    Pure Turbo dropped off their M4 for a little JB4 dyno tuning. The car has a JB4, full exhaust, factory intake system, racing fuel, meth kit running dual CM7 nozzles (overkill with the race gas... but better safe than sorry first time out), and of course the hybrid turbos. It is a manual transmission. There were a few little bugs to work through but the end result exceeded my expectations. I'm pretty impressed with these turbos. Spool is delayed maybe 300-500rpm, similar to RB N54s vs. stock N54s. But damn does it hold more power to redline. There is probably another 30-40 whp in them but since it's not our car I didn't want to push it "too" hard.

    Hey guys, Pure Turbo dropped off their M4 for a little JB4 dyno tuning. The car has a JB4, full exhaust, factory intake system, racing fuel, meth kit running dual CM7 nozzles (overkill with the race gas... but better safe than sorry first time out), and of course the hybrid turbos. It's an MT. There were a few little bugs to work through but the end result exceeded my expectations. I'm pretty impressed with these turbos. Spool is delayed maybe 300-500rpm, similar to RB N54s vs. stock N54s. But damn does it hold more power to redline.

    j_hynson started a thread Single Turbo Build in N54
    As some of you know i made a bad choice to go with a single turbo kit from a new company in the beginning of 2014 when i purchased my 335. Well that went terribly wrong and as usual I learn the hard way. After all that was straightened out I decided no more corners would be cut on this build when it comes to anything. I have alot of catching up to do with this build thread. Here is the car before i began building it. I had all the basic bolt ons... Charge pipe, meth, Jb4 (then later switched to cobb when i decided i wanted to go to single turbo), 7" FMIC, Fuel-IT stage 2 bucket, back end flash, etc etc. Currently i have the motor, tranny, and rear diff pulled from car. Head: VAC Motorsports getting stage 3. I originally sent it in just to do end of the year port and polish special but that didn't last long. Here are some pictures i received before they smoothed it out by hand. Will upload more when i receive more pictures Manifold: FFTECH's Top Mount Kit Turbo: PT 6766 (the one on the left is the one im using. One on the right is for a srt8 jeep build) Fueling: -Motiv Motorsports fuel solutions kit. (sorry AEM ems 4 not in picture) -Fuel-IT Stage 3 bucket (LPFP) Rear Differential: (Currently Working on) -Mfactory LSD -Defiv Lockdown Kit Intake manifold design im considering -Had drawn up a rough design of an intake manifold for this build and sent the file off to a buddy that does aerospace engineering over in Europe. He sent me back this and said this would be the most efficient manifold design. I do not know if this is his marked up design or if he sourced it from somewhere else but its pretty close to what i sent him. The only thing im debating is...is it really going to make a big enough difference to justify spending money on materials and adding more downtime on my car to build it. Extra pictures i had in my phone: Ill be leaving to a rig on tuesday but am told i will be back on the 22nd. (anyone who works in the oilfield knows thats probably bs) I will update with more pictures as i go.

    So, I guess I can't, or rather don't want, to keep my lips zipped anymore. Like many of you, I made a little purchase a while back and want to share it with you guys. I'm going to just leave this link to the photo album HERE for right now, and I will update the thread by the end of the weekend to embed the photos and more about the Motiv 900 kit. Enjoy! Edit:

    Got a 2015 Mustang GT and are looking for some torque? Well, consider the a twin screw blower. The stock 2015 Mustang Coyote V8 is no slouch with 360 rear wheel horsepower and 315 lb-ft of torque. The stock torque is also quite nice and fairly flat holding well until redline. Now imagine moving that whole curve up a bit. That is what the Whipple 2.9 liter twin screw supercharger does adding 185 lb-ft of torque at the wheels. It is also interesting to note that the Whipple holds the torque increase until redline making for a horsepower curve that just continues to climb. This is the advantage of a twin screw with its efficiency up top compared to a roots blower. With a built motor this car would be capable of much more but 647 wheel horsepower on 91 octane pump gas and 11 psi through the stock exhaust system and stock motor is incredible.

