    This is a dyno of new RBs. The regular old version that have been balanced to 0.2 grams throughout the RPM range. OEM tolerance is 1.5 grams, High performance tolerance is 0.5 grams. These should be able to take a big beating These turbos also have the Thrust Upgrade. This Mustang dyno supposedly reads very low and most are not happy. After the first pull the guy asked me is this right? I said what? He said the dyno it seems very high 475 535. (all pulls in 4th gear. 1st pull 475 535 2nd 472 531 3rd 474 532 the Cobb stg2 aggressive 351 395.) I said I was hoping for 500 he then said this thing is a beast 470s on this thing is an animal. Temperature out was 78 and muggy so was hoping for better conditions. 475 535 was the highest run even though it is not on the sheet, he put my first ever Cobb stg 2 aggressive on there for comparison to now. Its impressive to say the least. I will be at the track Thursday night to see what she can do the 1/4 in. Ok to Terry first thank you for all your help this is a BMS flash that has some tweaks from Ken AKA Wedge, we had to get torque down to allow shifts from 4th to 5th and get fueling scale up for the map. Wedge thank you very much. 4th gear pulls RACE_AT: For use with E85, Methanol Injection, and/or Race gas mixtures Ken Wedge made some adjustments to the above map for fueling and torque issues where it would not shift from 4th-5th at times due to to much torque. 2007 E90 AT JB4 G5 Back end flash Ken Wedge Tweaked FBO HFS Meth kit RB turbos E85/93 E40 blend

    Motiv Motorsport posted a dyno overlay that provides perspective on the difference between two of their N54 single turbo kits and also the impact of their port injection fueling system. The 750 kit in the graph below is using E50 ethanol without the port injection fuel system. The Motiv 900 N54 single turbo kit is using the port injection supplemental fuel system combined with E48 ethanol. The difference between the two is substantial and the supplemental fuel is obviously necessary to hit the figures. Motiv 750: 705 wheel horsepower 680 lb-ft of wheel torque Motiv 900 with supplemental port fuel injection: 829 wheel horsepower 781 lb-ft of wheel torque This overlay is certainly interesting to see as we already saw the record setting Motiv 900 dynograph which touched off a spirited discussion in the BimmerBoost forums. A video has since been added which is below. The automatic transmission is obviously not capable (yet) of reliably handling any of these figures but solutions are being worked on.

    Nice race from our Russian friends here pitting the new breed of German twin turbo V8's up against each other. On the BMW side we have an F13 M6 with a Stage 2 tune from PP-Performance. The CLS63 AMG M157 is tuned by someone who rebrands other tuners tunes. Yes, for some unknown reason MHP still exists. The last time we heard the name they were selling Weistec tunes as their own. From what we have heard first hand, Weistec has distanced themselves from MHP. This 'tune' could be anything considering how MHP and Andrew Cluck have been passed around from tuner to tuner as if he was a drunk sorority girl at a frat party. Well, let's focus on how the cars do instead of how diseases get spread. There are three runs and in the first the CLS63 gets a nice jump. The M6 is able to reel it in and looks like it is starting to pull only for the CLS63 to let off due to traffic. The second run offers a more even start and the M6 again starts to pull. By 167 miles per hour it looks like the M6 has a good 5+ car lengths and is continuing to pull, impressive. The third run is the best of the bunch as the cars have the most even start. The M6 again pulls up top and continues to pull by 167+ miles per hour. In a roll on race like this the M6 has a couple advantages on the CLS63. To begin with, it is lighter by roughly 250 pounds. Additionally, the DCT transmission in the M6 shifts faster. Without seeing a dyno from each car it is difficult to exactly state how these factors affect the race but the result is the M6 pulling decisively on the runs.

