M1 Cooling Kit - N637BE

Today I flew back from SJC (San Jose Intl) to FNL (Fort Collins-Loveland) at FL250.  My Malibu has the TSIO550 engine mod,  it's  High Speed Cruise is 32.5"Hg. 

In the past, I was never able to run at 32.5" manifold pressure above about FL220:  the cylinder head temps were right on the red line on my analog gauge, so I had to reduce power to approx 30"Hg in order to keep the temps down.  Well, today, I climbed directly from Sea Level to FL250 and set the plane up for high speed cruise at 32.5" Manifold Pressure.  I leaned to 50 degrees rich of peak at 22gph fuel flow.  This is as fast as my Malibu can fly... that's why I bought it!

 Just as you advertised:  my cylinder head temp was almost exactly 40 degrees cooler: top of green!  Wow!  At these settings, N637BE was flying at 238ktas!  Outside air temp was -20C (somewhat warm), so at -40C, I'm sure I'll see 245ktas!  Malibus aren't supposed to fly that fast! It's absolutely amazing what a few extra horses can do in the thin air of FL250!  These numbers were verified by the Garmin 530, the air speed calibration ring, and my independent calculations.

 You have got yourself one happy customer!!!

 THANK YOU VERY MUCH!

M5 Conversion - N135US

"My 1987 Malibu had already been converted to the 550C engine, but the plane still had major departure issues until I took advantage of Chad Menne's propeller conversion.

Flying out of the hot Mid-Atlantic in the summer at Gross weight was uncomfortable at best.  The 550 engine was of great help, but the two bladed prop could not deliver the thrust needed. Chad's beautifully engineered conversion literally changed the aircraft. I no longer experienced the 80-110 knot sinking transition feeling, now the aircraft accelerated to Vy without a lag. The cooling mod allowed me to run comfortably in the low 300s, no matter what the temperature, ROP or LOP. The Hartzell is a real, fully tested and certified propeller, and as we have seen recently, the other conversion leaves a great deal to be desired.

This conversion is the first place I would put any money when considering an upgrade, it really makes it a new machine."

Malibu Maintenance - N14CX

"Hi Chad, Ketti, and Nathan, I want to express my heartfelt appreciation for the work you just finished on my Malibu with the TSIO 550C, and 3 blade. I arrived thinking I may have needed some cylinder work on the 720 hour engine. Once we started examining the cylinders, we found worn cylinders, rusted pushrods, pitted lifters, a sanded down cam, and enough other signs that we acknowledged a tear-down We decided to overhaul all six cylinders, and  rebuild the engine. You were able to get all this done in just 3 weeks, and that was for checking all the crankshaft, replacing the mains, cam, and essentially overhauling the entire engine, with a mixture of practical overhauled, and many new parts. Nathan put it back together like the master mechanic he is, and Chad test flew it, and you perfected the normal tune-up items. Matt and I flew it home Friday, and it ran the best it ever has. We were able to attain 214 ktas on 23gph, ROP, at FL160. At LOP, we were getting 200 ktas on 17gph. We were breaking in the engine. You not only found all the items on the engine, but, corrected 6 other important items that needed attention on the Malibu. After flying these PA-46's for 23 years, I can only say I am impressed with your work, attention to detail, overall knowledge of the engines, and airframe, and prices. You and your staff have a great attitude. Thanks, you are a real asset to the fleet."

M5 Conversion - N146ZF

"I love my M-5 conversion.  I've owned my plane for 6 years.  When I got it, I had my 520 rebuilt.  As it came time to rebuild it again, I checked out all options.  This option made sense on all levels.

 With 20 plus years of Hindsight, this is what the Malibu wanted to be in the beginning.  A little more engine with more cooling and the best prop on the market.  The team at Malibu Aerospace has taken the best of all options.  The M-5 Conversion is the whole package.

After the conversion, we stopped at Malibu Aerospace to have them review the installation.  I've had a difficult year with my old engine, but having them spend a day under the cowling gave me the confidence I needed in my plane. 

 These guys know Malibus."
