Whirlwind upgrades available for your Turbonormalized Bonanza

Presently Available

The following recommended options have been developed by GAMI or Tornado Alley Turbo, Inc. specifically for the enhancement of the Whirlwind turbonormalized Bonanza. The STCs are completed and the installation of these modifications will significantly improve the aircraft's performance and efficiency as well as your value and enjoyment of this premier system.

• Composite Airbox

  

  Replacement of the metal airbox (behind the air filter) with a composite airbox allows significantly more airflow through this component and increases the efficiency of the turbo system. This installation is very easily accomplished in about 2 hours.
  $995

• Alternate Air Door Relocation (w/ Ice Detection)

  

  A previously issued service bulletin required the relocation of the alternate air door further downstream and to the left side where it is not subject to icing. The "old style" alternate air door was located in the metal airbox just behind the air filter. The newest style relocation is accomplished by the installation of a replacement induction tube located inside the left engine access door. The new alternate air door is more than twice the size of the old one, enabling you to maintain manifold pressure. Also included with this kit is an ice detection system, which comes complete with an indicator light that mounts on the panel. When the indicator is lit, you know you've got ice. It has proved to be very effective in our testing. This installation is very easily accomplished in about 4-5 hours.

• Rammer II™ Intercooler with Scoop Duct™

  

  The larger Rammer II™ Intercooler provides more cross sectional area for heat exchange, offers greater induction air temperature drop and reduced back pressure for enhanced volumetric efficiency. Aerodynamic and aesthetically-designed, the Scoop Duct™ provides unobstructed ram air directly into the Rammer II™ intercooler and accommodates the Boom Beam landing light. The combination of the larger intercooler with improved cooling air flow equates to cooler induction air temperatures for more power. Intercooler efficiency is improved 15-20% over the already efficient Rammer™ intercooler.

• Cooling kit for cylinders #2 and #6

  For improved cooling of the two hottest cylinders, we have designed and certified new, additional components to provide more airflow to the right places on those cylinders. This design is so effective that these two cylinders which are typically the hottest, will probably end up amongst the coolest. With improved cooling comes the ability to use more horsepower = speed. By reducing these cylinders' temperatures by 30-35 degrees each, we can increase the horsepower enough to gain 3-5 knots of airspeed. Installs in about 6 hours.
  

  • #2 Baffle Fix - $1,395.00
  • #6 Baffle Fix - $395.00
  • Both #2 & #6 - $1,695.00

• Cheek Plate Louvers

  

  Fully louvered cheek plates as are found on current model A36s replace older style "shark gill" style providing for increased airflow out and increased airflow in for reduced CHTs. This modification typically drops Average CHTs by 10-15° F. Must be sized to fit your aircraft.
  $2,500 (primed)

• Baffle Louvers

  

  Louvers located in the fuselage below and slightly aft of the cowl doors provide enhanced airflow through the cylinders for lower cylinder head temperatures. Originally installed on only the IO-550 systems, these louvers are now standard equipment on the "Whirlwind 520 system and are available for your Bonanza if not presently equipped. Installation takes approximately 8 hours.

• turboGAMIjectors®

  

  Improve the engine smoothness and efficiency by installing turboGAMIjectors® fuel injector nozzles to achieve improved fuel/air ratios. The benefits include more uniform EGTs and CHTs, smoother engine operation, the ability to safely run high power, lean of peak TIT for more airspeed and significantly improved fuel economy. Although most of the Bonanza turbonormalized family of owners have already made this simple modification, there are still a few who need to make this change. The installation takes only about 1 and 2 hours and the turboGAMIjectors® will pay for themselves in fuel savings alone. For more information visit the GAMI web site or read our Suggestions for Operation of the Turbonormalized IO-520/IO-550 article.
  $199
  

For aircraft being upgraded to the new "Whirlwind System III" package as described above, we will supply a new nameplate for the upper cowl door designating it as a "System III" conversion. This will provide continuing evidence and value as the premier turbonormalizing installation available on Bonanzas today.

IO-520 to IO-550 Engine Upgrade

Tornado Alley Turbo, Inc. is pleased to announce the recently received STC modification that now allows for the upgrading of the engine size from an IO-520 to and IO-550 when done along with the installation of the turbonormalizing system. The increase in horsepower from 285 to 300 (minimum) provides for shorter takeoff roll, increased rate of climb ~(150 fpm) and increased cruise airspeed ~(5-7 kts). With the excellent cooling provided by the "Liquidair" Baffle Kit, well controlled engine temperatures are possible even under high power operation. This IO-550 installation combined with the Whirlwind System III turbonormalizing system is the definitive, ultimate power package for your Bonanza.

JPI Engine Monitor

J. P. Instruments digital engine monitor is the definitive, easy to read, most accurate engine monitor on the market. This instrument is required equipment on the Whirlwind installations. With single digit resolution of all CHTs, EGTs, TITs, and graphic presentation as well, the JPI EDM 700 or 800 series, fine tuning of the fuel/air ratios can be accomplished. This allows for smooth, cool, safe, efficient, operation on the lean side of peak TIT. Options include digital fuel flow, OAT, Oil, CDT, IAT, MP, RPM and HP. Installation takes approximately 16-20 hours. Once you fly behind one of these, you will recognize the benefits, comfort and safety provided by this information.
Instrument pricing is variable depending on selected options.

Electronic Wastegate Controller

Although still in the developmental stage, we are finalizing the design of a new breed of controller that will allow for significant performance increases in the turbonormalized system at takeoff and cruise.

"Whirlwind" Turbo Conversions for Barons

Ever dream of owning a turbonormalized Baron? With the proven performance benefits of the "Whirlwind" turbonormalizing systems, having two is twice the fun! Baron Models C, D, E and 58 are first on the development list. If you or a friend are interested in this modification, please contact Tornado Alley Turbo, Inc. We are deep in the design process and are interested in comments and interest from owners.
