Boost vs compression ratio

WebApr 15, 2013 · Higher comp improves off boost driving and spool time but those motors really dont have issues on low comp and spooling turbos. I dont see a need to go higher than 10.5:1 for boost. 9-10:1 is fine with ls motors. So many guys running truck take outs at well over 600 whp at 9.5-10.0:1 comp just fine. WebECR = effective compression ratio. So our above example gives an ECR of 12.0:1. This makes perfect sense, because 12:1 is considered to be the max safe limit with aluminum heads on pump gas, and 15psi is about as much boost as you can safely run before you at least start losing a significant amount of timing to knock.
