    Hot on the heels of Weistec setting the quickest AMG GT S 1/4 mile pass record comes their Mercedes-AMG W205 C63 S 1/4 mile testing. Emphasis on the word hot as the weather was over 80 degrees. As these passes took place on the same strip on the same day as their AMG GT S record runs the density altitude was in the ~3000 feet of elevation range. Not exactly good conditions and California Dragway is not a quick strip to begin with. What we need to focus on here though is the before and after numbers. The baseline is stock on the factory rubber along with pump gas and the tuned runs include the Weistec M177 ECU flash tune and their air filters on the same rubber and same fuel. The baseline result is a 12.033 @ 115.60. This is a good example for those who need to understand the weather and location plays a huge part in 1/4 mile results. This is a realistic baseline result in California weather: So what difference does the Weistec ECU flash tune along with their air filters make on the M177 4.0 liter direct injected twin turbo V8? Just under five miles per hour of trap speed and just over half a second of elapsed time. A textbook example of how trap speed gains and elapsed time gains should correlate: There are a few important things to note here. First of all, the 60 foot improves on the same street tires. Why? Because the torque down low is increased with the tune meaning providing there is enough traction the car can get off the line quicker. Secondly, the tuned run takes place just 20 minutes after the baseline run. They quickly flashed the car and ran it again without giving it an extensive cool down or waiting for more favorable conditions such as for the sun to set. The tuned run was done at noon. This is about as real world as you are going to get seeing the before and after impact of a flash tune on the M177 platform. As stated regarding the AMG GT S results more favorable conditions will produce more favorable numbers. Expect to see 10 second bolt on tuned W205 C63's fairly soon.

    It is nice to get a variety of graphs from different dynamometers on the M177/M178 engine platforms. World Motorsports has a Mustang dyno and they posted their ECU tune only AMG GT S results. Look at that huge bump in torque as early as 2800 rpm! Unfortunately they did not include peak figures on the dyno but it is relatively easy to see that peak torque rises by just over 100 lb-ft at the wheels. There is also a lot more area under the curve. Peak horsepower goes up roughly 60 lb-ft of torque at the wheels. We would like to know the fueling and boost details. Also, is this World Motorsports tune or someone else's tune? In the past Weistec has done tuning for World Motorsports which tells us they source their tunes from someone else. Speaking of which, Weistec's M178 tune shows a similar curve. As their graph is from a Dynojet the horsepower and torque gains are larger due to the different type of dyno. On the same dyno this may be close to a wash. Keep in mind the Dynojet baseline is 480 wheel horsepower and the Mustang baseline for the M178 is just over 400 wheel horsepower. Just goes to show how much the numbers can change based on the machine measuring them.

    Try it on another internet source to confirm. Like your cell phone. If it loads fine there you know it's on your end.

    Chrome for both. I'm thinking issue must be on my end. Forum is never that fast takes a few seconds to load banners and I end up clicking on the wrong thing as everything moves after they load.

    Trying to get a truly independent P1, LaFerrari, and 918 Spyder track test has been basically impossible. Ferrari forces everyone to test the LaFerrari on their home turf on their terms. They also refuse to allow the LaFerrari to attend comparisons against the other two cars in which they do not control the conditions. Does Ferrari sound like a bunch of babies? Good, because that is exactly what they are. Enough about Ferrari's insecurity. Let's focus on this independent test with British Touring Car hotshoe Mat Jackson behind the wheel of these supercars at Silverstone. What was the result? 1. McLaren P1: 58.24 2. Porsche 918 Spyder: 58.47 3. Ferrari LaFerrari: 58.58 Well, those numbers might cause a few heart attacks over at the Ferrari headquarters. To be noted, the cars are all close and they did do several laps to get the best time possible. Also to be noted, the McLaren P1 ran first when the track was the most damp. Now, a British supercar wins on a British track in the hands of a British driver? Is there some bias? Well, if so, they mitigated it by having the P1 on the track when the conditions least favored it. The way they applaud the P1 though reinforces how strongly pro-McLaren this crowd is. They will go to the Santa Pod drag strip next but we would also like to see more road course testing on another track. The P1 takes the win at Silverstone and the LaFerrari brings up the rear.
