??? So you would race a car for a full year with what....a Dinan tune and a bottle of water for the cockpit? I don't think the modification of the turbo was solely to create horsepower. It's one thing to tune a car to drive around the street, its another to race it for 24 hours. No doubt the car was modified for the race track. Not with standing all that, it seems to be fairly resilient. The early N54's had their issues.
