    Custom set of Hybrids that started as RBs but are far from RBs at this time, Tuned by a local tuner from another platform and upgraded rebuilt hybrids by another turbo guy from that platform, done on a dynojet ... Pretty Bad Ass to say the least... Using jb with backend flash obv custom tuning by someone here on Long Island... Funny thing is this shop has no interest in this platform other than this being a employees car and them messing around here and there.... The 587 graph has gotta be the record right? Stock fuel system with a inline pump and I dont think much more than e50 :) Just shows what tuning can be done on the dyno by people who understand tuning in general, which 99% of the n54s dont get done (tuning on a dyno by someone sitting in that car on that dyno) The video i have was sent to me from an iphone to my android to the quality is murdered, but its here, this is a 6m 135i ..... PM or write your email if you want the video but he broke the 565 before i got done writing this so 58x+ is coming soon in higher quality...

    Got the all the final samples back today except the pulley, they broke a tool an its supposed to be done Friday. The housing, and mounting plate have to made in 2 pieces to keep machining costs down, this means we have grooves machined in that accept the plate, and then we have each housing Tig Welded. We will have this one welded tomorrow, and get it test fit soon, as long as everything fits as it should, we just have to final assembly fit on a the test vehicle, and start a machining run. A run of parts can take anywhere from 30-45 days depending on how backed up the queue is, sometimes longer, we are hoping they can get them done quickly for us. Excited to get these things out there, and running on some fast cars. Thanks for your patience!

    Dinan is a reputable and high quality aftermarket option in the BMW tuning world. However, the BMW tuning world has changed and Dinan has had to change with it. Dinan announced their piggyback tuning era (after stating piggyback tuning was inferior) earlier this year. Now Dinan releases their S1 package for the F10 M5 claiming 675 horsepower thanks to the Dinan Dinantronics performance tuner along with other supplemental modifications such as to the suspension. There are a few problems here. First of all, Dinan's piggyback box is $3,749. Why? What does it do over a JB4? What does it do over other piggyback tuning options? If Dinan wants to command the highest price point in the marketplace for a piggyback tuning box that is fine. It's fine if it's worth the money. From what BimmerBoost has seen, it isn't. Dinan can't live off his name any longer. In the old days Dinan would 'congratulate' the BMW engineers by saying they could not improve on the BMW tune (although other tuners could). Today, consumers have more options and the options other than Dinan offer more data on the performance gains and also offer their product at a comparable value. If Dinan wants to charge more that is up to Dinan but you would expect more data for the premium with Dinan's resources. Not a single timeslip? Not a single dynograph? This all goes back to Dinan's arrogance about dynographs and the white paper Steve Dinan released criticizing using dyno's for proof of gains. The reason Steve Dinan does not post dynographs is simple. It does not favor his product especially for the horsepower per dollar when it is relatively easy to compare graphs for competing products. Call this the N54 or BMS effect if you want but the BMW turbo era already proved more money does not equal more horsepower, safety, or performance. Dinan is releasing horsepower charts so clearly he sees he needs to change his approach. The Dinan name carries a lot of weight. However, it's with the uninformed. BimmerBoost users won't be ponying up for this without results to back it up. You want $13,487 for what a JB4 for a few hundred bucks with some methanol will smoke? Sorry Steve, the game has changed. You better change with it or it's game over. Dinan releases 675 horsepower tuned M-sedan that delivers supercar performance with the refinement and ride of an opulent daily driver. (Morgan Hill, Calif.) – August 2014 – BMW performance specialist, Dinan Engineering, has announced the latest addition to its signature vehicle line, the S1 M5. This twin turbocharged V8 powered sedan offers supercar performance with 675 horsepower and 644 lb-ft of torque on tap, but is refined enough to be the perfect daily driver. The 200 mph capable M-car features a comprehensive blend of components designed and tuned by Dinan, recognized for 35 years as the BMW tuning expert, to enhance every aspect of the vehicle’s performance. The S1 M5 offers the only warranty on the market that matches manufacturer coverage for 4 years/50,000 miles and on both the standard M5 and Competition Package equipped vehicles. The S1 M5 offers remarkable performance and the same warranty coverage, resale value and reliability BMW owners expect, all backed by Dinan’s nationwide network of authorized dealers and service centers. “Our goal at Dinan is to build a balanced performance package that maintains the soul of the OEM platform,” said Dinan Engineering President Steve Dinan. “This car is designed to be faster and handle sharper, but still offer the level of refinement that BMW owners expect. M-Car owners already bought the fastest BMW and now it’s up to Dinan to make it even faster” The S1 M5 makes a jump from 560 horsepower in stock trim, to an impressive 675 horsepower and 644 lb-ft of torque thanks to Dinan’s Carbon Fiber Cold Air Intake, Free Flow Exhaust system and the all new DINANTRONICS Performance Tuner that opens up the full potential of the S63 V8. The DINANTRONICS Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It was also designed to be emissions legal in 50 states (E.O. Pending). The ultimate objective was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package. To compliment the added power, the package includes negative camber front control arms, lightweight tubular Anti-Roll bars and Dinan’s High Performance Adjustable Coil-over System that gives the M5 a more aggressive stance and decreased body roll, without sacrificing ride comfort. Dinan’s adjustable coil-overs keep the factory Electronic Damper Control shocks in place and implements threaded collars to allow the user to change the ride height. The end result is a sleek lowered stance that provides improved handling to go along with the more aggressive appearance. Optional features include Dinan lightweight forged wheels (custom finishes available) and cosmetic upgrades from the BMW performance parts line that includes a carbon rear spoiler, a carbon front fascia and Dinan aluminum pedals adding a unique aesthetic touch to any 2011-2015 BMW M5. Dinan has worked closely over the years with BMW’s factory motorsports program bringing home three consecutive championships and two wins at the 24 Hours of Daytona along with countless Grand-Am podiums. With 35 years of experience building artfully engineered performance vehicles that balance tuned handling and dramatically increased acceleration with the turn-key reliability sport sedan owners demand, the Dinan S1 M5 offers supercar performance in a practical package. This package is also available for the M6 and Competition Package Equipped models.

