a local friend run's 12 psi on an otherwise stock engine (only the injectors have been changed to protect the engine)ohh yeah ,forgot 2 .015 copper gasket spacers where used with the head gasket to get the compresion down to 8.5-1,the cost of milling and rebalancing the pistions was to high,considering the inherent weakness of the factory pistons ,also milling would only serve to make them weaker at the dish
to top that ,2 passes where made with the boost controller set to blow at 15 psi and could not detect knock(on 98 pump gas with one can of super 104 octane improver)
he is using a converted apexi SAFC and MSD dis4 ignitionw/boost retard
BUT THE ENGINE IS STOCK(sort of)
later
