    This Audi RS7 we have seen in action before going up against a tuned BMW F82 M4 where it performed very much like a stock RS7. The tuner VAG-Doctor (no gynecologist jokes please) must have actually done some work to the RS7 this time as it does much better going up against a PP-Performance tuned Porsche 991 Turbo. The RS7 loses against the 991 Turbo but it puts up a strong fight this time with faster trap speeds. In the 1/4 mile the RS7 goes 10.9 @ 128.48 which is exactly the range for a tuned RS7. The Porsche 991 Turbo goes 10.40 @ 132.32 which is about the same we saw out of this same car previously against an Aventador. The second race has the 991 Turbo square off against a tuned CLS63 AMG 4MAtic with its M57 tuned by Ramon Performance whoever they are. The 991 Turbo catches the CLS63 sleeping at the line and gets a nice jump. The CLS63 has no chance to catch up and loses the kilometer drag race. At the 1/4 mile marker the 991 Turbo manages a 10.314 @ 133.42 to the CLS63 10.962 @ 129.823. The kilometer figures for the 991 Turbo is 18.982 @ 172.07 to the CLS63 19.753 @ 149.328 as the owner clearly let off. It's too bad the CLS63 and the RS7 did not go at it as they are more evenly matched.

    Haven't heard of this one? Details? I'm sure they figured it out but you raise an interesting point about the head gasket.

    Damn, that's a shame. Car had so much more potential! But at least the platform is still progressing. Can't wait to see how the Sound Performance (I think it's fixed now?), MaxPSI and FSR Motorsports turbo cars do the rest of this year. Does anyone know if the head lift issues above 800whp+ have been resolved? All of those threads died out... I'm guessing so (if Kenton's car is rolling around at 900+), but I'd like to know if they ever figured out what caused it and what they did to fix it. No one that I've read about seems to have tried an MLS or cooper ring head gasket in the states yet? Seems to work well for the Scandinavians.

    The internet is clearly bored when this garbage is getting front page press on every automotive website. Autocar is generating hits the best way they know how which is by click baiting with speculation. It's based on comments from BMW M head Frank Van Meel so at least they didn't just make it all up. The Japanese once tried a horsepower cap. It didn't work. What it did was hold them back. We can guarantee if Mercedes and Audi are stomping BMW in output then BMW is going to lose their enthusiast core and M cars will no longer be viable. This is more true now than ever with M cars basically becoming dragsters. A 600 horsepower cap is just as meaningless as Van Meel's statement, “For now, 600bhp is the most you can get in an M car." BMW is already offering over 600 horsepower anyway if you go by the real output at the wheels. His statement seems to be saying 600 horsepower is the most you can get right now, as in today, which is true. If BMW only offers 600 horsepower for the next generation M5 that likely means closer to 600 at the wheels. The new BMW M3/M4 are rated at 425 horsepower which on paper is very close to the 414 the E9X M3 offered. The reality is that the new M3 and M4 are much more powerful than implied. This manual transmission being eliminated statement at least has some basis in reality but it's a topic that comes up every year. The F10 M5 was reported to ditch the manual and it didn't. The F80 M3 was supposed to ditch the manual and it didn't. Van Meel has a point that the DCT outsells the manual and Porsche of course learned this lesson and only offers the driver oriented GT3 in PDK for this reason. BMW M's head of engineering stated the M3 would always have a manual. The manual is definitely dying but do not write it off completely just yet. We would expect the next generation M5 to likely not have a manual but there is room for a manual transmission in the BMW lineup as long as enthusiasts continue to demand one. Let us all not forget how badly Autoblog messed this up. Van Meel understands this, "It’s difficult to say we’ll stick to the manual, but we still have a big fan community for manuals and we are not going to take away something the customer wants to have.” The main conclusion is that Autocar's article is garbage. BMW will offer more than 600 horsepower as they already do. The limit is not in the motor but in putting that power to the ground. Expect all wheel drive on the next generation M5 for this reason. Great click baiting by Autocar. Well done. Now if they could only put as much effort into real news and reporting. Source

