um, so how is this going to work? exhaust from both sides plumbed into the smaller turbo and then split into the larger two? sounds overly complicated for what is probably a small gain.

Seems to me this is opening up more and more potential problems with the additional complexity. Tuning for smooth power delivery has to be a pain in the rear too. I'd be terrified to buy any of the new tri-turbo setups used in 3-5 years...
Seriously. |

Yeah you guys are probably right...the engineers at Porsche are idiots. What do they know about designing engines?

No one said they were idiots - it seems like a lot of complexity, but if your name is Porsche, there's not a lot you can't do with enough profits...

Not sure what the expected gains are from something like this, or the expected repair intervals... But I'm happy to see more models coming out on the new 911 chassis! Now we need an RS package plz.

The old sequential turbo setup in the FD RX7 wasn't very reliable and this will be much more complex. I'm sure when it's working right the car will be a beast but IMO they will be used cars to avoid.

In defense, my R1's sequential twins are still fully functional without rebuilding or replacing any of the components so far... It's been about 20 years now

Computer and turbo tech has moved forward quite a bit. Like they said, this isn't the first car with 3 turbos.
I think that the increased flexibility in powertrains is basically getting rid of an engine's "character". Most motors had a weak point, either inability to rev, or soft down low, then when you felt the hit of power, it was the fun point of a car. Now with variable timing/turbos/etc there aren't any soft spots to feel power come on. Modern engines are worse by being better. |

We need more information on how the system works. There are a lot of ways to do multiple/sequential turbos. The regular BMW diesels use compound turbos where one flows into the other.
So this isn't going to use an electric compressor of some sort? |

Gonna have a hard time even finding the engine with that many turbos.
alt, compressor, PS pump, compressor, a/c compressor, compressor, turbineturbineturbine, and PIPES EVERYWHERE. |

I think Porsche is innovative in delivering new tech and the 3.8 H6 will need it to stay competitive in the horse power wars.

Oh, all you need to do is wait for the final 2 years of this chassis and you will have every RSR Sport S Targa Cup Spyder version you can imagine

I'm not saying it's going to be a bad engine, just that it will look like the big diesel gensets that have turbos all over them like warts. |

BMWs M division, BMW Gmbh, Porsche and audi will all have tri-turbo set ups in there future line up, 3-5 years later Japanese car makers will follow suit, as always..

OK, first off; you guys suck at jokes. Jeesus.
Second; yes, you can do all kinds of concatenating to make a simple layout. You still need three turbos and the piping between them, the intake, and the exhaust. This is non-negotiable whether the piping is in the form of pipe or a complex casting... Third; I am an engineer, i know how to think like one. |

Here's a dyno graph of a 20+ year old naturally aspirated engine: http://29.media.tumblr.com/tumblr_lj...b5xmo1_500.jpg Ignoring the peak power, notice how the torque only varies a total of 20% from 1500RPM to 7500RPM. [sarcasm]Obviously, it must not be a fun car to drive - having a flat torque giving you punch at any RPM? HA, what were those idiots at BMW thinking when they designed the engine for the McLaren F1...[/sarcasm] And here's one from ford: http://www.blogcdn.com/green.autoblo...t-4-torque.jpg [sarcasm]Again, freaking idiots for designing an engine with power available at any RPM.[/sarcasm] |

I don't know if the Japanese will do this, unless they switch back to inline-sixes. Wouldn't tri-turbos be a nightmare for V-configuarions anyway?

Missed my point. I'm in awe of Porsche and BMW engineering but that really doesn't have a lot to do with reliability and maintenance intervals.
