    Hey everyone. A guy I know has a 2008 SL65 with speed driven intercoolers and a tune on it. I own a 2016 E63 S with awd and eurocharged's latest stage 3 tune. They tell me it makes 645 at the tire...... Idk if that's true or not but it has kicked the shit out of a lot of fast cars already. Last week I ran a 2010 C6 corvette with Cam, I take, exhaust, auto,3.45 gears Mickey Thompson ET streets that were aired down and a 100-150 shot of nitrous. From a dig, using race start I got him by 3-4 cars and then from a 30 mph roll I pulled him even more. How should I fare against this guys SL65?His car suffers really badly from heat soak.........

    Many readers are familiar with twin scroll turbocharger systems but it never hurts to in basic terms explain turbocharger technology which can seem like witchcraft to the casual car fans. In the most basic of terms, a twin scroll turbocharger is like having two turbos in one. How is that possible you say? Well, just think of your classic V6 or V8. There are two exhaust banks. Traditionally, an efficient turbocharger setup would mean two turbos hanging off the manifolds at the bottom of the car. Each is fed by that set of cylinder banks which it is connected to. It looks like this: Such a setup can make a ton of power, no doubt about it. A good twin set of modern single scroll turbochargers on a V8 or V6 can produce quadruple digit horsepower. However, look at all that piping. Look at the distance the exhaust gases have to travel. Can a single twin scroll turbo do the job of these twins more efficiently? Absolutely. Imagine if the exhaust gases traveled to the turbocharger right from the cylinder head. That poses a packaging problem but one that a twin scroll turbo helps alleviate. The new B9 Audi S4/S5 3.0 TFSI turbo motor is a great example of this: Audi placed a twin scroll turbo in the V at the top of the motor and with a very trick manifold feeds a single turbo with both banks of exhaust pulses. It is like having two in one yet also with the benefit of less piping, less travel distance, and quite simply greater efficiency. BMW started the trend with a pair of twin scroll turbochargers mounted in the valley of their S63 V8. It is the same principle except they are feeding two turbochargers with a cross engine manifold: BMW has two V8 twin turbo motors, the N63 and the S63, but the S63 outpaces the N63 considerably. Why? Because of the twin scroll cross manifold design. The N63 can essentially be turned into an S63 by changing the manifold and turbos and that is basically what an S63 is. Imagine turbochargers being fed by pulses from both banks instead of just one bank. That is exactly what a twin scroll setup does with the turbocharger taking in exhaust gases from both banks. This pays dividends in many areas. Spool is said to be increased which leads to low end torque gains as well as an improvement in throttle response. The turbos in theory will make more power through the rev range as they are continuously fed with exhaust pulses through the curve. One should also see a decrease in intake charge dilution during valve overlap along with lower exhaust gas temperatures. You also have reduced pumping losses and better fuel consumption. What are the disadvantages? There really aren't any other than more manufacturing and tuning complexity. In theory a good sized single twin scroll turbo will cost you less than a pair of high end traditional turbos. The main thing to get right is the firing order feeding the twin scroll turbo. For example a four-cylinder motor usually fires 1-3-4-2. You would want one exhaust passage to get gases from the number 1 and 4 cylinders and the other from the 3 and 2 cylinders. This may all sound too good to be true but the principle has been tested and a twin scroll setup is simply more efficient: More power through the curve? Yep: You also get the benefit of greater boost at lower engine speeds which is that low end torque and response benefit discussed earlier. You are going to see more and more twin scroll turbocharger applications in production cars. Expect variable geometry twin scroll turbochargers as well which means the turbocharger has vanes that can adjust. This way the turbocharger can adjust itself to maintain the speed of gas flow based on how much exhaust gas it is being fed. Turbo lag will never be eliminated but with twin scroll and variable vane turbo technology manufacturers are getting so close it may no longer matter. The modern turbo era is providing excellent response, efficiency, and power with fuel economy nobody would have thought possible not too long ago. Much respect to twin scroll technology!

