Just need to share the news in Commander land. I have been working with Dick 

MaCoon  and Arnold Blankenship of Firetruck Aviation in Centerville Tennesee 

to put together an updated turbocharger conversion.

Commander 500S N210HD sports 4 RayJay turbos, Inconel wastegates, updated 

actuator system (no cables) linear electric actuator, electronic wastegate 

controller with manual override.

Relocated oil cooler.

No scavange pumps, improved gravity drain system.

A general clean up program to improve maintenance access and reliabilty.

Final STC certification details are pending but she will fly legally with a 

DER's 8110 form.

System is based on the original RayJay STC and MR RPM improvements. Test 

flights are scheduled for next Wendsday.

STC will cover 500B,U,S. and will feature a gross weight increase.

Bragging a bit but she will have all of a freight dog's maintenance 

improvements, my contribution. She only makes a living when she flys. She 

must be reliable and maintainable.

Contact Arnold or his most capable wife Charlene at 931-729-0007. Arnold is 

the holder of the MR RPM STC's and tooling.

Or myself Mike Floyd 509-886-1036

Hi Mike,



Quick question: I have a 500B with the original rayjay system installed 

(electric wastegates). Is this a complete new installation, or is there a MR 

RPM "upgrade" available? Additionally, can this package be offered on the 

newer "wide-deck" IO-540's? I'd like to switch to those engines at some 

point.



Also, can you share some information on the cost of the conversion/upgrade?



Thanks,



/John

Sounds perfect!  More questions:



How does one over ride the electric turbos without cables?



This must be full-time turbo-normalization, right?

No the later wide deck engines are not supported thank Lycoming for that. 

The original narrow deck IO-540s are supported. And so are the original 

RayJay installations. No price info yet but if you have the system intalled 

the upgrades are available.

The electronic wastegate controllers can be overridden by the manual control 

switches.

Mike,



Thanks for the response. I'm excited to see what the finished product looks 

like.

The electronic control box for the linear actuator is turned off by a switch 

in the cockpit and it reverts to a manual open, closed switch system.

So, in the event of power failure or simply circuit fault, does the waste 

gate fail to full open or does it fail to present position?

It fails to the present position in either instance. It would then be up to 

the pilot to control MP. using the throttle.

Mike,

Were you able to work in the intercoolers.  When I was talking to  

Dick, he had designed the intercoolers to be under the cowling with a  

little scoop and the scoop for the oil cooler would be behind the  

firewall in the wheel well.  Has that configuration  worked out?



Could an existing conversion add the intercooler and oil cooler?   

Those two thing would help keep the engine cooler?



It is great to see those STC in hands that know what they are.

That was the answer I was hoping for!  Sounds like yet another well 

thought-out Mr. RPM innovation.



OK ... more questions.  Hope you don't get annoyed, but I've been waiting for 

this news for years.



Does the package use an updated EGT or TIT?  (Don't get started on that 

thread again, lads.)



I'm sure the STC would not specify a particular EGT or TIT gauge (so the 

installation leaves it to the owner's discretion) but am curious if Mr. RPM is 

advocating one reading over the other for the updated equipment.



Thanks!

Yes the oil coolers have been moved behind the firewall. Works out well. No 

development of the intercoolers yet.

The existing conversions could incorporate the oil coolers.

Between relocating the coolers and cleaning up the ducting and turbo oil 

system it makes the engine compartments much easier to work in.

No the STC will not have an EGT or TIT system specified. No I have never 

discussed this with MR RPM. Both systems give you the same basic 

information, where is the engine operating in relation to peak temp.
