This ethos has defined the direction of the KRATOS brand.\u003c\/p\u003e\n\u003cp\u003eKRATOS came into conception through a group of engineers with 25+ years of private label design and manufacturing turbo systems for various house-hold name performance brands. These engineers saw a untouched segment in the high end European market for True OEM Style Dual Ceramic Ball Bearing Turbo System Manufacturing and through that revelation the KRATOS brand was born.\u003c\/p\u003e\n\u003cp\u003eKRATOS systems are forged from the finest raw materials and assembled with strenuous attention to detail. Every component is purposefully designed and engineered-in-house and tested to extreme standards. KRATOS is The Only True Dual Ceramic Ball Bearing OEM Fit CORE-LESS Turbo System Manufacturer.\u003c\/p\u003e\n\u003cp\u003eKRATOS aims to provide exclusive turbo systems for premium European performance vehicles. This goal is achieved through pride and purity of engineering as well as uncompromised use of top tier materials and manufacturing methods.\u003c\/p\u003e\n\u003cp\u003eKRATOS was recently acquired by Global Motoring Group LLC, not to be confused with racing company GMG. This has further emphasized the focus of the KRATOS brand is to provide OE fit turbo solutions to top tier European performance cars.\u003c\/p\u003e\n\u003cp\u003ePower and Results:\u003c\/p\u003e\n\u003cp\u003eTesting:\u003c\/p\u003e\n\u003cp\u003eProduct prototypes have been in testing through 20k+ miles of daily driving at 750whp+ on beta test vehicles. In addition, KRATOS was approached by Strom Motorsports road racing team due to the inefficiencies and failures of the factory turbos they had experienced. Strom Motorsports recently took first place in the GT4 class at the Bathurst 12HR. Durability and endurance testing has primarily been completed Strom’s 25HR endurance M4 race car as well as their time attack M4.\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/f9zznbs.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003ePower:\u003c\/p\u003e\n\u003cp\u003eList of modifications\u003cbr\u003eStock Engine\u003cbr\u003eStock Intercooler\u003cbr\u003eDownpipes\u003cbr\u003eIntakes\u003cbr\u003eSpec Stage 2+ Clutch\u003cbr\u003eFuel-It PI\u003cbr\u003eMaximum PSI Crank Hub\u003cbr\u003eBootMod3\u003cbr\u003eHCP Custom Tune\u003cbr\u003eKRAS55Bi Turbo System (Standard Billet Wheel Option)\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/hhshwb9.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eThis Dyno Graph depicts the capability of the KRAS55Bi on a stock BMW S55 engine with the supporting modifications listed above at 32psi on E85 fuel. Notice how power continues to climb to the rev limiter which is a results of the compressor wheel, turbine wheel, and manifold A\/R ratio design. The goal was to achieve 800whp on a stock engine safely while limiting midrange torque and horsepower for the safety of the connecting rods. More boost or timing was not applied to the stock engine for higher horsepower figures as durability and reliability are one of the main focuses of the KRATOS brand. It’s imperative that the test vehicles go through the proper sequence of durability testing at each tested power level before increases in power are applied. As KRATOS has been working very closely with BM3 and HCP tuning, with a built engine and cylinder head the KRAS55Bi will be capable of supporting up to 900whp with the proper tuning.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/qhafxpa.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eThis Dyno Graph depicts the capability of the KRAS55Bi on a stock BMW S55 engine with supporting modifications listed above on 93 octane fuel only. As 93 octane is a much hotter burning fuel, along with that comes higher egt’s at given boost levels as well as a lower detonation ceiling. With that in mind, HCP Tuning devised a custom tune as boost and timing are tapered in the upper rpm to increase reliability and repeatability of power.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/13kr7k2.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eThis Dyno Graph depicts the differences in power between the same BMW S55 engine on stock OEM turbos E30 Fuel Only with all modifications listed above without Fuel-It PI vs. KRAS55Bi on E85. There are other S55 that have made more power with stock turbos and stock fuel system, however this is the power that was made on the same vehicle which is why this data was used. Notice at 6900rpm there is a Difference of 327whp between the stock turbos and the KRAS55Bi. These figures are used for reference only, but they do give the end user an idea as to the difference of power that can be achieved when upgrading from a stock OEM turbo system on E30 to a KRAS55Bi on E85.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/clvrsc4.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eThis Dyno Graph depicts the differences in power between the same BMW S55 engine on stock OEM turbos 93 octane fuel only with all modifications listed above without Fuel-It PI vs. KRAS55Bi on 93 octane fuel only.

The introduction of the KRAS55Bi proves that early connecting rod failure on stock engines is more a result of high exhaust back pressure along with extreme torque demands rather than a pre-mature mechanical limit of the rotating assembly based on data from several high mileage 750+whp beta test vehicles. The shape of the dyno curves listed above are a visual representation of the KRATOS Engineering Team’s success at disproving this fact.\u003c\/p\u003e\n\u003cp\u003eTechnical Summary:\u003c\/p\u003e\n\u003cp\u003eCeramic Ball Bearing Cartridge (Patent Pending):\u003c\/p\u003e\n\u003cp\u003eKRATOS ceramic ball bearing technology encompasses industry leading technology in an OE fitment package.

The turbofold reduces backpressure significantly, making engine operation at higher output safer and more reliable. In testing, data proved a 1.1:1 Backpressure rating at 32psi. A car making 32psi of boost would see 35.2psi of pressure on the manifold side. This allows for the engine to cycle without additional stress of vacating spent exhaust through a manifold with high resistance. If not addressed, excessive back pressure causes undue stress resulting connecting rod failures as well as loss of power and engine efficiency.\u003c\/p\u003e\n\u003cp\u003eMathematically matched A\/R ratio.\u003cbr\u003eReduced heat and increased turbine efficiency.\u003cbr\u003eSmoother internal runner transitions.\u003cbr\u003eIncreased runner diameter.\u003cbr\u003eComputational Fluid Dynamics modeling software tested.\u003cbr\u003e316 Stainless Steel.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/bzbjqqp.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-gd6olw6\/product_images\/uploaded_images\/z1lmmux.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eOEM Fitment and Core-Less Design:\u003c\/p\u003e\n\u003cp\u003eThe integration of ceramic ball bearing technology into true OEM fitment is unique to the KRATOS brand. Like all other KRATOS line of products to follow, the KRAS55 series retains use of factory oil and water lines without use of adapters of any sort.
