Despite the same blower pulley size, the Kenne Bell offered 23 psi of boost and 736 lb-ft of torque. Either one has the capability to provide more power than your average driver is really equipped to handle, but for those who find too much is just right, now you’re better educated as to how these two options compare. I know a few people on here have talked "M112 upgrade" for the 99-04 cars but not wanting to blow the money … 1 decade ago. Look at it this way, they used a TVS on their 13-14 halo car. Volumetric efficiency and air flow properties are enhanced by the higher helix angle (the 5th generation has 60° of twist). Check out the short sidebar on inlet system testing, but know that any restriction in the inlet system (basically anything in front of the entry to the rotors themselves) will result in a drop to flow, boost production, and ultimately, power production. Comparison Between Roots, Twin Screw and Centrifugal Supercharger August 28, 2017 February 26, 2019 Pankaj Mishra 0 Comments Difference between , Supercharger Spread the love 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. That is not a poll option. Equipped with the M122 supercharger, torque production exceeded 500 lb-ft from 3,000 to 4,700 rpm, with a peak of 514 lb-ft. 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. Positive displacement pumps – such as the Roots, twin-screw (Lysholm), and TVS blowers. Favorite Answer. Available in some of the world's most powerful production cars and as an aftermarket upgrade, it is the perfect choice when you need to flow massive amounts of air. One of the problems associated with comparing any two performance components, let alone superchargers, is how to accurately test them. I … The increase in boost pressure has a positive effect on the torque curve, elevating the peak torque output to nearly 600 lb-ft. Torque production exceeded 500 lb-ft from 2,200 rpm all the way to 6,300 rpm (our redline). Roots types are simple pumps, moving air from above to below. Share this photo. Like the Roots supercharger, the air inside a twin-screw supercharger is trapped in pockets created by the rotor lobes. Some are cheap and some cost a bit more. Available for most modern late model Ford, Chevy and Dodge applications. 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. That’s why such a powerful drive motor is required. If you're looking to make big power in your high-performance vehicle, the TVS 2650 is what you need. Since it was already installed on the motor, the first series of tests was run with the stock Eaton M122. Why? Along with the 1.9L TVS blower, the basic VMP kit also includes a high-flow inlet elbow with the proper vacuum line and PCV line fittings. Chevy does on theirs. If you want to lose the warranty and add the Kenne Bell, that program will squeeze your wallet for $31,995. 5,000 497. The ZR1 is supposed to have 133HP more than the Z06 (638 vs 505), but I think this “rating” must be before things warm up. “The symmetrical rotor design of TVS technology allows for a much higher RPM ceiling. the Twin screw supercharger will rape both ct supercharger and kraft werk supercharger.at this moment the twin screw supercharger is given the highest WHP.bulliedog made 454 WHP with his Twinscrew supercharger.you could find the kit at MERC RACING and you could also ask bulliedog for advice on this kit. Although, they both put out a ton of instant boost and a lot of it. 2. These power gains came with no change in air/fuel, timing or blower pulley size. STOCK BLOWER TVS DIFFERENCE KENNE BELL DIFFERENCE 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. The more options we have the merrier. Running the stock ind-uction system from the blower manifold forward resulted in a peak power number of 664 hp. The Eaton Twin Vortices Series (TVS) is an Eaton product, so basically all superchargers and kits are related in some way through the origin of the rotors. Roots Supercharger. 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. Back to Article. Now shipping all Gen 3, Gen 4 and Gen 5 systems. Roots blowers tend to be only 40–50% efficient at high boost levels; by contrast, centrifugal (dynamic) superchargers are 70–85% efficient at high boost. In addition to the heat advantage from the better efficiencies, these maps … But a twin-screw supercharger compresses the air inside the rotor housing. It’s hard not to be impressed by the power potential of the GT500’s 5.4-liter engine. The blower dyno allows Kenne Bell to regulate all of the variables to properly evaluate the supercharger, namely blower speed, air temperature and pressure into and out of the blower, and the parasitic losses associated with driving the blower. I really think TRD hit it out of the park with this kit. This further reduced the vacuum in the induction system to 0 and increased the power output to 745 hp. 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. First, the originals with CFM conversions...then an overlay. Posted by on July 14, 2020. The 5.4 looked like a cardiac patient with hordes of wires running out of every possible orifice. … Roots and twin screw are both fixed displacement superchargers. MENU. 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. The Twin-Screw Design or the 4-Lobe Twin Vortices? Edelbrock’s Eric Blakely adds, “The internal bypass allows the TVS blower to be ‘unloaded’ during constant manifold vacuum periods thereby creating less parasitic drag on the engine. RE: Discuss twin screw vs centrifugal superchargers CH5OH (Petroleum) 15 Jun 10 13:08 a centrifugal compressor has only a good efficiency at the design rpm, to operate an engine on different rpm you can use a few turbo's with different design characteristics and … Stage 1 664 5.3 2.8 Mammoth Stock Stock Stock Stock 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. Of course, we also had charge temperature measurements and even test results from Kenne Bell’s own blower dyno. The front drive / front inlet design allows for a shorter less restrictive intake path allowing for improved air flow and superior performance. This test reveals that the TVS supercharger upgrade offered by Shelby on its Super Snake is a good bit more powerful than the factory offering. 