    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 Dinanฎ 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.

    Pretty certain this is my next computer. I need something with a bit more power than my laptop plus I want to run 3 x 28+ inch 4K screens. Sick design, watercooled, etc.:

    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

    Now we're talking! The main problem BimmerBoost has with the i8 is that BMW went overboard in the efficiency department for a two-seat sports car (technically 2+2 but try to sit in the back) that costs over $130k. The i8 performs well and makes efficient use of its 357 horsepower and 420 lb-ft of torque. That is decent power but it just not cut it in the golden age of horsepower. Especially considering the ~3400 pound carbon tub i8 chassis is simply begging for more. Who is buying cars approaching $150k with options to save a few MPG anyway? The i8 potentially is capable of so much more. Its 1.5 liter three-cylinder turbo engine only produces 231 horsepower. Good for a 1.5 liter motor of course but imagine if BMW used their S55B30 inline-6 engine from the M3/M4 instead? Automobile reports that may be a possibility. The other possibility is a 320 horsepower 2.0 liter four-cylinder and considering that BMW does not have one of these sitting around the M division would have to develop one likely starting with the N20 engine as a base. Ok, fine, even a 320 horsepower 2.0 liter four-cylinder massaged by M is better than this 1.5 liter three-cylinder nonsense. The best bet and what BMW should do is the S55B30 3.0 liter inline-6 giving the car an underrated 554 horsepower and 590 lb-ft of torque. That is of course assuming no changes to the electric drivetrain. Really BMW should use a twin turbo S85 V10 for the gasoline motor but now we're dreaming and we'll be content with an i8 that finally has the performance to back up the looks. The four-cylinder although better than the three-cylinder just is not good enough for a proper M1 successor and a car to honor a hundred years of BMW. This is a one time one shot thing. Go big or go home. It's now or never. Ulrich Kranz who is the BMW i Senior Vice president is apparently pushing for this hotter i8 which will be called an i8S instead of an i8M. Keep in mind last year BMW stated i and M need to remain separate which is a steaming hot pile of you know what. Look, this M version of the i8 or higher performance i8 or whatever you want to call it has been reported off and on for years now. Automobile Magazine says it is coming but we have heard this before only for reports weeks later to state the opposite. Enough already. Someone at BMW confirm this thing and let BMW M go to town on the i8. In April of this year BimmerBoost made the case for a high performance i8. The conclusion is the same as before: It is time to build the Ultimate Driving Machine. It is now or never. Either you produce an enthusiast car or just admit you no longer build 'only one thing.' Build the i8 M or M1 as you have put your hardcore and loyal fans through enough and yet we are still here. If you do not, we won't be for much longer. Source
