Power 90!

If you are tired of expensive overhauls, frequent fuel nozzle cleanings, hot section inspections, and the
M.O.R.E extended TBO program then LoneStar has the answer!

The Power 90 is an FAA approved King Air 90, A90, B90, C90, C90A*, C90B*, and soon to be E90* conversion from the original Pratt and Whitney 550 shp engine to the more powerful 751 shp Walter M601E-11A . (*When conformed)

This basic Power 90 conversion includes two factory remanufactured Walter M601E-11A engines and two factory remanufactured super quiet Avia Hamilton V-510 five blade propellers. New engines, new Avia V-510 Propellers or new advanced technology Hartzell four blade propellers are available as an upgrade.

With our conversion you will climb to higher flight levels in much less time and cruise at greater true airspeeds. That adds up to more miles covered per hour and puts you above the weather on far more trips.

The average price of Walter overhauls cost much less than comparable Pratt overhauls -- as much as $75,000 less!  Additionally, the Walter
M601E-11A requires no expensive hot section inspection at mid-life saving as much as another $50,000. Walter engines are engineered to make "rated power" all the way to overhaul. Try getting that guarantee from other engine manufacturers!        

The "slinger ring" fuel delivery system is another major improvement which means no more expensive fuel nozzle cleanings every few hundred hours. With the Power 90 conversion you will save thousands of dollars on fuel nozzle cleanings, hot sections and engine overhauls.
