For 2005-09 cars, the kit also includes an open-element cold-air induction system and a 113mm intake tube (with mass airflow sensor provision). Certainly it would be interesting to compare the Roots and the Twin Screw in the exact same displacement and with equivalent aero-restriction inlet systems to see the similarity of the numbers, but for now, Kenne Bell’s test provides an interesting look at two of the popular upgrade options for GT500 owners as available. [MORE] Are Front Entry Superchargers Really Better? Unlike the traditional Roots, the Twin Screw is (to a minor extent) a true compressor, meaning that internal compression takes place inside the blower. The last blower upgrade featured the Kenne Bell 2.8-liter H-series blower. For a mainly street-driven car within the positive-displacement family, we like either a twin-screw or an Eaton TVS supercharger. The cars were driven on the same track, by the same driver, on the same day. By contrast, a twin-screw blower can never truly be unloaded even with a bypass, because if it is spinning, it is compressing air whether it is needed or not. Contents. The SLP 1900 TVS supercharger is a positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. May 11, 2019 May 11, 2019 Constance Fisher Constance Fisher 0 Comments. 2. The Eaton, on the other hand, simply moves air from one side of the blower to the other. 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). This means it took 147 hp to drive the TVS supercharger at this speed and flow level. Every component in the induction system must be up to the task of supporting the desired power level. Stage 2 727 3.3 2.8 Mammoth Stock Stock Kenne Bell Kenne Bell When boost is not called for they have virtually no parasitic losses and big advantage for OEM use. Plus, it's the same bolt on assembly that Ford uses. For a mainly street-driven car within the positive-displacement family, we like either a twin-screw or an Eaton TVS supercharger. It's what makes it yours. Today, the preferred choice is the Twin Screw. Available for most modern late model Ford, Chevy and Dodge applications. In stock configuration, the M122 blower provided a peak of 8.7 pounds of boost, but for our needs, we wanted to find out what was possible by running the smallest blower pulley possible. Relevance. Running the TVS blower in the same state of tune and with the same pulley size, the peak power numbers jumped to 614 hp. The 8 Bays of the Thunderbolt TVS-872XT each have their own dedicated LED indicator, as well as their own locking mechanism to ensure drives are not accidentally removed whilst in use, an annoyingly common way that people screw up there RAID array – you would be amazed! This meant the installation of a 2.59-inch blower pulley (using a smaller pulley requires machining of the b. 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. Kenne Bell even offers a larger mass air housing and filter assembly. More Photo Galleries. Stage 3 745 0 2.8 Mammoth Kenne Bell Kenne Bell Kenne Bell Kenne Bell It should be said that additional power is available from the stock M122 blower with a larger crank pulley and modifications to the intake tract (air filter and inlet tubing, mass air housing, and throttle body), but ultimately, it’s the blower itself that limits power production. Because twin-screw melt granulation is carried out at higher temperatures than traditional batch melt granulation, thermoplastic polymers can be used as binders. Powered by a belt driven from the engine crankshaft. It has been well documented in numerous tests by automotive engineers around the world that the Twin Screw concept is, unquestionably, more efficient (cooler air charge temperature and lower parasitic loss). On The Dyno By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60-degrees. 4,500 504.30 432.10 587.17 503.10 82.87 71.00 725.24 621.40 138.07 118.30 6.4 Hemi Supercharger Kits Are you in the market for a 6.4L HEMI supercharger? LCD TVs. 7 1. There are good reasons why OEM manufacturers rely on Twin Vortices Series (TVS) technology for factory supercharger applications: higher performance with ultimate reliability. A twin-screw supercharger operates by pulling air through a pair of meshing lobes that resemble a set of worm gears. The ROUSH R2300 TVS supercharger is a roots-type positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. All of these things must be accounted for in order to produce reliable results. Back to Article. By comparison, the Kenne Bell required only 12,700 rpm to produce the same 20 psi. Thanks! In anticipation of the high-boost runs, the fuel tank was filled with 100-octane race unleaded fuel to eliminate any possibility of detonation. Chevy does on theirs. Roots and twin screw are both fixed displacement superchargers. Download Image. Save up to $1,000 with Re-Tune. YouTube. Equipped with the same blower pulley, the TVS supercharger increased the peak boost pressure from 11.5 psi with the M122 to 14.5 psi. Before getting to the results, it’s worth recounting a bit of forced-induction theory. And when compared with previous three-rotor designs, the TVS represents a night-and-day difference in overall performance. Knowing the intensity of GT500 owners (even more so, the Super Snake customers), every effort was made to ensure accurate, repeatable data. As expected of a positive-displacement supercharger, the torque curves were pretty flat. TVS vs. Twin-screw. Another advantage of roots types is that both rotors spin at the same rpm because both rotors have the same number of lobes -- typically 3, except TVS has 4 high … Understanding how many owners of both solutions (TVS and Twin Screw) made the switch in the other direction should be solid information that can be considered valuable when making a supercharger purchasing decision. The combination of the performance tune and swapping on the 2.59 blower pulley brought the peak power output from 443 to 518 hp. These numbers are the rated flywheel power outputs just as the stock GT500 is rated by Ford at 500 flywheel horsepower. Answer Save. Not everyone can or will crank up the boost to the maximum setting and then make the concerted (and important) effort to minimize inlet restrictions. 