Subaru says they cant fit a turbo in the BRZ?
 
http://finance.yahoo.com/news/subaru...182551874.html

"Surprisingly, Hirakawa admitted that STI is developing a more powerful version of the BRZ, a slow-selling coupe that’s also sold as the Scion FR-S. While Subaru can’t equip the BRZ with a regular, exhaust-driven turbocharger due to space constraints, the automaker’s engineers are looking at fitting the four-cylinder engine with a state-of-the-art electric turbocharger that’s a lot more compact. The technology is under study, but it hasn’t been given the green light for production yet."

I find this hilarious...since so many folk have crammed superchargers, big turbos, little turbos with manageable heat build up.

What do you all think of electric turbo'd BRZs?

Doesn't the electric turbo require a large battery to power or? This would be taking a lot more space compared to a regular turbo.

Love them. On e85 mine put down 233 WHP & 207 WTQ about a month back. Actually it's Electric Supercharged though (Turbos are exhaust gas driven).

Nope, fits in the stock battery tray just fine thank you.

Well, if it truly is an electric turbo, it would be powered by an exhaust driven generator turbine which may charge a bank of super capacitors. This would be an amazing breakthrough if they could make the technology work at a mass market level.

You could but usually you have a big alternator to charge 2 batteries 1 for the car and 1 for the turbo, alternately (pun intended) they could have a single battery and have a voltage cutoff for the turbo so it does not impact other vehicle systems. The turbo would run as long as it has power. So its great for daily driving and light track use. But it does not have to multiple/rapid heavy use sustain that conventional turbos do.

What they do have is really fast spooling rates...which (if mapped right) would give you 100% pressure at take off.

The Phantom system uses the stock alternator which is rated at 130 Amps. More than enough to recharge the batteries quickly.

The batteries are separated into 2 discreet systems.
1.Compact starter battery for the vehicle and it's systems (Odyseey PC680) 12v.

2. 2x Big Crank EXT16 12v batteries ran in series to get above 24volts (this powers the compressor).
The compressor can give 100% boost at ~0 RPM but it's actually spooled up more slowly for driveability (otherwise the rear end would instantly break loose). Max torque is made available at 3376 engine RPM.

"Subaru has to date ruled out a turbocharged version of the sportscar because of turbo, intercooler and plumbing packaging and crash test incompatibilities."

Sounds like more the matter of it not passing crash tests to Subaru standards, rather than just not being able to fit it at all.

From the article:

Speaking to Australian website Motoring....
That should be all you need to know.

Edit: here's what they're citing: http://www.motoring.com.au/news/2015...ng-board-54765

I still don't believe them.

"...Subaru has to date ruled out a turbocharged version of the sportscar because of turbo, intercooler and plumbing packaging and crash test incompatibilities. "

This may be a true statement. I would like them to say more about the issue. I'm pretty sure that top mount scenario won't work but maybe in the AVO position?

A low output (6psi or less) electric supercharger doesn't require an intercooler, or lots of extra exhaust plumbing. Crash certifying a similar setup to the Phantom ESC in my car would be cake.

Op did you read the article at all???

Second sentence: "Speaking to Australian website Motoring" lost me there bullshit radar overload explosion imminent.:bonk:

Again moroting.au so it's all made up from someone's imagination.:laughabove:

I'm not disputing that Motoring.au is terrible, but to be fair, they are quoting Yoshio Hirakawa directly through much of the article. This specific line isn't though, so who knows. It is believable though, and I'm pretty sure nobody on this forum is qualified to say otherwise, so I'll file that one under my personal list of plausible reasons we don't have a BRZ STi.

"Sometimes my farts smell like popcorn," said FT86 Club forum member Luftwaffle.

Given motoring.au's reputation, they could have done exactly as I just did.

As far as not meeting crash test regulations, I can believe it.
