Hello listers,
I found this info in my notes:
>From April 1996 issue of Classic Cars
Compression Ratio = (Cyl. Pressure - 19.7)/14.7
likewise,
Cyl. Pressure = (Compression Ratio * 14.7) + 19.7
This yields the following values for TR6 engines with stock
compression ratios:
1969-76 PI Compression Ratio = 9.5:1 Cyl. Pressure = 159.4 psi
1969-71 Compression Ratio = 8.5:1 Cyl. Pressure = 144.7 psi
1972-73 Compression Ratio = 7.75:1 Cyl. Pressure = 133.6 psi
1974-76 Compression Ratio = 7.5:1 Cyl. Pressure = 130.0 psi
