You develop Porsche’s racing program in the late sixties, rewriting their racing history from race to race, win to win. Your team is developing faster and wilder racers, putting you in reach of the company’s first Le Mans outright victory. So what do you do when you are handed the responsibilities of developing the company’s new entry car platform? If you are Ferdinand Piëch, grandson of Ferdinand Porsche, you jam the biggest racing engine in it that will fit.
I finally decided to give in and buy a German made car. Perhaps it’s the clever marketing that captured me this time, but I want to believe it was the clever engineering that drew me to the 2016 MKVII Volkswagen Golf R. While some of the rivals in the segment (WRX STI, and discontinued Evolution) have used the same stale drivetrain for several generations, Volkswagen has taken a different route and the result is a modern drivetrain package consisting of a direct injected turbo four-cylinder as well as a refined double clutch transmission and torque vectoring AWD system. This most recent addition to the MotoIQ project car fleet is a real wolf in sheep's clothing, and in this article we will take a look at some of the cool features of this project car.
When thinking of the 24 Heures du Mans that takes place at the fabled Circuit de la Sarthe, Gainesville, Georgia is not the first place that comes to mind. Even though Georgia may conjure associations with the Petit Lemans, a 12-hour enduro that takes place in the fall of each year at Road Atlanta, the storied French endurance event and metro-Atlanta aren't exactly synonymous. Those who fail to make the association between Mulsanne and Gainesville Highway are overlooking a crucial part of Ford's GT racing history, as this is where you will find the current home of Robertson Racing.
The good old stock SR20DE in our Project G20 Racecar has been doing yeoman duty, reliably lasting for the last few years racing in the MotoIQ Pacific Tuner Car Championship and doing many for-fun track days. The stock SR20DE in our Project G20 Racecar came from a Japanese engine importer and has never been opened up, other than to add big cams back when we used to run the car in N/A trim. For the past three years the engine has been turbocharged which has greatly increased the strain it's experienced.
How do we become better at driving? Practice makes perfect, right? Well not necessarily. Without feedback and direction, additional practice won’t always improve your ability and can possibly lead to the development of bad habits. So in reality, perfect practice makes perfect. In Part 2 of the Driver Development series, we discuss how drivers learn to improve their craft through various methods from coaching to data analysis to simulators which all aid in the advancement of the skill of driving.
As luck would have it, the girlfriend had to work out of town and the semi-local track that we do all of our testing for the Professional Awesome Evo, Gingerman Raceway, was hosting a weekend track day. This would be the perfect opportunity to take the Miata, with or without her knowledge, up to the track. With tech and driving support from PA Motorsports owner, Grant Davis, it looked like the perfect opportunity to take the car around this wonderfully challenging racetrack to get some data on what the Miata could do. With the roll bar, seats, brakes and cooling system ready to go, it was also a great time to track test these systems to ensure everything was up to snuff and baseline the car for future improvements.
We gave our M3 a quick and easy bump in power by swapping out the factory air filter for the industry-leading High Performance K&N air filter. We have seen some impressive gains from K&N products and feel there’s no reason you shouldn’t have one on every car you own! But how much power can really be gained over the OEM BMW air filter in this highly stressed and finely tuned 8,250rpm screaming V8? Read on to find out!
Do you want to see a future Formula Drift Champion? Look no further than Alec Hohnadell. At only 20 years old, Alec already has 3 seasons as a pro under his belt and is the youngest driver in Formula Drift.
From coolant to cabin temperatures, Vipers are notoriously hot due to having one of the largest engines ever stuffed inside a sportscar. To combat this problem we turn to the thermal insulation experts at HeatShield Products to keep the heat in the exhaust system to lower the temperature inside the cabin and side sills. Hopefully we will prevent our side sills from discoloring and burning our legs when getting in and out of the car without proper clothing and ingress/egress technique.
We've heard that a good set of harnesses can make a difference in lap times, but who wants to go through the ordeal of figuring out where to anchor them and cutting up a car's interior to install them, only to lose the use of the back seats? We test out Schroth's solution with their Quick-Fit Harness system.
There aren’t many more usable vehicles than a Subaru Outback (Scooby Vapewagon). Mild off-roading to your next rock climbing trip? Easy-peasy. Need to take your Australian Cattle Dogs to the vegan dog park? Donezo. Hauling your butch friend Karen and all her camping gear to Beaver Island for a weekend under the stars? Legally, only Subarus are allowed to perform that task. Yet with all these wonderful positives, there’s one annoying issue that nearly makes all these points moot, over time Outbacks can develop terrible rear bump steer (totes gnar dorifto).
Today we get some preliminary testing of the Precision CEA 6870 Gen2 turbo both on the dyno as well as on the tarmac! If you like dyno charts and speedo videos, check this out.
There aren't a lot of off the shelf parts available for a Nissan Juke. In part 2 of this series Lars Wolfe fabricates or adapts many parts and updates the shifting pattern to get Opy further race ready.
