    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.

    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.

    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.

    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.

    Hi Guys, I've been a long-time lurker around here, but I've got a problem and I need some help! I bought a BT cable to re-flash my DME to a suitable Pump gas flash, however it says I've got an 0IF80S bin when I read the DME. I've looked at the both the IJE0S and I8A0S files and XDF's provided by Terry in tuner pro and the data doesnt match up to my existing bin. I'm not sure what to do, as the only option I can see is manually creating a map using bits and pieces for the OFT but that's not going to work with the JB4 correctly. Has anyone encountered this before and is there a work around? Some details of my car; May 2008 N54 335i, UK spec car. Thanks James

    The C6 ZR1 and C7 Z06 have engines have some similarities. They both have the same 6.2 liter displacement and both are supercharged V8 engines. The similarities pretty much end there though as they are two different generations of GM supercharged V8's. The LT4 of course incorporates direct injection which allows higher compression at 10.0:1 compared to the 9.1:1 of the LS9. The LT4 also has a smaller 1.7 liter supercharged compared to the LS9 2.3 liter unit. It is quite a bit smaller but also 20 pounds lighter. They both have the same 6600 rpm redline. Let's break down each motor with GM's own details: LT4 6.2L supercharged engine specifications Displacement (cu in / cc): 376 / 6162 Bore & stroke (in / mm): 4.06 x 3.62 / 103.25 x 92 Block material: cast aluminum Crankshaft: 1538MV steel Connecting rod (in / mm): 6.125 / 155.5 powder-metal steel Piston: forged aluminum with internal ribs; flat-top crown Cylinder head material: A356-T6 rotocast aluminum Induction system: 1.7L supercharger 9.4 psi / 0.65 bar max boost Valvetrain: overhead valve, two valves per cylinder Valve type (intake / exhaust): 54mm solid titanium / 40.4mm sodium-filled Camshaft type: hydraulic roller Intake valve lift (in / mm): 0.492 / 12.5 Exhaust valve lift (in / mm): 0.551 / 14 Duration @ 0.050-in. tappet lift (crank angle degrees, intake / exhaust): 189 / 223 Camshaft lobe separation angle (degrees: 120 Fuel delivery: direct injection Fuel injectors: 25cc/second (1.5L/min) Engine-driven fuel pump (psi / MPa): 2900 / 20 Lubrication system: dry sump, incl. oil-spray piston cooling Compression ratio: 10:1 Horsepower (hp / kW @ rpm): 650 / 485 @ 6400 SAE certified Torque (lb-ft / Nm @ rpm): 650/ 881 @ 3600 SAE certified Max. engine speed (rpm): 6600 Recommended fuel: premium required LS9 6.2L supercharged engine specifications The LT4 is rather at 650 horsepower and 650 lb-ft of torque despite the smaller blower. The LS9 is rated at 638 horsepower and 604 lb-ft of torque. The difference between the two in practice at the wheels is even greater than the crank ratings on paper: 49 wheel horsepower and 84 lb-ft of torque at the wheels difference in favor of the LT4 over the LS9. These numbers really make one wonder why the C7 Z06 is not putting up better performance numbers.

    A Ferrari may look like a work of art on the outside but you might be surprised as to the quality of the components that make production. Ferrari has some of the best engines in the world but their production exhaust systems at least on the base cars leave a lot to be desired. This what the full Fabspeed header back F430 exhaust system looks like: Absolutely gorgeous, right? Now here is what a stock Ferrari F430 manifold looks like in comparison to the Fabspeed piece: A night and day difference? Yep. The difference is not just in looks and sound either. The full Fabspeed exhaust package that includes catalytic converters with an ECU tune gains 51 wheel horsepower and 30 lb-ft of wheel torque on the standard F430. Some people think Ferrari's are perfect from the factory. Well, we hate to break the facade but they are not. Even a Ferrari can be improved upon and significantly at that.

    If you are an avid reader of this network (and you should be) then you remember an article from a few months back of a 991 Turbo S versus a Lamborghini Aventador in a standing kilometer drag race. The 991 Turbo S won the drag race but the Aventador had the higher trap speeds meaning it was pulling harder up top. That standing kilometer result means that from a roll the Aventador should win against a stock 991 Turbo S. Well, last month we happened to see an Aventador go up against two 991 Turbo S models. The Aventador beats both of the 991 Turbos. So what happens if the 991 Turbo S gets a tune and full exhaust? What you see below. From both a stop and a roll the 991 Turbo S pulls the Aventador and it does so easily. The run from a stop does not feature a launch from either car though and they simply mash the gas. Despite having 'only' a 3.8 liter flat-6 engine versus the Aventador 700 horsepower 6.5 liter V12 the Porsche's turbochargers give it the advantage. It certainly does not hurt it weighs roughly 500 pounds less and has a dual clutch transmission.

    It is no secret we are fans of the Hellcat V8. How can you not be? Underrated 707 horsepower? Twin screw 2.4 liter blower? Forged internals from the factory? Yes to all of that! Now the question is what other cars will the Chrysler group shove the Hellcat supercharged V8 into? Jeep ruled out a Hellcat Cherokee for 2015. That does not mean we will not see one eventually though. Any holdup is likely due to trying to figure out how to get the transmission and all wheel drive drivetrain to hold the massive torque. Considering how big of a hit the Hellcat V8 is it only makes sense to stuff into a Cherokee. Maybe even a RAM as well if we really get lucky.
