    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.

    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:.

    Hello, This is one of my first threads over here at BimmerBoost. I had been visiting tacopost 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 El Cholo taco solution for proper satisfaction of human hunger. I have previously eaten many tacos outfitted with other ingredients and I was never close to satisfied. It just didn't feel like the tacos I know and love. There's this taco place I'm not affiliated with AT ALL called El Cholo that just has awesome tacos. Seriously, they are great! They also have Taco Tuesday with $2 taco deals and margarita deals that you wouldn't believe. They also treat me well and look at these tacos: The facility is pretty nice too: They even have enchiladas if you don't want tacos! I'm just a taco enthusiast trying to share my tacos enthusiasm with fellow taco enthusiasts. Please pay no attention to my e-mail address being sticky@elcholo.com. I hope you all have some yummy yummy tacos!

    Dinan launched a new BMW club racing engine based on the S65 V8 out of the E9X M3 models. Dinan increases the bore and stroke to increase displacement from 4.0 liters to 4.6 liters. Just as with Dinan's standard S65 stroker motor the bore and stroke goes to 94mm x 83mm. Now might be a good time to bring up an old BimmerBoost S65 V8 stroker comparison article from 2010. This was the statement BimmerBoost made about the potential of the S65 stroker motors: 'By shifting the power band to the left the torque curve falls off faster not allowing the stroker to show full potential with the stock cam profile that was not designed for it. Neither Dinan or RDsport address the cams.' Well come 2014 Dinan does address the cams and that explains why the club racing S65 engine makes an additional 80 horsepower over the standard stroker. Dinan is essentially giving the motor a dry sump, adding Schrick cams, and a more aggressive tune. Now, $39,999.00 is a lot of money for a stroked S65 with a dry sump oiling system one can get from VAC and Schrick cams. Especially considering the engine requires a standalone engine control system that is not included in the price. That means this engine gets up close to $50k when all is said and done. Now, there is no point to have another discussion on Dinan pricing as Dinan is well aware of his own pricing. BimmerBoost could build this motor for almost half the price though and have it tuned on the stock DME meaning you could use it in a street car if you wanted to without the need for a standalone ECU. What is really nice to see is more aggressive cams paired with the stroker motor. So Dinan's 580 horsepower quoted output is about right considering an RD Sport stroker without the aftermarket cams hits 441 wheel horsepower (Dinan in customary fashion does not provide a dynograph at the wheels): One could expect in the ~500 whp range depending on the tune and fuel quality in naturally aspirated form from a stroked S65 V8 paired with some aggressive cams. That certainly would be a lot of fun on the racetrack which is obviously what this motor is built for. Dinan: For those seeking the ultimate high performance driving experience, Dinan has once again redefined M3 performance with a bored and stroked 4.6 liter version of BMW's V-8 engine complete with a dry sump lubrication system and solid lifter camshafts. The engine produces 580 horsepower at 8200 RPM along with increased torque of 390 lb-ft at 6900 RPM. The engine is supplied as an assembled long-block, fully prepared.. Due to the engine’s high state of tune, a Bosch or Motec stand-alone engine management system is required to run this breed of S65 engine. Dinan's 35 years of BMW tuning and racing experience ensure that the engines will perform for lasting trouble free driving excitement. Much of the technology that has made Dinan's Grand-Am Daytona Prototype engines both competitive and reliable has carried over to the 4.6 Liter V-8 engine program for street and amateur racing use, ensuring that the engines produce great power along with race-proven durability Features and Specification of the Dinan® S65 4.6L Club Racing Engine: + 4.6L long block (bore = 94mm; stroke = 83mm; compression ratio = 12:1) + Peak Power: 580 HP @ 8200 RPM and 390 ft-lbs @ 6900 RPM + High lift camshafts with solid lifters + Dry Sump lubrication system + Dinan proprietary billet crankshaft + Dinan proprietary lightweight forged pistons + Dinan proprietary light-weight connecting rods + Balanced, blueprinted and dynoed + Dinan serial numbered block + NO DINAN WARRANTY + RACING ONLY PART + NOT EMISSIONS LEGAL Core Program: Engines are a part of the CORE program we utilize at Dinan so you will be charged an additional fee on top of MSRP initially. This fee will then be refunded to you once your qualifying engine core has been received at Dinan. This ensures we have a continuous stream of product for rebuilding purposes and the lowest possible price to the consumer.

