With the Bing this would probably be a big problem as the Bing likes a smooth air flow. The TBI 40 may tolerate it but putting something like this after the carb would seem to be much more desirable. In the 3300 design, there is very little room to do this but that is what I am working on. Of course, the Tornado claim of doing anything with today's electronic fuel injected auto engines seems unlikely. All the fuel mixing takes place right at the intake valve. The Tornado claims to fit in airways between 2.5 and 3.75 inch dia. The outlet side of the carb is about 1.6 inch dia. It might still be useful to start with this thing and modify it to fit. One thing I did find is that simply making the air rotate does not help, it rotates some very lean air into cylinder 6 although it helps with the others. It would be really nice if the manufacturer (Rotac or Jabiru) would do this right and design the required coupling on a test stand. -------- Mark Hubelbank N708HU CH601XL Jabiru 3300 Rotec TBI 40 carb Sensenich ground adj prop. 28 hr TAF Read this topic online here: http://forums.matronics.com/viewtopic.php?p=268668#268668 ________________________________ Message 2 _____________________________________ Time: 10:19:05 AM PST US Subject: Zenith601-List: Re: CH601XL and Jabiru 3300 Performance From: "Stephen Smith" Mark, Thanks for the pictures. It is very helpful to see your fabrication. Lucky for me I have no interest in dual throttle cables. The extra friction looks like a big negative.
