    Rebellion Automotive is based out of the UK and The Turbo Engineers home is in Germany. It makes sense for these two to link up to provide a big turbo upgrade for the M133 motor. Rebellion Automotive already offers their Stage II turbo upgrade which utilizes a modified OEM housing. What does this upgrade entail? We don't really know as only this teaser photo stating TTE460-R is provided. We do know that Rebellion is now moving to flash tuning. Their previous turbo upgrade used their piggyback box but now with greater ECU control it looks like some more serious turbo upgrades are possible. The Turbo Engineers does some great work so we know the hardware side will be solid. Just take a look at their Audi 2.5 TFSI turbo upgrade work. If the 460 in the TTE upgrade is anything to go by it looks like 460 wheel horsepower should be the target here considering the Stage II Rebellion upgrade that we assume TTE did offers 401 wheel horsepower. Either way bigger turbos are coming to the M133 platform from multiple sources. The more competition, the better for AMG enthusiasts.

    The network has become increasingly skeptical of 1/4 mile times coming out of the Middle East and specifically the Yas Marina drag strip located in Abu Dhabi in the UAE. Recently, a very fast run from a C63 showing an impossible 60 foot time raised eyebrows and Middle Eastern members conceded the timing equipment at Yas Marina was off when this was questioned. This leads to the logical follow up questions of how long has the timing equipment been off for? How many runs are suspect? How is a hot desert environment providing times so much quicker and faster than the rest of the world? BoostAddict contacted Yas Marina and the NHRA regarding this issue. Middle Eastern members state this was just a glitch and the circuit is NHRA accredited. That is not true. Yas Marina has not renewed its NHRA license since 2012. This is the response to BoostAddict's inquiry on the matter from Mark Hughes, the NHRA World Wide Consultant: This response means any run from 2013 on is suspect. We already have evidence the timing equipment is off and the only conclusion one can draw is that without an NHRA license, inspection, and accreditation the playing field is not level and that cheating has been going on. Frankly, it appears the cheating is rampant. As we do not know who cheated, when they cheated, etc., the only course of action is to invalidate all Yas Marina records from 2013 on from when they lost their NHRA license. Until this matter is resolved and Yas Marina again has an NHRA license and has been inspected this network will not recognize any runs or records from the drag strip as valid. When the database goes live on this network, all Yas Marina runs from 2013 on will receive an asterisk next to them indicating them as suspect and invalid. BoostAddict only received a response from the NHRA. Yas Marina has yet to comment on the matter despite being asked the same questions as the NHRA. However, if 'accidental miscalibration' is going on at a strip like Yas Marina with its reputation and resources and it failed to renew its NHRA license we wonder how many other suspect drag strips there are in the Middle East. It is stunning that the Yas Marina Circuit would not value its integrity and reputation higher than this. This issue now calls into question the validity of all Middle Eastern strips and times. It is unfortunate for honest enthusiasts who just want to enjoy their cars to be caught in the middle of this issue. It is simply a result of administrative failure and those who do not have the integrity to compete honestly on the 1/4 mile dragstrip with enthusiasts worldwide.

    Graph compares a Eurocharged Tuned C63 (6.2L M156) vs. the stock 2015 C63S. Almost a 100WTRQ gain from 50 - 100MPH. And this is stock.

