I am new here. I bought my first Alfa, used Giulia QV. I did compression test yesterday and the pressure is only about 8.0-8.2 bar per cylinder. Is it normal? My previous cars had about 12 or 13 per cylinder.
boosted engines, supercharged or turbo'ed, usually have significantly less static compression than naturally aspirated engines. In the old days, before computers and injection systems, it was hard to run any higher than about 10:1 unless on race gas.
thank you for your response and sorry for my late response. We did the test with and without throttle. The results were the same. I have been driving the car the past three days and everything looks normal. I bought the car after hydrolock.
