ADVENTURE AVIATION WEST, LLC

Moose Mods

During the often lengthy process of R&D and extensive hands on flight testing, we discovered that some of the external factory installed engine components were not up to the task of our reliability expectations. That being the case we have come up with high quality SFI approved replacements which have proven to meet the performance and reliability expectation we have for our engine packages. These are unique to our packages and not available elsewhere. We have also developed a proprietary tuning formula of the well proven SDS system to achieve the delicate balance of Air Fuel Ratios and how those impact the critical EGT management.  We will program the SDS systems we install to assure the best balance of those critical programs. We also provide for our customers specific data on critical fuel rail PSI.

With the wide range of options an owner has to consider, let's talk about what will best serve your needs and we will be glad to put together some firm numbers.  For starters, we assemble and ship a ready to bolt on "Plug and Play" engine package, or do a complete install of the desired package with your airframe at our facility.

The desire to develop a new generation, strong performing and reliable power plant led to the decision to use the GM LS 3 series engine for a range of aircraft applications.  The design of the 480/495 HP version used here in the Bull Moose was such that it was built for continuous high rpm by the use of a special camshaft and valve train for that application and a very flat torque curve.  Those elements and the readily available power plant made it an obvious choice.  It has proven to be a light, compact and high power to weight ratio engine which is demonstrating it's reliability in many applications.   The use of the Firewall Forward CAM 500 PSRU with the 2.11:1 reduction ratio, is proving to be an excellent package and one in which we are very comfortable in supplying to our customers.

Advantages of SDS vs. Conventional Aircraft Engine Systems

Virtually zero maintenance, lower fuel flows due to better mixture distribution, automatic mixture control, no carb heat, smoother running, no mag checks, no live mag issues, longer engine life due to proper mixture control and less bore washing are some of the major benefits of EFI.
Only MooseMods has developed proprietary programming of the SDS system from extensive in flight testing for efficient and safe operation of our LS3 packages.

Note:      The use of this engine package requires our ​Bull Moose airframe upgrades.  See

                information and pricing information below.

The  MONSTER MOOSE package includes the 525 horsepower version of the same LS3 engine used in the BULL MOOSE.  All of the same proven components are used in this package.  The 525 HP version is an excellent choice for an owner wanting greatly improved performance, particularly for float operations.

THIS IS NOT YOUR GRANDFATHER'S AUTO CONVERSION!

Firewall Forward CAM 500  PSRU provides a well proven system to accommodate the LS3 Engine.  Designed to be used for engines up to 750 hp, this unit is also capable of using two PTO adapters to drive both hydraulic prop governor and vacuum pump or other accessory.  This is a very robust and well produced unit with a great track record, hence the choice to use it in the Bull Moose and Super Moose packages. We are the designated US distributors for this unit, so please contact us directly.

NOTE:  The use of this engine package requires the use of our "​Bull Moose" airframe upgrade package.

The dyno chart shows the "sweet spot" of this engine to be at 5,200 rpm producing 480 hp and 480 ft-lbs. of torque, which is a perfect match to our 2.11:1 PSRU giving a take off RPM of approximately 2,500 for the propeller.  Engine cruise rpm of 4,000 produces 330hp, 450 ft-lbs of torque, and gives a prop rpm of just under 1,900, making for very strong and economical operation.