    The Good: Long story short RBs are pretty beastly I am trapping 6-8 mph faster than I use to at the track. Comparing Apples to Apples my buddy in his JB4 FBO back end flash car was trapping 116-117 best a 118 at 11.8. A FBO 135 Jake Cobb Pro Tuned car was only doing 112-114 with his best being a 12.1 at 115. So some perspective on the night and an Apples to Apples comparison before I get the ones chiming in I trap 123 on stockers. I doubt that will be done where I run at and this is how the BMW's run here including myself and others. My time slips from last night vs my Last run with my stockers The Bad: I could not launch hard in 2nd due to torque shutting down power then allowing it to shift into 3rd then I would be out like a rocket ship. And yes I have an Alpina Flash Wedge suggested the 2011 Alpina Flash so who knows. Its still a work in progress to figure out how to get all this power to work together while doing a 1/4 mile run. The car is super fast in rolls and great after 2nd has shifted during launches. I will need to play with limiting boost in 2nd for optimal launches without hitting a torque shut down. If I can do that this car is easily 11.1-11.3 car its just a beast but she has to be harnessed. I have GO Pro vids but I need to edit them down so they do not take hours to load on youtube. In the race against my buddies 335 you cans see how 2nd gear falls flat then it shifts catches boost in 3rd and I am out. The UGLY: Another buddy in his E92 stick on his very first pass he tried to launch and broke an axle, UGLY. Anyone have pointers for loading GoPro vids to Youtube?

    One of our Billet Stage 2 customers took his 135 to track and laid down a solid pass that will only get better with practice. 11.6 at 120MPH. Looking forward to you getting your 60 ft time down and dropping that ET! This car was tuned by PTF/Motiv using the Cobb AP. You can head over to the motiv site for more info.

    I wanted to put these turbos to a boost test, here is a 29-30 psi across the board pull, I popped a small boost reference hose to the gauge first pull, which tees to AEM map sensor so it shows lower boost after the shift, but its only because the map wasn't seeing full boost as the hose to the gauge popped off. If anyone had any questions on can stage 2+ hold a LOT of boost to redline, they can, and they can do it pretty easily. You take a BP hit as you see its at around 66psi, just slightly over 2:1. Timing for this boost level is pretty damn solid too, holds 10 degrees to redline, after the shift holds 8-9 all the way up. I will take this all day as well. I fixed the hose and you can see on the next run its showing 30 psi in 4th as well as it was getting the full boost signal. Notice how manageable EGT's are even at these boost, and timing levels, the car is pretty happy here. These can actually hold more boost if I want, but 28 tapering to 25 psi seems to be a good curve for BP, turbo longevity, etc, and where I will prob run them daily. Please keep in mind, the less boost you can run to get to your power goals, the longer your turbos will last. http://www.datazap.me/u/vargasturbot...3-256&mark=202

    First I would like to say, thanks Wedge for hooking me up ;) it was truly appreciated @Josh@Cobb thank you sir for your support @dzenno@PTF your blogs, posts, and suggestions from the olds days, before your became PTF and current were a values and you had, and still have a follower that learn much from ya @enrita thanks for starting this thread, and thanks to everyone who contributed. http://www.bimmerboost.com/showthread.php?25074-HOWTO-COBB-ATR-discussions-maps This was just a scrimage to go out and see what the car was capable of doing in a 1/4 mile run. I was not aiming for ET here, but aiming for speed traps instead. There was just too much torque for street tires on this tune, and I found myself feathering the car half way through 3rd gear. The backend would not stop moving around so I could not give it 100% throttle more till it settled in 4th. Indeed I will make adjustments for this next time. Ill have to designate this map for road kills instead I screwed up big time when I added too much race gas to compensate for the trouble my LPFP was having with anything above E30 at this power level (FUEL-IT STEVE HELP ! :angry-banghead: ) . In the end I had like E20 after adding the race gas :( . However I noticed using race gas my IAT got high quick as apposed to using E50-E60 my IAT never saw anything above 150 when pegging the needle. My IAT was climbing to 160f at the end of the track :facepalm wtf. So that was just a waste, I should of just maxed out my trims for the hell of it so my timing wouldnt have been pulled(no my AFRs stay put even if trims max out). I was targeting 13 timing in the top and lost a good amount of power when timing corrections started Yet again the South Florida weather and humidity is absolutely no joke, its like always being in a sauna. Keep in mind my car is "not cattles" I have the cP-e downpipes with HighFlow 200 cell catts, and OEM mid catts, I weigh 250 lbs and I had just over a half a tank of gas, no meth, full street trim, and no weight reduction. There will be another 335is that will be running the same tune with cattless downpipes, upgraded LPFP, and the driver weighing significanly less than myself, better DA and weather.

