anyone no where to find the rough how to guide for working out compreesion ratios? cant remeber where i saw it. did a test today and got 8.5bar across all four? is this average for c20let's? not really sure what book compression should be tbh

8.5bar is not a compression ratio.
Do you want to know what normal cylinder compression is?
Or how to work out a compression ratio?

wont to no where the site is to work the compression ratio out and what standed compression is on a c20let.( not ratio but figures on the tester)

You could have at least worded it better 
You start off about CR, then mention a compression reading, which has nothing do with cr.
Anyway, to work out cr, you need the engine swept volume, and the head volume, and cc

He wants the compression test reading of a 20let tho, not the compression ratio.
See, it confused you too,Lol.

what i was trying to say was if you did a test on each cylinder on a brand spanking standed c20let calibra the day it rolled off the production line what pressure would each cylinder see in theory anyway
