang system.. LoL..

I'm backing off a little bit.. don't want to hurt the turbo.. but hell.. it's cool!
