…It’s Tuner Tuesday: Porsche 911 GT3 RSR?

911 GT3 RSR Front

The 911 GT3 RSR is what happens when Porsche puts no limits on the things it can do in the name of speed.

Designed to be a pure race car, and built to run in the American Le Mans Series, the Nurburgring 24 Hours, and the GT2 class at international long distance races, it’s based very loosely on the 911, though you won’t find many parts in the GT3 RSR that you could swap between it and the 911s you see prowling the golf course.

Seriously though, when changes from the previous GT3 RSR include “a lighter wiring harness to further improve handling” you know things have gone from intensive to excessive.

911 GT3 RSR Engine

The 4.0-liter, six-cylinder boxer engine makes 450 hp at 7,800 rpm up to a redline of 9,000 rpm, and a new multi-funciton display located above the dashboard indicates the optimum moment to change gears, if you can’t already tell from the engine screaming at you 9,000 times per minute.

How about a programmable multi-function, onboard supply system control device, giving teams the choice of many individual functions, including an infinitely adjustable blinking frequency of the lights in the front apron, which helps to immediately recognize race cars when they enter the pits in the dark. For easier service under race conditions, the car even features an air-jack system with overpressure valve to life it in a pinch.

Only 20 of the new GT3 RSRs will be built, but at a price of $500,000, it shouldn’t be surprising why. Speed costs, and in the case of the GT3 RSR, you’re buying quite a bit of it.

…It’s Tuner Tuesday: V12 Mazda Miata?

V12 Miata

The Mazda Miata was designed to be a grown-up’s go-kart that could out handle just about anything else on the road, and it did a pretty good job at that task. However, some people are just not satisfied with enough, and are always looking for more.

In this case, more came in the form of a V12 engine out of a Jaguar that one enterprising Miata owner decided to shove between the front wheels of his Miata to see what would happen.

Sure, it’s not pretty, and twelve carb intakes poking up through the hood are sort of a dead giveaway for the fact that this is no ordinary Miata, but isn’t that the point when you’re building a project like this?

Check out the vid for a walkthrough of the build, as well as the sound of the monster as the owner fires it up for the first time:

…It’s Tuner Tuesday: Lotus Eco Elise?

Lotus Eco Elise

How do you take an already feather-light supercar and reduce the weight by more than 70 pounds?

Easy; just make it more environmentally friendly.

Lotus decided to make an Eco version of their venerable Elise, and in the process, managed to reduce the already svelte curb weight.

Changes include a collection of sustainable materials for the body and trim, including hemp, eco wool, sisal, and a new, high-tech, water-based paint that can be applied by hand and can still achieve the fantastic finish you’d expect from a car of this quality. The new pieces and parts manage to reduce the Elise’s environmental footprint throughout its lifetime, as well as limit the amount of energy used during its production.

In addition to the new materials, Lotus has also added a flexible solar panel to the roof that helps power the electric system (less strain on the engine means better efficiency) and added a green shift light (hopefully in addition to the regular, ‘you’re about to blow up your engine’ red shift light) that helps drivers achieve the maximum fuel efficiency while driving the car.

Thankfully the engine and chassis are still the same, and Elise has actually managed to improve the performance by reducing the weight, so you’re still getting one of the best handing cars on the market out of the deal, but if you’d like to save a little Earth while tearing up a little track, the Eco Elise might be just the car you need.
