Tornado Alley Turbo's "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 STC s 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.
Pricing on the available upgrades is as follows:
1. 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. Kit price = $495 Installed Price = $595.
2. 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. Kit price = $995 Installed Price = $1295
3. “Rammer” Intercooler - Gain performance and efficiency with this larger intercooler that incorporates several significant changes in the induction sytem. The intercooler core area has been increased by 40%. The airflow into and through the intercooler has been streamlined for smoother transition and less back pressure. The induction tubing and couplings diameter downstream of the compressor has been increased and smoothed. The volume of cooling air through the intercooler has been effectively doubled. The landing light has been recessed to provide additional cooling air. All these changes serve to reduce the induction air temperature which has a number of beneficial effects such as improved takeoff performance, greater engine efficiency, cooler CHTs, and safer detonation margins. Retrofit installation including the recessed landing light is estimated at 12-14 hours. Kit Price = $ 4495, Installed Price = $4995.
4. 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. Kit Price = $ 1150, Installed Price = $1500.
5. 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 10-15º F. Must be sized to fit your aircraft. Available primed or painted 
to match. Primed Price = $800 per set of two, Painted Price = $1000 per set.
6. 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. Kit Price = $495 Installed primed price = $945 Installed painted price =$1195.
7. 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 www.gami.com web site or download and read the “Suggestions for Operation of the Turbonormalized IO-520/IO-550” on the www.taturbo.com web site. Price = $949.00 per set. Installed price = $1039.
For aircraft being upgraded to the new “Whirlwind System II” package as described above, we will supply a new nameplate for the upper cowl door designating it as a “ System II” 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 II” turbonormalizing system is the definitive, ultimate power package for your Bonanza. Call for pricing.
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 ranges from $1745- $3800 depending on options.
In the Future
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. Certification of this is just getting started but we hope to complete it soon.
GAMI's Supplenator™ - This 35 Amp Supplemental Alternator is driven off of the accessory drive pad on the back of the engine. With ample capacity to run virtually all primary equipment in the case of failure of the primary alternator, this Supplenator™ will come on line automatically to carry additional load or for use in an emergency. No clutches to exercise or fail when you need it most. The digital panel display monitors both alternators for volts and amps. With new circuitry for reliable voltage regulation, load management, and expansion for powering GAMI's PRISM™ Electronic Ignition, the Supplenator™ is truly state-of the-art. It's even self-exciting. That means that even if your battery shorts internally, the Supplenator™ will self start without the battery online to provide you power and safety. Certification is expected very soon. Be advised, there is already a waiting list for the Supplenator™ and a $500.00 discount for early orders. Call GAMI toll free @ 1-888-FLY- GAMI (1-888-359-4264) or refer to GAMI's web site www.GAMI.com for more information.
GAMI's PRISM™ Electronic Ignition - At last, technology that will not only update our ignition systems to the 21st Century, but will go beyond the multi-sensor automobile style FADEC systems of the OEMs. Using proprietary hardware and software developed by GAMI, the PRISM™ system continuously monitors and controls the cylinder combustion pressures for location relative to top dead center and for safeguarding the engine from detonation. This allows for the use of lower octane, unleaded fuels and improved performance at the same time. Certification is expected soon.
"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 starting the design process and are interested in comments and interest from owners.
