    Hey everyone! Extremely excited to post a little more data on what we're doing over at Vargas Performance Group. We're testing a prototype hpfp system, and simultaneously testing control over it. Our testing started with normal E85, then Tony switched to E98 to really put the fueling system through its paces. Disclaimers/Info: -"proof of concept" prototype hpfp system -prototype is called "the prototype" because it's not ready for production, meaning we have significant work to do in order to turn this into a product ready to sell, if ever -indicates that DI only 600+ whp is possible on stock injectors -stopped log at 6300 due to auto transmission (have other logs revving higher, fuel pressure & A/F is still good but those weren't the glorious dyno this is) -Rail pressure was much smoother when we used higher targets, there is some control system learning that occurs -this dyno was done with no learning Run Data: Boost: ~28 psi Timing: ~9* Fuel: E98 Low Pressure Fuel Pump: Fuel-it! Stg 3 High Pressure Fuel System: Prototype Port Injection: None Methanol Injection: None Future Plans: -More DI only testing and prototype development -Examination of feasibility for production type configuration/implementation Take Home: -There is room to run over 600 whp direct injection only -Injectors and injector window is not an issue yet -Vargas continues to innovate and push hard

    You will find that after a certain point the majority of high power N54 builds utilize supplemental injection. In the early days it was methanol and these days a port fuel injection system is more common. Either way, it is easy to max out the factory direct injection fuel system at higher power levels especially if running E85. The details from VPG on their 654 whp run using the direct injection system are below: Hey everyone! Extremely excited to post a little more data on what we're doing over at Vargas Performance Group.

    Is 800 rwhp the new 700 rwhp? Just the other day a 737 rear wheel horsepower stock internal N54 was posted on BimmerBoost. Well, this E90 335i takes things a bit further 802 rear wheel horsepower at 33 psi of boost with E70 fuel on a 131,000 mile stock internal N54. Impressive, right? Here is the full mod list: 131,000 mile stock engine car.

It's not going to last forever obviously and running it at 800 plus all the time is asking for trouble but 800 whp certainly can be done on the stock internals even with a well used N54. Great work by everyone involved.

    Well guys I am having fun working with the N54 platform and as some of you know the single turbo kits is not my main business as I have a whole other side of business dealing with many differeent plattforms. The N54 was just my foot in the door in the BMW market so I am glad everyone is liking what my company has to bring to this market with our experience and resources. So, I would like to share some news with you guys.... First up some changes to the turbo kits. I've been getting a lot of concerns on some areas of the kit so I took the time to add a couple things. I have finally been able to design and produce a bunch of these coolant tank relocation brackets. I will be including the brackets with the kits from here on out. And for the guys that have already purchased the kits please contact me and I will make sure you get one. I may just ask for postage on them so just a couple bucks. They will not include the titanium hardware like in the pictures but can be bought for a few bucks. Starting 7/1/16 we will be including a PNP MAC solenoid with our kits. We will also be offering them on our website for $50 free shipping in the US. We have also been getting concerns about our silicone vacuum lines that are used for boost control. The concern is about how the hoses are not able to handle the heat. Well, there is no problem because the wastegates are mounted low and completely away from all the heat generated from the manifold. I spent a good amount of time making sure they were mounted in a position where there was no chance the lines and/or the diaphragm in the wastegates will get burnt up causing an engine failure. The diaphragms in the wastegates are not made of metal, they can melt over time and is why I made sure they were mounted in a cool place. The DOC Race intake manifold with integrated port injection has finally been installed with some positive feedback so far. I have made two. One was installed on VTT shop car and from what Tony is saying it makes the roughly the same power but with less boost. That is better than losing power I guess. We didn't really get into how much power it was making. The second manifold was installed on our shop car. I did a baseline run before we took the factory manifold out last week and we are going back on the dyno this week with the new intake. No changes other than the manifold and piping going to it. Still running AD-Engineering tune with the Haltech they supplied with their port injection kit. Car started up and idles the exact same (perfect), no hiccups. Here are some pics of it manifold and of it installed. Ported head time for shop car! Just stopped by my friend’s shop to check up on the head I dropped off for him and saw what we had been working on. All I have is just a pic to show for now. More info on this later

    Doc Race made waves with their BMW N54 single turbo kit released early this year. The N54 community reception was positive and thus far there is nothing but praise for the product. Doc Race is expanding their N54 offering which will included ported headwork and an upgraded intake manifold. Dyno results and specifications for the ported N54 head will come. For now, there are more concrete details on the intake manifold. This is more of a modification for someone already pushing high numbers and looking for a stronger and more efficient piece. They did get it on the dyno and it is more efficient than the factory design: Certainly great news and an exciting time in the N54 tuning world especially for guys pushing the limits.

