even though there's no accurate correlation.

we got a 12:1 de build here reading 180psi, it was like 130 with stock 10:1 pistons in beforehand

Then you got a bad gauge, 130 on a "flat top 10:1" DE is a bit low!! My Ve stock had 215 and with the notched N1 it now has 270psi

hmm, well i've had mixed results, suppose it depends how hot when done.

I remember one test showing 265-270 across the board. I was struggling with det on first mapping, and fitted a 1.5mm cosworth gasket which still gave over 250psi.

I could do with another comp test when at full temp to make sure i guess. But it's even across the board so it's healthy

thicker headgasket... there you go, compression reading is fair... hope you have a daughterboard setup to sort the Detonation... dont botch the high comp setup like I did
