Physical health is key for any athlete’s performance. The same applies to anything mechanical, such as the Audi B9. Just as our bodies have defenses against sickness, the B9 S4 and S5 came equipped with a robust system to mitigate the effects of blow-by. However, as we went over in our last post, this separator might need some backup.
When we last left off, our in-house fabricated prototype made its way onto our donor S5 and was ready for our standard 1000-mile road test. This test provides us with a benchmark on the rate of blow-by collection while also being the final check against any dreaded check engine lights.
