    While in Mexico got a great opportunity to get some runs in with a 2015 Hellcat Charger bones stock with drag radials. Every one was really laid back and cool great looking and sounding car and for a stock vehicle impressive as well. We did multiple runs and all were roll on at about 50-140 and at 140 were around 4-6 cars. May need to find a way to hook through 3rd gear haha but the tires are new so i'm going to blow these off before changing out.

    Here is something to break up the typical posts regarding parts, horsepower, tuning, turbos, and performance upgrades that dominate the front page. Yes, we focus on fast cars but who can forget the kids that try to make their cars look or sound fast rather than actually be fast. They are known as ricers and we tend to make fun of them. You've seen them with the neon lights and loud mufflers that set off car alarms. This certainly fits the profile. Plus it's hilarious.

    It's here! Weistec has been hard at work on their AMG GT S product offering. You may remember that they did their baseline testing last month on the drag strip with the stock car and since then have worked their magic on the M178 4.0 liter twin turbocharged AMG V8. The initial product offering consists of an ECU tune and exhaust upgrades including a mid-pipe and downpipes. Let's take a look at the M178 ECU tune first. The Weistec AMG GT S baseline is on a completely stock car with 91 octane pump fuel. The dyno type is a Dynojet. The stock numbers are very strong at 480 wheel horsepower and 454 lb-ft of torque at the wheels. After the ECU tune only, peak horsepower goes up to 535 at the wheels. The torque number is the real eye opener as the peak torque figure rises to 580 with a major increase down low. The tune provides an additional 126 lb-ft at the wheels on 91 pump. That is massive. The tune only results are certainly impressive. Now let's look at the Weistec mid-pipe and downpipes. The difference between the factory downpipe design and the Weistec design is night and day. Obviously the factory units have integrated catalytic converters and Weistec eliminates this restriction. Their design is simply much less restrictive. The mid-pipe is part of the downpipe package and it bolts right up without any mounting issues. This photo gives a good idea of the fitment: Here are the key features: 100% mandrel bent and TIG welded Constructed of low carbon 304 Stainless Steel Bolt-on installation Improved exhaust note Improved exhaust flow Increased HP and Torque, especially when coupled with our M178 ECU Upgrade Now it is when these exhaust upgrades are combined with the ECU tune that we see the full potential of this M178 motor. Look at this graph: 551 horsepower at the wheels but the torque figure is over 600 lb-ft. To be exact, 620 lb-ft at the wheels on 91 octane pump gas. An additional 176 lb-ft of torque at the wheels at 3500 rpm is almost silly. The difference in area under the curve is astounding. The gains of course level off toward redline but this is not a motor that needs revs to make power. A boat load of torque is available down low. Weistec's ECU tune comes in at $2950.00: http://weistec.com/m178-ecu-upgrade.html The Downpipe and Mid-pipe upgrade is $4249.99: http://weistec.com/amg-gt-downpipe-and-midpipe-upgrade.html BenzBoost looks forward to seeing the result after tuning on the drag strip but the car is going to be well into the 10's. Frankly, with that much torque down low it is not out of line to state the vehicle is capable of mid to low 10's on pump gas with drag radials and just these bolt on modifications. Well done Weistec. Kind of makes you want an AMG GT, doesn't it? Additional pictures and a video below.

