Best/Safest boost for my CR
I was wondering what would be the safest and best amount of boost for my compression ratio?

With that high of cr, you wont be able to run a lot of boost on pump due to kr, but on c16 youll be able to run a good amount! Just keep an eye on afr's, timing, and knock, and youll be good!

18psi max on pump and 28psi+ on c16 (atleast that was the most I could run on 91octane)

my 8.5:1 setup with the 5 laye.r @18psi w/meth was all 93 pump would do for me. got me 428 though so thats nothing to sneeze at.
