I was wondering if there is any way of measuring compression ratio in the Tibby motor.Since my car is the 1.8Litre i do know the compression ratio is 10:1,but when i did my cylinder head work last year i was wondering how much was actually shaved off the cylinder haed.I do recall the guy saing he just skinned it just to clean the surface area.But he could off cut more off<img src=/images/forums/snitz/eek.gif width=15 height=15 border=0>
I would like to know how to measure if because i want to run my Turbo safely.I dont want to run 10PSI then BOOM there goes my motor cause the compression ratio is TOO HIGH.Any help would be appreciated Thanks in advance<img src=/images/forums/snitz/finger.gif width=33 height=15 border=0><img src=/images/forums/snitz/finger.gif width=33 height=15 border=0>

2uniq,
You need a compression tester to start with its just a pressure dial that has a fitting to fit the spark plug hole. From there you can get a reading of your cylinder pressure and then there is a formula for comression ratio.

2 Uniq -

I have a little app that calculates the CR for you, all you need to do is enter the required values. Unfortunately you would need to have certain measurements in order for this to work.

Maybe this will help you, I can mailit to you if you like. Send me your mail address.