    Some very nice hardware going at it here. The video is from our friends DragTimes.info over in Russia who do some great events as well as presentation of the cars participating. This particular video features a tuned M6, a Ferrari F12, a tuned Audi S6, and a tuned BMW F82 M4. F12 vs. M6 The run is between the PP-Performance tuned M6 with a claimed 800 horsepower and a stock Ferrari F12 Berlinetta. The F12 gets off the line better but the M6 slowly closes the gap. We have a real drag race on this one as they are neck and neck with the M6 just managing to eek out the victory by the kilometer marker. The M6 has the faster 1/4 mile trap speed at 128.301 miles per hour to 125.915 and the faster kilometer trap speed at 166.559 to 162.917 miles per hour for the F12. Is the M6 reall at 800 horsepower though? It is performing like a bolt on car. But it is nice to see bolt ons on an M6 are enough to take an F12. S6 vs. M6 This same M6 next runs the tuned Audi S6 with an unnamed Stage 2 tune. On paper, this should be an easy win for the M6. The S6 gets a nice jump thanks to its all wheel drive but the M6 quickly passes and pulls. The BMW ends up getting the kilometer marker just over 2 seconds quicker which is a lifetime. The 1/4 mile trap speed of 128.891 for the M6 to the S6's 114.9 shows this is just a huge mismatch in power. M4 vs. M6 Big brother vs. little brother in this one. The M6 gets a much nicer launch and takes the lead right off the bat. The M6 is just stronger trapping 129.189 to the M4's 124.1 miles per hour in the 1/4 mile as well as its 167.683 in the kilometer to the M4's 160.233. The M4 puts up a respectable fight but the M6 is the fastest out of these four cars.

    I am about to take delivery of a C63 Blackseries as a daily driver and I was wondering what headers and exhaust system gives the most power and has the loudest sound? So far I am leaning towards iPE. My plans for the car are do all the naturally aspirated mods first and then go to the Weistec Stg 3. Please let me know what you guys think. Thanks

    I'm working on dynographs.com right now. I need a list of dyno machines. Here's what I have off the top of my head: Dynojet Mainline Dyno Dynamics Mustang Dynocom Dynapack Dynomite Maha Superflow What am I missing? Also, anyone have an interesting template idea for submitting dyno runs? Obviously you will pick your make, model, year, etc. Then dyno type, fuel, boost, mods, etc. What should I include?

    Mercedes changed their naming scheme around and what you see is essentially the new CL65 AMG. It is now called an S65 AMG coupe and is based on the W222 S-Class architecture but its own designation is C217. With that out of the way let's take a look at the car. MotorTrend truly loves the interior and exterior. It is hard to disagree as the car is simply beautiful inside and out. The technology and design employed are spectacular. Is the car worth the $230k they ask for it? Well, BenzBoost does not think so. Why? Because the 65 AMG models tend to depreciate like rocks. Not to mention, look at the performance figures. 12.3 @ 116.8 in the 1/4 mile from a 621 horsepower and 738 lb-ft of torque twin turbo V12? The 2015 version of the CL65 does not improve at all (and actually regresses due to weighing so much more) from the original twin turbo W215 generation V12 CL65 AMG that launched way back in 2003. No big performance jump after over a decade? The twin turbo V12 itself has barely changed. The original M275 V12 unit was updated to the current M279 V12 and yes it makes a bit more power and torque now but it is also moving 4753 pounds. The new car is obviously better looking and offers more technology inside and out but the performance has not improved with the rest of it. It needs a diet, badly. The S65 AMG Coupe may be the most expensive of the S-Class Coupe model line but at $230k it makes little sense. The S63 AMG 4Matic is a much better buy at $160k and includes all wheel drive. Despite the all wheel drive it actually weighs less at 4679 pounds. Less depreciation, better traction, less weight, and better performance. If you absolutely have to have a twin turbo V12 S-Class coupe with rear wheel drive the S65 is obviously the only choice. The question is, why do you need it over an S63 that is just as fast, cheaper, and arguably more capable? Maybe you have money to burn but even so it just is not the logical choice for performance in the lineup. The best argument for it is the prestige of a V12 but considering that V12 is very long in the tooth only those who don't know any better will be impressed by it. MotorTrend says really you want the V12. MotorTrend is wrong (they also call it an M275 when it's an M279 making you wonder if they even bother to do any research). Really what you want the is the more advanced M157 5.5 liter twin turbo V8 with its direct injection, lighter weight, higher revs, all wheel drive, and higher modability. They don't get it.

    Some great runs here from three German performance cars. We have a BMW F82 M4, Audi RS7, and W204 generation Mercedes C63 AMG going at it. The cars are all tuned so these are not stock examples. The race is a standing kilometer in Russia and the road appears a bit damp. That is what makes the first race between the BMW F82 M4 and the Audi RS7 so interesting. The RS7 with its all wheel drive getting off the line with a better launch is no surprise. What is surprising is how the M4 runs it down. At the 1/4 mile mark the M4 has closed the gap running 11.882 @ 124.8 miles per hour. The RS7 manages the 1/4 mile mark in 12.095 @ 121.534. The RS7 trap speed is more indicative of a stock car than a tuned one. The elapsed time is also poor even for a stock RS7. What is interesting is that by the kilometer mark the RS7 has the higher trap speed but the BMW M4 manages the better elapsed time and wins the race. This is definitely a tough run to explain as a tuned RS7 should have won this one rather easily with the better launch. The second race features a W205 C63 AMG Black Series with a Weistec supercharger against the same F82 M4. We do not know exactly which stage Weistec package this C63 AMG Black Series is running. It's a great race between the two with the C63 ultimately edging out the M4 up top. The launch between the two is very similar and the 1/4 mile mark has the M4 running 11.840 to the C63's 11.900. The trap speed of the C63 AMG is higher at 127.418 miles per hour compared to 124.343 miles per hour for the F82 M4. This higher trap speed at the 1/4 indicates the C63 AMG is pulling harder and it indeed takes the victory at the kilometer mark with a 20.993 pass compared to 21.133 for the M4 as well as the higher trap speed. The M4's performance is impressive in the sense that all it needs is a tune to get close to a supercharged C63 and best an RS7.

    Well, that didn't take long. The AMG GT S is already in the 10's thanks to Renntech. This is an improvement on their previous 11.285 @ 127.74. Additionally, this run took place in Florida and during the summer the conditions are hot and humid making the 10 second run look that much better in context. BenzBoost e-mailed Renntech asking for the full timeslip so we could see the full breakdown of the run but for some reason Renntech has yet to respond. Additionally, the ADV.1 wheel company is taking a lot of credit for this as if they have something to do with it. Yes, the car was running ADV.1 wheels but those wheels are hardly a good performance choice. This car would be much quicker on drag radials instead and smaller rims than the style over substance ADV's. It also looks to be lowered way too much for good weight transfer. We also are surprised Renntech is promoting ADV.1 considering Renntech's stellar reputation and ADV.1's less than stellar reputation. As we do not have the full slip we can not state what the density altitude was on the run or provide any other details at time time. We estimate the temperature was in the mid 80's with a density altitude of 1700+ feet. Congratulations to Renntech on being the first to break into the 10's with the AMG GT S! We expect on proper drag rubber and in cooler conditions for this car to go deeper into the 10's and much faster.

    Things are really heating up on the M177 and M178 twin turbo 4.0 liter V8 tuning front. You may remember that 'unofficially' it was leaked that Weistec was working on this turbo upgrade two months ago. We can now officially discuss it in further detail with additional information from Weistec themselves. Just earlier this month Weistec released their M178 ECU tune and and downpipes. Those modifications provide a boost of up to 551 wheel horsepower and 620 lb-ft of torque at the wheels on 91 octane pump fuel. BenzBoost at that time speculated what an impeller upgrade would take things to but Weistec is not just upgrading the impellers. They are providing a full turbo upgrade solution for the M177 in the W205 C63 AMG and S as well as the AMG GT and S M178. Yes, this is huge. Weistec is developing their own stainless steel turbo manifolds. The inlets and outlets are larger than the factory design for superior flow. The Weistec design is a cast manifold which they state is better at retaining heat and spooling the turbo. The turbos themselves are a V-Band design. This is important with the top mount and compact layout of the M177 and M178. Speaking as someone who has seen the M178 and the factory turbos in person, space is at a premium. This is early in the process but enjoy the computer designed engineering photos. With the stock turbos being good for over 600 lb-ft of torque at the wheels on 91 octane pump fuel just imagine what these turbos will be capable of. It's safe to say driveline upgrades will be necessary to really push the envelope with these turbos.

