• Windshield Wedge
• Belly Fairing

A drag reducing fairing, (Windshield Wedge), located on top of the baggage compartment extending from the firewall to the leading edge of the windshield. The windshield wedge reduces drag and makes the windshield area look very much like the Malibu’s windshield area.

A fairing below the baggage compartment (similar to the Windshield Wedge) reduces the drag caused by exposed structural longerons on the stock Lance/Saratoga belly.

One short and two long rigid carbon nose gear doors replace the two short stock nose gear doors. The stock nose gear door support structure is totally replaced with a stronger and stiffer structure. A new hydraulic actuator and sequencer keep the nose gear doors sealed tightly during cruise flight.

The cowl is manufactured in left and right hand halves. This arrangement eliminates the customary split line often found running through cowl inlets which leads to chips and cracks in the inlet contours. LoPresti’s left/right cowl halves eliminate this cracking problem.

The stock cooling air exit in the belly has been eliminated. All the cooling air exits through a cowl flap controlled passageway. Much better engine temperature control is provided by a cowl flap that can be positioned and locked in any position from full open to full close.

Two new and larger oil coolers with new firesleeved oil lines are included. A new induction system inlet is strategically placed off center to intercept a pulse of air from each propeller blade passage at the right instant. The resulting pulses arrive at each cylinder’s intake valve when the valves are open. The SynchroPulsing has been optimized for a three bladed propeller, but also works with a two bladed propeller. This Synchropulsing technique provides more manifold pressure and therefore more horsepower, and more speed.
