SDS wins 2018 Reno Sport Class Gold Championship!

Andrew Findlay broke the 7 year winning streak of Jeff LaVelle in Sport Class at Reno this year. We are so proud of Andy and his team and honored that they picked SDS for their EFI and ignition control. Great guys to work with! This is our second Reno Sport Class win after the first ever EFI win back in 2010. Andy's race average on Sunday was 402 mph with one lap in the 408-409 mph range.

Video links:

Please note that all SDS electronics operate on 12/14 volts. 28V systems must use a separate 12/14V system or a step down power supply to power the SDS and fuel pumps.

We can now supply quality, fan cooled 28 to 14V power supplies rated for 30 amps. Two are required for dual ECU systems. $165US ea.

Please be aware that there are numerous variations among engines of the same type. Some parts may not fit or may have to be modified in certain cases.

Reno 2017

Andy finished towards the front in several Sport Class races this year and showed tremendous speed in the Gold Race, shadowing the race winning Glassair of Jeff Lavelle for a couple of laps before bumping the mixture knob out of position which cut the engine out for a moment, unfortunately ending his race. With the SDS EM-5 6F system installed, the airplane was much faster than last year, clearly making massive hp in the Gold Race running full boost pressure. He'll be back next year to show what the Stihl Lancair has got. SDS worked flawlessly in the race.

Four Cylinder Continental Engines

Along with the six cylinder engines, we have done a number of smaller Conti engines, the first back in 1996. Mark Snow was an early SDS user on his C-85 powered Dragonfly, accumulating over 750 hours. Justin Mace had 350 hours on his SDS equipped, O-200 powered Dragonfly.

Fuel and spark control kit for O-200. Wiring harnesses, fasteners and plug wires not shown. $4611US for single ECU system.

See the article in the June 2018 Kitplanes magazine on our O-200 system

O-200 Installation manual

Bert Caron is doing an SDS EFI installation on an O-200. With some fin mods, he was able to fit the Lycoming style injector bosses into the Continental heads.

Mar. 15/17. We acquired an O-200 for jigging and development purposes. This was used to design and some new CNC'd parts to make the installation easier on these engines which resulted in our new EFI kit shown above.