    Be forewarned, there is a bit of tuner politics going on here. That said, recently something caught our eye and also caught a few tuners eyes. BenzBoost received an e-mail from MTB Germany regarding their Stage I tuned for the Mercedes W205 C63 AMG M177 engine. A day later, Rebellion Automotive sent us a very similar graph offering a similar product with the dyno graph in German. To us, it looked like MTB and Rebellion releasing their products at the same was more than a coincidence as was the same style of dyno graph betwen the two with both being in German. This is the not the first time we have seen this. Why would a UK tuner be promoting with German graphs unless their source was German? This type of thing happens often where tuners who are not vendors send us products hoping we feature them. Usually we dismiss these but BenzBoost is interested in making friends and promoting products so our users are aware of their options even if they are from non-supporting vendors. This is why you read articles on products and achievements not just from the people who pay to advertise. It is also why we were glad to show more options on a new platform like the AMG M177 motor. Something interesting happened after the articles went up. More than once source saw these MTB and Rebellion articles and mentioned Rebellion was sourcing from MTB Germany. BenzBoost asked Rebellion about this and they said they do all their work in house. BenzBoost also asked Rebellion if their tune was a piggyback like the MTB tune but was told it is a flash. BenzBoost asked for a flash vs. piggyback overlay from Rebellion but did not receive it. One of the tuners to notice all this was Renntech who said they prefer to stay out of these things but since Rebellion was implying behind the scenes to supply their M133 piggyback box (Renntech since released a flash tune) that they had to set the record straight. Interesting, especially considering you can see Rebellion marketing the MTB dyno bay under their name: Renntech definitely did not like the implication that Rebellion is supplying them especially when Rebellion is the one that looks to be supplied and is reselling: Striking similarity between those boxes and graphs that MTB and Rebellion post. We asked MTB directly if they supply Rebellion. They did not confirm it but they did not deny it: Rebellion denied it: "The reason the dyno is in german is because our physical delivery vehicle isnt arriving until first week in July. We had to go to Germany to work on a Clients vehicle which was one of the first delivered. ... In the UK there is only around 10cars total so far! I have a team of coders on my payroll experts in various fields.. Not other companies.." Now, Renntech alleges the V2 Rebellion box released in April 2014 copies the Renntech design: "Again: they just found out where we got our wiring and hardware from… Still these are NOT the same boxes, even if they use the same connectors. We have a different hardware + a different program that we have programmed by ourselves. In the end we will not get future units from the same supplier to avoid these problems in the future." So Renntech is changing suppliers to avoid potential copy cats naturally. Renntech is using TTE for their M133 turbo upgrade because TTE already began doing the work so it is logical to use them as a supplier. Rebellion also uses TTE as do many other companies. Building turbos is what TTE (The Turbo Engineers) in Germany does. Renntech waited until they had full control of the ECU before venturing into the turbo upgrade. Rebellion automotive did not. Renntech Regarding the M133 Turbo: "We played with an upgraded turbo from the beginning (September 2013) but since the results were not better to start with compared to Stock turbo and Box, we decided to wait until we have full ECU access. Meanwhile MTB sent a unit over to TTE (the turbo engineers) https://www.facebook.com/MTBFahrzeugtechnik/photos/a.144749192238163.25327.140054956040920/610506145662463/?type=1 They also didn’t get much better results but still… The TTE unit was “born” and available from then on, this is why we decided NOT to go our own way with the Turbo upgrade but just to buy the TTE unit as well. The truth is as well, that Rebellion never had whatsoever “development” work on anything. I am sure TTE will confirm that the even didn’t know a firm called Rebellion existed until February/March 2014." Now of course there are politics at work here. Rebellion did not directly state they supply Renntech but implied it: "2015 22:00:46: Matt - Rebellion: You know where the renntech turbo comes from right? 07/06/2015 22:01:16: LondonViking: Same as where you got yours TTE 07/06/2015 22:02:57: Matt - Rebellion: You know who developed the turbo for the A45 with TTE back in October 2013? 07/06/2015 22:03:11: Matt - Rebellion: And has been updating the range with TTE 07/06/2015 22:04:00: LondonViking: I know what your answer will be but and ? 07/06/2015 22:04:21: Matt - Rebellion: Yes it was us 07/06/2015 22:04:43: Matt - Rebellion: And the question why the renntech box is very very similar to ours.. 07/06/2015 22:04:55: Matt - Rebellion: I promise you we are not a guess work company 07/06/2015 22:05:20: Matt - Rebellion: We are a development company and we push the boundaries to a brief 07/06/2015 22:05:36: Matt - Rebellion: Fir most of our customers they want fast road cars 07/06/2015 22:05:53: Matt - Rebellion: For* 07/06/2015 22:24:29: LondonViking: Sorry for the late reply but if you claim their box is a replicate of yours that's interesting 07/06/2015 22:27:49: Matt - Rebellion: I'm not claiming anything �� 07/06/2015 22:28:56: LondonViking: Aren't you saying between the lines they've copied your stage I box ? 07/06/2015 22:31:34: Matt - Rebellion: Not at all. I'm still slightly confused as to why the group insist we have not provide info when we have provided more than anyone else" This certainly is interesting. The truth is probably that Rebellion has a German source and the logical conclusion is that the source is MTB based on the evidence provided although we can not say this with 100% certainty as neither MTB or Rebellion will confirm it. Renntech does not like the implication that the Rebellion box and the Renntech box are similar due to Rebellion's work and is switching suppliers as they believe Rebellion sourced the same supplier as Renntech in a move to copy. You can decide on your own what the truth is.

