    • RR-Racing Stage 3 Lexus RC-F & GS-F 2UR-GSE V8 supercharger kit hits 678 rwhp on E70 ethanol

      BoostAddict wrote about RR-Racing's 2UR-GSE 5.0 liter V8 supercharger kit back in 2017. Back then, they were hitting 568 rear wheel horsepower on supercharged Lexus RC-F and GS-F applications. To be noted, they can supercharge the IS-F as well but it makes a little less power.


      Well, with a higher boost pulley and E70 ethanol along with new tuning for their Stage 3 package RR-Racing is now clearing 678 horsepower to the wheels on this 2016 RC-F:


      The (gorgeous!) hardware features the same Rotrex C38-92 blower but at ~9 psi of boost.

      They essentially maxed out the blower but they will update the kit with a Rotrex C38R head unit. You can read the C38R specifications here.

      These results are all on the stock motor but they have built motors as well running supercharger kits and things should get interesting when the C38R's are pushing higher boost.

      For Lexus performance enthusiasts who want to hang with modern performance cars and namely German rivals, this supercharger kit is a must.