    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

    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:

    We are here because we are car enthusiasts. We like cars. Some of us maybe more than others or some maybe too much for our own good but one thing we all have in common is an appreciation for cars. That is why we all understand the actions this man takes to perform a save on this car. Yes, he makes a mistake by leaving the car in neutral. He quickly realizes this mistake and runs after the car as it rolls back managing to close the door just in time before it hit the garage. He then quickly jumps in over the door and brings the car safely to a stop (using his hand on the brake pedal mind you) before it hits anything. He is fortunate the top was down or this could have ended badly. He is also fortunate the car was not turning back at a greater angle as he could have been pinned against the edge of the garage. It certainly would be interesting to know if it is his car or if it belongs to someone else. Whether you like classic Mustangs, European cars, Japanese cars, whatever, you will be able to appreciate this save as a car enthusiast.

    This will hardly be the last battle of boosted E46 M3 S54 motors and boosted E9X M3 S65 motors. This battle is just heating up but here is an interesting race pitting an Active Autowerke Generation 2 Level III supercharged E90 M3 against a Maximum PSI Stage II supercharged E46 M3. Both cars have 6-speed manual transmissions so this is not a race won by a transmission advantage. The S54 inline-6 in the E46 M3 and the S65 V8 in the E90 M3 are both on stock internals and factory compression. The E46 M3 is a Maximum PSI Stage II turbo which we have seen hit 697 wheel horsepower. Additionally, the kit has gone 10.8 @ 131 in the 1/4 mile. The car belongs to our friend over at MPACT. Now from what BimmerBoost has been told MS109 fuel was not available for this run so boost is closer to the Stage I Maximum PSI kit and considering the result that makes sense. The E92 M3 has the Active Autowerke Gen 2 Level III supercharger kit which includes methanol injection and has put down in the 590 wheel horsepower range with simply the best looking torque curve in the industry. Now this kit was tuned by Frank Smith at TTFS so it is safe to say it is making a bit more than the base AA tune. The video quality is not the best partially due to the night time run but it is easy to see what happens. The E46 M3 hits a bit of lag and the E92 M3 pulls on the shift. It then continues a steady pull and the run just really isn't close. The E46 M3 of course would be stronger with more boost but the same could be said about the S65 as well. This will not be the last battle between the E46 and E9X. That fight is about to become full scale war with more built motor S65's hitting the streets.

    This is a similar question to what BimmerBoost raised last year regarding an M2 model. A ton of speculation took place from the various culprits on the 2015 F87 M2 this year and one site even claimed to definitively know the M2 would have a more aggressively tuned N55 from the M235i. Our position was (and remains) that nobody knows what the hell they are talking about and that they are simply guessing to get attention. CAR is claiming to definitively know what the specifications for the M2 are and here is their take. CAR states the F87 M2 will arrive in 2015 and offer 369 horsepower and and 384 lb-ft of torque featuring a detuned S55 inline-6 borrowed from the F80/F82 M3 and M4. Ok, fine, that certainly is a possibility. CAR does not state how the engine will be detuned, who at BMW stated this is the engine if anyone even did, or any real solid info on the motor. Is it just a software detune? Is BMW mating the motor to a DCT in the 2-Series finally? Will the motor get a different turbocharger or any physical hardware differences? You would think someone who supposedly has access to an inside source at BMW would ask these questions. If the M2 gets a detuned S55 and it is only detuned through software we can declare right now the M2 is the greatest tuning value in the history of the BMW lineup considering how underrated the S55 engine is and what it gains from basic tuning. If it is detuned through hardware means to protect the M3/M4 this is not a big deal anyway as on paper the M3/M4 and the M2 will have the same potential. If it features an N55 like the M235i as some reported then it does not have a real motor and BMW is really getting out of control with their cost cutting and their watering down of the M brand. All CAR has done is create a bunch of hype. That sells magazines. Good for them but they aren't getting our money. Source

    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.

    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:
