    There is something to be said for the M157's 5.5 liters of displacement. While the motor will be phased out over the next few years for the smaller 4.0 liter M177/M178 V8 the large M157 V8 still has the task of moving some of the heavier Mercedes-AMG vehicles in the lineup and the torque certainly helps in that respect. It definitely has a whole lot of torque down low. The baseline figure is 536 lb-ft at the wheels. Tuned? 725 lb-ft at the wheels for a gain of 189 lb-ft at the wheels. Huge but expected out of tuned M157's. What is odd is the baseline horsepower curve. The 421 peak horsepower figure is about 100 wheel horsepower off of what the car should be at based on previous M157 results. It's very low while the torque peak is about what it should be. Maybe AMG's software dials power back on the dyno (AMG has previously had dyno mode issues) or maybe there was some other issue. Regardless, the tuned numbers are right where the should be and very strong for a tune only car. 624 wheel horsepower and and 725 lb-ft of wheel torque will make for quite the ride.

    BimmerBoost member @sA x sKy is going for 1000+ horsepower in his BMW F82 M4. He was going to go another route but decided to have TPG Tuning build the motor and do the cylinder head work. The flow results are very similar to TPG Tuning's earlier flowbench data. It's important to note it is not the exact same data but similar data as it should be similar with the same S55 cylinder head. They did not just plug in the previous numbers so they have successfully ported multiple S55 heads which instills confidence and they even improved on the intake side: Very nice results over stock. TPG Tuning also built the bottom end with upgraded forged pieces and shipped it to @sA x sKy after they were done in just three weeks. A built S55 in just three weeks? I know a tuner or two who could learn something from this type of work, quick shipping, and excellent packaging. It is going to be fun to see where this ends up once it is done but it is progressing nicely:

    Do thieves need your BMW keys to steal your ride? Nope, as this video of an F10 520i being stolen in Dublin, Ireland attests to. It is surprising just how easy it is. The thieves break the window, open the doors, and use some sort of transmitter to start the car with the keyless feature. It seems convenience options like keyless go just make it easier for thieves to find another way gain access to the car. The car can be replaced of course and no doubt it is insured but it just goes to show how an alarm does not do much of anything against experienced thieves. Source

    Well, we asked where TTE 4.0 TFSI V8 turbocharger upgrade results are and here is an answer. An APR tuned RS7 running the TTE900 turbo upgrade managed to set a new quickest and fastest RS7 and overall 4.0 TFSI V8 platform 1/4 mile time with a 10.34 @ 135.56 pass. Certainly impressive but this is only a 2-3 miles per hour ahead of RS7 owners have been able to do on the stock turbochargers. AudiBoost member @kouzman managed to go 10.558 @ 132.56 on the stock turbochargers. Another RS7 improved on this time with a 10.388 @ 133.54. The turbo upgrade should provide much more than a couple miles per hour which tells us there is still tuning to be done but also that the conditions were not the most favorable. Density altitude was over 3000 feet which is very poor for record setting times yet records were set nevertheless. The car has some weight saving measures with Technocraft carbon seats and a lightweight battery. That is good for roughly 150-200 pounds off the stock car. It's good to see some results from the TTE turbo upgrade though and it seems APR will be incorporating these turbos into a Stage 2.5 package for the RS7. We want to see dynographs but claims are 765AWHP and 775AWTQ on race gas with 680AWHP / 725AWTQ on pump gas. How much further can they take it? In negative density altitude a 9 second pass is within reason.

    You think life is easy with a Ferrari? How about with multiple Ferraris? Well, think again. Imagine having a 458 Italia, an F12, and a LaFerrari. That sounds like a pretty sweet garage on paper but what happens when it comes time to grab the key to the Ferrari you want to drive? Yep, what do you do then? Use a Sharpie. Yes, a Sharpie pen in the answer to labeling your Ferrari keys. It's this kind of innovative thinking that no doubt produces the resources necessary to buy the cars.

    The S55 platform in the BMW F80 M3 and F82 M4 officially has a new quickest and fastest record holder. Maximum PSI took their DCT F80 M3 to the strip that features the Pure Turbos upgrade for the S55 3.0 liter inline-6 turbochargers and raised he bar. The previous 10.347 @ 133.82 pass was surpassed with a 10.316 @ 137.22. That means the quickest and fastest records for the S55 platform belong to this F80 M3 as it tops the record holding 135.5 pass. This elapsed time and trap speed come on a worse 60 foot at 1.743. What that means is if they get consistent 1.6X's out of the car (maybe 1.5's with some tweaks) the F80 M3 and F82 M4 platforms are on the doorstep of breaking into the 9's. Mods are the same as before until @Pure Turbos tells us otherwise: Pure Turbos Dodson clutches/baskets Flash/jb4/port injection Straight ms109 fuel Maximum PSI intakes, downpipes, charge pipes, 3.5"exhaust Evolution of Speed prototype intake manifold and intercooler Stock axles Exciting times in the S55 world.

