compression ratio?

[turbocaprice]

Currently have Mahle -16 cc dish pistons wth the 65cc heads comp will b 9.5, is tht too high at 15lbs of boost? Or should I go wth the srp extreme -28cc dish to make it 8.8 cr wth 65cc or 9.3 wth 58cc. -31cc 8.5cr. Wth 65cc an 9.0 wth 58cc.

9.5 is fine its all in the tune

^ Agree. 9.5 with 15#'s will be safe (assuming everything else is setup correct and you have a safe tune).

I am running 15#'s of boost with 8.8:1 CR , which is really overkill safe, as it could take 20+#'s of boost.

You'll be fine.
