The factory-backed Porsche RS Spyders of Penske Racing have been leading the ALMS LMP2 class and even captured some overall victories this year. In the competing (well, kinda) Grand Am series, the official Porsche engine in the Daytona Prototype class is a 3.8-liter flat-six. The Spirit of Daytona team, however, wants to take a different approach.

It had the Lozano Brothers build a five-liter race-prepped version of the Cayenne V8 that they intend to debut at the series finale at Miller Motorsports Park on Sept. 15. Since Porsche hasn't officially approved the project, it won't allow the team to carry Porsche badging on the engine. Instead, the car will be labeled a Fabcar-Cayenne in its first run.
