    A supercharger consume alot off power to make power while a turbo don't.

    A turbo is supreme as long as you don't operate on low load.

    Why not combine it in a two step configuration?

    Supercharger as step one charging a 1bar and a turbo as second stage charging at 1bar.

    The charger would feed the engine while the turbo is not in it's operational area. Once the turbo kick in it will take the load off the supercharger.

    once the turbo is charging 0.5bar the supercharger will only have a delta p off 0.5 bar. once the turbo is charging with 1bar the delta p off the supercharger is 0bar and therfor only require power to compensate for loss in mekanism and not efficensy.

    Think radical and not traditional.

    Almoust, but I was not sugesting bypasing the supercharger but let it continue running, but without load since the turbo is doing all the pumping.

    That would eliminate some off the controls neaded for the TSI.

    No?

    If you kept the supercharger running, you'd never make more power than the supercharger would allow, since it's bottlenecking airflow.

    yes, but if your charger only put out 1bar and the turbo is doing the same that would newer be a problem.

    If you do you could allways use two step turbo with a supercharger betwen the two turbos and make a inductionsystem far more expensive then necesary.

    So if you wanted to run the same amount of boost through the turbo, then why run both? It'd be adding weight and complexity for the sake of weight and complexity.

    removing turbo lag without having to lose power on constant running the supercharger on load. once the preshure on the delivery side drops delta p will drop and the supercharger will get unloaded.

    No other reason.

    Complex? no. easier then the vw system and a lysholm weights less then the car entertainment lots off people ad.

    But if you're running a turbo set up to run ~15psi, you won't need a very big motor to have good spool characteristics. The 2.0T FSI motor runs about 15 pounds, and it's a very low-lag motor.

    It just seems that if you unless you want to run a massive amount of boost with little to no lag on a tiny motor, twincharging isn't really necessary.

    Who says I don't know them? You said 1 bar, which is almost 15 pounds. Big deal.

    I say both a turbo and a supercharger. Take the Lancia Delta S4 car built for Group B, it employed both and the result was an amazing engine with a near ideal tourque curve.
