Roy LoPresti spent decades making airplanes. Now LoPresti Speed Merchants makes airplanes fly faster. As much as 25 m.p.h. faster -- without using more horsepower. LoPresti Speed Merchants' drag-reducing designs have earned awards and accolades from pundits and pilots all over the world.

In 1991, after 40 years of lending his talents to aviation giants such as Grumman, Mooney, Beech and Piper, the legendary engineer formed LoPresti Speed Merchants, located in Vero Beach, Florida. LoPresti Speed Merchants holds more than 40 Supplemental Type Certificates (STCs) and Parts Manufacturing Authorizations (PMAs) from the FAA, plus patents and copyrights.

LoPresti designs induction systems that synchronize propeller pressure pulses with engine intake strokes to provide improved engine "Breathing," which produces more power. Fully adjustable cowl flaps help fine tune the cooling air passageway geometry to provide near optimum cruise and climb cooling. Hydraulically sequenced nose gear doors ensure that the doors fit extra tight to eliminate leakage drag.

LoPresti Speed Merchants manufactures mod parts from the ground up, using carbon and fiberglass and hundreds of molds. Skilled technicians turn the engineering drawings into the three-dimensional molds used to create the finished parts.
