If you know anything about Eaton, you’ll know that they are one of the largest, if not the largest, purveyor of superchargers to both OEMs and aftermarket companies alike. Its blowers can be found atop some of the most powerful cars in the world. You may already be familiar with the TVS 1900 and 2300, huffers which topped the LSA, LS9 and Trinity respectively. But the TVS R2650 is officially on its way according to Eaton.

The new, larger 2.65-liter blower could be found on display throughout the show. From Edelbrock to Magnuson, the larger rotor pack is a hot ticket item and is anticipated to lead roots-style superchargering into the future. But it’s not just simply a larger version of the previous offering. There is no resting on laurels for Eaton, who has stepped up its game for the new unit.

The 2650 is only 350cc larger than the 2.3-liter blower that adorned the LS9 and Trinity, and yet it moves as much as 25 percent more air at the same 18,000 rpm while producing 14 pounds of boost. This adds up to a 6 percent increase in peak efficiency while requiring 18 percent less input power. This equates to more horsepower on both ends of the spectrum.

According to Eaton, the 2650 produces the low-down torque you’re used to with a roots-type supercharger but continues to pull relentlessly in the upper RPM range. Much of this is accomplished using physical changes to the rotor pack. For example, the R2650 is slightly longer than the previous 1900, 2300, and 1740 rotor packs. It also uses a 170 degree twist in each rotor instead of the previous 160 degree. This leads to improved sealing and thus improved efficiency.

And speaking of improvements, the timing gear teeth have been beefed up to handle greater torque loads as have all of the bearings. Pressure relief ports in the bearing plates reduce the amount of torque required to turn the supercharger per flow rate and a Delrin coupler ensures the R2650 can handle high torque loads.

Naturally, the blower has been tested to stand up to, and exceed, all OEM requirements-meaning this thing has been on dynos for well over 25,000 hours of validation testing. Obviously, this is one proven power adder.

The most interesting part of the whole thing is that the R2650 won’t be available in aftermarket superchargers until it makes its debut on the OEM application it was designed for. Obviously, we have our speculations and would say that its likely home will be on the new C7 ZR1. However, only time will tell. So if the ZR1 could just debut already, we’d really like to get this on something ASAP.
