            It's not 1980 anymore, you can get low down torque with a turbo lol and I'm sure the traffic won't get away in the quarter second it takes for your turbo to spin up.

            Fully aware of the drag race scene, as well as autox, road race, land speed etc. Turbos have their use case, as to superchargers and prochargers. One of our cars holds a record in its class for land speed, supercharged, and beat out several turbo cars.

      >and for what benefit?
      Depends on the application and use case.

      The benefit of roots and twin screw superchargers is that since the charger is driven by the crankshaft versus exhaust gases, power delivery is instantaneous. Superchargers boost power across the rev range while turbos are peaky and have turbo lag. You have to use two turbochargers in a twin scroll setup to reduce, but not eliminate turbolag inherent to turbochargers.

      This is why American sports cars have traditionally used superchargers. GT500, ZL1, Z06, Hellcat all pair their V8s with superchargers. American V8s, especially the OHV V8s, make gobs of torque down low and don't rev high anyway. Supercharger gives a power delivery profile similar to naturally aspirated power. Pic related.

      Manufacturers that chase peak HP numbers in their displacementlet 4pots for spec padding use turbochargers. Turbos offer better fuel economy which is another reason they're paired in economy-focused engines. But superchargers offer smoother power increase.

          >Laws of physics go away after 30 years
          It's basic physics chud. Turbochargers have to spool up to compress intake air. They spool up with exhaust gases which is dependent on engine speed. Compounded with exhaust back pressure introduced by the turbocharger, spooling up takes time. With a twin scroll setup you can have one smaller turbocharger so it spools up faster but the turbo lag will always be there whether you like it or not.

            Firstly you brainlet... twin turbos are no longer a thing, they're only used for packaging reasons on V-engines or aesthetic reasons on inline sixes. For performance an appropriately sized single is better in every way - yes that INCLUDES spool time.
            Secondly turbos are most definitely NOT PEAKY, if you think they are you either don't know what the word peaky means or you don't know anything about turbos.

            An appropriately sized turbo should come on in a higher gear at ANY RPM ABOVE LUGGING, it will give you bulk midrange torque (that's the opposite of peaky btw) and unless you deliberately feed in extra boost it should drop off at around the same time the naturally aspirated engine would've dropped off.
            Turbocharged road engines (not race engines) will usually make peak torque at the point where the turbo FIRST hits full boost (not peaky).

            Turbos have turbo lag and are peaky. American V8s have a shit ton of torque down low and and don't rev high so a supercharger that gives substantial gains at low rpm while retaining the smooth power delivery advantage naturally aspirated engines have is a no-brainer. A turbocharger just removes the low rpm power advantage that those engines have and since the n/a V8s make a lot of power anyway, min-maxing power at the expense of engine feel is just moronic which is why American engineers have opted for superchargers over turbochargers. A fricking hellcat demon 170 can make in excess of 1000hp with a supercharger. Instant boost gives it a 0-60 of 1.66 seconds. No turbo lag needed.

            Most of the literature and thinking you're talking about is from the 80s though, when twin scroll turbos were the newest technology available.

            Turbo lag is a non issue on modern engines, and with variable vane technology (15-20 years old now) the torque curves are actually boringly flat, with peak torque usually from 1500-5000 rpm.

            Find the turbo lag here, I can't see it?

            Theres a time gap from when they hit the gas and when the turbo bar builds and stabilizes.
            If youre just driving around it doesnt mean much but if youre actually racing, it makes a difference which is why antilag exists and even that doesnt eliminate the lag completely.

        lol centrifugal superchargers are the worst of all worlds, they're usually used with intercoolers btw because COMPRESSING THE AIR is the main producer of intake air temperature - not the vicinity of the turbine housing to the exhaust.

          Centrifugals are the least likely setup to have intercoolers.

        compressing air heats it up. you dont need an intercooler with a turbo either. in both cases, you just pull a ton of timing unless e85 or better.

    The answer is because turbos are better in pretty much every single way. There's a reason why every manufacturer who ever made supercharged 4/6 cylinders don't anymore.
    The better question is why Americans still use superchargers on their high end V8s instead of turbos. Especially Ford, as if their dohc V8s wasn't gigantic enough that they needed to put a supercharger on it.

            Yeah, actually. The benz and bmw plants require intercooler removal to do anything and on the m176 for example its about 5 hours to remove them. The audi mill everything is on top of the engine and easy to get to. And if you wanna nag about timing chains the other production hot vs also require engine out to do timing.

        They're uncommon there because aftermarket is relative to market trends. If very few manufacturers are putting straight 6's in their vehicles, there's going to be very little aftermarket support for such a platform.
