What compression ratio would you recommend using with 93octane/98ron.

With twins. Like pure600/hydrahp800gen2

Use 10.2 or 9.5

And would i see a lot off difference with tq down low or spooltime?

lower compression allows you to run more boost but to a detriment to low rpm performance if you have access to e85 then 10.2 no brainer

Stock compression ratio with those small turbos..with large single 9.5 cr would be a great option.

I dont have access to e85. So that is why I want to lower it

I would go 9.5 since you are gonna skim the head and block that's going to increase compression.