    Nurburgring laptimes are basically a big dick measuring contest. That is fine of course as most things associated with automotive performance can be boiled down as such. The problem is everyone is not playing with the same sized ruler. What does this mean? Well, take Porsche's recent claim of a world record on the Nurburgring with the new Panamera Turbo. This tops the record set by the Alfa Romeo Giulia Quadrifoglio's 7:39 laptime. Alfa Romeo never proved they set a 7:39 time by providing a video as proof. Did they do it? Maybe, maybe not, but who knows at this point if it wasn't just a marketing ploy. The issue is Porsche did not provide a full laptime video now either. They simply wrote '7:38' and claimed a world record in their video and that is supposed to be good enough. It isn't good enough. The gold standard for proving a laptime is what Dodge did with the Viper ACR. They claimed thirteen track records and provided thirteen timed videos of the car lapping the tracks as proof. Lamborghini did a beautiful job showcasing their 6:59.72 Nurburgring lap from the Aventador Superveloce. A video of the whole run with timing included is exactly how to display the result. So why are we taking Alfa Romeo and Porsche's word for it? How do we even know if the cars are running factory tunes? Nissan started this whole mess when they would claim lap records with the R34 GT-R but everyone knew they were upping the boost. Part of the problem Nissan had was that old (and stupid) Japanese horsepower cap. Porsche accused Nissan of cheating with the GT-R on the Nurburgring back in 2008: Was Nissan using ringers? Nobody else was able to match Nissan's own GTR laptimes. Nissan provided videos as proof but the problem is a video doesn't tell us what software the car is running or what tires. Nissan's response to Porsche was to post a video of a 7:29 GTR lap and to tell Porsche they would offer Porsche test drivers training. They essentially mocked Porsche as beating them in their own backyard was unacceptable to the Germans. Complicating matters beyond manufacturers playing games with software, tires, or just making claims without proof is that the Nurburgring imposed a testing ban recently. Sections of the track were repaved, changed, and additional safety precautions were put in place. The Nurburgring tested on now is not the same Nurburgring and this is a large factor when even fast laps are over 7 minutes long. Minor changes will add up. Add into this that differing weather conditions will change laps considerably as will traffic on the track. BMW rented out the track specifically for their F82 M4 GTS test which of course gives them an advantage over times set with traffic to avoid. The result was a 7:28 time which tops the Porsche Carrera GT and Koenigsegg CCX. Does anyone really believe the M4 GTS laps a track quicker than those two lighter cars with mid-engine layouts that are far more aerodynamic and more powerful? Porsche and Alfa Romeo proved people will believe whatever they say. At least BMW posted a video of the M4 GTS making its run even though we do not know what software they used (and BMW does use special press software for marketing). Porsche just decided to put the Panamera Turbo ahead of the Alfa Romeo Giulia Quadrifoglio as Alfa Romeo never backed up their time with anything of substance and Porsche wanted big press for the new Panamera. You can not trust manufacturers to play this game honestly when the general public will not take any factors into account other than time X is less than time Y. If the Nurburgring is to be taken seriously as an automotive testing ground a standard must be created where production cars are brought in to set the records and more than one driver not on the manufacturer payroll get a crack at setting a time. Until then, you can not trust anyone because there is simply too much BS being thrown around. That is unfortunate for those competing honestly. Enough of the bullshit. If we are going to use the Nurburgring for comparisons then testing for timed and record laps must be standardized.

    While direct fuel injection brings with it certain upsides such as greater fuel economy and higher compression ratios on pump fuel there are downsides to the technology as well. One such downside is carbon buildup which you see on the intake valves. This is why walnut blasting to clear out carbon deposits is popular maintenance especially considering buildup can and will reduce engine output. Not to mention if it gets severe enough it will cause other problems. Newer motors are better about this (especially engines with dual injection systems where fuel sprayed on the backside of intake valves helps keep them clean) but anyone with a direct fuel injected motor would be wise to monitor their carbon buildup situation. You don't want that much gunk just sitting in your motor, do you? The photo is from carbon deposits removed from a VW TSI engine with 78k miles.

