    Why are you so concerned that members think you're smarter than me?

    It's odd. So I did some more research and I found this.

    You take idiotic positions arguing with me and I enjoy rubbing your retarded nose in it. It passes time while I have nothing better to do

    :pc:  Agree not common what so ever they are calling it a wastegate to control intake pressure on a supercharged engine.  Doing it in reverse but could be done.  

    https://www.motortrend.com/how-to/sucp-1211-supercharger-wastegate/

    "With the wastegate, we can spin the blower faster to produce greater boost, and bleed off the extra pressure that's not necessary," says Borschke. "This allows the boost to come on much sooner, gaining midrange power--especially torque--that you can really feel on the street. But more importantly, it helps maintain the right boost for to prevent detonation in a stock engine.

    Strange that they call it a wastegate. I guess if they are venting it to atmosphere that definition could fit. Typically it would be dumped back to the intake side of the compressor wheel and would be a recirc system like what’s used in many cars instead of a bov

    I simply asked you where you found this specific definition and to provide a link here. Yet you haven't backed it up yet. Why is that sooooo hard? You said it's 100 years old :dunno:. Is it because you made it up???

    Turbocharged has a specific definition and that means it makes a pressure above 1 atmosphere.

    You’re too fucking stupid to understand what one atmosphere means. If you examine the definition of normalizing it’s easy to extrapolate what charging would mean and it’s exactly as I stated it.

    You can't run a Vortex style supercharger thru a wastegate to control manifold pressure?

    It wouldn’t be a wastegate on the charge side. I’m sure some type of electronically controlled recirculating valve exists in some sc setups but it’s not common or commercially used

    Well if I'm using a Turbo to charge the air then my definition is its being turbocharged.  I don't care if the definitions overlap one another. :bc:

    I just think it’s an easy thing to delineate. Using a turbo to maintain sea level power is normalizing. Using a turbo to exceed sea level power is charging. Almost anyone with an aircraft background would agree with that.

    So if a supercharger doesn't raise manifold pressure above sea level atmospheric pressure then its super normalizing not supercharging?  :lmao:

    Again I get what you are saying and people are splitting hairs here. 

    I mean it’s simple 

    Are normalizing and charging two distinct things? I think I’ve shown that to be the case and most who haven’t been into airplanes probably wouldn’t have known. 
     

    If you accept that they are two distinct system designs utilizing largely the same components then it would be correct to describe skidoos original system as normalized and not charged. 
     

    Also about the only way a supercharger can fail to raise manifold pressure beyond 14.7 psi absolute is if it’s missing the belt lol

    :pc:  Wiki but still defines it correctly.  Techically every foot of elevation changes atmospheric pressure very small amount.   

    In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder. The density of the air charge, and therefore the engine's maximum theoretical power output, in addition to being influenced by induction system restriction, is also affected by engine speed and atmospheric pressure, the latter of which decreases as the operating altitude increases.

    This is in contrast to a forced-induction engine, in which a mechanically driven supercharger or an exhaust-driven turbocharger is employed to facilitate increasing the mass of intake air beyond what could be produced by atmospheric pressure alone.

    Nobody said a normalized engine wasn’t a forced induction design. Of course it’s utilizing forced induction. Just not to the point of exceeding sea level power output.

    Can you give me an example of that?

    My example at some point changes manifold pressure with the use of exhaust gases driving a turbo impeller.   The pure definition of turbocharging. 

    Ben I get what you are saying but your hatred of how Skidoo was doing the first turbo mountain sled does not change what it was doing.  Increasing manifold pressure by the use of exhaust gases driving a turbo.  The level of pressurization need not matter. 

    Go ahead and sue BRP for faulty advertising and see if you win.  :lol:  

    I’m simply saying , turbo normalizing and turbo charging are two different things. The terms were put into common industry nomenclature by the aircraft industry who were the pioneers of commercial turbo use. What skidoo did in 2020 is a text book definition of turbo normalizing. What they did in 2021 is a text book definition of turbocharging. It’s not hard to concede

    I've stayed out of the topic for the most part. It says right in his link the turbo normalized motor is different. There is more to it than just adding boost to distinguish it as a turbo charger and not a normalizer.

    No , that is an example of what that specific company may change. The reason I posted the link was to illustrate they are two distinct designs. Quit being a know nothing dumbfuck retard

    Holy fuck :lol:

    He is so fucking Stupid it makes my head hurt. 

    The fact the compression ratio isnt lower proves it all. If the thing made any sort of good boost it would NEED lower compression.

     

    He’s just too dumb to grasp any of this , much like HSR. Yet here they are arguing anyways.
