Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Magnus Walker and Alex Ross stop by Leno's garage with their 997 GT2

The market is littered with Porsche 911 tuners, with names like 9ff, Gemballa and TechArt leading the field. Seldom do any two ever collaborate on a joint project, but that's just the kind of match that was made at Jay Leno's Garage. That's where Alex Ross of SharkWerks and restomodder Magnus Walker first met, sparking a collaboration that yielded the car you see here. And fittingly, they've brought it back to the garage to show off what resulted. Though Walker usually deals with older Elfens, this time he applied his eye for style on a more contemporary 2008 997 GT2, decking it out with grey stripes, orange bumpers, gold wheels and decals and a tartan-upholstered interior. He left the mechanical bits to Ross and company, who dropped the suspension and increased output to 650 horsepower at the wheels (775 at the crank), surpassing the stock GT2 and even the later GT2 RS. The result is pretty hard-core and old-school, but you'll want to watch the video above to see for yourself.

UK Porsche GT3 owners are irked that other countries are getting better deals

Porsche 911 GT3 owners in the United Kingdom are up in arms, but it's not for the reason you might think. Okay, well it sort of is. See, it's been fairly well documented that 911 GT3 owners have had their cars grounded over concerns that the engines could catch fire. Porsche is rushing to build and install replacement engines in all 800 or so cars, scattered around the globe.
This isn't really the issue. The problem for these British owners is compensation. While the car's have been grounded, car notes still need to be paid. To deal with this, American GT3 owners are being paid $2,000 per month. German owners get 175 euros ($242 at today's rates) per day while a GT3 owner in Dubai is allegedly receiving $12,000 (it's unclear if this is a lump sum or a monthly payment). Basically, if you aren't able to drive your six-figure super car, you shouldn't have to pay for it. Seems reasonable regardless of the make.
British owners, though, aren't being compensated, and for 30 to 35 owners, that's not acceptable. They've banded together and are led by Sunil Mehra.
