    • 4.5 liter Whipple upgraded Trackhawk vs. stock McLaren 600LT drag races

      This video comes from Hennessey so keep that in mind. They pit their '1000' horsepower Trackhawk against a stock McLaren 600LT. After a brief intro explaining to us the differences between sports cars and SUV's they line the cars up on the strip.


      The first run easily goes to the Trackhawk as the 600LT was not launched with launch control.

      The second run has the 600LT get the hit and with launch control it makes easy work of the Trackhawk.

      They decide to give the Trackhawk the hit on the third run but the 600LT would not engage launch control. There likely is a cool down period but regardless the Trackhawk opens up a nice lead only for the 600LT to run it down.

      What do we learn from this? A stock 600LT is a monster and you better have over 1000 horsepower in your Trackhawk if you want to play with one.

      We also learn Hennessey is calling the Whipple 4.5 liter twin screw his own supercharger upgrade. You likely would be better off just getting a Whipple (or a TVS2650) and cutting Hennessey out of the process altogether. Unless you really have a thing for John Hennessey's signature on interior plaques and overpaying for superchargers others developed.

      4.5L Supercharger system producing 14 psi boost

        Pretty sure Hennessy always rates his pckgs @ flywheel 'enhanced' HP, not RWP. Soooo, it's prolly more like 850-ish to the tire-maybe? I didn't Google specs on each, but that Jeep prolly weighs like what...maybe 1,500lbs more than the 600LT? I've never been a fan of Hennessey's overpriced/overhyped products.

        Hennessey is so egregious about it because they don't even develop any of the expensive components.

        I never understood how tuners that are so overpriced can stay in business until I found out a co-worker of mine spent over 2k on a Dinan piggyback for his M3 Click here to enlarge

        That's pretty much it. Most people just don't know.
