Inliners International Forums General Discussion Hi Performance 'safe' compression ratio on pump gas, 292.

A 292 will have the same 8.00:1 DCR with the following:
12.00:1 CR, IVC 83° ABDC
11.00:1 CR, IVC 75° ABDC
10.00:1 CR, IVC 64° ABDC
9.00:1 CR, IVC 48° ABDC
8.00:1 CR, IVC BDC
These tunes will have vastly different power, torque and knock resistance.

8.2 is not the limit until all other variables are factored in.
