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.

Porsche resurrects V8-powered 911 prototype from the Eighties

These days, we take it for granted that the Porsche 911 uses a flat-six engine. That's because every version of the iconic rear-engined sports car has had one. Right? Well, for the most part. There was the 912 that joined the original in the late Sixties with a flat-four. And in the mid-Eighties, Porsche toyed around with the idea of a V8-powered 911.
After the first-generation 911 had been in production for over two decades, Porsche began development of its successor, the 964, in the 1980s. And one of its ideas was to use a V8 engine. So it took a 964, borrowed a V8 from Audi, gave it the rear bodywork from a 959 and dubbed it the 965.
The idea was to create a more affordable successor to the 959 that included its advanced all-wheel drive system and active suspension. The Audi V8 would have been replaced with one of Porsche's own design - possibly based on the it had built for Indy racing - but Dr. Ulrich Bez (who was then head of Porsche R&D long before taking the reins at Aston Martin) ultimately killed the project.

UPDATE: Porsche could raise its stake in Rimac, and Rimac weighs in

CLARIFICATION: An earlier version of this Reuters story said Porsche could raise its stake in Rimac to nearly 50%, but Rimac reached out to Autoblog to say that's not so. Here is a statement from Mate Rimac: "We have a very strong partnership with Porsche that is key for Rimac Automobili. Porsche is a shareholder in Rimac since 2018 with 15.5% ownership currently, accumulated over several rounds of investment. While it is true that we are discussing further expansion of this collaboration that will lead to increase of Porsche's stake in Rimac Automobili, some media have mistakenly reported that Porsche would take over 50% or nearly 50% of the company.   We are very happy that the partnership with Porsche will strengthen even further, but it is in the interest of both Rimac and Porsche that Rimac is a fully independent company. We are working with many car companies that are not our shareholders and there is a clear separation between shareholding and projects. It is very important to us that our industry customers have the peace of mind that Rimac is independent and that there is an "Information Firewall" between projects and shareholders (not only Porsche, but also Hyundai and others) - and this will not change. Confidentiality is very valued in the industry and one of the basics for collaboration between companies. Our shareholders are happy with such an arrangement and expect the same level of professional behaviour and confidentiality for their projects and customer projects.   So, the point is: Porsche's stake will increase but nowhere near to 50% and Rimac will remain independent with many industry customers that are not our shareholders/investors." The original story, with the 50% reference removed, appears below.   FRANKFURT — Volkswagen unit Porsche is participating in a financing round of Rimac Automobili that will see the electric supercar maker raise 130 million-150 million euros ($157 million-$181 million), its owner Mate Rimac told weekly Automobilwoche. The fundraising should be completed in two to three months and another round is planned at the end of the year, Rimac told the trade journal. Porsche owns a 15.5% stake in Rimac Automobili and could raise its stake in a deal that would also include the transfer of Volkswagen's supercar brand Bugatti to Rimac, Automobilwoche said. Volkswagen and Rimac were not immediately available for comment on Sunday.