    So Iím sitting here wondering about "you" the userís single turbo experience. I have recently purchased my kit (VFF900) and I'm awaiting install within the next 3 weeks. Over on the other forum e90**** most seem to bash any of the products, from what I call the "Iím too broke to afford, so lets hate" attitude. Obviously human nature gets in the way and makes me question my purchase, but Iím in too deep now to turn around. So lets have a good discussion from well educated people willing to offer good advice. This isnít about what kit is better, but rather the overall experience. Lets discuss some do's and doníts. possible tuning advice (Iím going to be running jb4), and any overall experience to be had. I would love to learn and come out from this discussion 1st off happy I made the purchase, but mainly learn from the people that have been in my shoes, so that this becomes and experience to not be forgotten. Look forward to some great discussions and advice and input from everyone!!!!

    This race is simply a beatdown. To those that know the cars it should not be all that surprising. Both cars feature tunes from PP-Performance. The C63 AMG Black Series M156 engine is already in a high state of tune from the factory. As the 6.2 liter M156 engine is naturally aspirated and tuned aggressively by AMG there is not much room to gain power on the car. Certainly not as much room to gain with a tune as there is with the turbocharged M4. The cars put out very similar wheel horsepower figures in stock form as the C63 AMG Black Series shows ~430 wheel horsepower on a Dynojet. With a tune this can approach the 460 wheel horsepower range depending on how aggressive the timing is and the fuel quality. The stock torque figure is roughly ~405 lb-ft of torque at the wheels whereas the S55 in the M3/M4 shows 429 lb-ft of wheel torque stock. Once tuned, even with a modest tune, the M4 exceeds the C63 Black Series. Horsepower rises to over 479 at the wheels and torque at the wheels goes to 484 lb-ft. Combine the power and torque advantage with a quicker shifting dual clutch transmission and the M4's roughly 400 pound lighter curb weight and you get the result you see here. Not to mention the C63 AMG Black Series aerodynamics also create more drag. The M4 continues to pull impressively to 175 miles per hour and the C63 AMG Black Series is too far back to even be seen. AMG fans will no doubt be quick to point out that if you boost the C63 AMG Black Series things change in the other direction.

