Engineering Evolution To Drift Future

So this week Volvo show us the Performance Drive-E the engine 2.0L with 450hp with 3 turbos without lag. I start to reading some articles to try to understand how this system works. Found some articles on Jalopnik and Autoblog if anyone didn't see it yet. So the system works with 2 turbos + a electric turbo what makes the others 2 spooling and this is what cause no lag (i think). First of all im not engineering so i dont understand to much of this so thats why i creat this thread. First of all how a electric turbo works? The ECU controll the electric turbo and make him to spin transferring air to the others 2 and make them spin both at the same time right? Something like a antilag system?
If this system works like that questions continue to emerge so if the 2 turbos always keep spining they gonna generate heat and friction like the antilag so turbos gonna have less lifetime.So this system is only a antilag 2.0.
Other question is can we apply more pressure to this turbos?
All this question is to try to understand if this system gonna work on Future Drift. On the near future can we apply this into a Sr20det or other engine? What is the advantage of this technology on drift?
What you guys think about this?
 
Aside from the supercharger being electronically powered, there's nothing new about it.

Jalopnik and Autoblog and all these other wanky blogs are written by people with fuck all clue, so won't get much joy from them.

Basically, it's a normal 2ltr 4cyl engine. Just like the McLaren P1 using the electric motor to power the wheels for 'torque fill' at low rpm and before the turbos kick in, the electric supercharger on this engine does exactly the same, but instead of directly powering the wheels, it indirectly does giving the engine low rpm airflow it could never have normally.

It runs two conventional turbos, but in the same way as a single but twin scroll turbo- One turbo feeds from 1+4, the other 2+3. This means it spools pretty fast for it's size, just like a twin scroll single turbo will.
Turbo life will be no different to normal, turbos will spool up and down like normal, just faster than normal.

The supercharger is electric, MUCH more powerful than one of those crappy eBay electric superchargers, and could flow around 200-250bhp or air, spool up pretty much instantly, and could run for approx 60sec non stop without charging.
This might not sound like much, but it's purely used for low rpm torque fill, to provide the low rpm boost before the turbos kick in, and to help the turbos spool up. Basically the supercharger can/will give like 300lbft+ at 2000rpm, like a big V8 could. It only being able to run constantly for say 1min without recharge don't matter, as it's unlikely to be on for more than 10sec at once even ragged hard.
Supercharger probably switches off at full boost, and almost deffo is only activated at either 100% throttle or near as damnit.

The supercharger plumbing is simple as it just blows through the compressor inlets, no problem there. The supercharger setup, aside from being electric, is no different from some twincharged engines, like the factory VW 1.4ltr one.

So yes, that setup can be used on ANY engine. In fact very similar engines have already existed in the past, just it's only incredibly recently that electric motors and batteries have become powerful enough and small enough to power a small supercharger for a short time.

Hope this helps.
 
Single Turbo = needs time to charge, than all hell breaks loose. Big lag at low revs. Simple Physics.
The bigger the Turbo, the bigger the lag.

Twin Turbo = two smaller equal Turbos working simultaneously together. smaller lag.

Bi Turbo = small one, little one. the small one charges faster but not in high revs. as the revs build, the big Turbo kicks in. nearly unnoticeable lag after 2000rpm or so.

Triple Turbo. = bi Turbo plus an electronic Turbo that can charge where no mechanical Turbo can charge. Revs build, the small one kicks in, at more rev the bigger one kicks in.


It's no brandnew Volvo thing. Audi "invented" the electric Turbo years ago and BMW has already a triple Turbo Diesel on sale (M550d).

That's total shite to be fair. Makes no sense.

Single turbo vs Twin turbo? You think two 200bhp turbos on a 2ltr engine spools up faster than a single 400bhp one of equal spec, just like that? You think they weigh less? Well they don't.

Bi turbo = What you describe is NOT bi-turbo. Bi turbo is just twin turbo. You describe some odd mix of compound and sequential turbos that makes no real sense. Neither work exactly how you describe.

Triple turbo = Err, that just means 3 turbos. The M550D has 3 conventional turbos, but in sequential AND compound form, not 2 normal and an electric supercharger like this engine.

Audi didn't invent electric turbos either. First electrically assisted turbos were done by Garrett decades ago, but have never made full production, and this setup isn't a turbo, it's an electric supercharger, which Audi didn't invent either, and has also been around for decades, just is only just starting to be a viable thing to use.
 
They are both twincharged yes, do the same basic thing, but the Volvo version is more advanced and would work better.

But it's the same basic concept.
