Low 11's on street tires tune only is an incredible achievement and exactly what a Renntech tuned E63 was able to do recently. This is now the new tune only stock tire record and was done in Florida at Palm Beach International Raceway. This E63 is the same car that ran 12.0@116 stock. With just a tune it was able to gain 10 MPH and a full second in the 1/4 mile. Incredibly impressive and clearly a 10 second car on drag radials or even the stock tires in cooler weather. ...Published on 04-15-2012 08:42 PM
This is what we have been waiting to see, a victory for Mercedes and for Nico Rosberg to start living up to his potential. Congratulations to the Mercedes-Petronas Formula 1 team and to Nico Rosberg for a well deserved victory at the Chinese Grand Prix. An interesting tidbit of info is that the victory comes on Nico's 111th start which was 111 years after the first Formula 1 victory for Mercedes in 1901. Full race results and standings below. ...Published on 04-15-2012 08:32 PM
BMW got another podium in Long Beach, California finishing in 2nd and 11th. The M3 finishing in 11th was involved in an accident on the first lap which required lengthy repairs. The 11th place finish puts the second car out of the points so BMW is now tied for the overall manufacturer lead. Chevrolet took the victory and the C6 ZR1 race car had a strong showing with 1st and 4th place finishes. Corvette Racing appears to be the BMW's biggest challenge and rival in their quest for a third straight championship. ...Published on 04-12-2012 07:43 PM
The 997 Carrera GTS is no slouch. It essentially bridges the (narrow) gap between the Carrera S and the GT3. With the PDK transmisison, it is a very quick car with its 408 horsepower 3.8 liter flat-6. The 1M is the slower vehicle stock for stock but all of us on BimmerBoost know how the N54 twin turbo under the hood responds to modifications. Well, with just a tune this 1M is able to make fairly quick work of this stock GTS in a roll on race. We are not sure what tune the 1M is running but the result is impressive. ...Published on 04-12-2012 04:48 PM
Well, the reports were all correct and now we have the most powerful G-Class models ever offered. The G65 AMG packs a 612 horsepower and 738 pound-feet of torque M275 twin turbo V12 making for a monster of a G-Class. The G63 AMG gets the new twin turbo 5.5 liter M157 V8 with 544 horses. Both models also appear to be coming to the USA late this year which is great news although the price tag will no doubt be hefty. Still, we are glad Mercedes made these as they are absolutely absurd. ...Published on 04-12-2012 01:50 AM
The new BMW F30 328i continues to rack up wins in comparison tests. Just last month it beat German 4 cylinder sport sedan challengers and now Car and Driver added the Infiniti G25 and Volvo S60 to the mix. The Volvo is the most powerful and quickest car in the test by virtue of its turbo inline-6 with 300 horsepower seeming a bit out of place against the four cylinder competition (excluding the naturally aspirated V6 of the G25). The Volvo stacks up well pricing wise but clearly the motor is more akin to competing against the 335i and not the 328i. ...Published on 04-12-2012 12:24 AM
It looks like Audi will be announcing its acquisition of Ducati shortly. AMG was reported to be in the mix but either their interest was overblown or they never had any intention of purchasing Ducati. Regardless, Reuters reports the acquisition may be announced next week as inside sources have revealed that the deal was indeed completed. No information on the purchased price released yet. This means that now Audi will have motorcycle division to compete with BMW Motorrad heating up the competition considerably. ...Published on 04-11-2012 11:46 PM
Many of you have heard of the Nardo Ring which is basically just a big circle that cars do high speed testing on in Italy. The 7.8 mile long and 4 lane wide track can be seen from space. The banked oval allows high speed runs in excess of 200 miles per hour. Automakers have been renting the track from Protipo SpA (the previous owner) for years but now they will have to speak directly to Porsche to get time on the track. Full press release below. ...Published on 04-11-2012 04:31 AM
Political issues in Bahrain are putting a lot of pressure on Formula 1. Reports are that teams are hoping that after meetings in Shanghai the race in Bahrain will be cancelled. There have been protests in Bahrain against Formula 1 and at least one person has lost their life in these protests. We will know what happens after the race in Shanghai but for now Ecclestone is proceeding with the GP as if it is business as usual. We hope the event does not spark something far more serious (and dangerous). ...Published on 04-11-2012 01:30 AM
The all electric Audi R8 E-Tron is on the way but the drivetrain poses a problem in the sound department. The electric powertrain is simply too quiet and that poses a problem for pedestrians. So, Audi is having "sound engineers" compose engine sounds. Yes, they are composing gasoline engine sounds for the car. At least in the E-Tron R8 it is understandable due to being all electric so is better than what BMW did with the new M5. This synthetic engine sound trend is very disturbing however. ...Published on 04-10-2012 09:00 AM
Took a few hours today to do some N20 dyno testing and tuning. For those that have been living under a rock for the past few months the N20 is a 2.0L 4 cylinder turbo and motors replaces the N52 motor used in the 328i, among other cars. We only have around 200 miles on the car but so far first impressions are very positive. Compared to the previous 328i N52 motor the N20 is much more responsive and has excellent low end torque characteristics. In addition it has much more power to redline. It also delivers better fuel economy. In short, it really blows the N52 away in all categories. Below is an N52 vs. N20 dyno comparison. ...Published on 04-10-2012 08:00 AM
