The Hawk 100R has, what we believe, the fastest spool time on the market. Factory settings for the Hawk 100R is around 4 seconds from idle to max power. However you have the possibility to change the setting for times down to around 2,5 seconds. This gives you the spool time from half throttle (aprox 50N of thrust) to maximum throttle in around  half a second. This is  a result due to very high combined turbine and compressor efficiency.
