Thunderbolt engines are non-TSO versions of factory models,
and much is demanded of them. All of the engines in the Red Bull
Air Race series were Thunderbolt models, and many top airshow
performers use them, too.
The engines are more evidence of the ongoing shift toward cusAN ENGINE GETS STEAM CLEANED (below left) before
Thunderbolt technician Paul Zener puts it in an
tomization and personalization in general aviation. Thunderbolt
industrial dryer (facing page). The final step before
engines cover the full spectrum of Lycoming models from the fourdelivery is exterior paint-and highly stylized colors
cylinder O-235 to the eight-cylinder IO-720-although the IO-390
and appearances have become a Thunderbolt
hallmark.
and IO-580 are the most popular. Each Thunderbolt engine sells
for a $4,000 premium compared to those built on the assembly line.
Lycoming expects to build more than 114 Thunderbolt engines this year, up from 74 in 2019.
Van's Aircraft kit builders are the largest group of Thunderbolt customers because the Lycoming IO-390 is the engine
of choice for the newest RV-14 kit airplane. Extra Aircraft in Germany uses both stock and Thunderbolt engines for its
Unlimited aerobatic airplanes.
All Thunderbolt cylinders are ported and polished to increase efficiency, and pistons and connecting rods are balanced
to within a half gram for smoothness. Lycoming says there's no empirical data to prove Thunderbolts are more reliable
than the company's stock piston engines-but as evidence of their reliability,
Thunderbolt managers point to the fact that none of the Red Bull Air Race
engines failed during the many hours of torturous use they underwent during
years of demanding competition around the world between 2003 and 2019.
"The engines themselves held up just fine," Schappell said, "and many of
the air race teams used the same engine season after season."
THE TEST
The test to join the Thunderbolt team isn't written down-and it's not
multiple choice.
The test to join the Thunderbolt team is an untimed, open-ended effort in which the
applicant is given a box of parts and a manual and told to build a complete engine.
