Megas used to be great, bit more recent experiences have been bad with the ring lands falling apart at anything over standard boost. In the 13's at last!.. Just |

if you have an engine that is detonating and you damage a piston it is not the fault of the manufacturer. ANY piston could be damaged due to incorrect running of an engine..

Currently got some plus 20 OE Metro turbo pistons fitted. The rings footed were obtained by matching sizes and spec with known ring sets, took two sets to build a complete set for them one set was for a plus 40 piston Own the day

could it be possible to get a measurable amount more ring tension to the bore with a ring that is reduced in size more than normal? |

More friction more heat. Remember that the highest losses due to friction is because of ring tension. If anything you should be trying to reduce this friction not increase it.

My point, which I am sure you appreciate, is that if you squeeze a split circle down in diameter it is then no longer a circle. |

Dimensionally the rings were identical. Shape wise the rings were identical the only difference was that there was more material in the circumstance due to the fact as mentioned above it was for a plus 40 piston. Own the day