    A record is a record is a record. Context however is vital in understanding the record. What were the specs? Where was it achieved? What were the conditions? What was the launch? What fuel? What boost? This can go on and on but there are obviously many variables when trying to set a 1/4 mile record. Due to these variables we often see differing elapsed time and trap speed records as the two numbers although related are influenced in different ways. You are about to see how a trap speed figure or fastest measurement differs from the elapsed time and quickest measurement. The previous record stood at 126.51 miles per hour in the 1/4 mile with a JB4 tuned F80 M3. That trap speed was achieved on a 11.807 elapsed time with a 2.143 60 foot or short time. Notice how this compares to the F80/F82 M3 and M4 1/4 mile elapsed time record which stands at 11.18 @ 123.56 miles per hour. That elapsed time achieved with a 1.659 60 foot time. So the quickest S55 powered car in the 1/4 mile runs 11.18 yet its trap speed is lower than the 11.807 @ 126.51 run recorded by an F80 M3 with a 2.143 short time. Now the fastest S55 mile per hour is 127.53 miles per hour but it was recorded on a 12.40 pass with a 2.456 60 foot. Is this a record set by having the most powerful F82 M3 or due to wheel spin? Well, it's wheel spin and cold weather in all honesty although PBIR in Florida is not famous for negative density altitude in the winter. These cars are all running the same JB4 tuning box from BMS. They are all capable of the exact same thing. They are all basically as fast as one another with the differences depending on the supporting modifications, map run, fuel, etc. It is no accident the fastest S55 1/4 mile time comes with the most wheelspin and that the quickest S55 1/4 mile time comes with the best 60 foot time. Is this a record? Yes. Is it due to good drag racing? No. Is it due to a superior setup? No. It is just how things sometimes go on the drag strip and with simple analysis to put it in context it all makes sense. The race for the F80 M3 and F82 M4 trap speed record should not be who gets the most wheelspin. It should come with an impressive elapsed time in conjunction. JB4 F82 M4 on map 7 with E30, no other mods:

    The new Series R1 line debuts with a single style with design cues from the most intricate HRE street wheels, engineered for optimal performance on any track machine, such as the BMW M4. The R1 is available in diameters ranging from 17 to 19 inches, widths range from 7 to 14 inches and weights ranging from 17 to 20 pounds along with configurations for center lock vehicles. All HRE wheels are engineered to minimize unsprung mass and rotational inertia for optimal acceleration, handling and braking performance. Each wheel is built-to-order and there are nearly infinite fitment, color and finish options available for the ultimate custom-tailored wheel buying experience.

    Developments in the BMW F-Series flash tuning scene are proceeding faster than expected. Earlier this month BimmerBoost brought you the story that BMW F-Series Infineon tri-core ECU's had been cracked and the various cracks have spread like wildfire to tuners throughout the globe. Jailbreak Tuning posted flash tune results on 91 octane for the F10 M5 S63TU V8 and the numbers are very encouraging even at this early stage. Peak power went up from the 539 wheel horsepower baseline (with aftermarket downpipes) to 617 wheel horsepower for a gain of 78 horsepower at the wheels. The tune deletes the CEL (check engine light) caused by the downpipes. The torque figure rises from 507 lb-ft at the wheels to 567 lb-ft at the wheels. Torque gains are seen throughout the entire curve once the turbos spool. F10 M5 tuning and S63TU V8 tuning is ready to take the next step forward. 2015 is going to be very interesting for BMW aftermarket performance.

    Very interesting runs here featuring a tuned F82 M4 going up against two stock Corvettes. The first race has the M4 run a stock C7 Corvette Stingray which features the new 8L90 8-speed automatic transmission that GM claims shifts faster than the Porsche PDK dual clutch gearbox. Based on the result there is no reason to doubt the claim as the Corvette is able to pull. It does so up top so this race is not won by shift speed as much as the top end of the LT1 and the sleeker C7 shape. The M4's torque offsets the C7 down low but the S55 just did not the have enough top end in this one. The 8-speed Stingray is a quick car even stock. The second race features a C6 Z06 that is also stated to be stock. The C6 Z06 only comes in manual so no transmission advantage here. It did not need a transmission advantage as the 7.0 liter 7000 rpm LS7 just pulls away. It also puts the C7 Stingray in context as the definitely is faster. So the Dinan tuned M4 gets beaten by both Corvettes. Considering the dyno results posted for the Dinan tune showing a gain of 20 wheel horsepower (but a nice torque jump) the results make sense. The M4 owner loses but can brag about his Dinan warranty. A DCT M4 no doubt would have done better likely opening up a lead in the lower gears but it is what it is.