2,000 442.48 168.50 473.73 180.40 31.25 11. With an increase in both displacement (2.3 versus 2.1 liters) and efficiency (see previous description of changes to TVS), it’s not surprising that the TVS blower increased the power output of the GT500 motor. Posted by on July 14, 2020. By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60-degrees. Historically as we all know the twin screw comes strong in the upper RPM range, I'm hoping it narrows the margin in the lower. If this Gen-3 Whipple carries the same or similar low end torque as the TVS 2.3 or the new 2650 and yet maintain lower IAT's and compete with the new 2650 in the upper RPM range it will give us all more options. With the testing completed on the M122, it was time for the Super Snake to receive the TVS blower upgrade. include; Turbo mustang drag car gear; Supercharger Tech The Kenne Bell 30HP Advantage $600 "Real" Cool Air Kit is standard on Kenne Bell Kits. 2 Answers. Like the Roots supercharger, the air inside a twin-screw supercharger is trapped in pockets created by the rotor lobes. The rotors on this system literally look like screws. In fact, both blowers in this comparison are offered by Shelby as upgrades to the original M112 used on the GT500–the new 2.3-liter TVS Roots blower from Eaton and 2.8-liter H-series Twin Screw from Kenne Bell–and as power options on the Super Snake versions. Stage 3+ 801 0 2.8H Mammoth Kenne Bell Kenne Bell Kenne Bell Kenne Bell. Although from the out side, screw type superchargers may look a lot like Roots type superchargers, on the inside you will find a twin-screw design that compresses air unlike Roots type superchargers which pump the air into the motor. It should also be noted that the 5.4 was equipped with a standard 17V Boost-a-Pump, stock 52-lb/hr injectors, and a custom tune to maximize power production with an air/fuel ratio of 11.5:1 and 23 degrees of total timing (values used for all of the tests to ensure repeatability). Screw) superchargers work by pushing air through a pair of interlocking rotors as the assembly rotates. Not so many moons ago, I was responsible for one of many supercharger comparison tests (in another magazine), putting an Eaton Roots supercharger against its positive-displacement cousin, the Twin Screw, and here I am again. Some TVs may be better for sport watchers, and other TVs may suit those who prefer movie or series. Lysholm Twin-screw (a.k.a. Lv 6. The front drive / front inlet design allows for a shorter less restrictive intake path allowing for improved air flow and superior performance. Basically, Eatons take on TVS vs. twin screw. “In turn, what you can typically do with timing and air/fuel ratio on a twin screw style of supercharger, is less as the RPM and timing increases on a roots style. Thus the Twin Screw reduced the inlet charge temp, blower speed, and parasitic losses required to reach the desired boost level. “The symmetrical rotor design of TVS technology allows for a much higher RPM ceiling. Share this photo. Popping The Cork Case in point, that positive-displacement supercharger slugfest pitted the like-displacement 3150 Twin Screw Autorotor versus the standard Roots-style M90 Eaton. 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). Roots Supercharger. I really think TRD hit it out of the park with this kit. REV 300 supercharger kit based on a Eaton Harrop TVS1320 twin vortices compressor, a water to air chargecooler can be sandwiched in, fits Elise body. While it doesn’t compare to the 500 hp required to drive a Top Fuel Roots blower, some of these larger street/strip superchargers required as much as 150 hp to spin them at 18,000 rpm and 20-plus pounds of boost. Who (you might ask) really needs 800 rwhp? Replacing the standard 2.8 blower with the 2.8 H-series took the 5.4 to 800 rwhp (using the same 2.5-inch blower pulley and Stage 3 induction). Unless the KB differs significantly from the Lysholm, this suggests that the same size TVS will outperform the KB all day. The more things change, the more they stay the same. The final test was to remove the TVS and install the Kenne Bell Twin Screw supercharger. Why? If any vacuum is present when running at or near the peak engine speed at wide-open throttle, there’s a restriction in the inlet system somewhere. Back in the days of Kenne Bell twin-screw 2.8 vs Magnuson 2.3 TVS, the real difference was that the TVS was better efficient to 16psi, and then the larger size of the Twin-Screw helped outflow at anything above that. {{{80}}} 92.96 35.40 That the Kenne Bell Twin Screw is capable of producing 800 rwhp by simply cranking up the boost on a GT500 motor is truly impressive, and we’ll likely see many Super Snake enthusiasts running the requisite race fuel and small blower pulley (2.5 inches) required to reach the 800hp mark. UPDATE: If you swapped a stock blower to a TVS, please don't take the poll. Screw type superchargers are derived from the Roots type concept but with vast improvements for street use. Replacing the throttle body, inlet air tube, mass-air housing, and filter assembly improved the power output of the supercharged 5.4 from 664 hp to 745 hp. The Eaton TVS Supercharger has been improving engine performance since 1985, beginning with the reknown M-Series. Back to Article.