    So I am going to get ready to pull my motor and build it. I'm sure you are all familiar with the "Kraken" which is my vehicle. Going to be going to the next level now. I will be doing Carrillo rods and Pistons with upgraded wrist pins and heat treated Pistons. My question is I was thinking of keeping the stock compression. If someone had any information about that it'd be greatly appreciated. Also the benefit of close decking? I'm shooting for 9's is it truly that necessary? Any bit of info would be appreciated, thanks

    After a bunch of teasers, spyphotos, etc., it's finally here! The highest performance Mercedes-AMG in the lineup is the 2018 AMG GT R. The car receives significant revisions including new active aerodynamics, engine changes, software changes, new brakes, new wheels, new tires, and just about everything that could be changed was changed. Mercedes-AMG unveiled the car today at the Goodwood Festival of Speed as they promised they would. You can watch the whole impressive unveiling event where they bring the car in with a helicopter from the Mercedes-Benz Youtube channel which is posted below. Overall, the car looks absolutely fantastic but this vehicle is about performance and not looks. The engine receives higher compression pistons and new turbochargers. Whomever it was that said they would just change the tuning software was wrong. Very, very, very wrong. The compression is bumped from the M177 10.5:1 but Mercedes-AMG has not yet posted the full specifications so we do not know the new ratio. Regardless, 577 horsepower is now the power output and it is sent to through an even quicker shifting dual clutch transmission. There are weight saving measures such as a lighter flywheel, a new exhaust that weighs 13 pounds less, and carbon fiber pieces abound. No word yet on the curb weight. This is the new king of the Mercedes-AMG lineup and it will go toe to toe with the Porsche GT3 RS or Turbo S and possibly encroach on 488 GTB territory. We can't wait to see it in action.

    AWSAWS started a thread Octane, ethanol in N54
    Hi Guys, so please explain to me something. On some forums I've seen it said, that you should run as little octane as you can get away with, without timing drops/ knock etc. Now I fully understand that adding in more octane without the increased boost and/or timing advance to take advantage of it appears to be a waste. What I'm wondering though is if I'm running E30 fuel (and meth injection), and getting no knock, then is there any point in raising the Ethanol content to E50 or E60? Every molecule of ethanol replacing gasoline is pulling out chemical energy from combustion. However, every molecule of ethanol spraying into the cylinder is having a greater effect in reducing internal temperatures, thanks to it's greater latent heat of evaporation. The aim as I understand it is to spray more fuel. Am I correct in thinking that the targeted AFRs for E60 will have to be closer to 8.5:1 than the targeted AFRs for E30? So will the ideal amount of ethanol to run, be dependent on the targeted AFRs and fueling if boost targets and ignition advance values do not change? Forgetting about the pumps being up to the job, is it possible to add too much ethanol, where the combustion in the cylinder happens too slowly and causes misfires? Thanks guys. I'm always wondering how much ethanol is enough when I visit the drag strip.

    Well, it seems the Nizpro upgrade is real although this is still early. There is a competitive offering based in the US and Nizpro of course is in Australia. They took their E92 335i with factory N54 turbos to the strip and ran an impressive 11.2 @ 120 in the 1/4 mile. That elapsed time for the trap speed speed is very good. This is indicated by the 1.57 60 foot: Make no mistake about it there is room to improve but their transmission is holding together thus far. It would instill confidence to see higher torque launches. At this point, who cares about stock turbo N54 performance? The best test for the trans would be a high load launch with upgraded twins at the very least. More runs and details will come with time as Nizpro ran this car without any corresponding transmission software upgrades. They are clearly doing shakedown runs before going further. So far, so good.

