Raised CR from 9.4 to 10.6

What does 1.0 bump in compression net in HP & TQ? Is there a general rule of thump. Also I was talking to a guy that said it will impact the TQ numbers more then HP, is this right?

Horsepower is a function of torque, if you increase horsepower you are increasing torque and visa versa. What most people mean is that increasing peak torque or peak hp.

Either way, i don't think there is a hard and fast rule, but with compression comes high octane gas, which is an opportunity to bump timing.

so if you took 2 motors the same except the CR 1) 9.4 & 2) 10.6 the only benefit would be more timing? Just trying to learn here lol

rule of thumb is 2-3% hp for every 1 point change in compression ratio