    The BoostAddict Automotive Performance Network sees a lot of tuning from a variety of sources. Yes, some tuners are better than others. Yes, some tuners live primarily off their image and name, not their ability. Our goal is to inform the people of the choices they have and hopefully they spend their hard earned money wisely. The choices below BoostAddict believes are some of the industries most overrated tuners and that there are better options out there in the aftermarket especially for the money. That said, these 'tuners' somehow remain very popular (although a few eventually reached their inevitable demise). You may agree or disagree and that is the beauty of discussion and opinion. 10. Dinan This one hurts a bit to say as Dinan has done great things in the BMW world. However, this company has quickly gone in the BMW turbo era from one of the most sought after BMW tuners to the most overrated. BMW's have changed. Dinan has not been able to keep up with this change effectively. Just look at their 'Dinantronics' tune for the S55 turbo motor in the F80 M3 and F82 M4. Gains of 20 wheel horsepower for $2499. Are there better options out there? Yes. For less money? Yes. From multiple sources? Yes. That are not piggyback tuned? Yes. This piggyback point really highlights how Dinan has fallen behind. Piggyback tuning indeed dominates the BMW turbo market but Dinan is priced higher than basically every other tuning box option out there. Not to mention Dinan came off as hypocrites when they talked down on piggyback tuning only to do it themselves. The reasons given are nonsense as the actuality of why they went to piggyback tuning is they did not have access to the F-Series BMW ECU's to develop a proper flash tune. With the ECU's now cracked Dinan might as well take their box off the market. Too little and way too late. That might be why Dinan himself saw the writing on the wall and cashed out leaving his own company. 9. Gemballa What is Gemballa good for other than adding 'Lambo' doors to your 911? Not much. Well, they are good at living off the Gemballa name and providing overpriced body kits and wheels. The company originally was founded by Uwe Gemballa who was murdered in 2010 and this murder remains unsolved. Something bad went down in South Africa. The company went into a freefall after this and the rights to the name were purchased by those who wanted to continue to exploit the Gemballa name. Gemballa back in 2001 actually did some hardcore tuning and challenged for Nurburgring records with their cars. Since then they have become a status symbol for people with more money than brains. If you want a body kit and wheels, go ahead and check them out. If you want serious Porsche tuning go elsewhere. 8. Techart This is yet another German tuner offering more style than substance. Does Techart have some nice upgrades? Kind of, they offer overpriced bolt on packages consisting of exhaust systems and ECU tunes. The majority of the stuff they offer is said to come from various other German sources. Their primary source of revenue is bodykits and wheels. They offer suspension modules, exhaust tips, spoilers, things of that sort. Yes, these parts generally look good. If you consider serious tuning of Porsches body kits, lowering kits, and wheels, then Techart may just be for you. There is also the infamous story of how in 2007 Techart supposedly somehow ended up with some Porsche development motors for upcoming models that were stolen from a Porsche facility. Porsche brought a lawsuit against them and some people ended up in jail. How good does Techart look now? 7. ECU Tuning Group This is by far the least recognizable name on this list thus far and it should stay that way. This is the tuner that advertises by claiming to be the world's number 1 tuner. If you have to tell people you are number 1 you probably aren't number 1. This 'Group' has undergone several name changes. It originally was known as Singh Autosport and owned by a man named Jags Gill. Feel free to decide for yourself if this sounds like something the 'Number 1 ECU tuner' in the world would be up to: "A FedEx package passing through Memphis from England two years ago raised the curiosity of security agents who noticed the sender had spent more than $400 to ship stereo speakers he valued at $281. Now federal prosecutors in Memphis, suspecting a money-smuggling operation, have filed a forfeiture petition seeking to seize the $274,912 in dollars and British pounds they found hidden inside the two Sony speakers. The money and speakers sent from a "Mr. J. Gill" of Middlesex, England, was headed for Singh Autosport, a company in Fremont, Calif., that does not exist, according to state business records there. Also, although the contents were marked as "Sony accoustic speakers Ebay buyer," U.S. Immigration and Customs Enforcement agents and eBay investigators determined that no one had purchased the speakers through the online shopping Web site. A man identifying himself as "Jags Gill" began calling for the package, but could not provide serial numbers for the speakers. He later provided model numbers and dimensions for the speaker. Meanwhile, a month later in November 2006, authorities in Louisville, Ky., seized $231,891 in British pounds hidden in a table top at the UPS International Air Hub. The money was connected to a "Jaspal Gill" in London and is the object of a separate forfeiture action." Perhaps they mean number one in money laundering? Either way, there are better options out there than somebody that is just reselling tunes from European sources anyway. 