    This will be something we will see more and more of over the coming years and one of the more interesting battles in the BMW performance scene in the opinion of BimmerBoost. We have BMW's newest turbocharged M car going against the M car it replaced. As you well know the E90 M3 comes with a naturally aspirated S65 4.0 liter V8 that revs to 8400 rpm from the factory. It makes much less power (roughly 70 wheel horsepower) than the turbocharged 3.0 liter S55 direct injected inline-6 engine in the new F80 M3. It becomes a complete mismatch when the S55 gets a tune such as the JB4 on this particular car. The thing is, what happens when you boost the older M car? This E90 M3 gets boost for its S65 V8 courtesy of an ESS VT2-625 supercharger kit. The high revving naturally aspirated V8 responds quite well generating in the area of 600 wheel horsepower depending on the supporting modifications, fuel, and tune. It is making this horsepower with far less torque than the S55 inline-6 however. This is a race won by top end power and with a centrifugal blower top end power is exactly what the E90 M3 offers. The F80 M3 comparatively offers much more low end torque and has a curve shifted far more to the left than to the right. It is two different M engine philosophies at work here and both are effective. The supercharged E90 M3 wins this round but as tunes and supporting mods evolve for the F80 M3 it will compete with stock internal supercharged E90 M3's on its stock turbochargers. It will also be interesting how it does against the E90 M3 with turbos instead of a centrifugal supercharger. The E90 M3 only has in the 370 lb-ft of peak wheel torque range compared to the 550+ wheel torque this JB4 tuned F80 M3 is capable of generating. Yet it is where that torque is generated that determines the outcome here. Top end horsepower rules this race. No doubt enthusiasts will debate the approaches here. Both are viable. However, more displacement and higher revs with a torque curve that continues to increase toward redline is hard to beat in a race like this. The older M cars are hardly obsolete. They're incredible. E90 M3 - ESS VT2-625 SC, Akra GT4, 100/91 oct blend F80 M3 - Catless downpipes, full Akra Exhaust, JB4 Map 7, 100/91 oct blend P.S. Iphone videos of races like this make us cry.

    Despite our best efforts to get our shop car running properly in time for the event we decided not to run the car at all this past weekend. The #2 cylinder is leaking down over 25% and we will be putting another stock motor in shortly to continue development so we just cruised down to Coalinga to spectate. Here are some photos from the event. Hope you all have a great week! It will be a very busy and exciting one for us as we continue to assemble / ship the Stage 2+ N54 turbos and are awaiting testing of the world's first S55 turbo upgrade :music-rockout:.

    Seeing what the big magazines pick as their favorite driver's car is always interesting. Last month MotorTrend took their shot at it with a ten car field and settled on the Chevrolet Camaro Z28 as the best driver's car in all the land. Now it is time to get a British perspective on the matter. Autocar decided on a 12 car field. They usually field 10 cars but made an exception in 2014. There are some big name omissions one of which is the Lamborghini Huracan as Lamborghini declined their invitation (the raging bull is afraid?) and the Z28 is absent. Autocar's 12 car field is as follows and ordered by laptime: 1. Ariel Atom 3.5R – 1min 10.7sec 2. Ferrari 458 Speciale – 1min 11.9sec 3. McLaren 650S – 1min 12.9sec 4. Porsche 911 GT3 – 1min 13.1sec 5. Chevrolet Corvette Stingray – 1min 14.3sec 6. Jaguar F-type R coupé – 1min 14.3sec 7. Vauxhall VXR8 GTS – 1min 14.9sec 8. BMW M4 – 1min 16.8sec 9. Porsche Cayman GTS – 1min 17.4sec 10. Alfa Romeo 4C – 1min 17.7sec 11. Renault Mégane RS 275 Trophy – 1min 19.4sec 12. BMW i8 – 1min 19.4sec This is how Autocar ended up scoring the cars as far as driving pleasure: 1. Ferrari 458 Speciale – 16 points 2. Ariel Atom 3.5R – 19 3. Porsche 911 GT3 – 27 4. Porsche Cayman GTS – 33 5. McLaren 650S – 39 6. Chevrolet Corvette Stingray – 43 7. Renault Mégane RS 275 Trophy 54 8. BMW i8 – 64 9. BMW M4 – 78 9. Vauxhall VXR8 GTS – 78 11. Jaguar F-type R coupé – 80 12. Alfa Romeo 4C – 93 The Ferrari 458 Speciale takes the victory over the Ariel Atom although the Atom is really nothing more than a street legal go-kart. The 458 reigns supreme but it is interesting to note some of the comments by Autocar on the vehicles. The M4 is said to be somewhat of a one trick pony always wanting to go sideways. Yes, the M3/M4 are more about muscle than finesse now. The i8 is said not to be a sports car and its handling changes based on the charge of the batteries. It is said to be better on the road and out of character in the competition which is a shame. The Corvette feels like it got a bit robbed here. A judge scored it as high as second yet it finishes in 6th place? Another judge stated out of all the cars the Corvette is the one he would want to race on the track. So again, what is with the sixth place finish with all the glowing praise? It is surprising the McLaren 650S gets beaten by a full second by the Ferrari. Especially considering its twin turbo V8 is boosted to 650 horsepower now. The Castle Combe track seems a bit short but Autocar feels it is a good test and a 'fast' track. The 458 Speciale is Britain's best driver's car of 2014 according to Autocar. The full video breakdown is below:

    10's are just around the corner for the S55 powerlpant people and that is not surprising. This is the quickest F82 M4 and S55 powered car in the world currently thanks to its 11.18 @ 123.56 pass. TPG Tuning is claiming this is the fastest M4 in the world although an F80 M3 has gone 126 in the 1/4 mile. So, technically, it is the fastest F82 M4 for now but not the fastest S55 powered car as that belongs to an F80 M3. Additionally, TPG Tuning is taking a lot of credit for this while forgetting an F80 M3 has gone faster and I think we all know it is really the JB4 tune from BMS doing the majority of the work here. What readers really should take away is that 10's are coming for the F82 M4 and F80 M3 with the right combination of modifications, traction, conditions, and someone brave enough to use launch control to get out of the hole. The 1.6596 60 foot certainly is impressive as it is without launch control. Modifications are: BMS JB4 with a custom map Race Fuel Hoosier Drag radials

    The BMW S1000RR is an absurdly fast bike in stock form capable of trapping in the tall 140's. Beating one is a very tall order for any street car in stock form let alone tuned. This S1000RR is tuned though by BrenTuning and also features a full Akrapovic exhaust. That should easily push it well into the 150+ trap speed range in the 1/4 mile. Procharged Vettes are of course capable of hitting those trap speeds but require a built motor and a ton of boost. We do not know the specs on this C6 only that based on the result the blower needs to move quite a bit air if the owner wants to run with this bike.

    Introducing the new GTRS4 BMW F82 M4 widebody kit from Vorsteiner. The kit is similar in style to their GTRS3 widebody kit most have seen for the E92 M3. Vorsteiner gives the F82 M4 very aggressive wide rear fenders as they did with the E92 M3 which certainly makes the car look much more aggressive. The photos certainly looks great and the design is solid. BimmerBoost will give impressions on how the kit looks (and the fitment) in person at the SEMA show in Las Vegas next week where the kit will makes its official debut.

    GM had a great showing at SEMA with plenty of exciting cars. What stood out though was this beautiful monster. The upcoming 2015 Chevrolet Z06 convertible is a work of art. This particular example has the gorgeous Laguna Blue paint as well as the optional Z07 package. Those are carbon ceramic brakes you see as well as carbon fiber aerodynamic pieces designed for increased downforce on the track. This is one convertible that will be right at home on the roadcourse. In person the Z06 definitely looks more aggressive than the standard Stingray and the wider hips also add sexiness. The C7 design is simply beautiful and the Z06 takes it to the next level. You already know all about the 650 horsepower LT4 supercharged V8 as well as the 8L90 8-speed automatic that is available as an option. GM hit it out of the park with this car especially if the performance is as good as the styling (which it will be).

