"Long climb will be forgotten"

Today, I had my first fly.  Seems to be great!  Now, I should check Gami-Injectors for not too different fuel-flows.  But Power is incredible.

Yes, it has a lot of snork. +20kn speed, increased climb rate from 800 to 1100ft/min...  Great deal.

"Pilotenservice Rieger" in Vilshofen, my Maintanaince Station in Bavaria will send back the core-parts in the next few days.  Lets see what future brings.

Wish you best regards.  Long climb will be forgotten.

Now I fly many hours with the intercooler and 220hp kit.  My Arrow makes fun.
Last time, I made a performance-test in FL160.- 190kts @ 75% power.  Like a Mooney but with more space inside.  You should make more advertising for your products.
Happy to did the rebuild.- Really.

Wish you a good time.
With best regards from Austria,

I have your Intercooler kit on my Piper Arrow VH-LZZ here in Australia, and it works very well indeed. We have seen 178 knots at FL170 which is not too shabby for a little old Arrow.
- Ian Anderson

I've been flying a Piper Turbo Arrow III for about 10 years and have been very pleased with the benefits of the Turboplus system installed.  I can usually run about 2 inches less manifold pressure and still obtain the same power level due to the cooler air going into the cylinders.  The temperature sensors make it easy to decide just how much to reduce the MP setting.  The 220 horsepower STC really gives great performance.  A friend I was giving a ride who had owned a normally aspirated Arrow for many years commented right after takeoff, "Boy, this Arrow has a lot of snort!"

When I bought the Arrow it had about 1600 hours on a Factory Remanufactured engine and I was able to get 2200 hours on the engine before rebuilding, which for the Continental TSIO-360 is quite a feat. I am very glad the previous owner had decided to install the Turboplus system as I have been the beneficiary of the performance and long life it adds to the airplane's engine.

The Turboplus Piper Turbo Arrow intercooler system

The Turboplus Custom Designed NACA Duct for your airplane provides the most efficient airflow systems to your Intercooler assembly and to the turbocharger. The direct airflow system into the intercooler are proven to be the most effective and efficient way to supply ambient air right at the intercooler installation.  NACA ducts are used worldwide in passenger jets, NASCAR, high performance automobiles and in the aerospace industry.

The Turboplus Piper Turbo Arrow intercooler systems provide ram air through their custom designed NACA ducts, for both intercooler and induction systems. One NACA duct directs ambient air through their custom designed airbox (with Auto Air Door) directly into the turbocharger.

The Intercooler NACA duct directs ambient air through their custom designed plenum mounted to the intercooler assembly. The NACA ducts create no drag. Turboplus Aircraft Systems, Inc. is the only general aviation aftermarket intercooler kit manufacturer to offer a Five-Year warranty on their intercooler system.

Turboplus Aircraft Systems, Inc. will ship your order to your home, business or any FBO shop of your choosing. Don't fly to us when we can ship to you.

Piper Arrow Turbo Mods

One of the reasons for the Turbo Arrow’s recent reliability may be the aftermarket mods available. Two are significant: intercoolers and an automatic wastegate. Turboplus offer intercoolers. At 12,000 feet, the Turbo Arrow has a fairly-low critical altitude—the max altitude at which the engine will develop its rated horsepower. Owners say they get a higher critical altitude with the intercoolers, along with lower operating temperatures.

It is highly recommended:
To record the critical engine altitude, oil and cylinder head temperatures and fuel flows at given power settings before the intercooler installation. After installation, another “flight test” ensures that engine and aircraft performance adhere to Turboplus Aircraft Systems, Inc. high standards. Post modification flight test data provides a direct "Before and After" comparison of the dramatic improvement in aircraft performance and engine operation. For your convenience, we supply the pre-flight and post-flight performance documents.