    Vertigo started a thread P/P N54 Head in N54
    I just got the call last week that my head was ready to be picked up. Very happy with the work! To save on cost I decided to take on polishing the combustion cambers which is coming along nicely. I'm not going all out and didn't see any need for over sized valves as this is a spare head. .003 was taken off the deck but I am pretty set on using the stock (not thick) head gasket as I don't want the quench area to be too tall and have too much of the steel gasket sealing ring exposed during combustion and retaining heat. Between DI, running E85, and losing a slight amount of CR to the polishing of the CC I think I am making the right choice as this will be a daily driver and don't want to lower my CR too much. Once I decide to add a single, my hope is that the E85 will allow for higher boost without knock.

    Two turbocharged all wheel drive german luxury performance sedans going at it here. The Audi RS7 offers 560 horsepower stock from a 4.0 liter twin turbo V8. The Porsche Panamera Turbo has a larger 4.8 liter V8 that is also twin turbocharged but it is less powerful rated at 520 horsepower. Porsche offers an optional power kit for roughly $20k that boosts the output into the 540 horsepower range thanks to upgraded turbochargers and more aggressive tuning. The Porsche Panamera Turbo uses a PDK dual clutch transmission whereas the RS7 uses a more traditional automatic. The weight between the two is a wash in the 44XX range. We have already seen the RS7 beat the Panamera Turbo decisively in a straight line but does the power kit change the outcome? No, the RS7 is still faster. Even if the more powerful Panamera Turbo S with its 570 horsepower were put in place of this Panamer Turbo the RS7 still looks like it is too strong to overcome. The RS7 despite its smaller motor and lack of a dual clutch transmission simply is the stronger car especially considering just an ECU tune gets it into the 10's in the ~130 trap speed range. The RS7 is a beast.

    So when you upgrade to M3 front control arms on a 335i (both lower and upper arms) you essentially gain neg camber by pushing out the lower edge of the front wheels if I understand correctly. This essentially widens your front track and was wondering what kind of overall effect this has on stability/handling in general? Doesn't the M3 come with a wider rear track than 335i cars to match the wider front (with stock M3 arms)? If so, what negative effects if any would you get (compared to M3) since now on the 335i (after installing M3 front control arms), the front track is wider than the rear and sort of unbalanced as far as track width goes front to rear?

    A sport utility vehicle against a BMW M car? The thought used to be absurd. The thought of Porsche producing an SUV used to be absurd too. Times have changed and now we have two Porsche SUV's with the Macan Turbo being the newest entry into the Porsche performance SUV lineup. Quite the entry it is with its 400 horsepower 3.6 liter V6 engine, all wheel drive, and 7-speed dual clutch PDK transmission. On paper the two vehicles are close in power but the edge goes for the F80 M3 and the edge in power is considerable. First of all, the F80 BMW M3 is very underrated in its output. It is closer to 500 horsepower than 400 horsepower. It also is not sending power to all four wheels but the rear wheels making for lower drivetrain losses although it also makes it harder to launch off the line. Both vehicles have dual clutch transmissions so that is a wash. The Macan is heavier by roughly 700 pounds. The way the race should play out is the Macan getting a slight lead and then the M3 should pull past it after second gear and keep pulling with relative ease. That is exactly what happens. The M3 destroys the Macan Turbo which is no slouch with its 0-60 in 4.5 seconds, 0-100 in 11.1 seconds, and 13.1 second 1/4 mile. The M3 just has too big of a power to weight advantage with 0-100 coming in 8.6 seconds and the 1/4 mile in 12.4 seconds. Past 100 this is no longer a race especially as aerodynamics at higher speeds favor the M3.

    As much as it pains me to say it, I'm moving on from my N54 to the VW MK7 Golf R. As such I haven't any use for my Cobb AP I purchased in June of 2013 for $986 in Plano, TX. Holler if you have any interest as I'm happy with 50% back :) I might also be open to being convinced that I'm a complete moron and I should stick with the N54 platform. It simply seems all of the great mods are for the 1 and 3 series here, and the 5's are getting left behind... The VW Golf R with the Stage 1 Revo will do 0-60 in 3.6 seconds which is pretty darn amazing for a 4 banger.

    When installing my VRSF chargepipe, I noticed that the plastic cap for the positive terminal on the alternator was missing. I guess it got knocked off when my stock chargepipe blew up / shot off, as the bolt that holds the stocker bracket on was gone also LOL. So, I tried looking up the part # on RealOEM and have not been able to find it. I found this diagram, but item 9 in the diagram does not have a number http://www.realoem.com/bmw/showparts.do?model=UC73&mospid=50622&btnr=12_1339&hg=12&fg=29 Can anyone help me out here? I currently have a crappy piece of plastic rigged over it and zip tied so nothing metal touches it accidentally.