    PorscheBoost member @918 spyder is not satisfied with his 991 Turbo which is the fastest 991 generation 911 Turbo in the United States. He previously ran a 9.71 @ 143 on a 150 shot and the stock turbochargers. Without the juice, the car managed 10.1 @ 137.02 miles per hour. So where does @918 spyder go from here? Well, here is what he has in mind: 1. Exhaust from By Design/Kline Inconel with titanium hardware 2. Custom headers by BBI 3. Special turbo's from By Design/BBI/Tial (non VTG) 4. Some suspension tweaks 5. Cobb Custom tune and Dyno by Robtuned 6. 200 shot nitrous by Vengeance Basically, bigger turbochargers from By Design and Tial without the VTG (Variable Turbine Geometry) element of the factory turbochargers. Turbo response will be sacrificed for much more power. BBi will provide custom headers and the exhaust as mentioned will be from By Design. Vengeance Racing will again provide their expertise with the nitrous which will be upped to a 200 shot. RobTuned will again provide the tuning through a Cobb Accessport to make the hardware all work as it should. The result should be impressive but we wonder how the PDK will cope with the extra torque from the turbo upgrade let alone when combined with a 200 shot of nitrous. How the fuel system will be upgraded to provide for the extra power is another question mark. Hopefully this all comes together as planned as if it does improving on the 9.7 @ 143 will not be much of a problem.

    TTE (The Turbo Engineers Germany) offered a turbo upgrade for the Audi 4.0 TFSI V8 over a year ago. The question is, why are more people not running the TTE900 4.0 TFSI V8 turbocharger upgrade? Tuning is one factor and perhaps not grenading the transmission is another. Fuel is always a concern with upgraded direct injection motor as well. The high res picture shows just how much goes into the upgrade and it's a beautiful overview of what they do for the 4.0 TFSI V8. Hopefully we see some results with this turbo upgrade soon.

    The 991.2 facelift brings with it minor styling changes. The average person likely would not be able to tell the the difference between the 991.2 and 991 GT3 models. What is important to focus on rather than the cosmetics are the mechanical changes. The major change expected is the addition of a manual transmission option for the GT3. This means buyers will not have to opt for the expensive and exclusive 911 R in order to get the high revving naturally aspirated flat-6 engine paired to a manual. Porsche will likely offer a slight power bump as they always do but the 3.8 and 4.0 liter engines are expected to carry over with some minor tweaks to the 991.2 GT3 and GT3 RS models. There is a rumor we might see a 4.2 liter GT3 RS. We will know more as the vehicle gets closer to its release date.

    The Brits at Autocar did a drag race between three very desireable and high performance cars. Of course, as it is Autocar they do not provide any meaningful drag race data but I suppose we should all just be grateful they did not do this drag race in the rain on a damp track like they normally do. The cars are very different from each other. The 458 Speciale has one of the best naturally aspirated V8's ever made. It is naturally aspirated though which means it is more difficult to squeeze power out of it than its boosted competition and also that it has less torque. Even without turbos it is an incredibly powerful motor (with 14.0:1 compression!): The Ferrari and the McLaren 650S do share similarities as both are rear wheel drive with dual clutch transmissions and mid-engine layouts. The McLaren has more power and torque than the Ferrari however. Despite Ferrari's claims the 650S is actually the lighter car by roughly 150 pounds depending on options. The Nissan GTR less power than either of the mid-engine exotics but it has more torque than the Ferrari thanks to its boosted V6 and it benefits from all wheel drive. This all wheel drive is what gets it the victory in the first run. They race twice and on the second race the McLaren takes the victory with a better launch plus the driver does not hit the limiter on the second try. It is not surprising the McLaren is the quickest and fastest of the trio. Especially considering the 650S has no trouble with the newer and faster turbocharged Ferrari 488GTB. It would be nice to have real data from all three cars but again as this is Autocar's video we should be happy with what we get.

    Great looking images here of a blue Lamborghini Huracan LP610-4 Spyder wearing bronze Loma wheels. Blue on bronze actually contrasts very well. The Loma MB1-S rims are 20 x 9 inches up front and 21 x 12 inches in back for a very wide contact patch. Loma rims are also TUV certified which is important for European buyers as well as those who want a guarantee of wheel quality and safety. Beautiful.

    The problem with dyno is that the 2 whell pair on the dyno have to be connected. That gives the best result.

    Yes just under 5000 rpm, thats low rpm for max hp, so if you go from 2-3 gear the rpm goes from 6400 to 5000 and then you get less hp up to 6400 rpm. Agree there is lot of hp. It is a normal problem with the M157 and max hp in around 4900 rpm, the best would be around 5500-5700 rpm.

    I'm not really sure what you're saying. Looking at past tuned M157 dynos it looks like the horsepower peak comes around 5000 rpm.
