The turbocharger industry is an industry under tremendous pressure to evolve. As consumers demand more power and performance out of their engines, it is coming via more air. This increased air flow can come from many different upgrades. Adding higher flowing heads, longer duration cams, bigger turbochargers, more boost, well you get the idea.

Bullseye Power was an early adopter of triples. Their company truck features three BatMoWheel’ed S300’s.

In the diesel market, higher flowing heads aren’t necessarily readily available to most people. There are a couple of companies offering heads but they aren’t the most affordable option. Camshafts are constantly swapped on Cummins engines but the Duramax and Power Stroke engines require substantial tear down to upgrade. So, most only upgrade their cams when the building/rebuilding their engines.

So, we are left with larger turbochargers and more boost pressure. Unfortunately, upgrading to a larger turbocharger isnt’ always the best idea. A larger charger has more mass and usually takes more energy to rotate. So, they don’t respond as quickly as a smaller charger would. In addition, depending on what you are doing, some classes in competition regulate the size of turbocharger you can have.

More boost then?

All things being equal, more boost does mean more power. That being said, how the boost is being made is the real story here. A turbocharger makes boost with a compressor wheel. The wheel is designed to take large volumes of low pressure air in, compress it, and force it through the system. Each of these three stages represents potential areas to focus on for improvement.

The compressor on the left is a BatMoWheel and the right is a billet wheel. Notice the difference in the rake of the blades as well as the shape.

A few years ago, Bullseye Power decided to focus on how the air is compressed. They started with their many years of experience and a few designs that they knew worked. Over the next few months, they blended many ideas together and came up with an odd shaped wheel. This new wheel has a rather unique curve to the top edge of the wheel. In addition to the unique top curvature, they also, focused on the pitch, rake, number of blades and really all aspects of the wheel to maximize performance.

But how can a small company’s products outperform a large companies products?

This is what Bullseye Power calls a double BatMoWheel. Notice both blades are curved.

It is simple, a small company is willing to invest and focus on niches that a larger company may not see or with their overhead, not able to produce something for. Bullseye Power was originally focused on the competition market. They were working with specific sled pullers and drag racers trying to maximize their power. During their research, they came across something rather spectacular. Their new BatMoWheel was actually showing improvements across the entire rpm range not just the top end.

Since the original design, they have continued to refine their wheel to create what they offer today. The BatMoWheels have been optimized to increase performance throughout the entire rpm range. They are offered in a wide range of sizes (52 through 94mm) and have gone through 100,000 miles of stress testing.

When you are ready to upgrade your turbocharger or are looking for more power, give the guys at Bullseye Power a call. They may be able to blow you away with their offerings.
