Compression ratio too high?

[GTRMikie]

Is a compression ratio of 11:1 too high for a road going 998 with a Kent 266 cam?

If you intend running a dizzy and 95-Octane unleaded - Yes. If you run programmed ignition it would be fine.

If you stick with a dizzy - can you even afford to run on it on 97-98-99-Octane super juice?

Put a 286 in and it should be fine

My other car is 5.7 litres of Ultima GTR which runs on Shell V Power, so the mini wouldn't present too much of a struggle in comparison!

11.1 is ok on 97 fuel stop back the advance mecanisim in the dizzy increase the tension of the bob weight springs and go kick some arse
