If I learned one thing this past year about engines is that "less is more". If you look at the first 10 R Series engines we are shipping they are R409s and few R360s. The problem is for every customer I have for these performance monsters I have many more that told me when/if we ever apply this tech to the 320 to call them. Well, the phone is going to start ringing!
Andrew and I have gone ahead and pulled the trigger. As I write this post our factory that produces the AX50 cylinder is building up the tooling for the AX40. While this will share all we have learned building the AX50 for 360/409/540s are planning on taking advantage of a few "tweaks" as we build up another set of tooling for this cylinder.
What we visualize is the ability to convert any wide deck 320 engine into a 335cu in, light weight wonder. If Andrew's projections are as spot on as they were on the R360, we are expecting between 170-180hp, same improved cooling, and unleaded fuel compatibility all for scant 225lbs…
We are not sure if this will be available through Titan as of yet but initially we plan on offering these as part of our ACE overhaul upgrade program. I have been running the numbers and feel as part of an overhaul of a 320 the cost to upgrade to a 335 will be in the low 20k's.
Here are some renderings of the 335 with our new sump and pressure recovery plenum.
This pic shows the inegrated fuel injector rail.
Note the AX40 plenum can accept either updraft or forward injector servo. Andrew spent many hours getting the flanges in the same position as a stock engine while still creating the area inside the plenum.
This version should come in around 225lbs!!! That is not much more than the Lycoming 233@115hp
