Don't quite get where you are coming from with this...
33mins is actually quite good for ryanair... yes a 25 minute turnaround can be achieved but will be very very hard on a longer sectors such as Alicante where the re-fueling can take 20 minutes alone and the loading usually close to full each way! Dont forget turnarounds are calculated chocks on to chocks off not wheels down to wheels up...
Check some of the turnarounds at DSA, LBA and even STN their biggest UK base and you will see despite handling in excess of 20 turnarounds an hour at times on a daily basis they will rarely achieve 25 minute turns. Hundreds of factors can cuase this, just intrigued to find out what you mean
