HOW OUR SKILLS BENEFIT YOU

Honestly advis

ing our clients has lead us to develop the knowledge to help you whether you’re flying an early model 35 or a hot new G36. We are the only manufacturer of tip tanks offering a large gross weight increase on the model 36 Bonanza airframe, giving you a 4010 lbs gross weight to work with for fuel or additional payload with our popular Genesis package. Genesis includes the IO-550B engine (or TSIO-520UB for the A36TC), enhanced engine cooling and the safety of gap seals. You can even specify the optional V/Gs to assist with slow flight at the higher gross weights. We are proud that D’Shannon is also the approved source of Tip Tanks for the Hawker Beechcraft Service Centers’ Bonanza XTRA program. With new management, we continue to develop new products and re-release products that were discontinued in the past. All of our D’Shannon products are made in our facilities in Minnesota, USA, and are STC’d and PMA’d. D’Shannon Aviation upgrades enhance the usability of your Bonanza, Debonair or Baron and will improve its value when it is time to sell. Realize the Potential of your Bonanza.

WHAT MAKES THE D'SHANNON AVIATION BAFFLE COOLING KIT SUPERIOR?

Our Baffle Cooling Kits Maximize all incoming air to provide optimal cooling for your engine. This helps in avoiding costly cylinder replacement & overall engine wear. Cool your engine and improve the longevity of the internal and external parts. This will allow you to realize the full potential of your engine.

Our baffle cooling kit is complete. It replaces the entire Beech baffle installation, both the metal and rubber seals, along with the mounting brackets and hardware. Everything you need to protect your engine.
We went beyond FAA requirements and conducted flight-testing in actual 100-degree ambient temperatures. Using the worst possible conditions defined by FAR standards, we have obtained unquestionably the most accurate possible cooling test results and they prove the effectiveness of D'Shannon engine baffles.
D' Shannon Aviation's baffle cooling kits are flying on thousands of Beech Bonanzas. Owners report remarkable improvements in the temperature of their engines.

*BAFFLE COOLING KITS BY D'SHANNON*
Your engine may be running extremely hot and you may not even know it. D'Shannon Aviation's custom Baffle Cooling Kits are designed to channel air flow through the cowling to properly cool your engine. D'Shannon Baffle Cooling Kits help avoid cylinder replacement by reducing valve, valve guide and overall engine wear. You'll improve engine safety while saving money and avoiding down time. Cylinder replacement is one of the first topics to come up when pilots and mechanics talk about engine operation. Many pilots say they can't get all the horsepower out of their engines because of engine temperature issues. Early cylinder failure and excessive operating temperatures are both symptoms of a mistreated engine. Your airplane's engine requires adequate cooling to run properly.

Those little "waves" and wrinkles often found along the length of the seal strips on improperly maintained baffles are escape paths for air your engine needs for cooling. D'Shannon cooling baffles will force that air where it's needed most - around your cylinders. Bryan Lewis, then President of Teledyne Continental Motors wrote in ABS Magazine: "The baffles and seals of your engine compartment are responsible for removing a heat load that is equivalent to the horsepower supplied to your propeller. Any disruption of designed cooling airflow can be a problem for cylinder life and should be corrected."

Engine cooling takes place by routing air through the cylinder fins and around accessories and the oil cooler. Take a peek at your current baffles. Leaking baffles show up as gray streaks along the upper cowl doors and the lower cowl. How many 'holes' do you see, where air is escaping without cooling your engine? Another test is to check the CHTs for all six cylinders. Don't be misled by a single cylinder head temperature reading. You may be redlining one or more of your other cylinders. Our baffle cooling kits give results that can lead to longer cylinder life, reduced maintenance costs and the ability to climb quickly to a cooler altitude without overheating your engine or running excessively rich fuel mixtures to compensate for inadequate cooling in climb.

*BAFFLE KIT FAQS*
How many hours will the installation take?
Roughly anywhere from 20 to 30 hours.

Do you offer support?
Yes, you can give us a call toll free at (800) 291-7616, or Here

Who can install my Baffle Kits?
Anyone can install the Baffle Kits, but an IA(Inspection Authorization) rating is required following the approval of a Baffle Kit installation inspection

Are your Baffle Kits FAA Approved?
Yes, we hold the supplemental type certificates "STC" along with a FAA parts manufacturing approval(PMA).

Improved Power Output
D'Shannon Aviation's High Performance Exhaust System is tailored to fit your baron and gives you:

Increased power with each stroke.
Reduced exhaust back pressure for more efficiency.
A cooler, denser fuel/air charge.

D'Shannon's High Performance Exhaust System is fully STC'd and PMA'd.

Cooler Operating Temperatures.
Our exhaust offers improved crankcase evacuation and ring seating, providing cooler operating temperatures. Cooler Engine = Increased Performance

* New Design *
Automobile designers and hot-rodders have known for decades that tuned exhaust creates a more powerful, more efficient engine. But factory aircraft exhaust systems have not had the advantage of tuning. D'Shannon can fix that on your baron's engine. A tuned exhaust reduces the pressure at the exhaust port just before the exhaust valve closes, to a level below the pressure in the intake manifold. This reduction must be precisely timed to happen during the overlap, the brief period when both the exhaust and intake valves are open. If tuned properly, each exhaust pulse creates a wave that pulls the next exhaust pulse along. Thus, the spent exhaust gas is not only pushed out by the piston, it is pulled out as well. This means a fresh fuel/air mixture is drawn into the cylinder while exhaust gases are simultaneously removed. The denser charge of fresh, cool mixture, free of residual exhaust, results in greater power output.

* True High Flow Exhaust System for the Baron *
Tuning an aircraft engine’s exhaust is easier than tuning a car or off-road engine because an airplane's engine normally operates over a narrow RPM range. Airplane exhausts aren't generally tuned, however, because space is limited under the cowl. In most cases, a tuned exhaust header requires longer runs with engineered bend radii to properly perform. D'Shannon's engineers have solved the problem and provide a custom-fit, fully tuned exhaust for Beech barons. D’Shannon Aviation's High Performance Exhaust: More power and efficiency for your baron!