    Very impressive performance here from a supercharged C63 AMG that is just a hair away from breaking into the 9's. This W204 Mercedes C63 AMG features the Weistec Engineering Stage III supercharger package which utilizes a 3.0 liter twin screw blower. This is not a stock internal M156 V8 but a Weistec built example with their forged pistons and rods. This allows the motor to of course safely and reliably handle higher boost from the supercharger. The transmission also features Weistec engineering upgrades in order to handle the increased torque and aggressive drag strip launches. The 60 foot time is a very impressive 1.482 so the car is hooking well off the line. Racing Parts Solutions who ran the car on the Puerto Rican strip says the transmission is having some issues though. Once those are ironed out, this looks to be a 9 second car. Very impressive numbers from a 4000 pound AMG sedan. Video: https://www.facebook.com/grsmotorsport/videos/851463154908285/

    Last night I had the opportunity to run a stock M5. I think these dyno around 530whp. My car is sitting @446whp/471wtq but this was before the new BMS BEF with knock table changes which really helped performance. 2010 E90 AT 335i: stock turbo's, FBO, JB4 map 3 75add, MHD BMS E85 flash, E50 + 100% Meth F10 M5 DCT : stock Our last run I think he was becoming heat soaked and my car was pulling stronger (Meth has its advantages ) We plan to run again once I get stage 2 turbo's and he puts back on his JB4 and DP's. http://youtu.be/CMWtofIbIbs

    So it has been related to me by a few people and I've also read about all the problems getting the other chamber to seal. So I'm looking at a way to do this. Short of running a PLC I don't see a way to simplify the control I need with out running two port actuators. So my current idea is two run two small air springs connected back to back. Does anyone know how much force is generated by a standard waste gate at say 30-40psi?. Looking at specing out some Firestone Airstroke actuators and need data to size them. Here is the current one I'm looking at but not sure it will ave enough force. http://www.applied.com/apps/commerce/catalog/catalog.do?e=21&s=5751181 100's of sizes you can look through data sheets here http://firestoneip.com/search-product-resources/t/product-and-application?app=Manufacturing+%26+Industrial&resgrp

    This is a rumor but it is based on what is supposedly a leaked brochure. The brochure for the 2016 A45 AMG below features print far too small for us to read so that is why we are treating this as a rumor for now. It definitely makes sense though based on AMG offering standard and S models throughout the range. The W205 Mercedes-AMG C63 has a an S variant as does the E63. The 45 AMG models seem poised to join them. If they do, the standard 45 AMG cars will get an output boost to 376 horsepower with the S version offering 395 horsepower. AMG previously commented that they would not boost the output of the motor due to it not being fair to initial buyers. That comment was in response to Volkswagen talking about taking the production four-cylinder power title fromm AMG. Volkswagen's talk has amounted to nothing more than talk up to this point for years now although a 400 to 420 horsepower Golf is on the way so something will finally come of it. Mercedes-AMG appears to be ready to respond for 2016 with a stronger M133. Competition is a good thing, right?