    I am willing to bet you would not be able to distinguish a difference in the before and after temperature from the noise in the data. It already looks to be a "cold air" style intake. How much heat can transfer through that plastic to the many CFM flowing through those housing at WOT? The fact the housing get so hot hints to me that heat is not being transferred to the air inside. The most interesting part to me is the puzzle you'd have to solve to put those pre-cut piece on the air boxes.

    In all honesty, they likely continued the push for twins because they give you a bigger punch sooner with hp being equal. In non M cars, actual performance is likely less of a concern to today's BMW than perception, and getting pushed back in your seat right away has the perception of more power than being pushed back later by a better performing single.

    I think it was for fitment purposes especially with the way BMW tilts the motor in engine bay. It makes it difficult to fit a larger single capable of pumping out the power the 2 smaller twins can produce. Either way we won't truly know until people start putting on single turbos that match the power rating for the twins. I would love to see a twin 6258 or 6758 efr setup but I doubt it'll fit

    Ok sticky if you say so. They just happened to keep the Twin power plant in all their perfornance offerings, yet put the N55 in EVERYTHING, including SUV's. You want me to believe the N54 is cheaper than a motor they put in basically every vehicle they make. As I said before Twins > Single

    Nahhhhh...German over-engineering. If they put twice the parts on it, they can charge you twice as much for replacements because we all know their parts will fail by design. Lol

    Well with the V8's this is rather obvious. They aren't going to do a single turbo there. The N54 at this point was the cheaper and more cost effective choice. I don't think that's it. If the M2 has the N55 that kind of shoots your hole argument in the foot. I think it's a question of engine supply, tuning, and cost. M cars obviously should have the best. I think the S55 is better the way it is than with a larger single if anyone actually cares about spool or engine response over peak horsepower these days. Alpina can do stuff like that as they are BMW Jr.

    Its not just the S55. Just about any performance offering BMW kept the twin turbo power plant. 1M with an N55 nah, N54. 335is N55? Nah, N54. Z4 N55, nah N54. Pretty obvious that BMW correctly associates performance with the twin turbo motor. I mean shit Alpina went through the trouble of putting twins on the N55. Twins > Single

    This is an interesting question. I think it's because of the spool and response of the smaller twins versus the larger single. Perhaps a larger single would also complicate fitment but I don't know. The M motor will see more scrutiny and definitely people nitpicking the response vs. the previous generation.

    Actual real world results on mutiple platforms over many years show different. Its always more of a hassle to install twins, but they ALWAYS perform better. Why do you think BMW went back twins for the S55? Because they wanted to spend more money on new parts? We have our 950WHP Stage 3 kit showing similar spool to 700-800WHP single kits. They are more complicated, but twins if you can fit them are always more efficient.

    99% sure that turbo is going on a Subi. It looks like its attach to a Subaru up pipe. I still think a properly size single will out spool a twin setup. Its just not cost effective considering how cheap the stock frames are. However if Jake and the gang could figure out the o2 sensor thing I think a vband EFR7163 welded to a n55 manifold would spool stupidly fast.

