tvs vs twin screw

This means it took 147 hp to drive the TVS supercharger at this speed and flow level. As with the twin-screw design, the TVS supercharger was developed to expand the efficiency range of the supercharger to deliver more power at lower RPM and sustained boost at higher RPM, while requiring less engine power to drive. Lv 6. Lysholm Twin-screw (a.k.a. Lysholm Twin-screw (a.k.a. Just think, you could be stuck with just 664 hp running the same pulley configuration or making as much as 774 wheel hp (800 with H-series blower). Five generations later, the TVS® (Twin Vortices Series®) was a revolutionary design that provides an incredible 12% efficiency improvement. By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60-degrees. Taking these same readings between the throttle body and mass air or between the mass air and filter will help you know exactly where the restriction is most prominent. But Its not likely relevant for the street. The rotors on this system literally look like screws. Why? By running the same 2.59-inch blower pulley on the TVS blower, the peak boost numbers jumped from 11.5 to 14.5 psi. Its impressive performance is largely due to the unit’s state of the art rotor assembly. A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine.This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing the power output.. Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine's crankshaft. Naturally, backup runs were recorded to verify the power numbers generated by each pulley size. Replacing the mass air housing and filter (Stage 2 upgrade) dropped the vacuum present in the inlet tract from 5.3 inches down to 3.3 inches and increased the peak power to 727 hp. Since the stock blower will already deliver 550 rwhp with bolt-ons and tuning (up from roughly 440 rwhp in stock trim), the TVS looks pretty enticing, and it’s no wonder Shelby Automobiles chose to offer the TVS as on of the blower upgrades for its Super Snake program. Jump to Latest Follow 21 - 27 of 27 Posts. Were maximum power the design goal, you’d quickly see a change to the Twin Screw design. Stepping up to the Stage 3 induction system replaced the stock throttle body (with a dual 75mm unit) and intake tube (between the throttle body and mass air). In today’s video, we strap our 2012 Mustang GT500 to the dyno and put our VMP Gen3R head to head with a competitor’s 2.8 L twin-screw supercharger. Equipped with the factory M122, 2.59-inch blower pulley and optimized tune (11.5 A/F and 23 degrees timing), the 5.4 produced 518 hp (up from 443 hp in stock configuration). The answer is easy: anyone who pulls up next to a car sporting 790 rwhp! From a reader’s standpoint, I’m sure you were mostly concerned with how much power each system made, but there was–and still is–much more to the equation than sheer power number. On the blower dyno, the superchargers are mounted to a test fixture and spun using (in this case) a 400hp V-8 LS-series GM engine. Nowhere was this more evident than the use of the Twin Screw on the (cost-is-no-object and higher horsepower) Ford GT. The rotors on this system literally look like screws. The corrected result is even more surprising (to me) than my initial analysis: The TVS is far more efficient vs. this particular twin-screw than I initially thought, as you stated above. The Eaton, on the other hand, simply moves air from one side of the blower to the other. In anticipation of the high-boost runs, the fuel tank was filled with 100-octane race unleaded fuel to eliminate any possibility of detonation. 6,{{{300}}} 416.90 500.10 471.59 565.70 54.69 65.60 658.91 790.40 187.32 224.70, Mustang 2V, 3V, & Cobra Mammoth Dual 75MM-1880 CFM, Bigun Inlet Manifold & Throttle Body 3800 CFM, External Spring Supercharger Bypass Valve. Starting out where the TVS Roots blower left off, the 2.8-liter H-series blower from Kenne Bell is capable of supporting more than 1,000 flywheel horsepower and has already demonstrated that it’s capable of producing 800 rwhp on an otherwise stock GT500 engine.