    In this new era that puts a premium on efficiency and emissions (as well as parts sharing among motors) the major German brands have all gone to turbocharged and direct injected V8's for their sedans. In the past BMW had a high revving V10, Mercedes a supercharged V8, and Audi a twin turbo V10. Today we do not see vastly differing approaches. That is not to say the engines are all the same as they are not. There are significant design differences which we will explore in this article. They all are turbocharged however with direct fuel injection and all are V8 designs. Let's start by taking a look at the 4.4 liter BMW S63TU. The S63TU is based on the N63 4.4 liter V8 design. The 'S' designates a motor with engineering from the M division. The 'TU' designates a technical update. The N63TU received BMW's Valvetronic variable valve lift system as the did the S63TU which separates them from them from the standard N63 and S63 motors. In the case of the S63TU it also gets a compression bump to 10.0:1 and its peak boost pressure is stated by BMW to be 22 psi. BimmerBoost previously compared the N63 and S63 designs but will now be looking at the S63TU variant that sees duty in the F10 M5 and F13 M6. What is important to note in the S63 engine design is that it features a pulse tuned, cross engine exhaust manifold. This design of the manifold is illustrated well here: The color coded sections give an idea of how this works. The twin scroll turbochargers receive exhaust pulses from both banks, not just one. This is the main difference between the S63 architecture featuring twin scroll turbos and the N63 architecture using single scroll turbos. The S63 turbos are effectively receiving more exhaust pulses. This is part of the reason the S63TU makes more efficient use of its same 4.4 liter displacement and has greater output. This brings us to the Mercedes AMG M157. Out of the modern German twin turbo V8 motors AMG offers the largest displacement at 5.5 liters. This is great for low end torque and turbo spool. The AMG design is quite different from BMW. You will not find the trick exhaust manifolds with the turbos top mounted in the V or valley of the motor. The M157 uses a more traditional layout. It does not feature twin scroll turbos but does feature variable valve timing and direct fuel injection of course. Cooling is courtesy of water to air intercoolers. The M157 is more of a brute force approach. It's a big V8 with boost so of course it will make power. Speaking with certain tuners they believe the M156 and M159 were better motors than the M157. They had to rev high to make their power though and the M157 with its 6400 rpm redline does not courtesy of the turbo boost. Mercedes-AMG themselves has adopted a more advanced design for their new 4.0 liter twin turbo M177/M178 V8 with top mounted turbos located in the V of the motor. On the surface it is a very similar design to the Audi 4.0 TFSI V8 which we will now explore. The Audi V8 has the smallest displacement out of the bunch at 4.0 liters. Audi seems to know this and therefore built a very efficient design that responds very well to tuning. You will see that for yourself in the output comparison stock and tuned later on. It is as if Audi designed this motor to be tuned. The engine has top mounted turbos, twin scroll turbochargers, variable camshaft timing, and direct fuel injection of course. The twin scroll turbochargers are the main difference between the standard S6/S6 4.0 TFSI V8 with single scroll turbochargers and the RS6/RS7 design. The S6, S7, RS6, and RS7 all have the same 10.1:1 compression ratio. Audi explains the design choices as well as why they did not go the VTG (Variable Turbine Geometry) route well here: Despite the displacement disadvantage it really isn't giving much of anything up to the big boys offering 560 horsepower in the RS6/RS7 and 516 lb-ft of torque. This is less torque than the 590 lb-ft offered by the 2015 E63 AMG but actually more than the BMW F10 M5 500 lb-ft interestingly enough. At least on paper. AudiBoost will explore this motor in much further detail in a dedicated article later this week. Which brings us to the last motor fittingly as it feels a bit dated. The Porsche 4.8 turbo V8 is not a bad engine by any means. All it really happens to be though is a minor evolution of the original Cayenne Turbo 4.5 liter V8. Porsche gave it a bit more displacement and direct injection to update it since the V8's introduction in 2003. The Panamera Turbo and Turbo S may be the most expensive but when it comes to performance they lag behind the others. In straightline performance, specifically. Perhaps that is why it has a dry sump oiling system as it is not just a dragster. The Turbo S is rated at 570 horsepower and 553 lb-ft of torque for the $180k it costs but in practice it has less power and torque than any of these motors when wheel output is considered and namely when tuned. It does have an overboost feature which bumps torque to 590 lb-ft for short bursts which is something similar to a factory tune. As stated, it is not a bad motor but it just feels a bit dated. The Panamera has a playful chassis but it is a heavy car and even the mighty Turbo S can not keep up with the M5, RS7, or E63 AMG S. Here is a comparison