Pricing for LS3 Bull Moose 480 hp Firewall Forward Package
WATCH FOR AN ANNOUNCEMENT OF THE NEW 525 HP VERSION. This is becoming the engine of choice for our float customers. Stay tuned!
The Heart of the "Super Moose"*..
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 dyno chart shows the "sweet spot" of this engine to be at 5,200 rpm procuding 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.
NOTE: The use of this engine package requires the use of our "Super Moose" airframe upgrade package.
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.
*ATTENTION: The "Bull Moose and Super Moose" designations and assemblies are proprietary model names and packages developed by MooseMods who hold the exclusive right for the use of those named identifiers..

THIS IS NOT YOUR GRANDFATHER'S AUTO CONVERSION!
LS 3 480 hp MooseMods "Plug and Play" package: $48,500 US. This as ordered package is ready to bolt to your airframe; add fuel, engine oil, PSRU gear oil and ready for start up. Allow 90 days lead time.
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.
Engine Install Pictures
The SUPER MOOSE package includes the 380 or 430 horsepower version of the same LS3 engine used in the BULL MOOSE. All of the same proven components are used in this package. The 380 hp version is an excellent choice for an owner wanting greatly improved performance and operational economy beyond the currently available standard aircraft engines for either the standard SR 2500 or SR 3500 airframes. Let's talk about your aircraft mission needs and see if this package would serve you well..
LS3 Aircraft Engine
As designed and developed exclusively for the Murphy Moose and Super Rebel aircraft by MooseMods and LSaeroengines.
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 will provide either all of the components for an owner install, assemble a ready to bolt on engine package, or do a complete install of the desired package with your airframe at our facility.
Includes GM Factory New Engine, PSRU with bell housing and coupling system, SDS Engine Management system, engine mounts, complete cooling system, all accessories and MooseMods proprietary upgrades.
The airframe of the Murphy Moose and Super Rebel aircraft have a well deserved reputation of having a robust structure. After extensive field operations it has been demonstrated that some structural enhancements would add to that utilitarian design, so we have taken the thoughts and ideas many have contributed and put them into production and are making them available to builders and owners of operating aircraft. Most of these are such that they can be retrofitted to existing aircraft. Of course it is much easier to incorporate those into the original build process, so we encourage that and are glad to support builders in the integration of these elements which do not compromise the original design, but rather enhance the strength and utility of the airframe.