    Interesting tune only matchup here of the new turbocharged F80 M3 and F82 M3. Both cars of course share the same 3.0 liter direct injected S55 inline-6 turbo motor. The only modification to each car is a tune with the camera car being the F80 M3 with the BMS JB4 tune. The BMS JB4 car is running on Map 7. The ECU Tuning Group car has their tuning solution which they claim adds 89 horsepower and 96 lb-ft of torque. BimmerBoost has not seen any dyno sheets or timeslips backing up their claims as is the general trend for ECU Tuning Group products. BimmerBoost has seen dyno sheets for the BMS JB4 tuned S55 motors and they are over 500 wheel horsepower. Dynosheets are one thing and putting that power down in practice is another. In practice, the JB4 car simply pulls away (although it does start early). One sided race:

    At the SEMA show this year the new F82 M4 was all over the place. Two major widebody kit options made their debut with the LB Performance widebody and the Vorsteiner widebody. The LB Performance styling should be familiar to those who have seen the previous E92 M3 version. The styling is much more over the top and Asian inspired than the refined European touch one would expect on a BMW. It definitely is attention grabbing and the kit offers better fitment than several E92 M3 LB Performance kits BimmerBoost has sampled. This fits and looks better but there still are gaps and fitment issues. As far the styling is concerned it definitely is attention grabbing. The thing is, this widebody kit is all about form over function. It is not made so you can fit wider wheels and tires specifically for racing. Just based on looking at the pieces up close themselves there does not seem to be any aerodynamic testing to inspire the design based on performance. This is all about looks folks and this kit certainly is going to increase drag and maybe not even proportionally. Out of the two M4's fitted with the LB Performance kit at the SEMA show BimmerBoost found the white one to have the better execution. If one wants to hide the gaps and rivets making the kit appear to flow together better a dark color is probably the best choice. Is it attention grabbing? Yes. Is it different? Well, this style is starting to get a bit played out. Does it belong on a BMW? That is up to to you decide.

