True in both the 5k and the 200 Bentleys.
I noticed another error in this section...
5k Bentley
MC Engine compression 8-11 bar (116-159.5psi)
6.5 bar (94.3 psi) wear limit
200 Bentley
MC Engine compression 8.5-12 bar (123-144!!!!!!psi)
6.5 (92 psi) bar wear limit
Let's try 175 psi for that 12 bar, not 144 and 94.3
is more believable for 6.5 bar, not that a couple of psi
makes any difference!
So, we can probably assume that the lower numbers (116 to 160)
are for the earlier MC and the higher numbers (123-175) are for
the 89.5 on MC.
Orin.
