998s/996r/998r engines Anyone had the cams dialed in and the squish set on one of the above? I have been told it will make big difference??doesn't that depend on the tolerances yopu have been lucky or unlucky enough to get when your engine was built at the factory?? Any other minor tweaks that get the best from the motor? I'm interested to make the best of what I have got already, not bolting on big cams, head porting, big bore pipes (already got open cans) TIA Ray |
