What type of supercharger should I use on my car? There are a lot of options for forced induction, whether going the turbocharger or supercharger route. Superchargers typically will offer better throttle response, and can offer better low-end torque, however they ultimately are less efficient than turbochargers. But if you decide to go the supercharger route (great decision by the way), what's the best option? In this video we'll discuss the advantages and disadvantages of the four most common supercharger styles for today's cars: twin-screw, roots, centrifugal, and electric superchargers.

    Hey mate love your videos. I've always wondered would a twin screw charger be most likely considered a progressive cavity pump vs a positive displacement pump? It just reminds me of the fluid pumps build by mono which use a 2 flute rotor in a three flute stator to create a cavity that moves along the rotor? I could be barking up the wrong tree or splitting hairs but I'd love to hear your input on this classification

    Which of these arrangements would be most effective on a 400 hp class opposed piston uniflow diesel engine. The engine is to be used on heavy machinery (bulldozer/ore carrier) type applications. The engine is going to need supercharging at low RPM making the use of any single stage turbocharger problematic and the use of multistage turbochargers worrisome due to the increased number of parts.

    A jet engine is basically an air compressor, a fuel burner and a gas-driven motor, right? What if one were to take two Roots blowers; an intake compressor and an outlet power-stage, and put some kind of combustor between the two? Blower the first sucks in air to be compressed, combustor mixes fuel into air-steam and burns it, expanding gasses drive blower the second. Gearing/belts linking the blowers to keep the Entropy Gods happy. Heating might be an issue, but I kind of saw this as a dragster engine: short intense runs.

    I can't help but roll my eyes at electric superchargers. The whole point of a supercharger is to convert chemical energy to mechanical energy. Want more mechanical energy? Get a bigger engine, or get a bigger blower. You're expected to know what you're trying to accomplish. I like roots and centrifugal most. Roots for a responsive application. Centrifugal for a "planned" application. A twin screw blower requires a male and female rotor, which affects cost. Not the end of the world, but from a practicality standpoint, relevant.

    You said something interesting and I need explanation as a hyper-miler. You said there is a scenario where the engine is "not injecting fuel".. And I've heard reference to this before. I have a SCAN GUAGE (tm) connected to the OBDII port of all 3 of my vehicles. And in EVERY CASE, if I am on a highway, long downhill, and I shift into neutral, RPMs DROP (of course they do). My (automatic) Tundra will go straight down to 750 RPM and my MPGs go to well over 100MPG. If I were to stay in gear, the RPMs would be, say, 1800RPM and therefore my MPG would be about 70MPG. HOW does an internal combustion engine RUN, EVEN AT IDLE "without injecting (any) fuel?" On the Tundra, the SCAN GUAGE does occasionally report MPG of "9999" as if no fuel is being used, but that is momentary. My standard '96 Z28 NEVER shows that, and neither does my LS7 powered big cam vehicle.

    Hello Jason. Recently, I watched a few of your videos. Very interesting. Thanks for the content. I have a question, and a story. I have a little VW Up. It's a great little car, but it is a little sluggish. I had another Up last year, and a truck leaked diesel on the freeway, which led to me writing off my old car. I bought another one, and recently put bigger wheels on it, and now it's feeling sluggish. I'm not looking to go drag racing or anything like that, but what would you recommend to increase the power of the car a little? The car is still under warranty, so I can't make any big changes now, but after another two years, is it worth putting a small super charger in, or anything else. I like the engineering side, so be complicated, and give as many suggestions as you can think of. Thanks.

    Its not really that simple. Turbo don't necessarily mean high rpm power only depends how its sized for the engine. A properly sized turbo can have killer low and mid range torque. Many do twin turbo just to have smaller turbos for response but having two gives you the airflow to make some steam up top also. On the flip side the twin screws dont necessarily just have low end some of them can scream at high rpms and make badass power up top again depends on the size and how its sized to the engine among bunch of other factors. If you do compound boost like turbo and supercharger on same car itll make alot of power and a ton of torque but it will actually make less overall peak power than the same turbo(s) with no supercharger. It will have a ton more torque with both and still have a ton of power but less overall peak power vs a turbo only setup as weird as that sounds.

    So couldn't you fix the lag in a turbo by making a hybrid turbo with an electric motor to spool it up as soon as you touch the throttle and then have the exhaust take over at a certain RPM/boost or what ever benchmark you would use to switch over to exhaust. This would overcome the lag/cons of a turbo and you would still gain the efficiency of the turbo as soon as you come up to speed

    When I was growing up we always used a supercharger for low to mid range torque & horsepower. An the other hand, for mid range to high range torque & horsepower we used turbochargers. when we wanted low, mid, & high range torque & horsepower, we used a 15 boost turbocharger feeding air into the carburetors then into a GMC 6-71 roots style supercharger with a 30 p.s.i. pop off valve. We always machined a groove around each cylinder & some times around the combustion chamber on the cylinder head & used copper ringed gaskets to prevent head gasket failure when using a high boost pressure system. This probable reveals how old school I am. This was in the 1970's to the mid 1980's. At that time we were only running 9:1 pistons but now days you could run the same setup you could run 11 to 11 1.5:1 pistons because the material used for all the rotating parts have improved.

    @Boolean The combination of the turbo & super chargers worked out very well. It was a pain in the ass to find someone to make the intake pipes from the turbo charger to the custom made air filter housing on top of the carburetors. The super charger still compressed the air from the turbo charger at mid to high RPM but not as much. That's the reason you needed a 30 p.s.i. pop off valve on the super charger so you would not blow a head gasket or piston. And you had to play around with the timing and air/fuel mixture and the jets in the carburetors to get the performance you wanted.

    Isn't the power increase from electric turbos measured in House Power? LOL. These compressor designs have been around a while. Don't forget WWII military aircraft used centrifugal superchargers, so they could fly at higher altitudes. The roots type blower dates back to 1860 and the screw compressor to around 1878. Screw compressors were used in WWII submarines to change the air in the sub and to blow ballast. Nice to see they are still useful, but I prefer the compact, light centrifugal compressor. BTW, you left out axial flow compressors.

    i would build a battery bank that i charge while parked to supply 48v or 24v to an electric-supercharger. I think that would be +MPG and +electrical-efficiency over drawing from the (OEM) alternator... plus no loss in AC->DC. The limited capacity of the battery-bank should be just fine for legal street speeds. voltage monitor on the bank-output + fail-to-open supercharger-bypass in case of long-distance or failure scenarios.

    30 years ago I made an Electrical Supercharger, but it was just 12 volts and the power it added was almost zero. However most of cars today have the belt driven Centrifugal Supercharger with variable by pass valves that basically gives you a pretty straight boost along all RPM from 1800 to 6000! Your video must be old or just the basics.
