There is no point using an excessively large turbo if you dont plan on using it in its efficiency range. Said another way, you should match the turbo output to your power goals... So dont buy a turbo that can make 1000 HP if you only plan on making 500 cause all you will have is excessive lag and a horrible powerband.
As far as safety on this platform we dont know the limit of this motor.... |

We're also limited to 22 psi IIRC due to the TMAP. |

Im not sure about on the N54, but on other platforms they can use "scaling" to simulate PSI above what the MAP can read. It doesn't really sound safe IMO, but it works from what i've read.

It's also worth mentioning that a 500whp single turbo engine will be far less stressed than a 500whp RB/ASR turbo engine. Not only will it require considerably less boost to make that power, less heat will be retained in the head due to not having a heavy cast iron manifold bolted to the engine (acting like a heat sink).

The graph would look probably look like max torque at 4k+ rpm, all the way flat to redline, and HP will continue to rise from 5.5krpm all the way to 7k rpm if the revs are not adjusted ie: revving to 7.5 k rpm for instance. All speculation though. How strong can they go? i say they need to show a minimum of 550whp or bust. On stage 1 that is, i think stage 2 with the rather small heads/ exhaust ports there might be more hardware upgrades.

I made a signature! w00t
Perhaps I can help him understand a little more: Take your typical passenger car tire at 32 PSI... Now take a tractor trailer tire at 32 PSI... which has more air in the tire? There is more air in the tractor trailer tire at 32 PSI then a passenger tire at 32 PSI. |

He's thinking of the TMAP pressure as if it's a reading from a fixed volume pressurized vessel. If that was the case 16psi=16psi, but thats not whats happening in the manifold.

The bottom line (and what that fgt expensivetaste doesn't grasp) is that boost psi and cfm are two different variables. You can increase cfm without increasing psi. A larger turbo at the same boost as the stock turbo's will have a greater cfm value. More air (cfm) = more power. Period
