That’s what, 20x less compression than what it probably should have? Is this even possible? I think you need to take another crack at this compression test business. ---

> [@f\*\*\*\*r-bluntman](#): > > ok thanks to corpse we managed to get a reading of 10 - 11 psi, so now is that a normal reading and will it handle boost??? Dude a normal compression test numbers for a ka would be around 150-170 psi. how the fuck do you get 10 psi? Elaborate please. ---

The car would not run on 10psi, something would be ultra-mega fucked up. Are you sure the gauge isnt measuring in Bar? ---

> [@corpse](#): > > he means kpa, we got 160-170 psi KPa?? That would be even worse, 10 KPa is just over 1 psi. Bar would make the most sense. ---
