SDS wins 2018 Reno Sport Class Gold Championship!

Andrew Findlay broke the amazing 5 year winning streak of Jeff LaVelle in Sport Class at Reno 2018. 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.

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.
