as above

where would you be able to get this tested?
whats the rate of a standard engine as well?

Hmmmm, i cant remember, but i think around 120psi? Might be a bit off there but. Depends on the condition of the engine. The important thing to look out for is if the pressures arent even. If theyre all low itll be wear, but if one is low it may be a damaged valve, piston, rings, or plenty of other things. You can pick one up yourself and do it yourself, or drop down to your local mechanic. May not even charge you if you rip all the plugs out for them, and then replace them when done. Supercheap auto will sell you one of two types. Either a screw in one with metal thread the same as a spark plug, or a push in one with a taper. The tapered ones are a little bit of an annoyance to use. But make sure you get the correct thread if you use a screw in one! Most come with several adaptors

Next time im up at newie ill bring my tester ok.

If u just wanna find the pressure on each cylender then i got a gauge u can use. If you wanna find out what ratio your compression is then ive got no idea, but i believe it invloves a complex formula. I could be wrong though.

good pressure is anywhere between 100 and 600 psi i think u will norm find it to be between 100 and 200 though all the ones ive tested have been

To measure the compression ratio you need to remove the head and measure the capacity of each combustion chamber using a burette. Then measure the capacity of each cylinder using a internal micrometre. Calculate the ratio from the results.

130 is the aim

on my old rebuilt 4l motor it read 160 accross each cylinder, ran standard compression but had a reco head, wasnt even bored out or anything