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. Positive-displacement blowers (Roots or Twin Screw) are sensitive to inlet restrictions. 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). The TVS™ supercharger’s patented design features twin four-lobe rotors with 160-degree twists and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity and enable higher operating speeds. No longer applied only as a supercharging device used to increase horsepower and torque, TVS technology has reached a transition point, evolving as a tool with a range of applications across various industries. Buy the latest Samsung TU8500 55 inch Smart TV, check out price and specs of this 4K UHD TV with dual-LED, HDR technology & dynamic crystal display. While the power numbers alone confirm the blower hierarchy, here’s additional information provided by another form of dyno testing: namely, a blower dyno. (see Twin Screw vs. 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. 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. As with the M122, there was likely more power to be had with changes to the air intake and possibly a larger crank pulley. 3,500 513.35 342.10 585.25 390.02 71.90 47.92 701.07 467.20 115.82 77.18 Naturally, backup runs were recorded to verify the power numbers generated by each pulley size. [MORE] Are Front Entry Superchargers Really Better? These revisions have greatly improved not only the ultimate power and boost potential of the Roots blower, but the all-important average power production. The TVS does seem to have taken it to the twin screw guys recently. 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. Stage 3+ 801 0 2.8H Mammoth Kenne Bell Kenne Bell Kenne Bell Kenne Bell. Harnessing more than 600 lb-ft of torque at just 2,100 rpm would be difficult, but it’s always better to have too much than not enough. It also has a higher speed capability, from 18.000 to 24.000 rpm, which produces a broader map width. 3,000 501.39 286.40 565.46 {{{323}}}.90 64.07 37.50 672.43 384.10 106.97 60.20 {{{80}}} 92.96 35.40 The largest blower tested, the Kenne Bell 2.8-liter H-series, produced the highest boost pressure. VMP Gen3R TVS Upgrade Kit for 03-04 Cobra "Terminator" including VMP's Maximum Effort Options See more. 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. It's what makes it yours. These numbers are the rated flywheel power outputs just as the stock GT500 is rated by Ford at 500 flywheel horsepower. Twin-screw melt granulation offers the benefits of continuous manufacturing — providing a reduced footprint and improved economics — but with a greater degree of process control, with consistent product quality achieved through the implementation of different process analytical technologies (PATs). For a mainly street-driven car within the positive-displacement family, we like either a twin-screw or an Eaton TVS supercharger. [Main content. I went from TVS to KB 3.6.....I wanted to be like the rest of the cool kids...lol, I was close to pulling my 2.9 whipple off to run a ported/welded trinity ....actually had on my shelf for a long time going back and forth ...for once in my life I left well enough alone and now it's in the market section. Though enthusiasts tend to lump the positive-displacement superchargers into one group, there’s a significant difference between the Twin Screw Kenne Bell and the Roots-type Eaton. Is the restriction in the intake manifold between the rotors and the throttle body, the throttle body, the mass air, the inlet tube, or the filter? Light-emitting diodes result in a higher refresh rate, more contrast and brighter colours. The ROUSH R2300 TVS supercharger is a roots-type positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. Thats what we call a blower upgrade. Any vacuum present in the inlet systems costs you power. Who (you might ask) really needs 800 rwhp? The rotors on this system literally look like screws. “It’s a difficult area to measure, meaning the useful RPM range of normal driving – but a twin-screw supercharger tremendously increases performance in those areas, separate from even wide-open throttle. Luckily for us enthusiasts, the gang at Kenne Bell has spent long hours on the dyno replete with data logging at each point to determine where the restrictions exist, and then to produce the necessary products to cure the situation. The cars were driven on the same track, by the same driver, on the same day. UPDATE: If you swapped a stock blower to a TVS, please don't take the poll. "Stock" M90 look, but much more power. There is talk amoung Roush insiders/owners right now about a kit that Roush may have worked on that replaces the roots style rotors in the M90 on the 4.6L supercharger with the more efficient TVS rotors (half way between roots and twin screw). 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). With both systems available for the Super Snake and as upgrades for the standard GT500, it was only natural that we take a long, hard look at the performance offered by each. These runs help eliminate anomalies that can occur during testing. Tvs Vs Twin Screw. The more things change, the more they stay the same. Whipple Superchargers twin screw design makes them the most efficient supercharger available for making horsepower. Even the test vehicle (originally an ’00 Saleen equipped with a Two-Valve 4.6) has been upgraded to none other than the mighty Shelby GT500. The TVS™ supercharger’s patented design features twin four-lobe rotors with 160-degree twists and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity and enable higher operating speeds. Unfortunately for enthusiasts, positive-displacement superchargers are ultra-sensitive to inlet restrictions. 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).