6. Horsepower Freaks This one is technically dead. For those that know the story though this tuner went from being one of the biggest tuning names on the BMW forums to a story of a has-been that was completely mismanaged. At one point HPF dominated the BMW forum scene and was involved with BimmerBoost as far back as 2010. Having a giant like HPF on BimmerBoost elevated us and Chris Bergemann the owner always treated me personally with respect. HPF had all the E46 M3 horsepower records and was the king of the S54 platform. Then things quickly started to change. HPF started getting behind on paying its advertising tab to BimmerBoost and one would assume others. HPF still owes BimmerBoost $300 but it just goes to show you how bad things were if HPF could not pay that tiny tab. Chris Bergemann at HPF began to focus on young girls instead of building cars and running his business. He became about image and cheap promotion. There were reports of blown motors circulating as well as people leaving the company. There was a rumor of an employee stealing tons of money in parts and who knows what else. The company shut down with pretty much a whimper as Chris emptied out what he could from the HPF facility. He eventually sold the rights to the name to VividRacing who of course had no problem picking what they could off the bones. HPF is a tale of a spectacular failure and how forum image and fanboys can make you think you're a rockstar and the best in the business. Perception and reality are often very different things and that is true here. 5. RDSport / Racing Dynamics Back in the early BMW E46 days these guys had a following. That has since evaporated because they have done nothing of any merit. Their own website does not even feature the new BMW turbo 3-Series cars including the M3 and instead talks about yachting more than it does tuning. The company was founded in California by Federico Pavoncelli. Sometime in 2003 following a trademark issue Racing Dynamics became RDSport creating confusion as to what parts were the real deal and which parts were knock offs. The last thing they did of any merit was an S65 V8 stroker motor for the E92 M3 years ago but this gained little traction and RDsport was never able to tune it properly. BimmerBoost knows of an early RDSport stroker that received custom tuning and made substantially more power than on the default RDSport tune. Due to the owner being a complete asshat the tuner gave him back the stock RDSport tune and that owner does not even know this to this day. Regardless, RDSport's BMW tuning influence has evaporated and the company might as well not even exist. 4. Mansory This may be the ultimate example of style over substance. Mansory is all about the name and really not much else. How they manage to stay in business in frankly baffling. This network certainly can not explain it. Do they have nice body kits? Sure. For $38k+? Who is buying this stuff? Well, people in the Middle East mostly who think the Mansory name means something. It doesn't. The recipe is rather simple. Do some carbon fiber body kit, call it limited edition, and then get people to line up and pay for it. They claim to have high performance options for everything out there but you never see anything from them. For example, claims of 800+ horsepower twin turbo Huracans yet not a single dyno or 1/4 mile run is available. It is just one of those companies that will tell you they can twin turbocharge your Lamborghini and before you know it you're banging your head against the wall and wondering why you did not go to Underground Racing or Heffner for serious performance that actually exists. 3. Evosport Another tale of failure. This network has considerable experience with Evosport and was at one point threatened with legal action by them. Why? Because BenzBoost brought it to the attention of the Mercedes-AMG tuning world that Evosport was in debt and not delivering parts. As Evosport essentially started MBWorld this information was hidden from their user base with people being banned and posts on the topic were deleted. They could not do the same on BenzBoost. Evosport tried to solicit customers for money and BenzBoost happened to acquire proof. Suffice it to say there was no lawsuit and BenzBoost is still standing while Evosport has shut its doors. If a tuner starts asking you for more and more money and is not delivering, that is a red flag. Trying to punish websites for promoting awareness so nobody is taken advantage of is a pretty bad way to conduct business. That is why they are no longer in business. 2. ASR Engineering ASR Engineering is yet another tuner that doesn't deserve the free press it's getting here but people need to be aware of what they have done. The owner, Abid, may actually have no heart or soul. There are BimmerBoost members he still owes thousands of dollars to that he has failed to pay back for not delivering parts. That's known as stealing. We are just scratching the surface. ASR was allowed to take advantage of people on a certain BMW M5 board by the administrator (Gustav). Unlike that board, BimmerBoost threw ASR the hell out of here right away. So what happened? ASR would go on the mentioned M5 forum and claim big numbers by simply putting a nitrous kit on an E60 M5. The membership was blown away by this 'amazing' tuning for some reason. ASR then announced they wanted to build a twin turbo V10 and suddenly everyone started commenting on how awesome that would be and how ASR would dominate the BMW world with their M5's. Well, tuning a nitrous kit and a custom twin turbo S85 V10 are two very different things requiring two very different skill levels. You should not trust ASR to tune your radio let alone a car. Take a look at the state of one of the M5's sent in to ASR engineering was in when its owner finally was able to get it back. This happened to not one but two E60 M5's. Fortunately the owners could take the loss and move on but ASR and Abid did not even have the decency to put the cars back to stock. That is because many parts were missing (probably sold). Abid is trying once again to weasel his way into the BMW scene and find some people to take advantage of. Do not let him take advantage of you. 1. Hennessey Performance The tale of Hennessey's history is so long and such an epic clusterfuck that we do not know where to begin. It can only be said that Hennessey deserves his own article to detail just what a freaking mess he created and then tried to sweep up. If you want overpriced tuning and to satiate Hennessey's ego then maybe Hennessey is for you. Want a $300k Cadillac CTS-V with 1000 wheel horsepower? Despite the fact there are CTS-V's putting out more power for a fraction of this from other Domestic tuners building superior LSA's and LS9's? Want a stretched Lotus Elise with a turbo V8 for a million dollars? Call up Hennessey. We will delve into the history of selling parts off customer cars, lawsuits, and Hennessey threatening to fight people on forums (seriously) later this week.

