Result of case study 2 system showed no increase in pressure drop and no
sign of turbine performance degradation. The
Initial pressure drop was reduced by more than 50% turbine with the existing high velocity system
applying the new filtration system, from 996 Pa suffered from a degradation of ~15% during the
down to 478 Pa. From the day of installation the same period, which lowered the output even more,
upgraded engine gained around 1000 HP more than compared with the improved and better performing
the one with the existing high velocity system. This installation (figure 5).
represents an increase in power output of ~6%.
After three months in operation the replaced intake
