[QUOTE="Jay@Lamotta, post: 462518, member: 9930"] The problem is you can't run much timing with the high CR. The closer you can stay to stock timing the better. Starting the fire late will give the piston more time "to run down the bore" away from the peak pressure in the cly 12-14 after tdc. But I think camming will have to be addressed if you pull that much static out and it will make it lazy down low. Most tuners will tell you that 2 degrees it worth 30-50whp(with FI). Static compression is worth about 10whp per point. Look at static on any high FI car factory or not. When formula one had boost the CR were 6.7 to 7.2. I know this is extreme example. I'm sure the skyline.supra.911turbo and other OE turbo cars have a low CR prolly 8.1 . [/QUOTE]
