| Hi Everyone,
|
|
| Here are some answers to the last two posts about the Merlyn conversion:
|
|
| Barry - 1525-187 is my plane, N222LE.
|
|
| STC SA01212SE - Merlyn Shrike 320 conversion and 7200 lb GW increase. In
| order to be eligible for this installation, the engines must have been
| modified under STC SE01211SE, conversion to TIO-540-AE2A(MC). This basically
| adds the turbo, exhaust system, and up exhaust cylinders. Also, the
| conversion requires Hartzell HC-C3YR-2UF/FC8468()-6R props (compact hub).
|
|
| This conversion basically takes the Malibu engines and lots of accessories
| such as the alternator, oil cooler, remote oil filter, pressurized mags,
| etc. and utilizes them in the Commander. There are lots of small advantages
| like the remote oil filter (oil change 20 minutes) and a vernatherm
| mounted in the cooler, not in the impossible to access oil filter adapter on
| the back of the engine. No engine mount changes are necessary and it also
| includes two Weldon nacelle mounted fuel pumps in lieu of the sump mounted
| ones. The nice part is the Malibu engines are very well supported so parts
| like mags, vacuum pumps, etc are readily available. The turbo system itself
| is very simple and it's designed for low maintenance. The wastegate is
| manually actuated but it is slaved off the throttle linkage. The first 75%
| of throttle travel doesn't move the wastegate but after that the wastegate
| starts closing. There is no wastegate controller to break and there is a
| massive pressure relief valve in the induction line so overboosting is
| basically impossible. The turbo is mounted up high so there is no need for
| an oil check valve or scavenger pump. The oil drains freely back into the
| case. It also comes with a really cool electronic tach made by Hickok
| (analog face, but electronic everything else). It runs off a Hall effect
| sensor on the mag so there is no tach generator to worry about and so far it
| is super accurate.
|
|
| The turbo operated best below about 21,000 feet although it will make 42" @
| 2500 RPM up to around 21,000 or 22,000. At that altitude and at full power,
| however, the wastegate is fully closed and I'm told the servo inlet temps
| start to rise. Pull the power back to 35"/2400 (climb setting) and the servo
| inlet temps come back down. I cruise at 28" and 2200 which is about 65% and
| it will maintain that well past 21,000 which is the highest I've flown it so
| far. 65% at 21,000 yields about 195 KTAS in my plane. Down at 12,000 -
| 14,000 the same power yields about 180 KTAS. Fuel burn at 65% is about 17
| GPH/side at 100 degrees ROP. I'm going to start experimenting with LOP but I
| was waiting for the engines to fully break in. Cooling is good, with all my
| CHTs under 410F @ 65% @ 21,000. CHTs are lower at lower altitudes.
|
|
| Note: The 320 conversion is technically rated to 300 HP continuous (38") and
| 320 HP (42") intermittent. I think the reason for this had something to do
| with not having to do as much flight testing for a 300 HP continuous rating.
| This is probably why the FAA didn't require a time limit on the 320 HP, just
| saying "intermittent" was enough.
|
|
| V speeds are a little different due to the heavier GW and higher power.
|
|
| Vso 62 KCAS
|
| Vs 67 KCAS
|
| Vmc 69 KCAS
|
| Vyse 104 KCAS
|
| Vy 110 KCAS
|
|
| As I mentioned before, there is also a STC to turbonormalize the
| IO-540-E1A/B5 (290 HP). I believe the same STC allows turbonormalizing of
| the IO-540-M1C5 to 300 HP if you have that engine. The latter also requires
| the compact hub props so if you have neither the M1C5 engine nor the compact
| hub props, it is an expensive way to add 10 HP/side which is why no one has
| done it so far.
|
|
| Hope this helps.
|
|
| Scott

I have a 1952 520 commander Serial number 39. Nice interior could use paint
but still servicable. Coming out of a 15000 dollar annual plus lots of
refurbish work about three years ago. New fuel bladders fuel senders and
gauge. new hydraulic hoses, most of wiring in the engine bays is redone, new
engine mounts. Too much to really go through. Contact me if you want more
information.

I am interested. Would you be able to create a speck sheet. If not let me
know what it has, the main things I need to know are engine SMOH/Year, Prop
SMOH/Year, TTAF, and Electronics....and of course where you are looking to
be on price...Please email when you can thanks again....