    The official debut for the 2015 Shelby GT350 is tomorrow at the Los Angeles International Auto Show. Ford fortunately is giving an online sneak peak for those who will not be in attendance. The new track star of the Mustang lineup is everything is was hyped up to be and then some. The heart of the car will be a flat-plane crank V8 as rumored displacing 5.2 liters. Exact output figures will not be available until tomorrow but expect over 500 horsepower and 400 lb-ft of torque. Yes, that means this motor will be very close to 100 horsepower per liter possibly even exceeding it. A Ferrari style V8 with American displacement? Talk about a match made in heaven. This car is all about the track though and not just muscle. Ford worked on making the chassis much stiffer and they succeeded. The new chassis is over 28% stiffer than the previous model. The GT350 also offers a wider front track and a strut tower brace. Lightweight wheels are specced to reduce as much unsprung weight as possible. The lightweight 19 inch wheels are 10.5 inches wide up front and 11.0 inches wide in the rear wearing Michelin Pilot Super Sport rubber. The front rotors are huge 394mm units and 380mm are used in the rear. The dampers are continually adjustable MagneRide units. Sensors monitor each corner independently and can make adjustment every 10 milliseconds for optimum handling. More details will come tomorrow but enjoy what is the most powerful naturally aspirated V8 Ford has ever produced and the most track capable Mustang yet: SHELBY GT350 MUSTANG: THE LEGEND RETURNS All-new Shelby® GT350 Mustang is a thoroughbred capable of tackling the world’s most challenging roads and racetracks GT350 is powered by a unique, high-revving flat-plane crankshaft 5.2-liter V8 engine that will produce more than 500 horsepower – the most powerful naturally aspirated Ford production engine ever Advanced materials, MagneRide dampers, aggressive brakes and finely tuned aerodynamics push the performance of Mustang to previously unmatched levels The original Shelby GT350 introduced in 1965 established Mustang’s performance credentials. The all-new Shelby GT350 Mustang, featuring the most powerful naturally aspirated Ford production engine ever, is a world-class performance vehicle, designed to tackle the planet’s most challenging roads – an all-day track car that’s also street legal. The new GT350 builds on Carroll Shelby’s original idea – transforming a great every-day car into a dominant road racer – by taking advantage of a dramatically improved sixth-generation Mustang to create a truly special driving experience. Driving enthusiasts behind the wheel of a Shelby GT350 can expect to be treated to the most balanced, nimble and exhilarating production Mustang yet. Ford engineers took an innovative approach with GT350. Rather than develop individual systems to perform well independently, every component and shape is optimized to work in concert; balance is the key. While paying rigorous attention to detail, the team pushed the envelope with cutting-edge materials and technologies. “When we started working on this car, we wanted to build the best possible Mustang for the places we most love to drive – challenging back roads with a variety of corners and elevation changes – and the track on weekends,” said Raj Nair, Ford group vice president, Global Product Development. “Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant – nimble, precise handling and massive stopping power.” Track-tuned driveline Early in development of the GT350, it was decided a high-revving, naturally aspirated V8 engine would best suit a track-focused Mustang. “The final product is essentially an all-new powerplant unique to GT350 – and one that takes true advantage of the new chassis dynamics of the Mustang platform,” said Jamal Hameedi, chief engineer, Ford Global Performance Vehicles. The new 5.2-liter engine is the first-ever production V8 from Ford with a flat-plane crankshaft, an architecture typically found only in racing applications or exotic European sports cars. Unlike a traditional V8, where the connecting rods are attached to the crankshaft at 90-degree intervals, this design evenly spaces all crank pins at 180-degree intervals. The 180-degree, flat-plane layout permits a cylinder firing order that alternates between cylinder banks, reducing the overlap of exhaust pressure pulses. When combined with cylinder-head and valvetrain advancements, this permits better cylinder breathing, further extending the performance envelope of the V8. The result is the most powerful naturally aspirated production Ford engine ever, at more than 500 horsepower, with a torque peak above 400 lb.-ft. The track capability is enhanced by the output characteristics of the engine – the 5.2-liter V8 features an exceptionally broad torque curve. Combined with its high-revving ability, the flat-plane 5.2-liter V8 gives drivers an enormous amount of performance and flexibility within each gear of the lightweight six-speed manual transmission. A standard Ford-tuned Torsen limited-slip differential optimizes cornering grip and straight-line traction. “Make no mistake, this is an American interpretation of a flat-plane crankshaft V8, and the 5.2-liter produces a distinctive, throaty howl from its four exhaust tips,” said Hameedi. Balanced dynamics The new Mustang platform is the strongest in the history of the brand, with torsional stiffness increased 28 percent over the previous model. That stiff structure ensures the suspension geometry remains consistent, even under hard driving on back roads and tracks. Front stiffness is further improved on GT350 with a cutting-edge injection-molded carbon fiber composite grille opening and optional lightweight tower-to-tower brace. The front track has been increased while spring rates and bushings have been recalibrated all around, with ride height reduced compared to Mustang GT. For optimum handling, the wheels need to respond quickly to the contours of the road and driver input. Reducing