    • Kong Performance LSA and LS9 TVS2650 supercharger swap kit - Easy 1000+ horsepower capability

      Both the LSA and LS9 V8's come supercharged from the factory. The LSA has a tiny 1.9 liter roots TVS blower and the LS9 sports a 2.3 liter roots TVS blower. Owners no doubt are jealous of the monster TVS2650 that the C7 Corvette ZR1 utilizes.


      Well, Kong Performance has a solution for those owners. A TVS2650 conversion for the LSA and LS9:


      Kong Performance is proud to introduce the Kong LSA TVS2650 Supercharger. The Kong LSA 2650 has the same height as the factory supercharger which means hood clearance is not an issue. No modifications are required.

      Details:

      The TVS2650 is equipped with a high twist, 4-lobe rotor design. These rotors are 40% larger than the LSA TVS 1900 and feature several improvements to maximize efficiency and performance. The TVS 2650 is the largest Eaton TVS Rotor pack on the market.

      Supercharger Lid / Intercooler

      ***This Supercharger does NOT include a lid or intercooler*** The Kong LSA 2650 is machined to retro fit any LSA or LS9 style lid. Before and after testing showed no noticeable increase in IATs when compared to the original LSA Supercharger.

      Other Information

      -Compatible with LS style throttle bodies up to 112mm.

      -Machined in O-ring to manifold style gaskets allow for easy installation of the supercharger.

      -Kong LSA 2650 specific supercharger pulleys will be required when purchasing the unit. They can be ordered by clicking this link ---> HERE.

      -Compatible with any LS engine using an LSA belt drive with LS3/LSA/LS9 style Cylinder Heads


      What kind of efficiency gain are we talking? Well, on a built LS9 swapping over to the Kong 2650 netted 130+ rwhp and pushed the car to 1071 to the rear wheels on a Mustang dyno:


      Definitely a great way to bring an LSA or LS9 into modern LT5 territory.

        This thing is a game changer and has breathed new life into the V2 CTS-V for sure. A bunch of people are buying them that would have otherwise had to cut up their cars to put a turbo kit on.

        Even cooler is the Kong dual pass intercooler lid that fits on this blower (and is backwards compatible to stock LSA/LS9 blowers).
        For LS engines because the V valley is so small compared to DOHC engines there is always cooling issues with large aftermarket blowers. This is why the huge 3-4L blowers need methanol and stupid $#@! to actually go fast they just generate way too much heat it pulls timing.
        This will for sure make 1100-1200whp and consistently.

        This is the intercooler that is in final testing now and should be badass.

        Makes complete sense.
