no wonder people make the mistake though. superchargers are in essence turbochargers. They force feed air into the manifold and are turbine driven. However they use the belt system to spin the turbine rather than using the exhaust like turbos do.
Twin scroll???? Man some people here need some basic engineering instruction........lol. It is not twin screw and it is also not a twin scroll, it has no turbine side which is why a turbo is called a turbo.
Christian Angeles I was about to say haha it looks more like a turbo but I’m not a car guy but I knew there was different superchargers positive displacement is the only I’ve had the joy of installing and using one of those with a blower haha
stock 252 kw-, 343 hp european version. Never touch a naturally aspirated engine like this one. this M3 e 46 is a masterpiece from bmw. The last real M3. That guy is crazy
what heats up the air in a turbo/supercharger is the compression of the air itself, the more you compress it the hotter it gets.. that why intercoolers are good in both!!
Exhaust from the engine have to flow inside of turbo to make the turbines spins. When the turbine spins, the other end of turbo sucks in air. The air (boost) goes into intercooler and back to intake-manifold. Supercharger is belt-driven by the engine. Basically, when the belt spins, the superchargers impeller spins and it sucks in air and makes the boost and then through intercooler and back to intake-manifold. If I explained it wrong correct me. Have a good day.
That is sweet... was screaming/almost... at the inner cooler, but since it's running of the crank, there's constant boost, with out the drop off from running off the exhaust!! . Massive gains!!
Turbocharger can apply more pressure easily than a supercharger and it is mostly more efficient, because the Supercharger is belt driven. Although the Turbo has a lag when hitting the gas pedal where the supercharger has immediate response.
you still need blow off valves on a supercharger to stop the pressure surge when the butterfly valves close damaging the compressor blades. Turbo's are powered by exhaust flow, superchargers are powered but the engine timing belt. All turbo's look the same (sea shell), but there are different types of superchargers, this one is like a turbo compressor
Of course there's ecu changes they've just made cuts in the vid. Supercharger kit takes around 10 hours to fit not 8 mins. Also there's 4 different ess tuning SC kits available. Any and all supercharger kits require you to send your ecu to there company to re-program or they'll send you the remap file via email so you can flash it yourself.
its basically a turbine design blower, what they call a "Centrifugal" supercharger, & yes it does use a blow off valve, & sounds kind of like a turbo, except it is belt driven like a supercharger vs exhaust with a turbo,
Its a super charger, Its a centrifugal supercharger so it compresses the same way as a turbo however its belt driven, since it compresses the same way there needs to be a blow off valve and intercoolers are on both supercharged and turbo cars. Its a vortech supercharger google it.
DirtyDan turbos need intercooler not beacuse hot exaust but because compressed air gets warm and warmer air is less dense than colder, hence colder than the itake air, more power to the wheels. Supercharger also compress air and if you want more power you get intercooler. On the turbos, turbine section is wery hot (it can come to 800C), but only 10-15% of this heat is transfered to the intake air.
+Peter HMan I've only just seen this, yes treating me well I love the car but looking at moving it on for a family friendly car now. it's on carsales now.
Peter HMan do you think the money was worth it? Was it really that noticeable power increase on the street? What made you decide to go with ESS? Cheers
How it is attached to the engine belt? It's got its own belt but on what does he put the other side of belt? And it sucks air through air filter which is now behind bumper, and what next? I mean, does the air flows then to the radiator and then to the manifold? (I'm not an expert, I'm just asking :) Btw nice video!
who drives a supercharged m3 through a flood? that's like saying you can never drive a Ferrari down a country lane because you don't have the ground clearance.
There is very little room in the engine bay for an exhaust powered turbo and on top of that only one company makes a kit that I know of and that is hpf. You have to send them you car and they take the entire engine out and tune it for you in stuff but the basic kit starts at like 16000 or something like that
i believe all e46 bmw's have a plastic cover beneath the engine.. so that air filter sucks air that gets in from the front bumper/ what gets through the intercooler.
Bmw engines are mostly strait 6's and so the super charger wwould most likely not mount on top like most other cars, but a pro charger kit looks like a turbocharger and sounds like one but is still driven by the belt, and not all super chargers need an intercooler, in fact most don't. Unlike turbochargers which require one along with many other components. This is because the supercharger isn't spun by exhaust gases so theirs no need for cooling. Hope those cleared up some questions.
Dirty Dan -Procharger is a brand name ALL compressed air is heated whether its a turbo or a SC, so having an intercooler means denser charge means more power.Most SC do use a FMIC unless they run methanol or water injection to cool the air, some run all.
correct me if im wrong; this sounds alot like a turbo charger. blow off valve, the blower, inter-cooler, boost levels, etc. the video is labelled supercharger.
Jay Bond Both right xp just depends on what you call an intake xD The manifold is the air intake on the engine itself, the filter is the air intake from the entire system. Anyway, the intercooler is there to cool down the air *after* it was compressed.
Just to explain.. mariomaster281 and others.. New Stock BMW M3 has 343 HP, thats 275HP at wheels.. they measured 191kW = 260HP so it's down to 15HP on wheels in comparison to new car. Not bad, M3 have actualy more power (like 350 and 374 for CSL) when new as stated by BMW, and that's not a common thing in today's cars.. (Toyota is known for -15% when new in comparison to paper). So after this modification it has 307kW on wheels so that's 520HP engine? Hard to believe.. but it's possible. PS: Supercharger is not a turbo charger driven by belt. Turbine is driven by gas and as there isn't any in supercharger, we talking here day and night.. Supercharger has compressor driven by belt (or electric motor) and turbocharger has compressor driven by turbine.. get is straight, read wiki. Piiisss
181KW is roughly 250HP and even taking into account gearbox/transmission losses, it's down about 40HP on what it should be. 338HP - 15% = 287.3HP. Wat. My old car was recently dynoed and made 225HP at 84,000 miles. It was rated for 223 at the factory. The tuning place informed me that modern cars don't really lose power. What the hell's going on here?
so if youre gonna have a pulley powered turbo-like compressor (with all the accessories that a turbo requires) why not just put an exhaust powered turbo? great vid btw.
Autotechengineering, don't the Eaton superchargers achieve much better fuel economy by comparison? Which supercharger would you say is the most efficient? Which one has an efficiency approaching that of a turbocharger?
Its about right for these cars here in AUS - our Dyno's read lower then US & EU dynos. For example, a C63 with 500hp in the US only just makes 420hp here.
Hi,so how do you control the boost on this superchargers,do you need to chage the puly to get to the numbers you want or something else,and also how do you control at what rpm you get the boost?
238 is at the flywheel - not at the rear wheels :) You loose power through ur drivetrain. All car manufactures always advertise flywheel KW, never RWKW. :)
+TheRealestEver If a part is "over-engineered", it's unlikely to break, even at higher power outputs. But I get what you mean. There's not much room for more power available in these cars before things start breaking.
+TheRealestEver this engine has heat problems if u want more power u have to be very carefiul with coolimg friend works for bmw valves reapir only material for it 4000€
I want to install turbocharged to my Z3 2.8 Roadster 2000. I can't find a dealer or anyone to install and if you have it. What is the cost. And the video. To install ?
Turbos are way harder to install. You have to tap the engine oil pan, replace the exhaust manifold, lay the oil feed and return lines, all the plumbing for the intercooler (turbos need one, not necessary for a centrifugal supercharger) and tuning is much more difficult. It also costs much more. However, you do have the ability to make more power on exhaust driven turbos.
