[QUOTE="G3T_TERMINATED, post: 16377775, member: 148857"] I've got Manley pistons with a 10:1 compression ratio. I tested my cold compression today, the lowest cylinder was 148 psi and the highest was 161 psi. These are within the 10% threshold. Low cylinders were 5 & 7 @ 148 psi. I need to do a warm check to be sure. But what is an average psi for 10:1 CR? I'm getting the car ready for more boost and want to make sure she's healthy. Cylinder : PSI 4: 152. 8: 152 3: 157. 7: 148 2: 160. 6: 161 1: 152. 5: 148 Any input is appreciated. [/QUOTE]