    Awesome to see two exotic big boys go at it in a drag race. On paper the Aventador has the power advantage over the McLaren 650S with its 700 horsepower. The Aventador has a naturally aspirated 6.5 liter V12 powerplant compared to the McLaren's turbocharged 3.8 liter V8 unit. The McLaren 650S has 500 lb-ft of torque to the Aventador 508 lb-ft (on paper of course). The thing is the 650S hits its peak torque figures much sooner and has a fatter torque curve thanks to the turbos. This is one of those times where a peak measurement can be misleading. The 650S also is lighter than the Aventador by roughly 850 pounds. That is a huge difference and also keep in mind the McLaren is rear wheel drive to the Aventador all wheel drive. So what happens? The 650S gets a jump but it doesn't matter. It pulls away and covers the runway in 23.01 seconds compared to the Aventador 23.84. That is a significant difference and the 650S Spider was the quickest out of all the cars AutoWeek tested with the Aventador coming up behind it. The 650S power to weight and efficiency are just too much for even the Aventador to overcome.

    When i installed the jb4, i did a 25% e85 mix and the car ran great. After installing a new intake and charge pipe i tried 50%. Then car ran like crap. Kicked me to map 4, engine malfunction warning. Car drives great in normal driving, but horrible under WOT. So i figured too much e85. Drove car around and got fuel level down to almost a half tank and filled up with 93. Which shouldve put me back around 25% e85. Previously i was hitting 17psi. Now i can only get 12-14 out of it. Ive reset the map and moved the FOL down. Still wont make 17psi and acts funny under WOT. I can do the back end flash tomorrow but if it sounds like something else im all ears. What would make the car drop my boost level on map 5? Also a/f looks leaner than it was. Fuel trims maxing out so pulling boost?

    It feels like the US RS7 1/4 mile record only stood for a few minutes before being broken yet again. A few days ago AudiBoost posted an article on the quickest and fastest US RS7 at the time which ran 10.558 @ 132.56 in the 1/4 mile. The time and trap speed to beat now is 10.388 @ 133.54. The difference between this run and the previous run is that in addition to the APR Race gas software the RS7 in the video below also has a full exhaust system. Keep in mind this is still the APR Stage I software and a more aggressive software tune is on the way from APR (and others). At this rate we will see 9's out of the RS7 with bolt ons very soon.

    Take a deep breath and relax anyone. You do not want to get worked up like this fellow over C7 Z06 performance. Somebody finally took a new C7 Z06 to the dragstrip to set some independent numbers and the results are not exactly what you would call encouraging. Now, the driver did not do a good job that much is clear. A 2.19 60 foot is even remotely a good launch and he appears to bog a big off the line. Definitely needed some more revs. The shifting also left a bit to be desired as he turns a 120 mile per hour trap speed. This is lower than all the magazines and obviously not a great result. What this goes to show is just how much times can vary based on the driver and conditions. Someone else will take a C7 Z06 to the strip and run 10's at close to 130. Just because this car ran 120 does not mean they all do. Everyone calm down, especially Z06 fanboys. It is going to be ok, really.

    These Porsche 991 Turbo results come from our Middle Eastern friends over at PP-Performance. They flash tuned a 991 Turbo with their Stage I software and took it to the Yas Marina drag strip located in Abu Dhabi. The result is a very impressive low 10 second run. We wish we had the 60 foot figure but it appears there is something wrong with the lights or computer regarding the 60 foot time as it was not recorded. The 1/4 mile time was though and the car went 10.325 @ 135.229 miles per hour. Keep in mind this is the standard 991 Turbo and not the S. From the looks of it we will see 991 Turbo and Turbo S vehicles in the 9's shortly with bolt ons and race gas. Not all too different from what the PDK 997.2 cars are capable of.