    This is a pretty ugly beatdown but what it does is show just how fast the AMS Alpha 9 Porsche 997 Turbo package is in a street setting on pump gas. The video claims the Alpha 9 is running 600 horsepower with a custom Undercover Performance tune but considering AMS shows 800+ horsepower on 93 octane for the package there is some serious sandbagging going on here. The Stingray looks and performs as if it is stock. It ends up looking as if it is standing still. What we really learn here is that the Alpha 9 package on pump gas is tough to beat on the street. From a stoplight a rear wheel drive does not have much of a chance even if it has big power simply due to how effectively the 911 Turbo puts the power down. Ok, so it easily beats up on a Stingray and looks very fast. Now how about this car picks on somebody its own size? The AMS Alpha 9 Porsche 997.1 Turbo package starts at $19,995.95 and includes: TiAL Bolt on, Ball bearing turbochargers with advanced geometry billet aluminum compressor wheels Plex PBC Boost Controller COBB AccessPort W/Custom Tune 5.5” thick high flow intercoolers with smooth cast endtanks 4 ply reinforced silicone turbo discharge pipes Steel wire reinforced silicone turbo inlet pipes Cast Y pipe with smooth merge Carbon fiber upper intercooler ducts Line hardware and fittings Heavy Duty Injectors

    CAR decided to drag race the Audi RS7 and the BMW F13 M6. Now, the M6 is the lighter car. However, the advantage is in the RS7's court. It has an automatic transmission and all wheel drive so launching it as simple as putting your foot on the brake pedal, other foot on the gas, and then letting go of the brakes. Anyone can do it. The M6 takes a bit more skill and CAR does not seem to have it. Obviously a drag race is all about the launch. The torque these two twin turbo V8's put out is tremendous and the M6 will have traction issues. To get a good launch and actually make this a race the M6 needs drag rubber or at the very least the tire pressure lowered a bit and its tires warmed up to help. Obviously that is not always possible on the street and this result is what most people will see from a stoplight. The RS7 pulling away with no drama as the M6 fights for traction. Unfortunately, CAR provides no data on the trap speed or elapsed times for either car. Jump to to the 1:30 mark in the video to watch the obvious outcome.

    Evolve Automotive is about to officially launch their Stage I tune for the BMW S63TU V8 engine. We were sent a dynograph the other day which shows very large gains. Dyno gains are one thing and real world performance is another. Actual racing always beats dyno racing for displaying performance. So here is the Evolve Stage I tuned F10 M5 going up against some stiff competition. The first run is against a Ferrari 458 Speciale. The Speciale receives tweaks compared to the standard Italia including weight loss as well as more power. The engine gets a bump to 14.0:1 compression along with revised heads, tuning, and intakes. It results in 605 horsepower from the 9000 rpm 4.5 liter V8. Beating one in the manner the Evolve tuned F10 M5 does is incredible: This next race against the Audi R8 GT V10 Spyder is more difficult. Not because the R8 GT is more powerful as it isn't. It's heavier than the 458 Speciale due to its all wheel drive and has 560 horsepower sent through a single clutch sequential gearbox unlike the 458 dual clutch transmission. That said, thanks to the all wheel drive plus a fairly large jump (he starts rolling and gets on it early) the R8 gets a massive lead. To catch up and pass it takes a very powerful car. Catch up and pass is exactly what this Evolve tuned F10 M5 is able to do and it looks like a freight train going by. Jumping didn't spare the R8 the inevitable. Very nice runs here showing the Evolve S63TU tune performing well in the real world.

