Guest rv6ejguy Posted December 3, 2013 Share Posted December 3, 2013 I'm Ross from Calgary, Canada. My background is 35 years in aviation and the auto racing industry. I've been flying a turbo Sube powered RV6A for 10 years and am building an RV10 now. I'm the owner of Racetech Inc., manufacturer of SDS electronic fuel injection systems for aircraft and automotive applications for the last 20 years. Currently working on EFI kits for Rotax 912 and Jabiru engines. I've already learned some things here, looking forward to learning more from down under.

Old Koreelah Posted December 4, 2013 Share Posted December 4, 2013 Welcome Ross. Sounds like you have some experiences to share. Interested in how successful the Sube engine has been. No doubt you will get some enquiries about your EFI sysyems. I am aware of EFI being installed in some Jabs by an engineer who formerly developed such systems for a car manufacturer.

facthunter Posted December 4, 2013 Share Posted December 4, 2013 There should be some interest. Uneven mixtures are a common problem, which is more critical on an aero engine than a lot of other applications. Welcome to the forum ..Nev Link to comment Share on other sites More sharing options...
Guest Maj Millard Posted December 4, 2013 Share Posted December 4, 2013 Welcome Ross, I know of at least one Suby powered RV-6 in the area. I am a L2 maintainer here specialising in 912 maintenance. Very interested in hearing of your future developments with the 912 injectn system. Hopefully it'll be without some of the problems the 912iS is currently experiencing as teething problems. Looking foward to you future contributions.................Maj.... Link to comment Share on other sites More sharing options...
Guest rv6ejguy Posted December 4, 2013 Share Posted December 4, 2013 We've had 912 and Jabiru engines flying with our EFI since 2007 and 2008 respectively so there are several thousand hours of flight time on them now. The improved mixture distribution on the Jabirus over the carb setup reduces the fuel consumption noticeably for the same TAS. We actually supplied our first systems for two 3300 engines back in 2000. We have over 100,000 hours of flight time on our EFI on hundreds of different engines over the last 19 years so it's rather well proven. On the Subaru EJ22T, our company test RV6A has over 370 hours on it now over the last 10 years. It's proven reliable but we had to do a rebuild as the rings and valves were pretty tired at 358 hours. Total rebuild cost was under $1000 so it was pretty cheap flying. Link to comment Share on other sites More sharing options...
JimG Posted December 4, 2013 Share Posted December 4, 2013 Hi Ross, welcome to this site. Been reading your posts on HBA and Flysoob for many years now. To everyone else, Ross has been involved in a lot of redrive and cooling system research and testing for a very long time and in particular his P51 style cooling system on his company RV. Very impressive stuff and motivation for the more hands on homebuilder with auto engine conversions in mind. Check out the youtube clips of the cooling system build and testing, links are on his web site. Cheers JimG 1 Link to comment Share on other sites More sharing options...
Guest rv6ejguy Posted December 4, 2013 Share Posted December 4, 2013 Maj, I read with interest here and from reports in the UK that the 912iS is having some issues with rather low time and I was quite surprised after all the testing and development Rotax apparently did. Their system is extremely complicated which in my mind is never a good thing. Our electronics are much lighter, simpler, cheaper and far more proven as well. Diagnostics for sensor failures are right on the gauge head for the pilot to see in real time. We can suffer simultaneous failures of the MAP, CLT, and IAT sensors and the engine will continue to produce near full power. About half of our 912 systems flying are fuel only, retaining the stock ignition system, the other half use twin coil packs and upgraded alternators for the higher current loads. The new kits we plan to offer soon for the 912 will be fuel only as we saw no big gains in hp with computer spark control although there may be gains in fuel economy at altitude which were not able to test for at the time. BTW, the avatar shows our yellow factory RV6A test bed and the world's fastest (we believe) stock airframe RV7 powered by a Subaru EJ257 engine. Both are equipped with SDS EFI. Glad people here are interested in our projects. Seems like a friendly place. Link to comment Share on other sites More sharing options...
Hongie Posted December 4, 2013 Share Posted December 4, 2013 Gday Ross and welcome. I'm sure many would be interested in an EFI system for a 912 :) I actually looked at using a SDS system a couple of years ago to put in a mitsubishi pajero with a 4G54 2.6l petrol, but never went ahead with it.

Guest rv6ejguy Posted December 4, 2013 Share Posted December 4, 2013 Thanks for the warm welcome here everyone. We've supplied a fair number of aviation systems to Australia and NZ over the years. You guys seems to love aircraft just like me. We tried the 912 EFI kit back in 2007 but the world did not seem ready to embrace it. With the factory introduction of the iS this year, suddenly there seems like a lot more interest in fuel injection but I could be wrong again...

ave8rr Posted December 4, 2013 Share Posted December 4, 2013 Hi Ross, welcome to the site. It may be on your web site but what brand or type (belt/cog) reduction drive are you using on your Suburu engines? Cheers Link to comment Share on other sites More sharing options...

Gnarly Gnu Posted December 4, 2013 Share Posted December 4, 2013 Sweet Ross, the Jab engine is just pining for EFI. Heard good results from those that have already gone this way. Link to comment Share on other sites More sharing options...

Guest rv6ejguy Posted December 4, 2013 Share Posted December 4, 2013 Thanks again everyone. Mike, I run an M-300 Marcotte gear drive, made in Canada. You probably don't see too many around these parts. Link to comment Share on other sites More sharing options...

Many thanks Ross. Thought it might of been the one made by Autoflight in Hamilton NZ. This is used by a lot of the Gyro people. Cheers Link to comment Share on other sites More sharing options...
