Life is an ongoing maze of decisions. Some are fortunate enough to make all the right turns, open the proper doors, and duck at the appropriate times. Others, well let's say if some got paid for bad luck, they would be millionaires by now. Having to make relevant decisions usually starts before final dismissal from high school.

Fortunately for the four young men who started Mast Motorsports, they have efficiently worked through the maze at this point, three of them graduating from Texas A&M University with Bachelors degrees in Mechanical Engineering, and all coming together to carry out a mission. This mission includes bringing top-notch ingenuity and reliability to the already crowded aftermarket. After all, this love for the automobile did not start with a calculator in hand; it started with a young man and a vision.

While still in high school, Horace Mast took a liking to the automotive engine and spent numerous hours working on his diesel truck. After almost tripling the horsepower output of the engine, it was a no-brainer that this was his passion and destiny.

While still in college, Horace was part of a program that pooled mechanical engineering students from around the world to compete in the design and construction of smaller scaled open wheel racecars.

Mast Motorsports Crate Engines Engine Dynometer
Mast's state of the art engine dynamometer: the Superflow NSCR/SF-902-model, which promotes consistent readings through a controlled oil and coolant exchange system. This system keeps temperature levels within 3 Fahrenheit from test to test. Also within the unit are built-in tests that ensure consistent testing-not much room for human error. Oh yeah, that's the L92 HO V2 going through the motions once again.

During the Formula Society of Automotive Engineers competition, engineering students from their respective schools build the car from the ground up-designing, manufacturing, and testing each component. Not only does this teach by letting student get their hands dirty, but it also allows the students to network with the American automakers (Chrysler, GM, and Ford).

In order to shed weight from the car, Horace designed a single-cylinder supercharged engine. This particular unit produced the same power output of the previous four-cylinder unit, with the added benefit of shedding 75 pounds in the process (lighter is faster). The A&M car competed in two international FSAE competitions in 2006, winning first place in the FSAE West competition at California International Speedway over a field of 75 cars.

After deciding not to pursue a career with one of the Big Three automakers, Horace got together with a few close friends and fellow graduates, and they decided to put their knowledge to use and begin Mast Motorsports.

Mast Motorsports began its life out of a small office, with engines on stands next to desks and computers. Horace began selecting hardware components for a proprietary aftermarket tunable ECM. This would not be your standard stand-alone unit, but a versatile unit used to control many high-end functions such as DBW technology (Drive By Wire).

Beyond the construction of this ECM, Horace was intrigued by the technology being used called VVT (Variable Valve Timing). Mast figured he could gain massive amounts of power through technology rather than swapping out a boatload of aftermarket parts. While the addition of aftermarket parts will aid in gaining gobs of power, it may hurt drivability, fuel consumption, emissions, and, most of all, your pocket. Mast is trying to keep these issues to a minimum, while providing long lasting reliability and a thrill behind the wheel.

Mast Motorsports spends hours on top of hours performing tests on its engine dyno, ensuring that all bases are covered. Mast has developed its M-90 ECM, along with multiple wiring harnesses (which meet or exceed OEM quality). Mast will first enter the aftermarket with its turnkey crate engines, complete from soup to nuts. All crate engines will leave the facility pre-tested and fully tuned for your specific application. Whether it's a full-bodied killer or a sand rail, Mast has you covered.

  • Mast Motorsports Crate Engines Serpentine Belt System
    Mast Motorsports is also in the early stages of developing a complete serpentine belt system for the LS series engine family. Most pulleys pictured are unfinished, one-off pieces. Look at the beefy brackets.

  • Mast Motorsports Crate Engines ECM
    Here we have the M-90 ECM currently being used on the dyno. Notice its compact, rugged design. Also contained within the unit are rubber mountings to aid in shock absorption. In case you're wondering, the "M" stands for Mast and the "90" for its 90-pin connection. The M-90 has many capabilities including: Drive by Wire, Variable Valve Timing, Wideband Knock control, Wide Band O2 capabilities, Octane Learn for changes in fuel conditions, and corrected fuel pressure tables. The M-90 can also be configured with or without ignition drivers depending on its given application. The M-90 also contains Throttle Position Governing. This feature allows for two-step activation with a smooth rev limit applied, which means no more banging and popping off the rev-limiter for the drag crowd.

  • Mast Motorsports Crate Engines Trans Am
    While in the rather large shop area we encountered a couple of odd items. One was the Pontiac Trans Am used for research and development. Since Chevy and Pontiac both use small-block Chevy power we deemed this acceptable. On the other hand we noticed a load of wooden crates, and after badgering Horace for an hour or so he indicated that there are 8-cylinders present in each one and that was it. I guess we'll find out later.

The majority of Mast's work has been on GM's L92, 6.2-liter engines. Mast likes these engines for their aggressive head design, VVT feature, and most of all, their affordability. The L92's main application from General Motors is in trucks and SUVs. Mast has outfitted these engines to fit both trucks and cars. The car version uses an L76 intake manifold, while the truck version employs the truck intake (TI). By merely adding the Mast Motorsports V2 camshaft, Comp valve springs (#918), and M-90 ECM with Mast's tune, horsepower numbers have been proven in the 540 range with 490 lb-ft of torque. Not bad compared to an LS7 7.0-liter crate engine, which checks in at 505 hp and 470 lb-ft of torque from the factory. The complete L92 HO V2 turnkey package costs around $11,199, significantly less than the LS7 crate engine containing no electronics.

  • Mast Motorsports Crate Engines Fuel Pressure Kit
    Here are the remote-mount and rail-mount fuel pressure correction kits. They monitor fuel pressure over all operating conditions. The M-90 ECM can then correct fuel-flow calculations in order to adjust for changes in fuel pressure during operation or changes in the base fuel pressure setting. At an MSRP of $149, how could you go wrong?

  • Mast Motorsports Crate Engines Chassis Dyno
    Here we obtained a sneak peak of Mast's Superflow chassis dyno. This particular model contains dual Eddy current, which enables the end user to simulate several different simulated driving conditions. The chassis dyno is used for in-house development only; it's closed to the general public.

  • Mast Motorsports Crate Engines Oxygen Sensor
    Shown here is a wideband heated oxygen sensor (top), and a traditional heated oxygen sensor found in most American passenger vehicles (bottom). The M-90 ECM is capable of working with both (but not at the same time). For you hot rodders, the M-90 can operate efficiently with a single O2 sensor, while the emissions-conscious catalytic converter crowd can run both pre- and post-catalytic sensors. The M-90 is a very versatile piece.

  • Mast Motorsports Crate Engines Throttle Body
    Next up we have the DBW throttle body, this happens to be a 90mm unit being used with the L92 HO V2 engine. While many are converting back to cable-operated units on their retro projects-stop! The DBW throttle body can easily be converted for use on the Gen-3 LS1/LS6 engines. Mast sells a complete conversion kit including the DBW throttle body, M-90 ECM, DBW foot pedal, and complete wiring harness for between $1,799 and $2,169 (depending on options and parts needed).

  • Mast Motorsports Crate Engines LSX Block Engine
    Yes, that is an LSX blocked engine on the dyno. The LSX454 is in very early developmental stages at this point but will become a reality soon. The engine was tested to be sure that the priority main oiling system would not have any effects on the VVT, which it has not. Although it is just speculation at this point, the folks at Mast are hoping to eclipse the 650-horse mark with this baby.Mast Motorsports has recently named Scoggin-Dickey Parts Center the exclusive dealer of its crate engines, although Mast Motorsports will be more than happy to answer any technical or product questions you may have.
