The TBI-40-S, utilizes a spigot style round mounting system typically found on the Jabiru 3300 engine. A rubber coupling is used for securing the TBI and allows for 360 degree mounting. This can also be advantagous for custom mounting design as seen on the single Rotax 912 conversions which have been popular in recent times.
The TBI-40-S is best suited for engines 90-150 HP.
RIGHT ON!!7 September 2018First flight of my Sonex with a jabiru 3300 and a Rotec TBI went off great!!! This engine NEVER ran like this!!! Having had some near deaths with the "brand A" throttle body and forever trying to get it to run sort of alright...the Rotec was awesome right from first start and gives me a solid 100 rpm gain on climbout with lower EGT (1100 tops)! I'm making significantly more HP and its smooth in every rpm range. I couldn't be happier with the choice I've made. I'll send some pics when the cowl comes off and till then enjoy a brief walk around!! Dana Thurston USA
Jabiru 3300. Up 450 RPM!3 July 2010I ﬁtted a Rotec TBI-40-S to my Jabiru 430 about 8 months ago and while at it I also ﬁtted a new Sensenich prop to replace a damaged one. The replacement prop was identical to the previous. on ﬁrst take oﬀ I was very surprised to observe the revs had increase dramatically to 3200 rpm when on the previous Bing set up would deliver about 2750rpm. That’s a big jump in performance, some 450rpm! I would have no hesitation is recommending the TBI for the Jabiru engine, its brilliant. Paul please feel free to forward my experiences to any potential customers you may have, you can also give them my email should they wish to discuss any aspect of the TBI. Thanks again for wonderful product. Regards Bruce Knowles