    A Volkswagen Golf R going up against a tuned F13 M6? Sounds like a mismatch and normally it would be if this particular Golf R did not the have the HGP 3.6 liter VR6 turbo package. HGP Golfs have shown great results against stout opposition such as a Ferrari 458 Speciale, tuned Nissan GTR, and an Evo X with a turbo upgrade. The first race in the video has the M6 and HGP Golf square off and the Golf beats the M6. It is important to note the Golf R has all wheel drive traction which really helps it as the 1/4 mile elapsed time of 10.672 for the Golf R versus 11.910 for the M6 shows. The Golf also beats the M6 to the kilometer marker getting there in 19.366 seconds whereas the M6 takes 20.770 seconds. The M6 is pulling harder at the kilometer marker by 2.5 miles per hour. The next run has the HGP Golf go up against a stock Lamborghini LP560 Gallardo. Power is on the side of the Golf with its roughly 700 horses. The Gallardo gets a nice jump off the line but the Golf has no trouble running it down and passing it. The HGP Golf R is much quicker than the LP560 out trapping it by almost 20 KPH in the standing kilometer which is certainly impressive. A Golf clowning a Gallardo? Yep. The final run is the HGP Golf versus a Gorilla Racing Stage 3 CLS63 with a claimed output of 840 horsepower. The CLS63 AMG should take the run based on that output figure but struggles with the Golf which beats it badly off the line. The CLS63 AMG can not make up the gap and is beaten soundly although it is pulling just under 6 KPH harder by the kilometer marker. From a roll the CLS63 AMG would win but if it can not run down the Golf in over a half mile, well, that shows just how impressive the HGP Golf is. The HGP Golf R beats all three cars it goes up against and although it does not have the outright fastest trap speed it has plenty of power and is able to put its power to the ground. Sometimes that is more important than peak horsepower figures.

    Last month German publication Sport Auto compared a 1992 E30 M3 DTM car to the F80 M3 on the Hockenheim and the E30 DTM car crushed it. This led to F80 M3 fanboys stating the comparison was not fair because the E30 M3 DTM car is a race car and the F80 M3 is a street car. Apparently a three decade old design with a naturally aspirated four banger beating up on the pride of the modern M division ruffled some feathers. Well, here is a comparison with an E30 M3 that is much closer to the street car. The 1987 FIA Group A car is less powerful than the E30 DTM car and even closer to the E30 M3 street car. Additionally, Mid-Ohio is a larger race track than the tighter Hockenheim that gives an edge to power meaning the straightaways favor much more powerful F80 M3. Before we get into which car excels where on this racetrack we want to highlight the difference in powertrains here. The E30 M3 has a four-cylinder which was developed specifically for FIA and DTM racing. The four-cylinder offered higher revs than BMW's inline-6's at the time and sitting further back in the chassis it offered better balance. The S14 as it is fondly remembered was developed by the same man responsible for BMW's insane 1500+ horsepower turbo four cylinder engine era: "The engine was a highlight. Although there was an internal push to use one of BMW's signature inline-sixes, M technical director Paul Rosche, the mad genius behind BMW's 1400-hp, four-cylinder Formula 1 engines, wanted the balance and high-rpm stability of a twin-cam four. To make the first prototype, he literally sawed two cylinders from the head of an M88—the 24-valve six from the M1 supercar—and paired it with a version of the iron block used in the 2002tii. (Fun facts: The F1 project started with that same block, and Rosche was later responsible for the McLaren F1's V-12.) Test engines vibrated themselves to pieces but produced around 200 hp and more than 7000 rpm." So in the F80 M3 you have modern BMW M power with forced air providing close to 500 horses and in the 1987 E30 M3 Group A car you have an S14 four-cylinder spinning to around ~8000 rpm with roughly 320 horses. The later DTM cars had more displacement and revved to roughly ~10000 rpm with 340+ horsepower. The DTM car obviously offers a bit more power, torque, and tighter gearing. The weight difference between the two cars is about 1400 pounds which is night and day. So how does this play out? The F80 M3 dominates the straights and the E30 M3 dominates the twisties. The end result is practically a wash with the F80 M3 coming ahead by three tenths thanks to its shift speed and straightaway advantage. The comparison plays out exactly as it should. The new car is more powerful and technologically advanced but the track oriented E30 M3 is still more than a match on the roadcourse. Very different M cars but it is certainly interesting to see the past and present compared: Source

