What compression ratio for boost?

[Sluggie24]

I started a long term project of building a forged block for my 04 GT 2V. Going to use a Teksid block. What compression ratio would be best for a street car running 10-14psi with a Vortech and a FMIC? Looking to make good power but not have to worry.

Id aim for a bit over 10; maybe 10.5 Gonna run E85?

9:5:1- 10:5:1 on pump gas

10:5:1-12:5:1 on e-85

my motor is about 9.2 running 93 pump 14 lbs of boost.

Also OP slap some 4V cobra heads on that shortblock build.

You can make a lot of power on 2v heads especially TFS heads.

I'm running 93 pump gas. I'm thinking about going with one of the MMR forged rotating assy kits and it looks like 9.8 to 1 pistons might be about what I should use then. Thank you everyone for the input!
