How Twinchargers Work: Supercharger + Turbocharger

What is a twincharger? How does twincharging work? Twincharged engines incorporate both a turbocharger and a supercharger. The supercharger helps create boost at low RPM, while the turbocharger provides boost at high rpm. It's the best of both worlds, the benefit of low RPM boost and high RPM efficiency.

NEW VIDEO EVERY WEDNESDAY!

[JasonLambek]

This vid was posted ~5+ years ago and I've been wondering about this very topic for even longer.
Thanks for this

[Salachomp]

After watching all of your videos on turbocharging/supercharging, variable geometry turbos seem like the best method of forced induction to me. And thanks a lot for all the videos! (aspiring automotive engineer here)

[DestDroid]

I know this one! Supercharger + Turbocharger = Erection!

[shahrukhmechanical]

You make life so easy, thank you. (y)

[bjh]

I just Googled this topic because the T6 engine in my Volvo uses both and includes the Polestar Engineered mode. Thank you for explaining the interaction and benefits so clearly.

[MJ-upnw]

Ok but can we talk about how Hector is going to be running 3 Honda Civics with spoon engines. And on top of that, he just went into Harry's, and he ordered 3 T66 turbos, with NOS. And a Motec exhaust

[rebjon]

I imagine it must be difficult to tune an engine with both a supercharger and a turbo. Years ago I know it was thought to be impossible, but these days more and more people seem to have perfected it

[alzmi]

I actually seen someone who did it to his Ford GT, but then when be dynoed his car I notice supercharger "Whine" then turbo, so basically from what I understand of this idea is you will never have turbo lag or lose throttle response, to be honest it sounds like a lot of work but it would be sick setup because you will not lose boost because "supercharger belt" might rip at high boost or get damaged,

P.S: great job and subbed

[CakePC_Jake]

Your videos are very informative, easy to follow and enjoyable to watch. Thank you for the knowledge :)

[markjmaxwell]

From my understanding of forced induction.
I used to work for one of the first companies in Australia to cast turbo housings.
The twin scroll is hard to beat for simplicity and cost effectiveness.
Of course with engines in a V configuration twin turbo installations are hard to beat.
I was suprised that belt driven impeller type superchargers never took off in the OEM market.

[chrissmith]

So I appreciate the time u spent to help everyone that's watched this

[edwardglen]

Your videos are well structured and you explain really well. Thank you

[daskurka]

Just came here 9 years late to understand my volvo T6 engine. Great video!

[dhivahari]

Bro, I always think which is better but you just teach me that both will be at the best if both are combined. Thanks bro

[zacjohnson]

Turbochargers are not as reliable as superchargers (not trying to trigger anyone). Its a true fact, Even though superchargers burn more fuel.



i should have put this comment on the turbochargers vs supercharges video...

[robertopena]

Im 17 and got my first truck a 1998 Chevy Silverado with a V8 motor 3 day ago and I've been watching videos like this because I really don't know about cars and trucks. I feel like this video really help I'm making my decision on whether to put a supercharger or turbocharger on my truck thanks

[michaelbudlong]

Could you add a twin turbo with a supercharger? If so would it make none, some or a lot of power?

[andrevorster]

Thanks,

This explained the combination the best. We are getting the Volvo XC60 T6 which runs off this method.

Oh my ... I love this stuff! Registercharging, Dual charger, twostage turbo, ...

... and all the nice things we can do when this is further made more complex, miller cycle always comes to my mind (because it is the logic net step after downsizing and optimization of detailery and stuff), hybrid also, and those two, with a halfway-complex, halfway-efficiently used boosting/recovery-system, with an electrically pampered ICE, the improvements in efficiency that are literally lying in front of our feet are only exceeded in their impressivity by no one really going all the way.

All the cool things that came into greater series production have been lying in drawers since close to forever. Stratified injection? Old, thirties! Variable valvelift and duration? Twenties! Turbochargers with, say, variable compressors? At least 20 years old. Electrically assisted turbochargers? Were "the next big thing to come!" ever since downsizing became the industrie's standard.

Anyway - I love your videos, because, it seems, you are a great narrator and know your stuff. I haven't heard anything that was wrong so far, nothing that was harder to understand than it needed to be.

I must admit, I sometimes chose 1.25 speed at youtube, I would actually like you to talk a little bit faster ... but then, again, who am I to demand anything?

... one of my favourite channels - keep doing this, stay true to yourself and ... and uh have a nice day?

Yeah. It in fact IS a nice day.

A number of piston airplane engines used in the 1940s and 50s have both a blower and a turbo. However the turbo is normally used for cruising at high altitudes, 15, 000ft or higher. It’s only used at altitudes below 10, 000ft for depressurization of the cabin prior to landing.