    This is the second round of the matchup between these two cars. You may remember yesterday the video posted shows the stock C63 AMG S beating up on this M3. The M3 has a JB4 S55 tune from BMS (Burger Tuning) but was run on Map 0 to try to get as close to a stock to stock comparison as possible. The F80 M3 in this video is running Map 2 and also has downpipes. Running an actual tune makes a huge difference as the M3 opens up a lead. The C63 AMG S starts to come on strong though. Oddly, it stops pulling and the M3 pulls ahead as if the C63 let off. One thing is certain here. If F80 M3 or F82 M4 owners want to play with a C63 AMG S on the highway they better be tuned with bolt ons. The C63 AMG S sure looks strong in stock form.

    3924 pounds is not what you call light. Especially for a C-Class. Mercedes missed their weight claims and targets big time here. They originally stated the new W205 C63 AMG would weigh 3615 pounds. Well, they missed that target by over 300 pounds. What happened? BenzBoost stated the given 3615 pound European curb weight for the W205 C63 was simply wishful thinking. Mercedes likely provided a figure without fluids and with different seats. In the USA the new C63 AMG comes in at 3856 pounds and the C63 AMG S comes in at 3924 pounds. BMW missed their weight target for the F80 and F82 M3/M4 but not to this degree. The C63 AMG is 300+ pounds heavier than its BMW rival. Maybe this heavy curb weight is why Mercedes-AMG tuned the M177 with more torque down low in the C63 AMG than the M178 in the AMG GT?

    I wrote this almost a year and a half ago on the other forum. Figured i'd dust it off and bring it to light. This is exactly why you do not want to inject meth in the CP on high HP cars. This is also the exact reason i went port injection a while back. If anyone knows how a OCC works by using velocity and change of direction will understand why CP injection is bad practice This is not my work besides N54 calculations at the end. Quote: you want to run the smallest possible without going over a certain air speed. 304 MPH or 0.4 mach is the point at which airflow meets increased resistance (drag) and flow losses are experienced. Depending on which turbo your running and what hp your looking for will determine piping size. to small is a restriction and to larger is laggy. generally for the average setup 2.25-2.5" is what works here is info i found on mach speeds of certain size piping relevant to cfm flow 2" piping 1.57 x 2 = 3.14 sq in 300 cfm = 156 mph = 0.20 mach 400 cfm = 208 mph = 0.27 mach 500 cfm = 261 mph = 0.34 mach 585 cfm max = 304 mph = 0.40 mach 2.25" piping 3.9740625 sq in = 1.98703125 x 2 300 cfm = 123 mph = 0.16 mach 400 cfm = 164 mph = 0.21 mach 500 cfm = 205 mph = 0.26 mach 600 cfm = 247 mph = 0.32 mach 700 cfm = 288 mph = 0.37 mach 740 cfm max = 304 mph = 0.40 mach 2.5" piping 4.90625 sq in = 2.453125 x 2 300 cfm = 100 mph = 0.13 mach 400 cfm = 133 mph = 0.17 mach 500 cfm = 166 mph = 0.21 mach 600 cfm = 200 mph = 0.26 mach 700 cfm = 233 mph = 0.30 mach 800 cfm = 266 mph = 0.34 mach 900 cfm = 300 mph = 0.39 mach 913 cfm max = 304 mph = 0.40 mach 2.75" piping 5.9365625 sq in = 2.96828125 x 2 300 cfm = 82 mph = 0.10 mach 400 cfm = 110 mph = 0.14 mach 500 cfm = 137 mph = 0.17 mach 600 cfm = 165 mph = 0.21 mach 700 cfm = 192 mph = 0.25 mach 800 cfm = 220 mph = 0.28 mach 900 cfm = 248 mph = 0.32 mach 1000 cfm = 275 mph = 0.36 mach 1100 cfm max = 303 mph = 0.40 mach 3.0" piping 7.065 sq in = 3.5325 x 2 300 cfm = 69 mph = 0.09 mach 400 cfm = 92 mph = 0.12 mach 500 cfm = 115 mph = 0.15 mach 600 cfm = 138 mph = 0.18 mach 700 cfm = 162 mph = 0.21 mach 800 cfm = 185 mph = 0.24 mach 900 cfm = 208 mph = 0.27 mach 1000 cfm = 231 mph = 0.30 mach 1100 cfm = 254 cfm = 0.33 mach 1200 cfm = 277 mph = 0.36 mach 1300 cfm max= 301 mph = 0.39 mach What you need to do is find you airflow rate based on : Basics you will use these numbers later on PRESSURE RATIO = (14.7 + your desired PSI) / 14.7 = PR convert CFM to LB