Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
Take a look and let us know what you think in Comments.

Auto journalist ordered to pay big money for blowing up Porsche 917 engine [UPDATE]

Racecars blow engines all the time, but a Porsche 917 isn't just a run-of-the-mill racecar. British automotive writer Mark Hales reportedly borrowed a 917 from 82-year-old former Formula One racer David Piper for a magazine article, and mechanical tragedy ensued. Nobody is arguing that the engine failed after being spun to 8,200 rpm. However, Hales was warned not to exceed 7,000 rpm, says owner Piper, and the affair landed in English courts with Piper seeking £50,000 - over $79,000 US - in reimbursement funds for an engine rebuild and loss of use of the car while it was being repaired. Judge Simon Brown ruled in favor of car owner Piper, putting Hales on the hook for £110,000 ($174,000) including legal fees - a whole lot of money in any language.
Hales says the Porsche suffered a mechanical fault while lapping that allowed it to slip out of gear and over-rev. Piper wasn't convinced, and sought to have the repair paid for by the guy who broke the racer, saying "If you bend it, you mend it." It's not like Hales is a novice driver, having seat time in both professional and amateur races over 30 years, notching about 150 wins, but even the best drivers sometimes miss a shift, and that's what Piper contended happened to his car.
According to reports, Hales has had to sell most of his valuables to pay his lawyers and is now facing bankruptcy with the ruling against him. Members of the Pistonheads website are trying to coordinate a collection to help him out, as well.

The 2017 Porsche 911 RSR goes mid-engine, purists be damned

Porsche unveiled its World Endurance Championship and IMSA WeatherTech Championship competitor with the 2017 911 RSR. And this 911 is different from the rest, as the 4.0-liter flat-six engine powering this beast is in front of the rear axle, not behind it. That's right, this 24 Hours of Le Mans competitor ditches the iconic rear-engine layout. Porsche isn't talking specifics on how exactly things are arranged back there. The engine is new, now based on the 991 911's block instead of the previous Mezger motor that's been used for years. The transmission design is new as well – it would have to be to accommodate the new location relative to the engine. The racecar has been engineered to meet the LM-GTE class, where it will go up against other mid-engine cars like the Ford GT and Ferrari 488 GTE. Moving the engine to the middle has given Porsche the ability to fit the 911 RSR with massive bits of aero, like the humongous rear diffuser that looks like it would be more at home on a machine of war. The only thing that can compete with the diffuser for size is the top-mounted rear wing, which shares a similar design to the one found on the 919 Hybrid. Going back to the engine, the direct-injected boxer motor, depending on the size of the restrictor, generates as much as 510 horsepower and sends all of its fury to the rear wheels. The engine is paired to a six-speed sequential gearbox, which drivers can employ through paddles on the steering wheel. The new engine doesn't have a lot of weight to push around as the 911 RSR, as required by regulations, weighs 2,740 pounds. Speaking of weight, the engine layout isn't the only change for the 911 RSR. For 2017, the car ditches its steel body for one that's made out of carbon fiber. The body attaches to the chassis via quick-release fasteners, making the vehicle easier to service as exterior elements can be removed with minimal effort. The racecar also gets a radar-based collision system – aptly named the "Collision Avoid System" – which is meant to limit the 911 RSR's encounters with faster LMP prototypes. Only time will tell if the new layout and aerodynamic components help the 911 RSR beat its competition. But there will be plenty of opportunities to see the racecar in action as Porsche plans to run the 911 RSR in 19 races during the 2017 season, the first of which will take place at the IMSA opener on January 28th at Daytona, where the racecar will make its track day debut.
