I am going to boost my d16y7 and i ran a compression test today. The numbers were (120)(118)(120)(120) The engine was warm when i did it and i did not have it at WOT? It seems like these numbers are low but they are consistent across all cylinders. Do i have anything to worry about?

 

Anyone?

 

throttle needs to be 100%open. do it again and see what the numbers are at. right now they are way to low because your throttle was closed.

 

Alright i used a brand new gauge and opened the throttle and i got 180 in every cylinder.

Those numbers are kinda hard to believe. My engine has 160k on it?

I got the same numbers on a 125,000 stock block y8 boosted for about 2years at 10psi
