The KRATOS KRAS55Bi-EVO
kratos bmw m3 / m4 / m2 competition s55 turbo upgrade. The cornerstone of our S55 system is the one-piece turbo-fold. Combining both the manifolds and turbine housings, crafting the turbo-fold as one piece within the confines of stainless steel investment casting was a feat of engineering prowess.
Mathematically matched A/R ratio
Reduced heat and increased turbine efficiency
Smoother internal transitions due to redesigned runners
Computational Fluid Dynamics modeling software tested
316 Stainless Steel
Ceramic Ball Bearing Technology
A distinctive feature of any KRATOS Turbo system is proprietary silicon nitride ceramic ball bearing technology. It offers efficiency and reliability unmatched by any other technology.
5x the service life of steel ball bearings
Significantly lower temperatures than steel ball bearings – up to 50% higher operating speed
Increased efficiency and thrust load capability
Near frictionless operation requiring minimal oiling
Heightened transient response
KRATOS ceramic ball bearing cartridges have been engineered to withstand extreme forms of abuse. KRATOS bearing housings have been endurance race tested and have proven themselves to be reliable in the most extreme conditions. Designed to be fully rebuild able, KRATOS turbo systems are without equal in the industry.
The striking compressor wheels are one of the cornerstones of a KRATOS Turbo system. Sculpted out of a solid block of forged billet aluminum, their strength grants the ability to utilize more radical point milled third-order geometry designs. With extensive and masterful use of various compressor wheel design traits, the KRATOS wheels are in a class of their own
Stainless Steel Investment Casting
Stainless steel investment casting is the perfect combination of form and function; robustly beautiful. Stainless steel investment casting is part of the identity of the KRATOS brand and is one of the most noticeable superficial features.
Extensive design considerations were taken to achieve the use of stainless steel investment casting in an all-encompassing OEM fitment turbo system. The 316 stainless steel used to produce KRATOS castings in addition to higher nickel content, 316 also contains two percent molybdenum which is attributed to its extreme corrosion resistance over that of 304 stainless steel.
Potency and resilience, the Ti6Al4V titanium compressor wheel option offers extended performance from the already radical billet variant. The sheer strength of this space-age material grants more aggressive design capabilities. KRAS55Ti features a unique third-order geometry, point milled eight blade compressor wheel designed specifically for use on the S55. With supporting modifications, this wheel is capable of 1000+ whp, achieving this with calculated precision, not brutish excess.
Application Specific Engineering
Certain applications require additional components in order to complete the turbo system. In the case of the BMW S55, turbo inlets needed to be provided to match the increased compressor diameter. The four-ply silicon inlets for the S55 also feature a match ported polished billet elbow. These inlets are direct fit to OEM crank case ventilation and intakes by utilizing our OEM fit billet flanges. KRATOS Turbo Systems represent a fully developed solution for each application.