chart to make it easy to identify the specifications of each motor: Engine: BMW S63TU AMG M157 Audi 4.0 TFSI Porsche 4.8 Displacement: 4395cc 5461cc 3993cc 4806cc Bore x Stroke: 89x88.3mm 98x90.5mm 84.5x89mm 96x83mm Horsepower: 560/575 577 560 520/570 Torque lb-ft: 500 590 516 516/553 Boost Pressure: 22 psi 14.5 psi 14.5 psi 12.3/13.5 psi Compression: 10.0:1 10.0:1 10.1:1 10.5:1 Redline/Fuel cut: 7100 6400/6600 6600 6500/6700 Valvetrain: DOHC 4V DOHC 4V DOHC 4V DOHC 4V Fuel Injection: Direct Direct Direct Direct With the factory specs out of the way we can now take a look at what these cars really put down to the wheels. These were all recorded on the Eurocharged all wheel drive Dynojet completely stock. Same fuel, same dyno. It does not get much more uniform than that: Now, the Mercedes fanboys are probably in an uproar right now due to this graph. Relax gentlemen, this is a E63 M157 dyno of a base care before the facelift and without the Performance Package option. The E63 AMG launched before the RS6/RS7 and the F10 M5 offering its M157 in a 518 horsepower state of tune. The following graph shows how things have evolved. The M5 is also a Competition Package car and not a standard M5. Turbo motors are allowing manufacturers to play with the output through software alone to top each other (and keep costs down). This is what an E63 AMG 4Matic looks like today: This is the E63 AMG S 4MAtic: That is quite the spread from the original pre-facelift and pre-4Matic all wheel drive E63 AMG S being sold today, eh? Mercedes now only sells the 4Matic E63 AMG S in the USA. The E63 has grown mostly through just software changes from the original 458 horsepower and 465 lb-ft of torque at the wheels to the 541 horsepower and 579 lb-ft of torque at the wheels you see now. Interesting how AMG responded, eh? BMW is also playing software games as here is a standard F10 M5: BMW with the Competition Package which gives the S63TU different engine tuning software increases output by 20 wheel horsepower and 28 lb-ft of torque at the wheels. Each manufacturer is very much aware of what the other is really putting out. This is a horsepower war yet they all are just trying to stay close to one another without taking things too far. They could each increase output further if needed and they each know it. Look at this aftermarket tune comparison courtesy of Eurocharged: They all end up surprisingly close to each other, don't they? The M5 has the least torque by a paltry ~30 lb-ft at the wheels compared to the others but clearly revs the highest so BMW can make up the displacement disadvantage that way through gearing. The RS7 is also making nice power up top though and interestingly despite being the smallest motor has the most torque tune only at 668 lb-ft. Do you think Audi did not know what they were doing? They gave the RS6/RS7 4.0 TFSI this kind of room for tune only gains so they would be right there with the E63 and M5 despite the heavy all wheel drive chassis and small 4.0 liter motor. This is all calculated. The M157 clearly revs the lowest out of the bunch but its displacement is helping it out with good torque down low. The Audi 4.0 TFSI V8 is still matching it yet revving out higher. It also offers more torque and power than the M5 S63TU up top until roughly 6900 rpm thanks to the increased rev limit from Eurocharged. The M5 revs a bit higher than this but it's torque and power are both lower than the 4.0 TFSI V8 before and after this rpm point. The motor that looks the most impressive is actually the smallest, go figure. You might notice the Panamera Turbo V8 is absent. It is difficult to get Dynojet graphs of the motor and we tried. The best we could do is this Mustang graph of a Panamera Turbo from Switzer before and after their turbo upgrade package: You will notice the Panamera Turbo is offering output closer to the pre-facelift E63 AMG than where the German performance sedans are now. Despite the crank horsepower and torque ratings AMG, M, and Audi are offering far stronger motors. It really takes a turbo upgrade for the Panamera Turbo to match the tuned examples from the others. There you have it. The twin turbo V8 era brings with it easy tunability and the manufacturers are all aware of this. They are positioning themselves to be close stock and tuned. If this network was to pick the most impressive motor though it would be the Audi 4.0 TFSI V8 followed by the BMW S63TU. The M157 is just taking more of a brute force than finesse approach and AMG themselves is changing the design now with the M177/M178 introduction. Porsche of course in this mid-size class is outgunned by all of them but this will change with the next generation Panamera. All turbocharged V8's, all direct injected, and all with basic similarities but different approaches. Is this era boring or exciting? You decide.

    What's up everyone? Not sure if this is the place to make a introduction, but I figured I would be hanging out the most in this section. Moderator, please move to different section if not. Here are some pics of my Ferrari 458 Italia and SLS Blackseries. I am getting a C63 Blackseries as a daily driver which should be here in a few weeks. I will be posting pics and videos of my build for anyone who is interested. -John
