Thanks to K&N for sponsoring today’s video.Head on over to knfilters.com/donut for special discounts!
What do a $1.8M supercar, a Group-B rally monster, and a tiny, hundred-horsepower hatchback have in common? They’re all twin-charged: They have both a supercharger and a turbo. A true KFC Double Down sandwich of power. And this decades-old design could be making a comeback. On this episode of B2B, we’re gonna figure out why you would double-down on forced induction, and why so few cars have ever been twin-charged. Turns out, mo’ charging might just mean mo’ problems.

Detroit (and I think Cummins) made twin charged engines in the last 30 years. The Detroit had 12L+ of displacement and I believe the force induction system was making like 75lbs of boost. The horse power numbers weren’t particularly impressive, but they produced well north of 1,000ft-lbs of torque

@dillon8987 2 жыл бұрын

Dillon, yes Detroit considered them to be NA, but a Non turbo version still made pressure slightly above ambient, something in the range of 1-2psi. By a technicality that would class it as forced induction,even though the blower is only actually there to force the exhaust gasses out.

after a certain year, BMW caught on to "turbo lag" and decided to have an option on their M vehicles to "pre-spool" their turbo's. Instead of waiting for a certain RPM to get your power, you can put your car into "sport plus" mode and instantly hear the turbos spool up. When you hit it at a red light, you're not losing any low end power.

Twin charging on the other hand has been used quite successfully on many aircraft over the years, and those dudes went nuts pulling every oz of power they could. Back as early as WW2 we had engines producing up to 3000hp give or take, though the engine I have in mind I believe had multistage supercharging instead of being twin charged, but I digress. They also have a fielded a few special kinds of turbochargers implementing a power recovery turbine, that not only spools the compressor but has a shaft connected to the turbine (some may have a second) that inputs additional exhaust gas energy back into the crankshaft.

I remember way back in the early 00s some madlad twincharged an AE86 with a true bypass setup. Once the rpm got high enough that the turbo output more volume than the supercharger could handle, it bypassed the supercharger. I want to say he even setup a clutch mechanism like an A/C compressor to remove the parasitic loss of the supercharger. The plumbing on it was absolutely insane. But the guys powerband graph was like a tabletop.

Thanks for explaining the way the system works. I've wondered and speculated since I got a car that had one in 2019. Speaking of, you forgot one of the major and only brands making twin-charged engines right now; Volvo. Volvo also makes Twin-charged engines for both Semi's (I think a certain D13 model) that produce over 1500 ft-ibs of torque and around 400 hp and for cars their "T6" models past 2016 which are 2.0L Twin-charged engines that produce about 306-330hp with equal amounts of torque. their hybrid "T8" also uses the twin-charged engine and produces a combined 400-415hp as well and around 475ft-ibs of torque. Not going to forget the rare 2015.5 S-V60 Polestar line that used the 2.0L Twin-charged setup to produce about 360+hp also Just before Polestar split into it's own car making. As someone who owned a 2019 Volvo XC90T8 hybrid, I can say the acceleration was absolutely insane and I never experienced any form of turbo-lag. It also got fantastic gas mileage, even when not in hybrid/electric mode. That said, my favorite engine is still the Yamaha 5 cylinder inline Volvo used from 1995-2012ish. Specifically the one in my 2007 S60R which has a 2.5L that produces 300hp and 295 torques. The turbo-lag is quite noticeable though at low RPM, but it's boot threshold is only 1850 RPM, which is nuts.

One set of exhaust valves can be silenced, by moving the cam. All the exhaust drives one turbo bringing it up to speed quicker. When that turbo reaches max volume, the valves are engaged spinning the second turbo. The third compressor is electric used just for throttle tip in.. reported to have less throttle lag than a naturally aspirated engine.. to spin the electric compressor quicker and keep the electric motor smaller the car has a 48 volt system. Wish they could import it to the USA.

@@legocommandercody800 Indeed. Almost all US warplanes of WWII were twin-charged. The blower was built into the engine, usually on the accessory case at the rear and driven by a quill shaft from the crank. The turbo might be anywhere. On the P-47, for example, it was located 18 feet behind the engine. The Thunderbolt was actually designed around the bulky turbo/intercooler arrangement. The main exception to this was the Merlin engine used in the P-51 Mustang. The Merlin was a British-designed V-12 with an excellent two-stage blower and an intercooler between the compressor stages. The Merlin replaced the GM Allison V-12 which had only a single-stage blower. They couldn't fit a turbo into the Mustang's slim fuselage. The US really went all in on turbochargers. Graham White, who wrote a fine book on the R-2800 engine, notes that General Electric built over 250,000 turbos during the war. The device was central to American strategy in the air campaign.

Yes, BMW made a sequential twin turbo on their 335i platform. Smaller turbo for low to mid and a bigger turbo for mid to high. Some companies combined it in one turbo using vein system.

Still some miniscule lag, and a blower is still more efficient, and provides more oompf, at really low rpms. Furthermore, I think that you can increase the turbo size, since you're not restricted by a smaller turbo. Also, who says that you can't put a sequential turbo setup *after* the blower?

Twin scroll turbos are the new standard. There really isn't any reason to be single scroll except cost. Sequential turbos, twin turbos, and twin charged engines are too complicated AND expensive.

Both were always on. How much charge air the turbo generated was varied by a waste gate associated with altitude. The system in the video is sequential, while the p38 (and many American planes during the war) were compounded (it’s referenced as two stages). The turbo would feed compressed air to the centrifugal supercharger further enhancing the boost levels. I would encourage you to check out Greg’s planes and automobiles. He goes into significant detail on these setups.

Dual forced induction is very common on the maritime industry. I used to work on old Detroit Diesel series 71. The 6 71, 71 series 6V, 8V had the blower and turbo. I also worked on a 16V 71 series generator. The engines were two cycle, both blower and turbo were necessary on the engine for air intake and to blow the exhaust out of the combustion chamber. Those engines have an unique oil burn smell. There are some Fairbanks Morse medium speed engines in locomotives and industrial generators that also have blower and turbo system.

On a construction job site that I was working on, about 20 years ago, the place we were working on was going to be a large casino. They had 2 HUGE generator sets that wete to be installed. The gensets each had a 2-stroke V-16 Detroit diesel, that had 4 turbos hanging off the exhaust manifolds, the output of which then fed directly into 2 Roots blowers, which were laying inline across the long intake manifold. The mufflers that were laying on the floor for them were large enough that I could crawl inside the pipe, and darn near stand up inside of it. I still have a picture of that around somewhere. It was QUITE an impressive setup. I imagine that a casino needs a SHITload of electricity if the grid were to go down. I was there the day they were finished being installed, and then fired up and load tested. Them funkers ROARED when they were warmed up and brought up to full load. Being 2-strokes, and 16 cylinders, those things sounded like they were SCREAMING but in reality, being a 3-phase generator, they were most likely only turning 1800 RPMs. I'm guessing that the sound I heard is EXACTLY why they call them, "Screamin' Jimmys"... The "Jimmy" part meaning GMC, who was the manufacturer of the engines.
