Cr is it of course but this is a pump gas deal on V-power. Dom Thumper runs the old Isky .660 and has done for [email protected]:1, no issues on pump, I could not persuade him to do that.
Thats too bad because he gave up quite a bit believing pump gas CR doesnt matter and the chart that shows a 1-2% gain from raising the CR from say 10:1 to 11:1 which isn’t true.
