Spool up time on the JT8D (727, 737, etc) is 8 seconds or less from some
minimum EPR to some maximum EPR but quite frankly I had those numbers
memorized from forty years ago.

The A-319 has either CFM-56s or IAE2500s, both of which go from idle to max
power in 3 seconds, and less time from flight idle. During a routine
go-around, approach thrust to MCT, power is available with little
discernable lag.