Now i'm not genius, but to me its just a flash upgrade, but when I do that and reset the options in the Command Center, the car runs rough and flashes SES light 7 times at me. What am I doing wrong? an I going to just have to live with V4 and not be able to load V5? Any help is appreciated. 2007 335i e93 Vishnu Procede Rev3 (v4 currently)

    Great race video showing a bolt on Gen IV Viper with a tune and full exhaust putting out 583 rear wheel horsepower running everything in sight. This is a well done and crystal clear video showing the mods for each opponent and their approximate power level. Take notes people. Run 1 Heads/Cam A6 C7 Stingray 540 whp This one is over before it starts. The C7 likely was in the wrong gear or at least we hope he was in the wrong gear as the Vette gets destroyed. Run 2 stock GSXR-600: This race starts off well and then the Viper appears to let off. Missed shift maybe? Run 3 Paxton Supercharged Gen III Viper 798 whp: This one is rather hard to explain as it is neck and neck. The Gen III starts to pull but the bolt on Viper keeps pace. The Gen III sure does not look like it is pacing 798 wheel horsepower although with a blower it easily should be. Run 4 Shelby GT500 with Kenne Bell 2.8 liter 718 whp: Botched run although the Viper jumps out ahead. Run 5 stock C7 Z06 7-speed: That poor Z06. Run 6 C7 Z06 rematch: Same result. The Z06 gets creamed. Run 7 and 8 threeway Viper, Z06, and GT500 The Viper again starts to pull away and the Z06 is left in the dust by everyone. The GT500 misses a gear and the Viper wins another one. They line up for another run with the Viper again pulling away. It's starting to look like only the Viper owner can drive. Run 9 Shelby GT500 rematch: Much closer this time although there is noticeable wheelspin. The Viper still manages to edge up top. That is one impressive Gen IV and the guy who owns sure can drive it. He ran everyone and basically beat everyone. A well done video as well, great stuff.

    ESS-Tuning has been talking about their AMG M156 V8 supercharger kit for years now with nothing to show for it. Well, they at least have a picture now to show off their supercharger mounted on an M156 and state that it should be 'coming soon' which translates to still in development. What are the specs? We do not know. What is the expected output? We do not know. What is the price? We do not know. All we know is that they are still working on it. The M156 supercharger market pretty much belongs to Weistec. ESS-Tuning wants to take some of that money they made from using the forums to push M3 S65 kits and expand into other areas. This is likely way too little way too late. It also likely is not a 3.0 liter twin screw setup which means for those that want maximum performance better and proven options are already on the market.

    Cadillac has leaked out that they will debut the next generation CTS-V at the Detroit Auto Show taking place next month or more accurately in just over three weeks. Considering how powerful Cadillac's European competition is they need to pack some serious heat. They intend to as the C7 Z06 LT4 6.2 liter supercharged direct injection V8 is expected under the hood. This raises the question as to whether the CTS-V will get the exact same LT4 or if there will be changes much like the previous generation CTS-V saw to its LSA V8 compared to the LS9 it was based on which saw use in the ZR-1 Corvette. Let's think positively for a moment that the CTS-V will not be detuned. That means 587 rear wheel horsepower for the CTS-V or in other words more than any of its competition. It will likely be mated to the 8L90 automatic transmission which offers incredibly quick gear changes meaning GM is likely to have the fastest luxury performance sedan in the world if they manage to keep the weight from ballooning. We will know more next month but let's hope GM gives the CTS-V the LT4 without any changes and if they do make any changes they only do so to give it more, not less, power and torque.

    I purchased myself a new Mfactory LSD for my bolted 335 MT. I have access to a full lift and any tool I could need so I'm thinking of doing the install myself. It seems super straight forward... I've done some big jobs like turbo swaps on my old 1.8t and clutches here and there but never any major differential mods. I found a few DIYs on other forums but we all know the technical folks lurk the bimmerboost waters and I wanted to get some input from anyone with experience installing a torsen LSD in our cars.