    I'm designing twin pump setup for my N54. This will be running with PWM booster, controlled by original fuel pump module. That should prevent the pressure oscillation compared to 2nd pump with relay control. Well, right now electronics are not the first priority. Basic PWM booster is really easy to build, but maybe there could be fail safe function if one of the pumps stop working, maybe external connector for the full power signal and 12v to 15V booster too. 2 x 450 Walbro's seems to produce way too much fuel for my needs (theoretically 60 litre tank depleted in 6 min @ PWM 100%)... and the size of the pumps does make the design a bit too packed. So, does anyone have any experience about Treadstone Performance TRE 340 pumps? The flow charts looks ok, claims to be E85 compatible and they're giving 3 years warranty for those? Google did find very little about the pumps. They look pretty much like Deatschwerks DW300... and what I've read, those DW's are not so reliable? Any info is appreciated. Some sketching single 450 vs double tre300...

    I'm running a variant of the bms E85 flash modified for E60 with a 3D scalar with some help from Justin (v8bait) and wanted to know how much the 3D scalar helps for fueling efficiency I'm running the inline lpfp upgrade w/ stock cats (just had two new turbos installed under warranty) my trims seem fine and since I'm catted I was wondering if the 3D scalar is really helping me at all. Anyone dyno the same flash with and without a 3D scalar? I've been optimizing my flashes for 1/8 mile runs (only safe distance I have to test) as well as logging with the jb4. Haven't seen much difference between the 3D vs non-3D scalars settings. Also, who else is running aggressive backend E85 flashes with the stock cats? How much timing and what kind of afr targets?

    As most know, Fuel-It! has been working with Vargas Turbo Technologies and MOTIV Motorsports to develop a new product to meet your needs. Now that their products are about to start shipping we would like to officially announce the release of "THE HULK". (shown with optional return) This is no ordinary fueling solution for any ordinary car! Just like the monster lurking under your hood, this beast is just waiting for a chance to shed it's civil demeanor and show you what its capable of. With "THE HULK" installed and restrained, you can resume your normal daily activities. While commuting this dual stage pump's primary is controlled by the DME and the secondary lies dormant. However, the moment you mash the throttle, it's true colors show themselves and the secondary comes to life releasing "THE HULK" within and leaving everyone green with envy. With up to four times the flows of the stock low pressure fuel pump, this assembly can handle whatever you can throw at it.....and then some! A few specs and particulars... Primary... Pump: Walbro 450 Control: PWM via the DME E85 certified: Yes Flow: 1.0GPM @ 13.5V Secondary... Pump: Walbro 450 Control: User defined E85 certified: Yes Flow: ​2.1GPM @ 13.5V Installation... Stage 3 is installed just like the stock LPFP and the electrical and plumbing connection points are all stock. The primary runs off the stock electrical system and there are no modifications made. The secondary requires the installation of an additional wiring harness. We will be providing the wiring, relay, and fuse assemblies for this installation. It will be up to the user as to how they trigger the secondary. Those running JB4 will be able to utilize the "nitrous trigger". Those running port injection may choose to use their secondary PI controller to trigger the secondary. For those running dual HPFPs or some other configuration, you may choose the optional Hobb's switch to control the secondary via boost. Options... FPR: To assist those customers that will be running an external Fuel Pressure Regulator (FPR), we will offer an optional return line connection point and a stock FPR block off kit. The location of the return has been optimized to flow back in to the bucket to be recycled under high demand and is a simple quick release fitting. Hobb's switch: As mentioned we will also have the option to purchase a normally open Hobb's boost controlled switch to control the secondary. You can view these options on our website and we are taking pre-orders that will begin shipping Nov. 3rd. Supply at this time for both domestic and international customers is limited due to the availability of core assemblies. Consequently those orders will ship in the order in which they were received. We appreciate your patience while we build up those inventories and work to meet demand. http://www.fuel-it.biz/e-series-stage-3-lpfp-upgrade-options/