    Whoa! These pictures will definitely get you rethinking the W205 generation Mercedes design. Although the cars are blending together that is not to say the modern Mercedes styling language is bad. Just look at this black Mercedes-AMG C63 Coupe for proof of that. The car is lowered with dark window tint and tinted lights. Vossen wheels in a matte bronze finish round it out but a gloss black finish would look even meaner. Either way, this is a badass C63 Coupe.

    This is incredible considering that AMR Performance already showed a gain of 63 horsepower and 100 lb-ft of torque at the wheels on the 2016 W205 C450 model. That was with their 1.01c tune revision and now with their 1.02b tune revision they take things considerably further. How about 371 at the wheels or in other words another 53 whp from where they already were? That is more than 100 horsepower at the wheels over stock: Utilizing this tune and no other modifications a C450 went 12.3 @ 112 in the 1/4 mile in 98 degree weather. We expect easy 11's in winter conditions or just cooler weather: We are waiting on the slip but AMR is pushing the C450/C43 models harder than anyone else along with the M276 DEL30 engine. #AMR #amrperformance

    The Viper is the best driver's car on the market. It is not even a debate. It is exactly what many so called 'enthusiasts' ask for. A lightweight and perfectly balanced sports car with great response from a naturally aspirated track bred motor paired to a manual transmission. The only problem is those so called enthusiasts do not buy it. Dodge adjusted the pricing dropping it $15k which helped but these days enthusiasts are too soft. The Viper is too loud. It's too hot. The pedals are too close together. There is no automatic option. It's too interactive and too demanding. You f'ing pussies. The Viper is the best thing in the automotive marketplace. It's a giant middle finger to the automotive world. No direct injection. No dual clutch nonsense. No hybrid garbage. Just a giant engine with forged internals designed to take whatever you throw at it paired to a lightweight chassis with a manual transmission. It's all about interaction, speed, and fun factor. Despite not having all kinds of technological band-aids it still is capable of destroying anything at any price point around the track. It even scares the pants off Ferrari. It's a damn bargain to boot. The Viper will be killed off before it should be in 2017 and we likely will never see anything like it ever again. It signals a major shift in the automotive marketplace. When you're driving your hybrid BMW or Lexus with 15 gears and 1500 software modes including one that adjusts the air vents to dry your tears remember you let this happen.

    Charmuth started a thread HELP! in N54
    So I'm disabled and usually I have the person working at the gas station fill up gas for me and always fill up 93 octane but this time he heard wrong and filled up 87 octane (full tank btw), my car is a N54 and has a upgraded turbos, FBO, and a custom tune for 93 octane and the codes I got from driving it back home (drove very slowly) are: 2A87 Outlet - Vanos variable cam control test, mechanics 3100 Boost - Pressure control, deactivation My question is, would some octane booster help my situation if I add some to the tank now?? Thanks ahead!

    Hoping to get some discussion going on the finer points/peculiarities of tuning scaled (3-column) MAP bins. I'm messing with my first one and while it's proving easier than pushing INA0S over ceiling to get 20psi, it brings to light some things your don't see in an unscaled map. For example... I've been trying to smooth out an MAF "dip", for lack of a better word. That's exactly what it looked like to me at first, but all evidence to the contrary. It mostly bothered me since boost control uses it, the dip was smack in the middle of coming up to target and seemed pretty severe. It even fell as boost/RPM increased, but most often, it would stay static for a few hundred RPM and then began to rise again. You'd expect the slope to change as the scaling started reporting lower data, but it seemed excessive. Boost, boost target, WGDC MAF (g/s) (red): After messing with some things, I decided to change my spool mode RPM. It was set for 3000RPM, which also happens to be break points for all kinds of other stuff, so I wanted to push it out of the way to eliminate it as a factor as I moved forward. I upped it to 3300 RPM and, lo and behold, the spot where MAF dipped moved up with it and the start of the "dip" became even more pronounced. The light bulb finally came on. The usual values passed around for 3-column scaling start it ~10psi, so the scaling starts during my spool (somewhere around 2700-2800 RPM depending when I floor it), BUT logs say that scaled boost doesn't take effect until spool mode ends, no matter where that is. jyamona@motiv martial@mhd, there is either an undiscovered MAP (spool) table somewhere or the scaled logic just isn't active during fuel mode 20. Not exactly a crisis, but noteworthy. So, for the time being, I moved the spool mode below the 10psi area (2600 RPM) and the sizeable deviation at changeover to scaled is gone and/or at least in a less crucial area. The "sag" remains due to the scaling and will change with boost/tuning from here on out, but for now, once its hits ~19psi, MAF (purple) comes up and stays pretty linear after that. Maybe everyone knows this already and I'm way late to the party, but I sure didn't find much of anything on scaled maps, so I wanted to get a bit more in-depth discussion going...or at least have a place to post when I get hung up or come across something interesting with it :D

