O’DONNELL SUPER SPORT .21 ENGINE

 

O’DONNELL SUPER SPORT .21 ENGINE

 

Sure to be the engine choice of dominant drivers!

 

Designed in the USA by master engine tuner Steve O’Donnell, the Super Sport .21 is the pinnacle of 1/8 scale nitro racing!  It’s a shining example of the “clean sheet” concept – a fresh look at engine construction and components, with nothing borrowed from existing technology.  Only state-of-the-art machining and materials have gone into producing the Super Sport .21. The engine features the original O’Donnell-designed “big head” machined aluminum heatsink head, dropped down low for a better CG. It’s the engine that top-level racers will be asking for!

 

  • The crankcase, cylinder sleeve and piston materials are optimized for uniform expansion to improve durability and reliability
  • 4-port ABC cylinder
  • Balanced Max-Flo™ crankshaft with Class 5 precision bearings
  • Machined 7075-T6 aluminum con rod with double bushings
  • Unique, compact 40spring header attachment design
  • Includes a high-performance O’Donnell #99 glow plug

 

The carburetor on the Super Sport .21 has all of these advantages:

  • Aluminum body
  • Thermal insulating sleeve that prevents vapor lock
  • Low- and high-speed needles with double O-rings on both
  • Hard anodized slide barrel
  • 7 mm and 8 mm restrictors included

 

Specifications:

• Practical rpm range: 3,000-42,000 • Output: 2.7 hp @ 36,000 rpm
