Russian components, American components ALL MADE IN TIWAN !!!
sorry had to throw in that line from armageddon. I have found precision engineered German cars don't really like unregulated Chinese or Taiwanese parts where the word precision is used loosely at best. Though their getting much better than they used to be i still hear stories of parts grenading in motors causing tons of issues. |

We've all heard stories...I want specifics.

What exactly is the goal here if a tune, DPs, and exhaust will get you near 700hp? I was under the impression the transmission isn't good for much more than that...

Our turbos have a smaller turbine then the S63tu so by putting an even larger compressor you just create more lag with the same limits due to the small turbine. At really high pressure ratios the larger compressor might help but you run into the MAP issues. Not sure how PP performance is getting around it but you cannot get a straight answer out of them or their distributors. For the price of their package I'd just get a F85/86 M since it is the S63tu motor and has a ton of support. A F85/86 M with the full JB4 will crush ours even with turbo upgrades. After a tune and pipes on the E70/71 M you go down the rabbit whole really fast. Not to mention there are people that have had the transmission eat it's self on stock power levels. Not saying it's impossible. Just you need to decide how much you want to sink into it for what you are going to get. That's a call each owner will have to make. |

My tuner said himself that he works around the limits of the stock MAP sensor, so he said for me/us to swap the sensors are useless. At this point I'm taking that information as is.
Seeing some of the cars I've raced, the S63 definitely runs out of breath at the top end, which I'm guessing isn't an issue on the S63TU. PP Performance has taken a page right of the $$Dinan$$ books and simply taken stock BMW parts, marked them up grossly and then claimed them as their own - http://www.xbimmers.com/forums/showthread.php?t=638340 I've got a custom intake, downpipes, stage 2 tune and I'm doing my custom exhaust soon as well. I'm doing meth research as we speak...if anything it's just for it carbon cleaning abilities at this point since my tuner doesn't like and/or wanna tune for meth. I've yet to hear a single story of transmissions failing on these vehicles. Drivelines/draveshafts for us and the M5, all day long, but I'd love to read a thread about failed transmissions for the sake of knowing. Agreed...short of an S63TU swap, I don't know we'll ever reach the S63TU's power levels since they're got different heads, injectors, cams, block, rotating assembly, etc etc as I've verified it on www.realoem.com to kill the curiosity of how similar or dissimilar our S63 is to the S63TU. Other than architecture, we share very little...we don't have MAF's, can't run JB4, etc. We're officially the bastard children before mommy got it right lol.

I have a question, how come the S63Tu unit in the F10/12 M5/6 has to run boost at 1.5 bar (~21.8 PSI) compared to the S63 units in the E70 X5/6 M at 1.2 bar (17.4 PSI) to generate pretty much the same power, 560hp vs. 555hp and exact same torque @501 lb-ft....I know the power and torque curves are slightly different but that's a lot more boost for basically no increase in power.
Maximum Boost Pressure (absolute) 1.5 bar to 1.2 bar Output 560hp to 555hp @ 5,750 – 7,000 to rpm 6,000 rpm Torque 501 lb-ft to 501 lb-ft @ 1,500 – 5,750 rpm to 1,500 – 5,650 rpm I understand that the Tu is far superior but this strikes me as strange...unless "absolute" means that the motor has the potential to generate that much boost but never actually does. |

The S63TU is very underrated and quite often gets the same horsepower to the wheels that we get at the crank. The S63 and S63TU are not nearly as similar as people may think. Do a search on www.realoem.com, very few parts are cross compatible between the X5M's S63 and M5's S63TU...at best we share a similar engine architecture and an ///M badge on the trunk.

what about a Toluene mixture? seems to be better than e85. not able to buy at the pump...so its kinda a pain. but the end result is awesome.
im thinking the meth/washer fluid is a great addition for maintaining power. heat soak is terrible in these things, the intercooler system using the coolant seems simple for a factory system. It would be much better with a second separate independent system. im in Arizona and 120 degree days kinda stink. this truck reminds me of the 99-02 audi s4. there was very limited support, chips/downpipes.... with nothing but back yard home depot engineering there were plenty of us who had the thing from 250hp to over 400.... I am in agreement on one sad issue...the TU is far superior and much more responsive to anything and everything... |

B5 S4's have TONS of support. Look at APR or swapping to RS4 parts. I had a b7 S4 and B7 RS4, you want to talk about no support!!

they have support now.... but in 2001, they had none...chip and downpipes... its was lots of late nights on the phone with piggy (mike)
APR was in an 1/2 empty shopping center shopping center, and was as impressive as a bad stereo shop.... I lived about 75 miles away from them... yes, now EVERYONE makes something for an audi... yes, the B7 doesn't have much yet ... my wife's car is a v10 s6...same motor (90%)as my lambo which makes swapping/testing parts easy I have been really looking at getting an rs7....how did you like yours? did you get ride of it? |

I had a B7 (2007-2008) RS4, not an RS7. I am thinking I might give the X5M to my wife though and get an RS7. I believe that Audi changed the ECU in the RS7 and made it much more difficult to flash. The earlier RS7's can be tuned to crazy amount of power.
I always thought that the V10 from the S6's was a totally different engine. I thought it was 2 5 cylinder engines next to each other. The reason being that the Lambo V-10 was too wide to fit in between the shock towers. Quote:

nope...same different intake, but the block, layout etc are all the same. its made buying parts for the lambo EASY...
AC went, 2700 for a ac compressor. traced it back to an audi part number and then to a VW part number....$300 bucks from local vw dealer, same part. same with a fuel pump when it went. makes it really easy having oil filters and suck on hand also the rs7 is such an awesome car.... I have no need for it, which is really me fighting the desire.... |

I believe M5James and are are both on stage 2+ with downpipes... Is there a benefit to swapping our OEM turbos to Pure Turbos? We need more information on them. |

I was under the impression that we can't get much more power out of our cars after tune and Downpipes because the fuel system becomes the limiting factor and no one makes upgraded components.
Has anyone tried the exhaust manifold from the S63Tu? |

http://www.xbimmers.com/forums/showt...ht=DINAN+PAGES http://www.xbimmers.com/forums/showt...ht=header+swap As best as I know, there's a handful of S63TU engines that have been blown from pushing high HP (likely tuning issues), but I don't know of any S63 from being pushed to a breaking point yet. This is by no means concrete, but this is my guess of which order mods will/have been done by most: 1) Carbon filter delete and/or drop in filters 2) Stage 1 tune 3) Stage 2 tune 4) Catless downpipes (tune needed to turn off CEL light) 5) Muffler (be it deletion, purchasing something manufactured or custom) 6) Pure Stage 1 turbos (bolts to stock S63 headers) 7) M5 headers and turbos (mind you M5 guys are swapping to Pure Stage 1 (pushing past 1000hp) and now Stage 2 is in testing) I only know of 2 custom intakes for the X5M, Solo and myself: http://www.xbimmers.com/forums/showt...=intake+feeler Since we can't use the Burger Motorsports JB4 or BCM to control meth, wastegate control, etc. it seems meth is a step that is still unexplored territory as far as I know as well...I'm looking into it for it's cleaning abilities first and foremost, then whatever added octane may be gained for safety reasons, but once again I haven't seen anyone running meth on the S63 yet. http://www.xbimmers.com/forums/showt...php?p=20141649 Poing being...only a handful of S63's are running M5 headers/turbos and/or Pure Stage 1 turbos, so it seems the limits haven't been found because the S63 hasn't been pushed as much as the S63TU. The million dollar question is if anyones bought these wheels.
