Wish AudiBoost could say this this is a good race but the Camaro ZL1 simply gets demolished. The Camaro is no slouch with a supercharged 6.2 liter LSA V8 with 580 horsepower from the factory. This B5 S4 has a GIAC Extreme E85 tune, FrankenTurbo F21 hybrid turbos, water-meth injection, Evolution Racewerks intercoolers, three inch downpipes, and Integrated Engineering connecting rods. The setup sure works quite well. ...

Here is the RDsport exhaust for the F10 M5 with the S63TU V8. This is a full exhaust system going all the way from the turbos back with downpipes, x-pipe, and a rear section. The system looks pretty good, not the prettiest BimmerBoost has seen, but the appearance is solid. The pricing on it does not make it much of a value with retail at $8,028.00 with an estimated 8 hour install. 8 hours to install this? Really? How many breaks is that guy taking? ...

Wow, major achievement here and quite an improvement on what this car was doing previously which already was incredibly impressive. This vehicle previously hit 10.3@133 on stock turbos with full weight. Champion Motorsport gave the car some stickier rubber and the time improved quite a bit. How does [email]9.837@135 sound? On the stock turbos? With a full weight car? Well, to PorscheBoost that sounds absolutely incredible. ...

Very impressive results here from a completely stock E550 coupe. The M278 4.6 liter twin turbo V8 is looking more and more impressive powering this particular vehicle belonging to BenzBoost member nawlinstornado to a 12.428@115.13. That elapased time was achieved with the factory runflat Continental tires and no limited slip differential. The 1.961 60 foot can be improved tremendously with some real drag rubber meaning low 12's are realistically in this cars future stock. ...

Nice race here with a strong B5 S4 going up against a bolt on C6 Z06. The Z06 is a quick car in stock form and this particular car is modified with bolt ons including an intake, tune, and full exhaust including headers. Depending on how aggressive the tune is and the fuel it is running the C6 Z06 can be putting out in the ~500 wheel horsepower range on a dynojet. Definitely a stout car on the highway especially with its fairly light curb weight. ...

The new CLA45 AMG is a very exciting entry level vehicle that is going to be a big part of the Mercedes-Benz AMG tuning scene and BenzBoost for years to come. With a 2.0 liter turbocharged and direct injected M133 four-cylinder pushing 26 pounds of boost stock producing 360 horsepower sent to all four wheels with a 7-speed dual clutch transmission this car is something of a German Evo. Obviously offering far more sophistication, luxury, and technology but without the boy racer aspects. ...

Well here is an early gift, the upcoming 2014 Porsche 991 Turbo captured completely undisguised with no camouflaging body pieces. The car is not set to officially debut until the Frankfurt Auto show in September of this year but the car looks completely production ready here. Porsche is likely just waiting for the next big show for the official debut and wants to do it on their home turf in Germany considering what an important model this is. ...

The new 4-Series in production form for the F32 coupe has been posted thanks to leaks which has led to production based renderings of the upcoming F33 convertible/cabriolet version. The F33 convertible is going to come four months after the F32 coupe with production scheduled to start in November of this year. Unlike the F32 the F33 will be available only in rear wheel drive form for the 428i and 435i, no X-drive all wheel drive. ...

Here is another BMW M Performance Power Kit from BMW which really amounts to a quick cash grab. Basically BMW just gives you different software they already have sitting around for an extra $1100 plus installation which is something dealers are going to love. Horsepower goes up from 300 to 320 horses and automatic models gain 32 pound-feet of torque while manual models get only a 17 pound-feet of torque increase for a total of 317. ...

It seems the new Mercedes-Benz CLA has everyone scrambling for a competitor. Audi launched their answer which is the entry level A3 sedan and Volkswagen is now rumored to get into the mix with a Golf CC. There is no official confirmation of this and it is simply a rumor but renderings surfaced of what such a vehicle may look like. From a business standpoint it makes sense as the car would be lighter and sportier than the Passat CC as well as come with a cheaper price tag. ...

Here is the updated Porsche 911 RSR based on the 991 generation. The car quite simply looks beautiful and like one should move out of its way. The car is larger than the predecessor although the new roof and shape gives it a lower center of gravity. Weight distribution is also improved with more weight on the front and less on the back thanks partially to the engine placement moved further up. Carbon fiber is everywhere from the wheel arches, doors, wing, boot lid, center console, etc. ...

The 3.0 TFSI is very tuner friendly due to how Audi controls the boost with the ECU thanks to the bypass valve design. This also means Audi can detune the motor very easily as they did for the Q5 which for the 2013 model year gets the 3.0 TFSI supercharged V6. It has "only" 265 horsepower and the SQ5 which has the exact same motor gets 354 horsepower. Well, in comes GIAC with their software to give the standard Q5 3.0 TFSI a huge bump. ...

Nice comparison here between a W204 C63 AMG and a Cadillac CTS-V Coupe. Both cars have the same sized motor with the C63 having a 6.2 liter M156 V8 and the Cadillac CTS-V coupe with a 6.2 liter LSA V8. The difference being that the LSA V8 has a supercharger in addition to the displacement while the C63 is naturally aspirated or "all motor." From a roll, the CTS-V simply shows its power advantage and pulls away up top. ...

Great run here showing an E82 135i with upgraded turbos, full bolt ons, Alpina trans flash software for the 6-speed automatic transmission, meth injection, and a tune from Bren Tuning against a C5 vette with a built LS6 V8. The 135i makes easy work of the C5 from a roll that is stated to have a built motor although what it is putting out is not reavealed. A built LS6 V8 without any forced induction won't have many advantages other than that of longevity over a stock LS6 with the same modifications. ...

Is this the Porsche Macan? A very good question and hard to deny the picture looks authentic and follows the design the latest spyphotos were pointing towards. The front of the car has the exact same LED placement that the spy photos showed as well as the shape of the headlights. The front bumper is also the exact same. Unfortunately, it seems only a shot of the front of the Macan was leaked and there is no leaked rear photo. ...

This is a rumor that does not seem to want to die but apparently it has some legs. In September of last year VW CEO Marin Winkerkorn stated that the VW Group would not be making any more acquisitions and instead would focus on its core brands. However, today we learn that Audi CEO Rupert Stadler and FIAT CEO Sergio Marchionne are in talks regarding a major deal according to private sources although that is not official company confirmation. The question is, will this rumored deal be Audi's acquisition of Alfa-Romeo? ...

The TPC Racing turbo kit is a very popular upgrade for the Boxster and Cayman. It's really the main forced induction kit out there and offers large gains. Well, for one owner the standard power wasn't enough. With just the TPC turbo kit the 987.2 Boxster will put out in the 415 horsepower to the wheel range. With meth injection, TPC was able to boost output into the 470 wheel horsepower range. Then on top of this a 40 shot of nitrous was added. ...

This is a rather interesting development in the turbocharger market. Mann+Hummel worked with BMW over the past four years to develop a functioning prototype using an N54 turbocharger as the basis for a high grade thermoplastic turbocharger housing. The benefits of high grade plastics in cars are numerous but they are usually applied to body and chassis components and not actually to engine components where strength is at a premium. ...

Here it is, the new Audi S3 sedan (8V generation). This vehicle will be poised to compete with the new Mercedes-Benz CLA class. The drivetrain of the car is shared with its S3 hatchback sibling. That means a 296 horsepower 2.0 TFSI with power routed to all four wheels with a 7-speed dual clutch S-Tronic gearbox. A manual transmission is also available which is great news for performance enthusiasts and hopefully will also be offered in the US market. ...
