Ok, Based on a roots supercharger filling the cylinders of an 8.3:1 1275cc, no (limited) after(inter) cooling, what gap specs would be best for cast pistons? Im expecting to be running rather hot. |

Dyno man was not BS He said I know what a good standard one does and dont know my dynoes accuracy . He said yours does double.  Was 9 psi boost with a RAMS head .Had to pull it down once to get CR better was young and CCed nothing