per MIN = CFM x 0.070318 = LB/MIN (@ sea level and 112 degrees*) LITERS TO CUBIC INCHES DISPLACEMENT = # of L's x 61 CFM = Cubic Feet per Minute now using my car as an example: 3.0L (183. cid), 7300 Redline, desired boost is 25 PSI CALCULATING AIRFLOW RATE AT REDLINE and MAX PSI cid = Cubic Inches Disp. VE = Volumetric efficiency in percent .5 = (given) 4-stroke engine fills cylinder only on one-half the revolutions 1728 = converts cubic inches to cubic feet Airflow in CFM = (cid x rpm x .5 x VE%) / 1728 = CFM no boost CFM x PR = CFM under boost so for my N54: PR = (14.7 + 25 ) / 14.7 = 2.7 Airflow = (183 x 7300 x.5 x .85) / 1728 = 328.56 CFM (no boost) 328.56 x 2.7 = 887.12 CFM under 25 PSI A cubic feet of air (length+width+height) weighs different at diff. Altitudes and different temperatures. to simplify it well just assume we are at sea level and the air temp is 112 *. the conversion number is 0.070318. so for CFM TO LB/MIN = CFM x 0.070318 = LB/MIN 887.12 x 0.070318 = 62.38 LB/MIN (most speculate the precision 6466 is a 90lb turbo, this shows how much room is actually left in it. About 30% more left in its efficiency range) so here we have: BASIC ENGINE FLOW RATE = 328.56 CFM ENGINE FLOWRATE with 25 PSI = 887.12 CFM (62.38 LB/MIN) PRESSURE RATIO (PR) = 2.7 In conclusion you can see that a 2.5” duct is enough to support 913 CFM where as my car is pushing 887. I know its border line but here are some things to consider. Pros: 1. Drivability is more preferred 2. If I really wanted to squeeze the lemon I’m sure another .5PSI would overcome 3. The increased speed (about 50mph) has more of a “ram air” effect theoretically filling the cyl better. Cons: 1 meth distribution has less time . (direct port would probably be more preferred)

    The next gen battle between these popular M and AMG vehicles will soon be in full swing. Now we know the S55 engine in the BMW M3/M4 is underrated despite its claimed output of 425 horsepower. Thanks to Eurocharged Dynojet baseline testing of the new W205 C63 AMG S we know that car is also underrated despite its claimed 503 horse output. Eurocharged was kind enough to do a comparison between the two on their Dynojet dyno for us. You will notice the readout is not RPM but time and the reason for this is explained by Jerry@Eurocharged: "I did it in time view so you can see how long each car takes to accelerate under load. Ironically, both cars accelerate to redline in 13 seconds under load. Blue is C63S Red is M3 Both are my cars and 100% stock." The C63 AMG S obviously makes more power and torque. Considering its bigger 4.0 liter V8, this is no surprise. Its 467 wheel horsepower and 489 lb-ft of torque at the wheels comfortably exceed the M3 S55's ~425 wheel horsepower and ~430 lb-ft of torque at the wheels. This particular graph shows a bit of a spike in the M3's torque as the turbo comes on showing a value above 450 but this seems to be an anomaly from the norm. The reason the peak values are not listed on the graph is due to an accidental shift at redline while on the dyno causing a spike for the M3. Whoops, these things happen and so the comparison is not perfect. Considering how hard graphs like this are to come by we appreciate the effort from Eurocharged. What we can clearly see is the that C63 M177 has a big torque advantage namely down low. This is to be expected from the bigger V8. The BMW S55 motor has to rev more and has more lag. Interestingly the horsepower difference between the two toward redline is negligible. The M177 hits its power peak before the S55. The S55 uses its revs to keep power fairly level as its torque curve also drops toward redline. It is not a classic naturally aspirated M motor curve or a high rpm engine by any means but BMW still has to use revs to mitigate displacement differences to a degree. AMG also is tuning the M177 for more torque down low than the M178 in the AMG GT S which is tuned for more top end punch. The next overlay we will bring you is tuned versus tuned.