I had my friend install the wheels on my car, and he told it did not clear the strut, so he used a spare 15mm spacers. It cleared, but I think it pokes out to much from the fender. So my question is, what is the minimum size spacer i should run on my set up to clear the strut?

    jake1829 started a thread RE: Backfires on the N54 in N54
    Hi Guys, I have owned the car for over a year now, Itís a 2009 E92 from the UK - picked it up with around 24,000 Miles on the clock Within a few short months, the car was FBO and I was doing monthly track days. I spent quite a bit doing preventive maintenance as I knew I was going to be pushing the car with DD and doing track days ē Walnut blasting ē Replaced all coilpacks and spark plugs and now running the NGK plugs ē Oil change every 3000 Miles Now the last 2 months I have had issues with car and bit of coin to get it all sorted. ē Failed front turbo seal Ė decided to replace both turboís as the car had done now 43,000 Miles I had the workshop do an engine compression test as I was curious to see how the engine had been holding up since the tune/tracking etc Results: Compression was approx. 160 psi +/- 5psi (actually very even) on all cylinders on a cold engine. After a month of replacing the turboís, I noticed that my whiteish smoke with a blue tinge was coming from the exhausts on deceleration. Had the car sent back in to find out what was going on, and the shop came back with the following: Check oil smoke coming out of exhaust, on overrun/back on throttle Check oil level - ok, within min/max. Check crankcase pressure - within tolerance at time of check. Remove aftermarket oil catch can and check quantity of oil - very little at time of check, disconnect breather and run engine - no change. Disconnect charge pipe from throttle body, check for oil - ok, run engine with charge pipe disconnected - no change. Disconnect exhaust system at down-pipe connections and check for signs of oil at back of turbo's etc - ok at time of check. Suspect that oil bypassing at valve stem seals - smoking occurs after (normal) vacuum present in manifold, then throttle opened again. Also, no smoking apparent when engine held at constant higher revs (part load). So now it looks like I am going to need to replace the valve stem seals to fix the current issue I was at the local BMW meet the other day and caught up with a new member who was commenting on how he had seen me on the track etc and how my car was spitting flames from the exhaust etc So I was curious on why the valve steam seals had failed, as other people are pushing their cars way above my HP/tq etc I then came across this video: Which raised more questions :S I noticed some comments on how backfires could damage valve steam seals etc Ė not sure how true that tho! These vids are with me running the OFT with a wedge map for e50 Ė I have moved onto the JB4 recently Ė havenít done a video yet to see if the car still spits flames with the IJOES E85 backend + Map7, probably will do this weekend to test You can hear the backfires: Now I know those are def not the burble from the exhaust(23 secs into my vid): So , is backfires normal on FBO 335iís on E85? would appreciated the advice thanks My mod list: | Stacked JB4 + Flash Tune | FFTEC In-line Fuel Pump | AR Downpipes | Active Autowerke Bov | Active Autowerke Exhaust | Active Autowerke Race FMIC | Active Autowerke Strut | BMS Dual Cone Intake | BMS Oil Catch Can | BMS Thermostat | WaveTrac LSD | Evolution Racewerk Sport Oil Cooler | Michelin Pilot Super Sport tyres | Lux Angel eyes | KW V3 Coilovers | Vossen CV3 Wheels | DEFIV lockdown kit | Cyba Air Scoops | Arkym front lip | carbon side splitters | M3 Front & Rear Suspension Conversion | Apex EC-7 Wheels | Toyo R888 tyres | NGK 5992 Spark Plugs |

    No meth heads, meth kits or meth pipes. BMW F10 M5 made 670.8whp (771.42hp) measured on a good dyno with tune only. This M5 was tuned with our new direct ECU flash. We can now program the exhaust blip and the traction system, so it's not too sensitive which relates to more traction. This is also available for all 2014 cars with the new encryption. Speed limiter is removed and the transmission is also programmed. http://www.6speedonline.com/forums/bmw-m/344269-ecu-tuning-group-bmw-f10-m5-made-670-8whp-771-42hp-ecu-tune-only.html Anyone knows of these guys ?
