Truth be told, AMS is not 10 minutes from me and I thought with all the discussion lately I'd stop by their place last week. As it turned out, I couldn't get there until Friday at almost 5:00 and they were wrapping up for the day - but still were perfectly willing to chat for a few minutes and offer up a complete tour of the facility on a day when there was more time. Not a fly-by-night operation by any stretch. Like Brick and Mortar real deal in my opinion. Kudos to AMS for pushing the envelope. |

With the bigger turbos.. gonna have to run much wider tires..otherwise it's going to be a mess !!

Getting better! Martin is hard at work trying to maximize things while keeping everything happy Blue line is stock, red line is the latest tune...all on 93 octane. We have to take a break for a bit as Martin needs to get to Florida for the 1/2 mile event with our 2000+ whp GT-R but he is going to jump right back on this when he gets back. Eric |

So why can't we use meth for that ?

I think he's answered this a few times now -
1. Meth isn't a safe way to just pile on more boost, even if you can. You can of course do it, if your turbos have the capacity, but it's not safe or reliable. 2. The turbos have no boost left in them at all at these power levels. Turbos don't just magically blow as much boost as you want...they have a limit due to the housing, the shape of the turbine, the shape of the outlet, etc. The stock ones seem to be tapped out around here. You could throw all the meth you'd like at it, you're not really getting anymore power out of the stock units. |

If you look at the last dyno chart above vs their initial one on page1, you will see about a 40whp increase at 6700rpm as well as most of the upper range where full throttle runs will benefit. If they could smooth it out a little more all the way to redline, there may not be an urgent need on pump for upgraded turbos at this boost pressure for us powerfreaks
Ams, can we get a psi:rpm chart? |

Racegas is just a higher octane fuel that still uses the fuelling system the DME controls. Meaning that all fail safe systems are in place if some component should fail. Just like as when you run on street fuel. With meth you introduce a separate fuelling system the DME doesn't control. If that fails there are no fail safe systems in the DME to activate to save the engine. Engine failure is more likely when you introduce that kind of thing. The same with NOS as well I guess. Many use it and with good results and reliability, but if the NOS system fails the consequences can be catastrophic... I can understand why a tuner doesn't want to run that risk by offering a meth option out of the doors. |

Great progress - it's area under the torque curve that will translate to acceleration. If that torque drop up top can be eliminated (larger turbos probably), this car will be a beast!
Anything over 550 in the 3K range is too much and not fun to drive in this RWD setup on stock rubber. |

Maybe this has been asked in the last seven pages but now that we're about to breach 700wtq/hp and upgraded turbos are in play... How is the STOCK trans/ internals handling this level of power... One thing to be in the 600s with it pulling power at the limiter, another thing now that the cat is out of the proverbial bag tuning wise.

I have been running the Leib tune with 647 rwhp (750 crank) and 935Nm without any issues for months. However I have the feeling that a lot more torque will give issues with the clutch slipping and the tranny. I also wonder how driveable the car will be with more power. We are at the limit of what a rear wheel drive car can put down. For a M5 with over 800 crank and 950Nm we will be needing hardware modifications, perhaps even on the engine.
