    • The Lexus RC-F is a joke - BMW F82 M4 DCT vs. RC-F roll on

      It is always important to question this source when a 'stock' BMW M car is shown obliterating whatever it is racing. However, in this instance there is nothing difficult to believe as the Lexus RC-F is a giant pile of fail. Plus, we have already seen this race from another source.


      The run in the video here is a bit longer and the M4 stretches its legs by putting football fields on the RC-F.

      Based on comparisons going back as far as 2014 the RC-F showed it was never in the M4's performance league. Which is a shame as it would be great to see a naturally aspirated entrant in the segment offering real competition for the Germans. Only the Americans offer a real challenge there if you consider a Mustang or a Camaro to be in the same class.

        Exactly. Wake me up when they do something of merit.

        Well, I guess that's basically the same thing as an RC-F.

        Love the look of the RC-F but lack the torque of a turbo engine.

        Something RR racing can cure I think (but 10k)

        We are excited to announce that after over a year in development and testing, multiple track days, desert testing, and over 10,000 miles of punishment and tuning, we are finally ready to release our RC F/GS F Supercharger kit! Our goal for this kit was to maintain stock drivability and reliability, while creating smooth, seamless, and unrelenting supercar levels of power that these great car deserves.
        RR670 Kit Specifications:


        • Power: For the base "RR670" kit, our customers can expect to make about 670hp at the crank, or 560 to 570whp (wheel horsepower on a Dynojet dyno, SAE correction -- see Dyno result chart in the product photos gallery) at approximately 6psi peak boost pressure, 93 pump gas, equipped with standard PPE headers and a high flow dual exhaust.
        • Tuned ECU: We have logged countless development hours perfecting our ECU tune for the RC F for ultimate reliability and drivability. No piggybacks or other BS! We have extensively developed the mapping of the stock ECU, modifying literally hundreds of maps and adding additional functionality to the fueling system that allows us to support up to 570whp without fuel system modifications.
        • Supercharger: Rotrex Supercharger, c38-91 (largest Rotrex SC). Rotrex SC's are extremely efficient and quiet due to their planetary drive system which spins up to 90,000 rpm, much like a turbocharger.
        • Dedicated Drive System: Rather than using the accessory belt to drive the SC, we designed a dedicated drive system that allows us to achieve the necessary belt tension for a reliable SC drive, without overstressing the alternator, water pump, and AC bearings.
        • Custom Harmonic Crank Damper: There are some overpriced Japanese SC's on the market for the ISF/RCF that eliminate the factory harmonic damper crank pulley and replace it with a simple machined aluminum pulley. We find this simply unacceptable! Working in conjunction with ATI Performance, we developed a custom tuned harmonic damper than drives the SC belt. The ATI damper has been specially developed to dampen the harmonics of the 2UR-GSE engine at high horsepower levels for the ultimate in engine reliability.
        • Billet Tensioner System: Most SC kits on the market use OEM belt tensioners, but we took that a step further by developing a billet belt tensioner that is both more reliable and is able to apply significantly higher belt tension than conventional off the shelf tensioners. For added reliability we use Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys.
        • Dual "Big Bubba" billet blow off Valves: We use not one, but TWO Turbosmart "Big Bubba" 2" blow off valves. Adequate venting is essential for SC responsiveness, reliability, and drivability.
        • Custom Air/Air Intercooler: We use a large 4.5"x12"x10" intercooler core. These intercoolers are extremely high quality and are manufactured in the USA by Bell Intercoolers.
        • Genuine Carbon Fiber Intake Tubing: All visible intake tubing is made from genuine twill weave carbon fiber for an amazing look and function!
