    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

    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

    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. MOTIV 900 Turbo Kit MOTIV Port Injection MOTIV Twin Disk Clutch Fuel It Stage 3 pump basket BCP Colossal Intercooler VRSF Charge pipe w/ TiAL Q blow off valve MHD Back End Flash by BCP AEM EMS4 for boost control and port injection control M3 cowl Modified stock catback exhaust Tuned in house by at BCP 802whp @ 33psi on E70 fuel Special thanks to Jake @ MOTIV Over 800 whp from a motor with over 100,000 miles on the clock that has not been opened. 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.

    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

    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.

    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

    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...

    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.

    Interesting run here as two tuners put forth S63TU's they tuned against each other with the winner taking $10k. Evotech apparently has a reputation in Europe as not wanting to race unless it is for money otherwise it is a waste of their time. The funny thing is they were not willing to race for $10k but instead agreed to a $1500 run. What happened to the confidence Evotech? Frankly, BimmerBoost does not have too much faith in Evotech's claims as they seem to be exaggerated anyway. The F10 M5 camera car is tuned by BimmerBoost member @lfelunden who has not yet decided on a name for his new tuning company. The M6 Gran Coupe is heavier than the standard M6 so weights are pretty even here. It is surprising how easily the M5 pulls considering both cars are bolt on tuned and if racing for money one would assume at their best. No comment from Oliver Neumann the owner at Evotech at this time although we are told the race loser paid up. BMW M5 F10 HCP mods: Stage 3 software by HCP, catless downpipes and K&N drop-in filters M6 F06 Evotech: Stage 2+ software (Evotechs most powerful), akrapovic exhaust, catless downpipes and intake

    Hi guys, I just finished getting a pro Tune using the cobb platform on my n55 xdrive with newly installed pure turbos stage 2. Other mods include cobb fmic, cobb catted downpipe, charge pipe and afe dry air filter. New spark plugs in. Running 94 gas - petro Canada. Reviewing the attached dyno the results look a little strange to me. At higher rpm it starts to go all over the place. Is this normal? I did feel some stuttering at higher rpm when I was testing out the pro Tune. The pro tuner also advised of this. I may need to go back to him to review it over. Last point I have a catted downpipe and I did read on here that this can be an issue on the turbos. Any tips or advise to avoid any issues please share. Thanks guys
