Jack Olsen built a Porsche 911 to drive every day and conquer Willow Springs

Almost two years ago we wrote about the 12-Gauge Garage Jack Olsen built to house his multifarious Porsche 911 - its 1972 bodywork hides four decades of Porsche parts, like the transaxle from a 1977 911 and the engine from 1995 911, for example. It weighs 2,400 pounds and has 272 horsepower, and Olsen uses it daily driving and for track days, the latter excursions featuring homemade, bolt-on aero parts. German magazine Auto Bild stopped by Olsen's house to look in on the Porsche called "Black Beauty II," and we get a few more details about the mods he's made, like swapping out for fiberglass body panels and welding Fuchs wheel centers to wider Corvette barrels so he could run different tires. Most importantly, though, Olsen divulges his passion for lowering his lap time at Willow Springs. Randy Pobst set the lap record for a production car around the 2.5-mile Big Willow track in a Porsche 918 Spyder at 1:23.54 during a Motor Trend test (the outright record, according to Willow Springs, is held by Michael Andretti at 1:06.050 in a CART car). Further down the list, Steve Millen drove a 415-hp 911 GT3 RS around the same track in 1:33.14 - a car 600 pounds heavier than Olsen's. Over the past 14 years of tinkering with his car, Olsen says his data shows his lap time is now down to 1:26.88, achieved on the day of filming the Auto Bild video. That time would put him in between the 1:26 flat posted by Dominik Farnbacher in a 608-hp Dodge Viper SRT-10 ACR and the 1:28.93 put up by Pobst in a 400-hp, 991-series 911. You can hear Olsen tell it in his own words in the video.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

Supercar 'Holy Trinity' raced at the track, drag strip, and to 186 mph

There was a time when we weren't sure if we'd ever get the Ferrari LaFerrari, McLaren P1, and Porsche 918 Spyder on the track together. Now, we've have a multi-part series dissecting how each supercar approaches all kinds of go-fast tasks. Supercar Driver (SCD) looks at their performances around the track, on the drag strip, and on a runway. SCD didn't get any help from the automakers, it used three cars all owned by one British gentleman, Paul Bailey. The first video has British Touring Car Championship driver Mat Jackson running all three around Silverstone. The second video takes the coupes to Santa Pod Raceway to run the quarter-mile. The third video runs them out to Bruntingthorpe Airfield for a drag race to 300 kilometers per hour (186 mph). We found that latter video especially interesting because SCD shows a graph of how fast each car hit speed marks, and it's interesting to see where the winner made up all of its time and the where the third-place getter lost its time. Nota bene, the McLaren is using its fly-paper sticky Pirelli P Zero Trofeo R tires. You'll find the first video in the series above, the second two videos below. If you still haven't had enough, then check out the Hyper 5 three-part series by Alejandro Solomon filmed at California's Thermal Raceway, starting with the Holy Trinity and adding the Bugatti Veyron Super Sport and Pagani Huayra. Chris Harris also did fantastic work around Portimao with the help of Marino Franchitti and Tiff Needell, with assistance from the factories. This content is hosted by a third party.
