General Compression on a Punto GT
Hi mate, and WELCOME TO THE FORUM!
Should be around 170psi in each pot iirc.
Hope that helps,
Alan

Depends on which versions u have, as there are 3 different compression ratios. 150psi to 180psi.

As above, the GT1/2 should be running about 150psi and the GT3 should be closer to the 180psi mark (think that was the right way around

should the later punto gt not be less compression running more boost hence more power just a thought i will check now
anyway less than 110 psi wont run well as a guide if your looking at running faults or misfires

Its the early gt's that run less compression, and the later ones run higher.
oh yea so it is weird maybe it's better ignition in that case capable of lighting much more compressed mix's

If you're looking to diagnose a running problem, then what littlepip17 said goes. Generally as long as they're all roughly the same then it means you've no dodgy rings/head gasket/valves etc.
