Higher compression = higher power output, yes? My model is a 1990
Audi Turbo, South African model of the US 200. Since this damn country
can get so backwards and since the Turbo was an import into this
country how can I go about checking the compression ratio on this
thing? I think the best would just be to check the compression
pressures on it (ie, remove plug and put in gauge in the normal fashion
of compression checking) and compare it to a 200 with the MC engine
with higher compression that you speak of.

Does anyone have the measured compression pressures for the MC engine
of the 200 with the higher compression ratios? I'd just like to
check if this thing I have is the older MC of the 5000tq or the
one put into the first 200s.

Thanks.
