Series Archives: TVS

Eaton’s Twin Vortices Series (TVS) superchargers are the successors to their highly successful and popular M-Series product lines. At the time of writing the TVS Series are Eaton’s 6th generation roots style blowers. The TVS line includes two subtypes: The R-Series which incorporates 4 lobe rotors that are optimized for single stage performance at high speed and high-pressure ratios. The V-Series uses a 3 lobe rotor and is optimized for low engine speeds which Eaton states are ideal for 2-stage or compound boosting systems such as a turbocharger and supercharger setup. A TVS unit was unveiled at SEMA 2006 and the first production car to use a TVS blower was the 2006 TRD Aurion (Toyota Racing Development) released in Australia.

Eaton Announces the TVS R2650

Eaton announced the TVS R2650 which is the latest addition to their TVS roots blower series. The announcement took place at the 2016 SEMA show.

Eaton’s R2650 is not just a larger displacement TVS. It comes with a 4 lobe optimized rotor design that uses a 170 degree twist which reportedly shortens the rotor lead which helps maintain peak efficiency with higher speeds and pressure ratios. The optimized length over diameter ratio is said to improve sealing. To increase durability Eaton has added thicker timing gears and larger bearings. Additional efficiency comes from pressure relief ports in the bearing plate to lower required input power. The end result is the largest supercharger rotating group ever produced by Eaton with improved efficiency and air flow in the upper RPM range without adversely effecting low to mid range RPM operations.

Eaton says the R2650 was in development for over two years and has over 2,500 hours of testing using SAE standards. They believe that no other aftermarket supercharger can meet its durability.

R2650 Improvements and Changes Over the R2300 Include:

  • 18% less input power needed.
  • Nearly 6% more efficient.
  • 15% larger displacement.
  • 25% increase in air flow at 18,000 RPM and 14 psi boost.
  • TVS R2650 (Roots) by Eaton
  • TVS R2300 (Roots) by Eaton
  • TVS R1320 (Roots) by Eaton
  • TVS R1900 (Roots) by Eaton
  • Eaton Goes Smaller To Get Bigger

    Recently Eaton has been paving new roads with their forward thinking supercharger product development. They have been concentrating on a market that has the most need and demand for specialty blowers. They are developing superchargers for small displacement gas engines.

    Eaton's TVS (Twin Vortices Series) Supercharger

    Eaton is expecting big things from small engines using the TVS Supercharger – Their twin vortices, four lobe roots type positive displacement blower.

    With this in mind they are challenging two very firm beliefs: One, is that superchargers are only for big horsepower and performance vehicles. Two, is that turbochargers are the best option for small
    displacement stock engines.

    Turbos are currently the choice of many large manufacturers who want to add power to their vehicles but Eaton has been able to prove that turbochargers may not be the best option. Eaton claims their current roots type positive displacement supercharger can not only improve engine performance but they also provide up to five percent in fuel savings, reduced emissions and are considered maintenance free – all without the annoying lag of a turbo.

    Eaton’s real world examples on small vehicles include the 2011 Nissan Micra which is a supercharged 1.2 liter, 3 cylinder micro car sporting the twin four-lobe rotor Eaton TVS® blower. China’s Chery Automobile Co. jumped on board with some of their 2010 line. The Chery 1.6S Tiggo compact SUV with a 1.6 liter blown engine producing 148 horsepower @ 5500 RPM and 151 lb-ft of torque between 3500 – 4500 RPM, the compact 1.3S A3 which is supposed to perform like a 2.0 liter engine and the small sedan Riich 1.3S G3.

    The extra power provided by Eaton’s superchargers works out to be an ideal fit for these small engine applications. It allows auto manufacturers to produce a smaller power plant which allows for a more compact vehicle while keeping the same horsepower with lower emissions and improved fuel efficiency.

    Eaton is poised to take advantage of the global trend towards smaller and more efficient vehicles, especially in some of the largest automotive markets in the world. Now that they’ve built a relationship with Mazda and have a foothold in China, which is the largest car market in the world, they have their sights set on other manufacturers and countries.

    Rumors indicate one of those markets is India. Eaton is already established there but reports say they are working on a deal with Tata Motors to produce a supercharged Tata Nano. Eaton’s insight and new partnerships has them going from a shrinking supercharger market to expecting sales to double by 2015.

    Supercharger Kits to Watch for at the 2010 SEMA Show

    Along with some great supercharged vehicles there are a couple supercharger kits planned for debut at the November 2nd to 5th, 2010 SEMA Show in Las Vegas. Here’s a look at them.

    The ProCharger Stage II System and Tuner Kit for 2011 Ford Mustang 5.0l.

    ProCharger strikes the hottest iron which seems to be the 2011 Ford Mustang GT 5.0l. This well established company is debuting an already available supercharger kit the ProCharger Intercooled Stage II System and Tuner Kit. The kit is 100% complete and includes a P-1SC-1 ProCharger self-contained centrifugal supercharger, a front mounted 3-core air-to-air intercooler and a 8-rib dedicated supercharger drive system (a 12 rib is supposed to be available as well) and it all fits under a stock hood. The complete package is supposed to provide 7+ psi of boost and 180 HP to a stock engine running high quality pump gas. When all is said and done ProCharger says your stock 2011 5.0L will be pumping out 615+ flywheel horsepower with their new Stage II Supercharger System and Tuner Kit.

    Magnuson is also gunning for the 5.0L Mustang crowd with their 2010 SEMA Magna Charger debut. The company is keeping quiet about their new system but many speculate the new kit could be based on the TVS 2300 blower which is used in the Roush and Whipple supercharger kits. They have leaked some pictures. Shown is the new kit in grabber blue. Rumors have it the final product will be available in blue, black and chrome.

    Twin Supercharged Challenger

    It takes a bit more than the standard supercharger kits to get a horsepower monster like the RDP Challenger SRT8.This Dodge is pushing out 1000 HP running a one-off custom twin supercharger system.

    Picture of RDP's twin Harrop supercharger setup on a Dodge Challenger SRT8

    Early in 2009 the RDP Challenger took the title of World’s Fastest Late Model Challenger by running 10.24 at 133 MPH. Later they bested that run and reached their goal of a single digit quarter mile with a 9.79 at 144 MPH. The RDP Challenger also had a record for most powerful late-modern Hemi.

    To push the 2010 SRT8 Challenger to these extremes RDP had to do some custom work on it. Here’s some of the specs:

    • Twin RDP Harrop HTV2300 Supercharger System (Roots Type using Eaton TVS internals)
    • Arrington 440 Hemi Stroker motor with a custom RDP camshaft
    • Factory transmission with a RDP transmission control module
    • RDP 4000 RPM street/strip torque convert
    • Quaife rear end with RDP 1200+ RWHP 1/2 shafts
    • Big Daddy chromoly half roll cage
    • Kooks Long tube headers
    • RDP Custom race exhaust system with RDP mufflers
    • Nitrous Express with custom RDP nitrous plates
    • Street trim

    Since then RDP has released an updated version of the Challenger running twin turbos on a 426 SRT8 that is reportedly pushing out 1,300 RWHP.

    Here’s some great videos of the RDP Challenger:

    2000 Ford Crown Victoria LX Superchargers

    I have a 2000 Crown Victoria LX am I’m looking for a Supercharger set for it. Right now, I have not found anything and have no luck. If you have any information, please send it.


    The stock 4.6L V8 in the 2000 Crown Vic is a 2-valve SOHC (single overhead cam) which is the same as the 2000 Mercury Grand Marquis with 215 HP and 285 lb-ft. Crown Vics use the same 4.6L Ford Modular engine as many Ford products do. For example the Mustang. The 4.6L 2-valve SOHC were used in Mustangs from 1996 to 2004 and other cars using this engine were 1994 to 1997 Ford Thunderbirds and the 1994 to 1997 Mercury Cougar. So, if you can’t find a supercharger kit for the set up on your specific platform then you can look at the other cars for options.

    Luckily there are already Crown Vics with superchargers. A popular option for them seems to be the Eaton M112 roots blower. There is a company called Tork Tech Inc. who produces an Eaton M112 based supercharger kit for the 4.6L Crown Vic. They have their kit set up on several Crown Vic’s but it’s not a simple as pie bolt on. Some changes need to be made such as moving the battery to the trunk or drivers side as well as moving the coolant overflow tank and washer fluid tank. In the grand scheme of things these aren’t major problems to overcome so it’s a really good option to look at.

    The Tork Tech supercharger kit may be the easiest way to get it done but I can’t say if it’s the most cost effective. Rumor has it the price is a bit up there. As for other options I’ve also heard that Whipple may have something for the 4.6L so you could check with them. Finally, following is a video of a 2000 Crown Vic with a Vortech V-2 SQ S-Trim centrifugal supercharger which seems to be a custom install.

    If anyone else knows of some superchargers or kits that’ll work on this platform please leave a comment.

    Eaton Corporation Logo (™)

    Eaton Corporation has roots back to 1911 when Joseph Eaton, Henning Taube and Viggo Torbensen founded Torbensen Gear and Axle Co. The company started off in New Jersey, USA producing seven hand built axles in their founding year.

    Eaton went through many changes in the early part of its life including several name changes, a headquarters move to Cleveland, the sale and then repurchase of the company and several acquisitions of competing and complimentary businesses. Through the years Eaton continued acquisitions that took them far beyond the automotive industry. This expansion has lead Eaton Corporation to sales of $11.9 billion USD in 2009.

    When it comes to superchargers and supercharger kits, Eaton has remained loyal to the Roots style blower. Since the 1980’s Eaton has produced over three million Roots superchargers for street and strip. What makes Eaton’s Roots superchargers stand out is their designs. One of Eaton’s designs, the Twin Vortices Series™ (VTS™) was able to improve fuel efficiency, increase power, reduce noise and vibration and provide a smoother and more efficient air flow. The kicker is they were able to do it all in a smaller and more simple package than many previous Roots-type supercharger kits.