    Just in time for July 4th, right? If American automotive culture can be represented by any one thing it is definitely V8 horsepower. The Americans simply make the most. Disagree? Well, you can talk to Steve Morris Engines about some of their builds like this absolutely absurd twin turbo big block. Absurd in a good way of course with 4000 horsepower on race gas and how about 3000 on pump? That 3000 figure comes at only 20 psi by the way. Who knows what it really does cranked up. Here are the specs: Cast BRODIX 5" bore-space block with in-house custom machining Premium SME piston package for big boost Billet crankshaft and aluminum connecting rods Custom cam profile Jesel belt-drive and MOROSO dry-sump oiling system INNOVATORS WEST balancer with integrated crank trigger Cast BRODIX cylinder heads with SME port program and modifications JESEL custom shaft-mouted rocker system Custom billet valve covers Fabricated (optional billet) intake manifold Competition machining and assembly Yes, this is street legal and goes into a street legal car. You might balk at the $63,999 price but the horsepower per dollar is unbeatable if you consider that 2000+ horsepower Underground Racing builds are six figures and that they will only make half the power. This is street legal performance on a whole different level. The video below covers the details directly from Steve Morris. Well worth a watch for any enthusiast. 'Merica!

    If you are squeamish don't watch this. Many people write that before videos but this is a very disturbing video that captures someone in China using their car as a weapon. There are stories and rumors from China that killing an injured pedestrian is preferred than paying out a lifetime of restitution but this is on a whole different level. What takes place is the white car aims for two people next to a taxi. One gets in and the other gets run over by the taxi the white car hits. That right there should stop everything but it is just the beginning. Those in the taxi get out and the white vehicle backs up and begins another assault. The passenger from the taxi is run over. The car backs up and then runs over the other person who was under the taxi. Absolutely insane. This road rage continues as the white vehicle circles the injured as if it is stalking more prey. Another taxi comes into the picture and is rammed. The taxi driver gets out and attempts to get into the white car which backs away. Eventually the car just leaves the scene but this is shocking, disturbing, and just psychotic behavior that can not be explained.

    Potentially an interesting drag race here as it pits three very fast cars each representing their nation against each other but Autocar screws the whole thing up. The Nissan GTR and the Porsche 911 Turbo S are not all that different from each other. Both feature twin turbo six-cylinder powerplants, both have all wheel drive, and both have dual clutch transmissions. The GTR is heavier however with less torque on paper. No direct fuel injection for the VR38DETT motor and of course a front engine layout. It's also quite a bit cheaper than the Porsche. The best horsepower per dollar value of the trio is the Hellcat but you already knew that. Just as you likely knew it is the heaviest car of the trio. We're talking 400 kg more than the 911 Turbo S or in other words more than 800 pounds. As this is Autocar they have no clue how to launch the Hellcat. The car is still spinning its tires when they go green. Why? What's the point of the drag race if the Hellcat never even gets a chance to hook up? Of course they also provide no data because it's Autocar and we should all just be happy they aren't doing this in the rain while sipping tea. They try again and the Hellcat again does its stupid spin until the tires go green routine. At no point do they think of going from a roll because producing quality performance comparisons escapes the people at Autocar. Essentially we get a frustrating and pointless drag race video. Someone tell these idiots at Autocar THIS is how you drag race a Hellcat.

    Just ran across a reference to the MGTOW community and have yet to look into it, but it immediately hit home on the feelings of men playing by a stricter set of rules than women nowadays. Anyone part of this "movement" or just follow any forums related to it?

    Torgus started a thread For Sale: E92 Pre LCI headlights in Buy/Sell - Parts
    Located in MA Willing to ship at buyers expense. I only ship via my commercial UPS account fully insured. I also know how to correctly package things. I only accept Paypal unless you are local then cash. Left and Right Stock E92 Adaptive Pre LCI headlights. Fully loaded with bulbs, ballasts, etc. These retail for over 2k from BMW. Asking $800 + shipping. Firm. I'm installing new modded headlights on my car this weekend and will have pictures of the ones for sale once they are off. I'll get some while they are on the car as well. Ask anyone who knows me and they will tell you how I take care of the car inside, outside, and the mods I install(no knock offs or cheap Chinese shit). On long drives the car and headlights(expect for the turn signal) gets blue painter's tape to protect it's front on the way to shows. Here is a picture for now, don't mind the water droplets that dried on the lens: These are perfect if you want to mod your lights or need replacements. I also have a spare set of lenses which I will include at no cost. You can choose what set of lenses you want to use. Polish a set or what have you or just resell them. They are worth about $50 bucks each used. More pictures of the car and headlights here: http://www.e90post.com/forums/showthread.php?t=1264348

