Eaton has manufactured superchargers on the OE level for a very, very long time. They have got produced the power for some of the most well-known late-model muscle cars of this centuries, and really changed the Roots-style supercharger game with the Twin Vortices Collection high-helix positive displacement superchargers.

The latest model of the supercharger features a 3. 1-liter displacement (per revolution, hence “3100”) and is 15-percent larger than the previous iteration of the motorized inflator, the R2650, which has been used in the most recent crop of OEM-supercharged muscle vehicles and with aftermarket supercharger companies as well.

“The cool backstory is that this is the first supercharger Eaton has launched, that isn’t the effect of an OEM program, ” states Jeff Saxton, program manager meant for Eaton. “Virtually everything up to and including the particular R2650 were all OEM applications at some point or another; the aftermarket basically tips from that product launch. The particular 3100 is the first one that actually originated with the aftermarket saying, ‘We want something new. ’”

With Eaton’s customers asking for a bigger rotor pack, the team gladly obliged, designing the R3100 with all the best features from the incredibly effective R2650 — like the high-helix four-lobe rotor design and coatings to reduce friction in the assembly — plus scaled it up. The result is a supercharger capable of significant power increases each through the physical size increase from the unit, and increased efficiency with the use of coatings which create “near-zero” clearances.

Eaton’s supercharger companions will be releasing individual new products offering the R3100 rotor pack beginning early 2021, but as we have seen here at SEMA 360, there are several manufacturers who already have their item application and announcements ready to stone.
