another Compression Ratio question

Even those 600hp Mercīs have stock compression, there is no need to lower compression in idi engine. Direct injection engines have much lower comp at stock.
I have now sold my 10mm pump and will get 12mm pump soon. Iīm now hunting 150 crank hp/L, 100hp/l is so easy from 1,6  :wink:

My fuel comsumption has droped big time and the main reason I think is due to the lowered compression (18.5-19:1)/increase in engine displacment.I"ve consistantly been getting around 575km/55L.Before with stock CR I could get 825/55L.


Maybe it's too early in the morning for me, but isn't that an increse in fuel consumption?