    These are two naturally aspirated Italian heavyweights slugging it out on the highway. A boosted German luxury sedan spoils the fun however. This video goes to show that the Huracan and 599 are very fast but in the boosted era all it takes is a tune on something like a CLS63 AMG equipped with the AMG M157 5.5 liter V8 to upset the exotics. The action obviously focuses on the Huracan and 599 predominantly and the CLS63 AMG only gets a cameo appearance at the end of the video. Regardless, the Huracan has a 5.2 liter naturally aspirated and direct injected V10 engine with 602 horsepower and 412 lb-ft of torque sent to all four wheels through a dual clutch transmission. The 599 has a naturally aspirated 6.0 liter V12 based on the unit in the Ferrari Enzo with an output of 612 horsepower and 448 lb-ft of torque. Unlike the Huracan power goes to the rear wheels. It does not have a dual clutch transmission but instead a sequential 'F1' manual gearbox. The 599 also carries an extra ~450 pounds. On paper this should be a good race and in practice it is with the Huracan having a slight edge. It is able to maintain the lead it opens up in the lower gears although the 599 appears to inch back in the higher gears. They both get smoked by a tuned M157 though. It sure is tough to beat the modern boosted German V8's once they get a tune.

    These German vehicles may both have dual clutch transmission and twin turbo powerplants but their execution is quite different. The Porsche 911 Turbo is well known with its all wheel drive and twin turbo direct injected rear engine 3.8 liter flat-6 putting out 520 horsepower for $149,520. The AMG GT S in comparison is a value at $129,900. It does have less horsepower at 510 and slightly less torque from its larger M178 4.0 liter V8 at 479 lb-ft compared to the 911 Turbo 487 lb-ft. Keep in mind though these figures are sent to the rear wheels in the GT and not all four as well as the fact the AMG GT has a front engine layout. The only way to truly know which one is making more power and torque is to get them both on the same dyno at the same time. The paper figures don't mean much these days with automakers sandbagging. Mercedes positions the AMG GT S against the 911 Carrera S anyway based on its price. Keep in mind there is a standard AMG GT coming as well that will be cheaper to combat the Carrera. That means Mercedes is offering close to 911 Turbo performance for close to Carrera S and Carrera pricing. When AMG rolls out their Black Series version of the car then they will truly take the fight to the Turbo and Turbo S. The fact the AMG GT is a complete mismatch to the Carrera and Carrera S and is being matched up to the 911 Turbo speaks volumes. Is it time for people to recognize that the 911 range is overpriced for what it is? EVO takes both cars on the track for a laptime comparison. The 911 Turbo laps quicker but this seems to be predominantly due to all wheel drive traction helping the 911 Turbo put its power down earlier on a tight course. The Mercedes is said to offer greater steering response and chassis dynamics but once again this is not the AMG GT model designed to topple the Turbo. It's designed to topple the Carrera S which it easily does. The 911 Turbo laps the circuit in 1:15.2 which is 1.8 seconds quicker than the AMG GT and this is a lifetime on a short and tight roadcourse. If you expect the AMG GT S to beat the 911 Turbo for less money with less power and torque you are asking too much.
