Making the first full billet 7 axis custom turbo compressor cover from solid aluminum. In centrifugal compressor design, the volute plays a key role in defining the overall efficiency and operating range of the stage.

The flow at the impeller outlet is indeed characterized by a high kinetic energy content, which is first converted to potential energy in the diffuser downstream. The compressed gas is then collected by the volute at the cylindrical outlet section of the diffuser and directed to the intake piping, possibly with a further pressure recovery to enhance the stage performance. Due to the high flow speed at the volute inlet, the capability of ensuring the lowest amount of total pressure loss is pivotal to prevent a detriment of the machine efficiency. Moreover, the flow conditions change when the volute operates far from its design point: at mass flow rates lower than the design one, the flow becomes diffusive, while at higher mass flow rates the fluid is accelerated, thus leading to different loss-generation mechanisms. These phenomena are particularly relevant in turbocharger applications, where the compressor needs to cover a wide functioning range, moreover, in these applications, the definition of the volute shape is often driven also by space limitations imposed by the vehicle layout, leading to a variety of volute types. The present paper reports an analysis on the sources of thermodynamic irreversibility occurring inside different volutes applied to a centrifugal compressor for turbocharging applications. With this new design achieves better flow characteristics and lower volute temperatures. Also, can be adjusted on every compressor wheel size and characteristics. Import Tennalum alloy in motorsport, provides the highest mechanical strength of all aluminum alloys and matching that of certain steels. This outstanding alloy combines a yield strength of up to 700 MPa (up to over 30% greater than that of 7075 alloy) and good ductility with corrosion resistance similar to 7075 and other features beneficial to high performance component/equipment designers. In strength-to-weight ratio is the best material ever produced, Tennalum® out performs nearly all other engineering alloys in existence (33% better strength-to-weight performance than 7075, and 28% better performance than 6Al-4V Grade 5 Titanium). For many applications there is no better alloy, not even Titanium. 40% lighter than titanium. Made for aviation, aerospace & defense. He made Rods / pistons /Compressor wheels and more items for motorsports. "Gen2 patent" 10 blades single raw, design compressor wheel technology, using “super alloy 970mpa” material. 43% lower weight than titanium Ti6AL4v and 35% stronger. A next generation of compressor wheel for a turbocharger revolutionary improved aerodynamically, improved geometry that provides 35-80% more performance as compared with a comparably sized conventional compressor wheel by having the radially inward portion of the primary blades sweep upwardly into the upper region of the hub portion. The through bore and integral nut of compressor wheels is eliminated and replaced with a blade extension that has an angled upper edge which extends downwardly and radially outwardly from the hub portion, that’s the Curve towards the root design, and second base design is the two-way curve in the blade from top view. One way starting from hub with one rotation and at the opposite (end) of the same blade the second curve rotation is different direction. These 2 points (Curve towards the root-hub) and Curve of blade two way effectively increasing the size of the blade, the amount of air movement and the amount of power generated, without increase the size and mases’ weight of the compressor wheel. The compressor wheel blades are in one line fitted to hub and not as the normal old style compressor wheels fitted in two rows (primary and secondary), the benefit of this is that the moving masses of air in the same rotation speed of the compression wheel can be 43%-68% more than any other two row old design.
