Here’s What You Need to Know About Porsche’s New Turbo Flat-Four Engines

From Road & Track:

Unlike the 911, which is using a 3.0 liter flat-six in both the Carrera and Carrera S, just with different turbos, the 718 twins will have a 2.0 or a 2.5 liter turbocharged flat four. The 2.0 in the base cars will have 300 horsepower and 266 lb-ft of torque while the 718 Boxster S will have a 2.5 liter flat-four turbo with 340 horsepower and 295 lb-ft of torque. There could also be a GTS version coming with 365 horsepower.

 

Porsche is going all-in on turbocharging.

In the Facebook comments, I already see people equating the upcoming 718 engines with Subaru EJs.  Now, when has Porsche ever not blazed their own trail?  Porsche will almost certainly ensure this engine will generate glorious (or at least non-nasty) sounds.  Subaru’s trademark sounds are due to the EJs running unequal-length headers.  I highly doubt Porsche will do something stupid like adopt unequal length headers, especially if they opt to use twin-scroll turbochargers.  With luxury-sport cars such as these Porsche variants, they’re going to ensure the car sounds like it looks…fast, powerful, and sleek.

Boxer-powered Motorcycle??

Check this out!  Now, this isn’t the very first Boxer-powered motorcycle…BMW has a crap-ton of them.  Honda’s Goldwings have always used the horizontally-opposed engine configuration, as well.  I like this one, though, because both wheels are powered.  As well, that black engine looks sinister!  I’m not sure if the coloring has been photoshopped to represent WRX/STI rally colors (rally blue with gold wheels…Subaru trademark).

There’s also this:

This IS powered by a WRX engine, but it’s also just an electronic sketch.  Be sure to visit that link, because it has a ton of pictures of the bike and engine…it also has a quick article on how the bike was designed.

Flat Four-cylinder Turbo Porsche Cayman

I posted awhile back that Porsche might be going mainstream with turbocharged flat-four engines.  Boxer engines aren’t the most efficient when it comes to making power, but they do offer outstanding balance (center of gravity, which will enhance handling).

Here’s another article:

The Heart and Soul of Every Subaru — the Boxer Engine

Do you like documentaries on car engines? Here’s one from Subaru of America on their horizontally-opposed engines (aka boxer engines).

I’ve not yet viewed it, but once I have, I’ll update this post with my comments (if any).

To read commentary responses to Subaru of America’s Facebook post, visit here:

4-cylinder Boxster and Cayman Video Footage at NBR??

I just saw the following posted on Facebook:

http://www.roadandtrack.com/car-videos/this-is-probably-the-flat-four-cayman-at-the-nurburgring

I also posted awhile back about the fact that Porsche was considering using the flat-four layout in upcoming engine options for the Boxster and Cayman.

I then saw the videos provided on that page.  First, they posted a baseline video, so that people know how a current Cayman sounds:

Then, they posted a Boxster andCayman with what’s unarguably a flat-four motor:

I prefer the sound of the flat-six, but the flat-four isn’t bad.

EDIT:

There’s quite a bit of uproar with the Porsche “purists” on R&T’s Facebook page…check out the comments:

 

Nice WRX!

I saw the below on the Facebook “STi Photography” group:

 

It was a very good video composition. The car wasn’t bad, either.

Here’s another video (from the same FB group) of an STI playing in the snow. I’ve done something similar but never filmed 3rd person:

Subaru Engine Assembly/Disassembly – Video

If you’re curious as to how Subaru engines are disassembled and assembled, the two videos below are bursting with knowledge and pertain to the EJ257 (STI engine in this case).

What’s cool is that the person in the video is a master Subaru technician. He explains a LOT of things (with the help of the person behind the camera). As well, he explains such terms as cracked ringlands (30 minutes into the assembly video). Ever heard the term “spun a bearing” and don’t know what the term means? He explains that term. He shows what bearings are and shows the differences between forged & cast pistons (and explains the differences between the two). He also shows the damaged caused by driving these cars with no oil.

These are great videos!

Note: I’m having a hard time finding the disassembly video, but will post it here when I find it.
