10 psi would bring you up to ~ 17:1 compression. A stretch for stock parts IMO if you want it to live. I saw 8 psi take out stock pistons with a good tune the first day it went down the track. Stock ring lands have limits...
On the other hand I ran mid 10s for 2 years at 13 psi on forged 9.5:1 pistons with ZERO problems, even won a 100 mile open road race.

Stock bottom end with a d1 &4 " pulley. I hit 10 lbs on the dyno. Haven't got to the track yet so I haven't hot max again since. It all depends on how you drive it. I baby it so I live at 4-5 lbs
routinely and then shut it down. I'm already going fast enough at that point.

At 10.5:1 NA I can only mange 18 degrees peak timing on 91 octane with my z06. Tuned many other cars around the same compression and can't get much timing in them either without 100oct.
I'm just posting this as info as octane is usually the main limiting factor assuming you have a good tune.
