More details on Lanzante's F1-engined Porsche 930 restomod

Not long after last year's Porsche Rennsport Reunion, we posted on Lanzante Engineering's restomod project with the original Porsche 911 Turbo. McLaren Formula One used TAG-branded Porsche engines for four years in the 1980s to win two constructor's and three driver's championships. McLaren sold 11 of those engines to Lanzante — nine of which have been raced, one with a win to its credit — and Lanzante is installing them into the original chassis of some 930s. PistonHeads stopped by the shop to find out more. By the end of its service in the MP4/3, the TAG-Porsche TTE P01 motor rang up 1,060 horsepower in qualifying and 960 hp in the race, revving to a 12,600-rpm redline. Porsche engine legend Hans Mezger had led the development, coaxing those numbers from just 1.5-liters of V6 aided by two large KKK turbos at a max of four bar. All that was fine for a time when F1 ran with unlimited testing and unlimited parts, but a modern owner doesn't want to pay five techs to live in his garage and keep his car running. Lanzante asked Cosworth to make the engine more drivable and reliable. Cosworth installed a new crankcase, adjusted the air-fuel mixture, and installed smaller turbos for quicker power delivery, decreasing max boost by 25 percent to three bar (43 psi). The redline has come down to 9,000 rpm, for final output figures of 503 hp and 310 pound-feet of torque. According to PistonHeads, power climbs a "steady incline to redline," and more than half the rev band delivers maximum torque. The 503-hp rating doesn't sound like much today, when a Mustang gets more than 700 hp. Yet the first 930 Turbos got 296 hp and 243 lb-ft from a 3.0-liter flat-six with one big KKK turbo. The most powerful 930 Flatnose worked up 330 hp and 347 lb-ft from a 3.3-liter flat-six. Lanzante's taken out a ton of weight, though. The TAG engine is already 220 pounds lighter than the 930's 3.3-liter; a new carbon fiber hood and engine cover, and aluminum door skins shed more pounds. The total package weighs roughly 2,430 pounds, which is more than 500 pounds lighter than the original Porsche Turbo. That includes the extra pieces needed to make an F1 engine power a passenger car. Lanzante had to swap in a 930 Flatnose front bumper, which replaces the fog lights for oil coolers. The team put radiators at the front of the car as part of a brand new water cooling system. The climate control is entirely electric, because F1 cars didn't come with HVAC.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

Porsche recommits to Le Mans through 2018

Porsche is back at the forefront of sports endurance racing, and it has no intention of leaving anytime soon. The German automaker announced that it will stay in the LMP1 class of both the 24 Hours of Le Mans and the FIA World Endurance Championship through the end of 2018. So its rivals can look forward to a good three more years of heated competition at least. After winning at Le Mans a record 16 times, Porsche dropped out of competition for top honors in 1998. It returned to the front of the grid last year with the 919 Hybrid, winning the 6 Hours of Sao Paulo at the end of its debut season. Its greater victory, however, came earlier this summer when the revised version took a dominant 1-2 finish in the famous French endurance race. That put the team from Weissach in the lead for the World Endurance Championship, which it (spoiler alert!) further extended this weekend with another 1-2 finish in the inaugural 6 Hours of Nurburgring. "Motorsport is an important part of Porsche's brand identity – but not an end in itself. Racing has got to help the technology of future road going sports cars," said Porsche chief Matthias Muller in the statement below. "It was the revolutionary efficiency regulations that convinced us to return to top-level motorsport for the 2014 season. That we have managed to take the crown jewels of endurance racing in only our second year, with a one-two result in Le Mans in 2015 with our highly innovative and complex 919, is an outstanding testimony to the people in the Weissach research and development centre. The competition bears fruits and we see further potential for future synergy between the racing and road car programmes. This is why we have extended the programme." FIA World Endurance Championship (WEC) and 24-Hours of Le Mans Porsche confirms LMP1 programme up to end of 2018 Stuttgart. Porsche continues racing into the future with the 919 Hybrid: The board of Porsche AG has decided to extend the Le Mans prototype programme until the end of the 2018 season. With its ground-breaking concept – a downsizing turbo engine and powerful energy recovery systems, combined with an extreme lightweight design – the racing car with a performance of around 1,000 hp serves as a research laboratory for future sports car technology. Matthias Muller, Chairman of the Executive Board of Porsche AG, said: "Motorsport is an important part of Porsche's brand identity – but not an end in itself.