    TTE (The Turbo Engineers) Germany does some very cool stuff including C6 RS6 V10 twin turbo upgrades. Unfortunately, the US market did not receive the monster twin turbo V10 C6 generation RS6 which is certainly a downer considering the 'US hates wagon' excuse can not be applied as the car was also produced as a sedan. That is water under the bridge. Despite the US market not getting the car we still like to see what it is capable of and it certainly is capable of a ton of power and torque as the dyno results below reinforce. These are hybrid turbos and completely plug and play. TTE takes the OEM setup and gives the turbos larger forged billet compressor wheels and new intake pipes. The result is turbos capable of over 900 crank horsepower and 867 lb-ft of torque: The dyno states the output is 901.4 horsepower in 'normal' output. Below the 'engine output' is 951.8 horsepower. What the difference between normal and engine is we are not sure. Wheel output is below the two of these at 767.6 horsepower to all four wheels. We would love to see it on a Dynojet but these are impressive numbers. Take a look at the acceleration from a standstill to 150 miles per hour: Further details on this turbo upgrade can be found here. Too bad people in the USA can't play with it: TTE850+ Performance Upgrade Turbochargers RS6 C6 V10 The RS6 C6 with its 5.0 V10 Bi-Turbo engine and 580 PS is the most powerful Audi series production engine to date. Our TTE850+ turbochargers will push the V10 to beyond 850PS with ease. Some tuners like KSF Motorsport and MRC Tuning have seen results at over 900PS+ making these hybrid RS6 upgrade turbochargers the biggest maybe available anywhere, yet still totally Plug & Play. Power level reserved only for true hyper cars and still remaining perfect for driving to go get your family shopping, not loosing any drivability. Engineered & Enhanced The formula to making a TTE850+ starts with a much larger forged milled billet compressor wheel, chosen because is highly efficient, new generation type with ultra thin blades, creating extremely high flow for comparative size, giving a compressor map that's very wide. TTE850+ Yield a maximum air flow rate of 615litres a second Vs stock of 500 (estimated). The intake pipes included with this upgrade has been CNC milled and hand finished to match and smooth the transition to the larger compressor inlet opening to lower turbulence and maximise velocity. We also give the stock turbines a special curved clip, a grinding process to the turbine blade tips, curved to alleviate stress from process and clipping the length reduces blade area, thus increasing gas flow and so reducing back pressure, lowering exhaust gas temperatures, allowing safer higher boost level's. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing rotational mass improving moment of inertia. Dyno's have shown no little to no loss in response vs stock yet huge gains in power and torque. Significant attention is given to port the exhaust runners at the flange to match and smooth the transition from head to exhaust runner for maximum gas speed and so improving efficiency to the turbine. Firstly by CNC then hand finished. Actuators used are uprated sprung OE units fitted with our reinforced clamps for trouble free operation. These also can also be modified/set to customer needs and specifications. Equilibrium Precisely balancing our turbochargers is a key critical factor for longevity and performance. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers with this regard. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced yet again but this time at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Supplied with a balance test result document. Key Points Genuine IHI Housings & Components CNC Optimized Intake Pipes included Highly Efficient Next Gen Billet Compressor Geometry Optimized Compressor Cover Machining Clearances CNC Port Matched Exhaust Runners Special Curved Clipped Turbines Genuine IHI Uprated & Reinforced Synchronized actuators Dynamically Balanced & Supplied with test result document Fitment As Original. Plug & Play 850+ PS Capable Designed, Machined & Built by TTE in Germany We offer brand new or exchange (depending on stock). We also can offer to upgrade your used turbochargers Brand New Price 7890.00 euro inc vat To Recondition and upgraded a used set of RS6 V10 to TTE850+ Spec, Price is 2799.00 Euro inc vat Shipping does vary but 50.00 euro is a good guide for Europe wide. Reconditioning price shown is based on overhauling and reconditioning, upgrading a undamaged used turbochargers within specification.

    Atleast they don't try to sell a redesigned intake for $3000 like others, with MINIMAL gains.. I would love to see this with some K&N drop-in filters! These intakes get really hot, even if you drive slowly, when doing highway pulls you can almost burn your fingers if touching them when going in for gas - I learned the hard way :facepalm

    Rumors are swirling regarding the Giulia coming to the USA and namely the high performance Quadrifoglio variant. A quick visit to the AlfaRomeoUSA.com website shows the US branch promoting the Giulia Qaudrifoglio so they seem to be teasing it for the US market and gauging feedback. We did of course contact FCA (Fiat Chrysler Automobiles) and received a response regarding its US sales that did not confirm or deny anything. Basically a meaningless response with no substance. There is no official confirmation but all signs currently point toward Alfa Romeo bringing this car to the USA as a 2017 model year vehicle. Alfa Romeo frankly needs the US market to reach its ambitious sales goals. Watch the video below which will make you certainly hope they do bring it over:
