Eaton today introduced its Twin Vortices Series TVS X3100 supercharger for aftermarket applications. The only unit ever showcased came affixed to a kit from Magnuson Superchargers in a gorgeous 1957 Chevy Bel-Air on display at Eaton’s SEMA booth. A fully built show and drag car called “Big Nasty” has been blessed with the first TVS X3100 supercharger production unit ever to be shown.

Powered by a Dart LS SHP engine and banging gears via a Rossler Pro-Mod 400 transmission, Eaton staff reportedly saw the 1,100-horsepower Chevy smoking its rear tires at 80 MPH during testing. And that’s just under a modest 20-pounds of boost!

With its Detroit TrueTrac Ford 9-inch rearend, Strange center section, and 35-spline combo, this beast of a ’57 is both a show car and a straight-line animal all in one. However, it all spins around those new Eaton internals, and here’s why…

What Makes the TVS X3100 So Special?

Looking to dig into the details a bit, we spoke with Eaton’s sales team at SEMA about this new Magnuson blower setup, and what we found was impressive, to say the least.

First of all, the X3100 is the direct result of customer demand. Aftermarket enthusiasts crave greater airflow, but due to chassis constraints, they can’t always accommodate a massive motor package. This is why Eaton engineered its TVS X3100 rotor pack so that only slight modifications must be made to an existing supercharger housing. The result: superior fit and tons of tuning potential.

Then there’s the performance part of the puzzle. Eaton designed its new triple-lobed rotor to reduce parasitic loss, with the company’s “high-twist” design reportedly moving 30 percent more air than the R2650. Naturally, these gains are made with the same pulley speeds and sizes.

Here are a few more facts about how the new Eaton TVS X3100 blows the R2650 out of the water.

• 17 percent larger displacement (3100cc vs. 2650cc)
• Over 30 percent more airflow at 18,000 RPM and 14 psi boost (2.0 PR)
• Approximately 11 percent more overall volumetrically efficient
• Can spin extremely fast, with 24,000 RPM being easily achievable

“The all-new Eaton TVS X3100 is the first rotor design developed specifically for the aftermarket and not for an OEM. The three-lobe design of the V-Series maintains engine packaging size, while the high-twist design from the R-series improves the high-speed flow efficiency. Ultimately, the X3100 pushes more air at the same power input as the R2650 and can be tuned by our customers to their specifications,” says Tim Bauer, vice president, Eaton Aftermarket Vehicle Group North America

Supercharging SEMA

For those in attendance at SEMA this year, you can find this core component inside an all-new Magnuson supercharger kit on the 1957 Chevrolet pictured here at the Eaton booth. This car was originally rocking Eaton’s R2650 but was selected to serve as the “spinny pig” for the all-new X3100. Talk about one lucky ride, right?!

That being said, this X-Series was developed specifically for platforms and aftermarket enthusiasts of this caliber. It was also built upon the successes (and shortcomings) found within Eaton’s R-Series and V-Series rotors.

Look for Eaton’s new rotor package to become available in the near future from a number of different supercharger manufacturers.