    Hey guys, I was able to attend a small half mile event at Minter Airfield today and put the new M3 through it's paces. I was expecting there to be around 30 various cars there but for whatever reason only 8-10 showed up. Sadly all faster than the M3. So I wasn't able to get many real races in. In fact many of my runs were solo. But I was able to get all the half mile racing data I needed. And had some fun in the process. For the most part I ran the car on map 7 with a 50% race gas 50% 91 mix and it performed flawlessly. I did a few runs from a 40mph roll and a few from a dig. The new boost limiting in 1st really helped the dig launches on the dusty runway. And the new logging functions on fuel trims, dual bank AFR, etc, came in handy as well. As far as results go MPH at the half mile ranged from a worst of 150.4 mph on a botched dig start to a best of 154.5 mph from a roll. Which would put it ahead of most RB FBO N54 335s, and only 1-2mph slower than our (late) tuned/race gas/exhaust M5. Not bad for a tune only car. The closest races I had were against a sharp looking new McLaren. I think it's a 12C model but I don't know the cars well so someone correct me if I'm wrong. Anyway the M3 held up well from a dig and a roll but the McLaren had a couple mph on it both runs. It was fun watching it's spoiler pop up as it was braking from 155mph. He mentioned he was looking in to some piggyback tune for it that I think is 6k. lol. Some vids of those runs:

I was planning to keep the car, but the M4 keeps running in my head and it's on its way here in few more days; thus, I'm selling the 335i. -New turbo replaced 1k miles ago -Full bolt-on (upgraded FMIC, downpipe, DCI) -BMS Oil Catch Can -M3 control arms/strut bars -Sport package -Convenient package -Folded back seats -Alpina TCU flash -Auto trans -Cobb v2 -Walnut blasting was done last year -New 3, 4, 5th injectors (1, 2 and 3th were replaced by dealer under warranty before) -Oil pan & gasket was replaced last year as preventive maintenance -Brake and differential fluids were flushed/replaced last year -New Pilot Super Sport replaced few months ago As you could see I was really trying to keep the car, thus all the money spent. My loss is your gain! Never been to a track nor drag strip/street race. Only inspirational runs now and then. Mint condition. The pics will speak for itself.

    Hello, This is one of my first threads over here at BimmerBoost. I had been visiting e90post but I have been frequenting this forum more and more. I hope you all find this of value. I would like to post my review of the Markert Motor Works solution for a proper clutch type limited slip differential for the E9X cars and E8X 135 cars. I have previously driven many applications outfitted with the other gear type differentials and I was never close to satisfied. It just didnt feel like the earlier BMWs I know and love. Afterall, it was the E30s and E36s that got me into this rodeo. I was thinking, why cant my e90 have a similar feel? I thought it was because it was a turbo car, and that I needed a V10 to solve my woes. The lock up was never smooth coming out of corners or a nice slip angle, and they were always seemingly very noisy compared to a proper clutch type diff. Boy was I wrong about turbo vs NA! Friday came around and I knew I would be having my new differential assembly installed that evening. I was very excited. Low and behold, I had a friend drop by with an identical car to mine (2010 LCI sedan, alpine on black 6 speed). He has a wavetrac in his car so I drove it so that I would have a comparison. After the test drive, and I mean test drive ;) I brought the car back and I still was not that thrilled. It was making me nervous about my car and how it would feel after the diff swap. Come 6 o'clock, I get my car back with the new differential installed. I pulled out of the parking lot, and I immediately screamed "I love my car again!!!" (while completely sideways coming out of it smoothly and precisely as a professional driver). I immediately thought, "now no longer need the S85" (although the want is still there). I could not believe the transformation. It was incredible! :happyanim: I then began to call everyone I know with a later model BMW to tell them the news. This thing is BRILLIANT! You MUST get one! So far I have two other buddies get them (both members so I am sure they will chime in). One in a 335i and one in a 135i. Both FBO. Pics!: Install: Obligatory burnout: Lastly: Funny Meme a friend made due to my extreme happiness: But all shenanigans aside (even when not driving like a hoon) you can notice the traction control not having to work as hard. Launches from a stop are now much smoother and thus quicker out of the hole. Exiting corners is the biggest plus, since the lock up is progressive versus On/Off, it is extremely smooth. No more of that craziness coming out of turns (which in my opinion was extremely dangerous). Link to their site: http://www.markertmotorworks.com/#!e9x-e8x-clutch-type-lsd/cjl5 Make sure you all check these things out! Talk to yall soon :thumsup:
