Neat! Install one of those, and you *might* be able to beat a stock Camry off the line!

lol, i want exhaust driven turbine, but it is garret so my guess is they might actually work extremely well. It is a new tech that is just now starting to be perfected.
The torque amps actually have dyno proven results, but way too expensive for an electric turbo that has major limits.

The 2020 Camry is no joke. HSE is 2.5L 206 hp. May not beat an RX8 but it would keep pace.

Yeah these are interesting...considering the work involved is minimal.
This is more like a nitrous application than a real turbocharger when watch Garret on Cletus use the Torque Amp.
If you’re using it to surprise people on the street with the power then it has a use. Should be fun. They made a shitty cobalt quickish.

that webpage sucks so bad on my iPwn that I could care less about it or ever going back to the Forbes website again. These newspaper and magazine print companies are totally clueless about why they’re heading straight for the bankruptcy gutter.

lol. Just watch Cletus Mcfarland and the Torque amp to get an idea.

I get my news from a site that has all headlines in html for this reason...it is a shame.

I think you missed the joke. One of the things that caused me to facepalm every time I drove my RX-8 is that every Camry and Accord actually would beat me off the line. Even some driven by grandmothers. That application is not exactly where the RX-8 shines.

Not exactly. The new Garrett is dual mode. Electric at low spool, and exhaust driven at medium to high spool. This all but eliminates turbo lag. It would be fairly complex to install.

Im not sure about Garrett, but the Torque Amp is literally plug and play. I would hesitate to install a combo of electrical and exhaust driven turbocharged system. Wait for others to find the problems first...

I like the idea of it but for aftermarket , I think I would prefer the simplicity of a very fast spooling turbo . Some of the results you see over in the RX7 forum with 7670 EFRs are spectacular. An electric setup would not really improve on that much ...IMO

Certainly a simpler and lighter system than twincharge systems that some German companies experimented with, or the sequential turbo system on RX7s. I imagine this becoming popular on small displacement engines for bursts of low-end acceleration. Potentially also in racing as a KERS-like boost feature.

A few benefits, air intake temperature, weight, engine safe(if it doesn't fly apart into your engine), and instant spool. But way to expensive for an electric turbo......

The tech isn't exactly new, it's just only used in more expensive cars at this point.

IMO for econoboxes this isn't really necessary... There isn't that much boost for the lag to really interfere with the driving too much. When you have more boost and a bigger turbo, then lag might make this more necessary.

As for me, I personally trust bigger displacement engine more, and turbocharging is a bit of a cheat in itself due to how rich the engine runs when you floor it. The article seems to suggest that this e-turbo will mitigate this, but I don't see how(or the article didn't do a good job explaining it) since air gets hot as you compress it(turbo, e-turbo, supercharger, doesn't matter) and you need to run a gas engine richer to prevent knock if you want power.

We all know the 8 doesn't have any low-end. I once drove a rental Jetta as my 8 needed some body work done. Great low-end for city driving, but try passing anyone on highway and that's when you will realize the thing only makes 150 BHP.

The 8 is also geared pretty well for the engine.

When I see a battery, the last thing I think of is light-weight.

The amount of energy needed to spool a turbo means it won't be piggy-riding off of your starting battery. Besides, batteries wear out, so that's gonna be additional cost for debatable benefit on a grocery getter.

I have installed Garrett and Borg Warner turbos in several Miatas now. Assuming the turbo is appropriately sized, making them spool quickly is straightforward. Just use 3" intake and exhaust plumbing. The EFRs do spool faster, but both will provide sufficient boost under 2,000 RPM. I imagine many auto manufacturers have issues with packaging that make using that size pipe challenging, so other solutions are required. That appears to be where something like this hybrid electric turbo comes in.

My M235 has a twin scroll turbo setup, and it reaches max torque at only 1300 RPM. Unlike many other systems, it does not run out of breath on the top end. It is a pretty simple setup, too. (Or at least as simple as German engineers are capable of making it.) I am impressed with it so far.

Yeah that's a good point, car turbo tech has moved forward. I wonder if aviation would have use for this, as temporary boost for take off / emergency power. Lugging turbos around gets complicated/expensive/heavy.
