Finnish Time Attack Champion Sami Sivonen is on a quest to built the fastest Time Attack race car on earth. It started when Sami purchased an unregistered first generation Audi R8 track car from Germany. Then his talented team lead by Team Engineer Jyrki Repo spent nine months in a single garage to create the R8 1:1 race car<\/a>.<\/p>\n

Sami and his team call the project the R8 1:1 because it produces the same amount of power as it weighs. The previous engine was a 5.0 L V10 from a Lamborghini Gallardo which made 1,220 horsepower to the rear wheels on 1.4 bar (20.3 psi) of boost. However the engine made more than that on the track going as high as 1.6 bar in 5th and 6th gear. Based on fuel consumption (11 liters per minute at full throttle) it was estimated to make closer to 1,550 crank horsepower. You can read all about how they built the car and original engine here<\/a>.<\/p>\n

After pulling apart the 5.0 L V10 for scheduled maintenance they found the crank was bent and the block cracked. Since the 5.0 L block is no longer produced it made no sense to purchase another one since it possible suffer the same outcome. They decided to switch to the newest generation 5.2 L V10 which is much stronger design. Audi designed the engine with bigger bearing journals, block is 2 mm thicker between cylinders, and it doesn’t contain split conrod pins.<\/p>\n

The team doesn’t plan on pushing this motor any further than the previous. You can expect the same boost coming from the twin Garrett turbochargers and MoTeC M150 ECU. Power goes through a Holinger LG6 sequential transmission with pneumatic paddle shift. <\/p>\n
