[QUOTE="boomtube, post: 338484, member: 9215"] Well, for an approximation, you could use the Universal Gas Laws to compute for the change in chamber pressure because of temperature. Multiply the peak chamber pressure in absolute (peak pressure in psi + 14.7) times the two Absolute Temps (add temp F to 460) for the change. T2 (absolute temp in the second instance) ___ =x Psi (absolute) = absolute pressure change T1 (absolute temp in the first instance) [/QUOTE]