    Congratulations to Autowerks Automotive in Australia who showed it is indeed possible to run 9's on the stock M156 engine internals. We knew this would be coming as just earlier this year an Australian C63 with the Weistec Stage III setup ran 10.1 @ 139. The difference here is better conditions and custom tuning by Autowerks Automotive. Full specs: Weistec Stage 3 Built transmission 60mm pulley Race fuel ( 17 inch slicks Hoosier Skinny fronts Stock M156 internals 655 rear wheel horsepower Exhaust cut out's Weight reduction including removed back seats This is a P31 package car which means stronger engine internals borrowed from the SLS M159. Congratulations to all involved and on the quickest stock internal C63 in the world.

    Considering the absolutely atrocious Hellcat drag race video posted the other day it only seemed fair to post a video showing what a Hellcat can actually do when it puts the power down. One way to get the Hellcat to put the power down properly is to go from a roll. That is what they do in this video after their incessant babbling. Skip to the 4 minute mark for the action. They screw up the first run with the M4 getting a major jump. It doesn't matter though as the Hellcat reels it in and pulls past the M4 as if it is standing still. The second run has an even start and the M4 gets demolished. Ok, they state in the video the M4 gets its ass handed to it but what are they racing a stock M4 against a tuned Hellcat for anyway? We know the Hellcat is quicker and faster stock for stock and when tuned of course it has a huge power advantage. Beating up on a stock M4 is nothing to proud of especially when the race has to be tailored to the Hellcat. The main point here is Hellcats are stupid fast and they struggle with traction. If you want to show what they are capable of either run drag rubber on the track or go from a roll. Don't do what Autocar did.

    The other day BoostAddict posted an article regarding Weistec's legal action against Dime Research and Development or Dime Consulting. Clearly those involved with Dime realize the walls are closing in so what are they doing in the meantime while the courts play this out? BS'ing people on forums and trying to do as much damage to Weistec as possible. It's a very simple recipe and it happens more often than you think. Simply offer someone some parts for a discount or free in exchange for posting a thread including a positive review while bashing a competitor. It happens all the time. MHP was the best at this. The owner even asked me directly to create fake accounts for him on other forums so he could do this. When a ship is sinking which in this case it is a company it takes cash to stay afloat or keep the doors open. When HPF (Horsepower Freaks) was in a similar position the owner would go on the forums and post videos of how his shop was filled with cars hoping to instill confidence in potential customers. It's easy to see through the BS though if you have enough experience or have been on the forums long enough. In this instance, it was way too easy: This 'Guilty' fellow posts a graph claiming it is a C63 M177, bashes Weistec, and says how great his tune is. That tune curve looks pretty familiar though, doesn't it? Very similar but not the exact figures yet clearly an AMG GT M178 graph and not a C63 M177 graph. If it was the exact same graph as the graph Weistec advertises with that would be too obvious even to your typical forum moron. Maybe they took another run file or just changed a correction factor? If we had the actual bevvy of dyno run files from the Dynojet software testing we could prove this. Oh, it just so happens we do: That would be runfile 88 from Weistec's ECU tuning. Exact same baseline and the exact same after the tune numbers. Because it's the exact same files. This poor schmuck is either a Dime schill or he believes that is the runfile for his car. Either way the guys reading on forums just assume this is the truth and that they can get the same results as Weistec for less money. If the software is stolen and no development work took place, yep, it's possible to offer a lower price. For those who would like to verify for themselves, here are the Dynojet run files: RunFile_002_stock.drf RunFile_088_Testing.drf As stated, it's a simple recipe. Post a graph, have a few fake accounts chime in where the administration doesn't care because it's too big to care, and you get the desired result which is herding the sheep in the direction you want them to go. Now tell me, who would you trust? The company facing litigation from multiple parties with people involved accused of stealing millions and potentially funneling money overseas that advertises software they did not even develop or BenzBoost? Hmm: It seems not everyone is so easily swayed:
