I'm going from a stock compression 2.0L to a 2.3L .30 over 9:1. I'm curious how I can expect my peak timing to change.
I've searched around a bit, but haven't been able to find consistent info.
For example, if I was running 35psi (50/50 e85/91) from an hx40 on my 7.8:1 2.0 with 17* peak timing, what peak can I expect to run at 20psi on my 2.3L 9:1?
I know there are many variables here, but I'm just looking for general guidelines for how increasing compression ratio impacts peak timing. Thanks in advance.