    Kish2604 started a thread Meth system capabilities in N54
    Hi everyone... I need some specific meth system advice on a DIY project, I am planning to run a direct port methanol system utilizing the ffg components from my existing set up, my concern is, will the coolingmist pump be able to supply sufficient volume and pressure to a rail of 6 x cm3 nozzles in a port spacer and a single cm5 retained in the charge pipe for iat suppression? I am planning to T the line of with 1 going to the Cp nozzle and the other to the rail after the solenoid. The rail will have a check valve to prevent siphoning from the injectors. If the single pump isn't sufficient should I run each system independently or can I connect a pump inline with the normal one to act as a booster? All suggestions welcome...

A: Yes, as long as the thread is NOT closed, it's still for sale. Q: How much power does it make? A: Depends on how much boost. See attached dyno sheet below (not my actual dyno).

A: You can use 100% E85 or any pump gas (i.e., 91, 93 octane) but will require a 2 minute flash via MHD app. I will include the Android tablet with MHD app. Q: How can you log? A: With JB4 Connect Kit v3, you simply download the JB4 app on the Android Play Store or IOS App Store then connect via Bluetooth. Q: Can I stream music via Bluetooth? A: Yes via the Tune2Air WMA3000B Bluetooth adapter which the radio sees as "iPod". You can then use SoundCloud for all your music and even use the steering wheel to skip tracks. You can also plugin a USB drive and play music through there as well. Q: Have you done any oil analysis? A: Yes, for the last two oil changes, I've sent an oil analysis to BlackStone Labs. I can provide the reports if requested.

    You have to take the horsepower figures here with a grain of salt. GAD motors obviously builds powerful M157's so no doubt they can deliver 900 horsepower in this ML but without dynos there is no proof either of these SUV's are making their claimed horsepower. The X6M traps 126.8 in the 1/4 mile and the ML63 124.3. That just does not feel like 850-900 horsepower performance even in 5300 horsepower SUV's. The X6M can do about 115 stock so almost another 300 horsepower is an increase of 11 miles per hour of trap speed? Whatever the actual horsepower figures may be these are two powerful German SUV's going at it. The X6M is the faster of the two and beats the ML63 to the 1/4 mile and 1/2 mile marks decisively although the AMG puts up a fight. Hopefully we can get the details on what is done to each but turbo upgrades are a given.

    For my power goals I think 600-650 whp would be enough for me.Looking at Doc and VM turbo kits,looks like the VM 6062 might be the kit for me.Also VM sale and what's included with their kits includes more.Doc starts at 6262 which(I'm no expert here) for my power goals will be little laggy. My car is fbo jb5 G5 ISO,stg2 lpfp fuel it,Burger meth kit,e50-e60 ethanol mix. with what I got is this achievable with the 6062 turbo kit?Eventually I'll do PI. Would there be anything else needed when installing a single?i also have a BMS OCC & a Rob Beck check valve for vacuum.From all you experienced single turbo guys that have installed the VM kits just looking to prepare what I need to have it installed or get parts of,ill probably have a pro shop do it.i don't plan on doing this on my back.think it's best to pay some one that does this all the time.

    Ouch. Volkswagen's image (and stock price) took a huge hit in the dieselgate saga but let's hope this mess will finally be put behind all of us as frankly we're sick of it. The US government and Volkswagen finally came to terms and here are the details. - 482,000 cars involved - VW will pay $1000-$7000 per car depending on age and other factors - VW will fund environmental studies and programs - Settlement includes offer to buy back affected cars This will all cost over $10 billion dollars and this is why Volkswagen may begin to offload assets. Those who have leased vehicles will have the option to terminate their lease. The government is likely to assess further penalties which will require VW to pay into a created EPA fund depending on the calculations of just how much they polluted in excess. The government gets theirs, the lawyers get theirs, VW has a black eye, and business continues as usual. Source