We figured a Cayenne GTS would come with the 958 generation. They did it with the previous generation and with the launch of a Panamera GTS it only seemed natural the Cayenne would get the same treatment. The leak comes courtesy of Porsche themselves through their customer magazine, Christophorus. The pictures here are screenshots from the downloadable version of the magazine although it seems they were put up hastily as the displacement listed on the specs of the V6 model put up next to the GTS to compare is listed incorrectly. As far as the specs of the GTS are concerned, expect it to mirror the Panamera GTS with the V8 receiving tweaks but it also appears to be getting a shorter final drive. More to come soon as it is officially unveiled. ...Published on 04-10-2012 06:54 AM
We have reached and passed our first major milestone, the 10,000 member mark. GermanBoost would like to thank all our vendors and users for their support in making this happen and making it happen so quickly as well. We have passed several forums on the way here and now have definitively established ourselves as a legitimate alternative to the corporate automotive forums. One that puts the German performance automobile enthusiast first. With a base of 10,000 members (and growing!) it is clear that we are not going anywhere anytime soon. ...Published on 04-10-2012 06:00 AM
Wesitec recently released their M157 tune and here we get to see it in some real world action. The CLS63 AMG straight up destroys the C63 AMG and this is not much of a race. The CLS just puts bus lengths on the C63 practically instantly. In the defense of the C63, the Powerchip tune is one of the weakest available for the M156 platform and rumors are that Powerchip is not even a functioning business any longer (more on this at another date). The Weistec tuned car is so strong though that it really would not matter what tune the C63 was running although it would have at least been a better fight with a different tuning option. ...Published on 04-10-2012 04:06 AM
Now, the NSX here clearly has a lot of power. It is a twin turbo car with a claimed 700 horsepower. The Porsche 997.2 Turbo S is bone stock. The NSX is clearly hard to launch as in the first race the car goes sideways with the driver almost losing it. In the second race the NSX driver appears asleep at the line with a very poor reaction time but his elapsed time just bests the 911 Turbo. The NSX is the faster car with a 181.2 MPH trap speed to the 177.8 of the 911 turbo. All the 911 Turbo needs is a tune to surpass the NSX though making the NSX barely edging a stock 997.2 Turbo S not all that impressive especially for the horsepower claimed. ...Published on 04-10-2012 01:34 AM
We are going to be seeing many more M156 versus M157 comparisons as more and more owners of both of these motors modify them. This is a great race but obviously the M159 (based on the M156) V8 in the SLS AMG is at a power disadvantage versus the factory twin turbo M157 motor. The SLS holds off the CLS 63 AMG early on thanks in part to its quick shifting transmission but eventually the power of the ecu tuned CLS 63 AMG shows up top and it walks away. The SLS only has a full Supersprint exhaust so it does quite well considering the horsepower and torque disparity. If the SLS had some boost as well, say from a Weistec supercharger, the result would likely be quite different and in the favor the SLS. ...Published on 04-09-2012 10:46 PM
GIAC has released their software for USA Audi TT-RS vehicles. Depending on the octane gains range from 30 horsepower at the wheels on 91 octane up to 69 horses at all four wheels on race gas. Maps suited to your octane are available and can be switched using a hand held flash loader. The vehicle shown in the dyno graph below is a 6 speed manual as all USA TT-RS' are. In addition to the horsepower gains throttle maps are changed, the low speed torque limiter is removed, and the speed limiter is removed. Stage II software from GIAC is coming up next. ...Published on 04-09-2012 09:41 PM
Introducing the Speedart SP91-R 425 package for the new Porsche 991. It includes wheels, an aero package, exhaust, and ECU tune. The aero package consists of a front spoiler, side skirts, rear wing, and diffuser. Performance upgrades include an exhaust and ECU tune. The tune boosts power for the 991 Carrera S by 25 horses hence the name of the package being 425. As usual, no dyno graph or performance numbers are provided to support the gains and this is why we do not like European tuners who live more off their name than the results of their tuning package. ...Published on 04-09-2012 09:29 PM
The X5M is very quick for an SUV namely when going from a stop. The 2011 Corvette Gran Sport with the LS3 6.2 liter V8 is hardly a slouch either and obviously much, much lighter. The all wheel drive and automatic make the X5M fairly nasty out of the hole and it is much easier to launch than this 6 speed vette. The race goes exactly as it should with the X5 getting the better 60 foot and establishing a lead out of the hole with a 1.78 60 foot compared to the 2.12 of the C6 and it manages to hold off the vette with a 12.3@111 versus a 12.7@112. With a better launch the C6 would take this race although it is close which certainly shows how impressive the X5M is. ...Published on 04-07-2012 04:10 AM
