If you control the mixture, spark, and temperature, the stock cast pistons can easily take 16 psi boost
* Never let A/F mixture go lean. 12:1 for best power, 14:1 for cruising
* Never let spark advance cause detonation. Mechanical spark advance needs tight control
* Inlet temps kept down to where detonation does not occur. Cold air intake helps along with either moderate boost OR adi (water/alcohol) injection
