Many say that the new M2 is one of the best driving experience vehicles BMW has released in a long time and we do agree. Driving the car stock for about 6 months we were very pleased with how well it performed in most aspects from handling, braking, and overall drive-ability. The one area we felt the car lacked a bit was in the power range department. The car is not slow by any means in stock form but once over-boost cuts out it dose falls short a bit in the top rpm range. We knew Dinan was working on a stage 4 upgrade for the car and could not be more excited when the call finally came in saying its ready to ship.
Installation was what you would expect it to be coming from a company like Dinan. The intercooler, intake and exhaust fit is spot on and the turbo is a factory unit just machined about 30% larger so it fits just like the OEM unit would. As a matter of fact once installed there would be no way to tell the difference unless the cold side wheel is exposed. The Dinantronics unit is the main brain to this all controlling all aspects of the additional power while maintaining a safe median to certain parameters such as fuel trim. The unit is also blue-tooth enabled so once an app is download onto your phone you can set the vehicle to a stock mode in the event a trip to the dealer is needed.
Minimum weight and maximum sound are the name of the game. IPE’s Stainless and titanium exhaust system consists of IPE’s trademark Valvetronic muffler/s with tips. They use original quality actuators to control the valves improving reliability long term wise. Their GT3/RS titanium exhaust is a super lightweight weighing in at only 12.17 kg. That’s a weight reduction of 53.1% when comparing it to the original weight of the stock system which weighs 26.0 kg, a weight saving of 13.83 kg. The exhaust valves make it possible to improve both torque and horsepower, while the muffler internals were designed to specifically attack power gains and create their trademark F1 sound. IPE is famous for performance and F1 sounds at its finest. Their new lightweight titanium exhaust for 991 GT3/RS opens up entirely new worlds on these cars, any passionate driver who is looking for that extra-kick should consider refining their car with a system like this. ** Note ** Shown in pictures is IPE’s stainless system.
This E39 BMW M5 came in for the works and it sure got it! We started off with the heart of the beast the S62. We striped it down to its core and lightweight up the internals a bit to help it rev much faster. We then helped the top end flow air better by performing some custom port and polish work and mated it with some more aggressive shrick cams. Some of the bolt on engine parts included Dinan’s complete S2 package: Carbon intakes, larger maf housings, ported throttle bodies, shorter/larger velocity stacks and oh.. a complete race header. Other modifications includes Dinan’s lightened dual mass flywheel and a 3.45 limited slip differential. With all this extra hp we knew we would need to improve the handling and braking characteristics so we went ahead and installed a KW V3 kit and Stoptech front and rear big brake kit. The overall package coming all together really has made this M5 the ultimate driving machine.
This stunning Porsche GT3 RS has worked its way to us from across the globe. It has been on many of the worlds greatest race tracks including Fuji Speedway’s F1 track in Japan. Our job is to keep the vehicle running right when put to the test. This time around we did a much needed engine service, sharkwerks coolant upgrade and clutch/flywheel replacement. This is one of the many GT3/RS that we service for owners both near and far.
Dave’s 2005 Audi S4 came in for intense vehicle makeover. We performed a complete timing chain service on the vehicle which is a MUST needed service on these vehicles. To help make some more HP we added a VF-Engineering Eaton TVS1900 supercharger system (inter-cooled). To help the vehicle handle the road better with the extra power we went ahead and installed a Bilstein Pss9 coil-over system. Finally to help stop the beast nothing but a Stoptech 6 piston big brake kit to do the trick. The car was also completely corner balanced and dialed in with our Hunter Engineering Alignment system.
In today’s world there is an ever increasing expectation by the driver regarding quality and smoothness. Many vehicles like BMW, for example, are known for their superior ride quality and handling. Consumers are looking to have the best looking vehicle and to not compromise or lose any of its handling characteristics. As a result, wheels are getting bigger while the actual tire sidewall is getting smaller or thinner. Suspension components are now made of lighter metals, such as aluminum. This all leads to less “cushion” in ride quality so the driver tends to feel a lot more than they ever used to. Any imperfections or problems are more noticeable now than they ever used to be. So what is a road force balance and why is it needed?
Road Force Measurement is new to the automotive service industry. This new measurement identifies tire and wheel uniformity. Road Force can be used to solve uniformity related tire and wheel vibrations. Tire/wheel assembly uniformity can only be measured under load. This is especially needed these days since most car manufactures are going with such thin sidewall tires and/or run flat tires, which are very susceptible to causing a vibration while using your vehicle.
The load roller on our Hunter GSP9700 performs a computer simulated “road test”. It measures the tire/wheel assembly to determine how “round” the assembly is when rolling under a load. It does this by allying force up to 1400 pounds against the rotating tire/wheel assembly as it performs its measurements. If a tire were not exposed to the road surface, then balance would be more than sufficient. However, this is not the case. An egg-shaped tire/wheel assembly can be balanced about its axis, but an egg-shaped tire/wheel loaded against a surface would not give a smooth ride.
