The TEXTRON LYCOMING™ non-certified engine solutions for experimental aircraft include their standard experimental engine models and their premium Thunderbolt product lines, the company’s brand of high performance, built-to-order powerplants for these aircraft.Both are non-TSO versions of genuine Lycoming engine modesl, factory built and tested. In addition,TEXTRON LYCOMING™ lineup of engine kits is also available assembled from 100% Lycoming parts and tested before delivery.

Instead of being made on an assembly line, each THUNDERBOLT™ engine is factory hand-built and further customized & personalized through the selection of several popular options of fuel systems, ignition systems, performance enhancements and finishing options. Also, most of THUNDERBOLT™ experimental engines contain performance-enhancing modifications such as high-compression pistons, cold-air induction, and electronic ignition designed to increase horsepower and flight efficiency. All engines feature a balanced rotating system within 0.5 gram (connecting rods, pistons, piston pins), ported and polished cylinders, and customized paint options. 

The TEXTRON LYCOMING™ THUNDERBOLT™ engines are offered in Signature, Extreme or Competition series and cover the full spectrum of Lycoming familiar O-235, 320, 360, 390, 540 and 580 cubic inch models, although the IO-390 and IO-580 are the most popular.

Of the engines offered, all use parallel valve cylinders except the 390 and 580, which employ angle-valve cylinder heads. That makes them more efficient and powerful, but also heavier and more expensive.

235 and 320 Series include four-cylinder engines with models producing up to 125 hp at 2,800 rpm and 150 or 160 hp at 2,700 rpm respectively.

360 Series includes four-cylinder engines producing 145 to 210 hp. They are extremely popular due to their rugged reliability with smooth performance. Respective Lycoming’s 390 Series four-cylinder engines produce 210 hp at 2,700 RPM.

540 & 580 Series  are powerful and durable six-cylinder engines. Those in 540 Series produce 235 to 360 hp at up to 2,700 rpm with their counterparts in 580 Series producing 315 hp at 2,700 rpm with reliable direct drive and excellent power to weight ratio.