unsprung mass is key to improving that response, but a balance must be struck between taking mass out of a suspension and delivering truly capable braking performance. Due to the significant speeds the car can develop, GT350 features the most track-credible brake system ever offered on a Ford vehicle in terms of absolute stopping power, fade resistance and brake pedal feel. The brakes are two-piece cross-drilled iron discs mounted to aluminum hats. At the front are massive 394-millimeter rotors clamped by Brembo six-piston fixed calipers with integrated caliper bridges, while 380-millimeter rotors at the rear utilize four-piston calipers. GT350 makes use of extra-stiff 19-inch aluminum-alloy wheels – 10.5 inches wide in front, 11.0 inches in the rear – clad in state-of-the-art Michelin Pilot Super Sport tires with GT350-specific sidewall construction, tread face and compound. The custom tires are designed to deliver maximum grip on the road or at the track. Ultra-quick responsiveness to changing conditions is provided by the first-ever Ford application of continuously controlled MagneRide dampers. The dampers are filled with a hydraulic fluid impregnated with iron particles; when an electric current is passed through the fluid, a near-instant adjustment of the suspension performance can be made. With wheel position sensors monitoring motion thousands of times per second combined with other vehicle data, changes can be made to each corner independently every 10 milliseconds for optimum handling performance. This is a system designed not just to make the car handle better but to instill greater confidence in even the best driver. Obsession to detail “Everything we changed on GT350 is purely functional-driven design, with the goal of improving the overall performance of the car,” said Chris Svensson, Ford design director, The Americas. “We optimized the aero shape of the car, and then fine-tuned what was left to increase downforce and cooling airflow.” All bodywork from the windshield forward is unique to this high-performance model and up to two inches lower than Mustang GT. The new aluminum hood has been lowered and sloped, compared to the base Mustang, tightly wrapped around the engine for the smallest possible aerodynamic signature. Front and rear aero elements have been balanced to work together on the track. The fascia has been resculpted to provide the aggressive lower front splitter with maximum pressure and a ducted belly pan delivers significant downforce. The hood outlet acts as a heat extractor while also reducing underhood lift at high speed. At the rear, much of the engineering was focused on creating an aggressive functional diffuser doing double duty to increase downforce and provide cooling air to the optional differential cooler, and a subtle lip spoiler across the trailing edge of the decklid increases downforce without adding excess drag. The athletic stance of the all-new Mustang is further accentuated with recontoured aluminum front fenders to accommodate the wider front track and wider wheel arches. Front fender vents work with vented inner fenders to draw out turbulent air in the wheel wells and smoothly direct it down the side of the car. The forward-angled grille is designed with individual openings to draw air through the radiator, high-pressure engine air intake, cooling ducts for the front brakes and, optional with the Track Pack, an engine oil cooler and a transmission cooler. Focus-driven cockpit changes Like everything else about GT350, the interior has been optimized for driving, beginning with the specially designed Recaro sport seats with a unique cloth. Hundreds of hours and many prototypes went into a seat that is both comfortable in daily driving and capable on the track. A flat-bottom steering wheel makes it easier for the driver to get in and out, and is more ergonomic on the racetrack. Gauges are upgraded to reflect the enormous performance capability of the car. Chrome and bright finishes have been reduced or eliminated to prevent sun glare that may distract the driver. The advanced technology inherent to Mustang has been deployed for duty in the Shelby GT350. An all-new integrated driver control system allows selection of five unique modes that tailor ABS, stability control, traction control, steering effort, throttle mapping, MagneRide tuning and exhaust settings, depending on driver preference, to achieve maximum performance. Drivers are invited to test them all. Drivers interested in comfort, convenience and entertainment upgrades may select the Tech Pack, which includes power, leather-trimmed seats; Shaker Audio; 8-inch MyFord Touch® LCD touch screen; and dual zone electronic temperature control, to name a few features. “We took the best Ford Mustang yet and massaged every aspect of the car that affects the performance driving experience,” said Hameedi. “We tested endlessly on the most challenging roads and tracks in the world, and we believe serious drivers will love the Shelby GT350 Mustang.”

    So this morning I was on my way to class when this kid in a scion tc past by me. He apparently hit a patch of black ice and lost control of his vehicle. I saw the whole thing coming, but there was nothing I could do to save my car, he smacked into me and sent us both flying off into a ditch on the side of the highway. I will find out for sure if the car is totaled or not in the next few days, but after talking to my body shop (whom I have a great relationship with) they are confident it will be totaled. This really sucks because my car was finally coming together I just installed bc racing coilovers a few weeks ago along with all the other mods done to the car. Thankfully I was not at fault so hopefully everything will be covered by his insurance, but this still sucks:( I really don't know what car to get next... I loved my m3, but I don't want to get another one while I am still in college, this whole thing just sucks I worked hard to get this car and get it where is was and now all of it is gone.
