Oh Boy! Do I love hillclimbs!
What is interesting though is that the red car is NA, I thought all the M1 Pro-Cars were turbo charged. So either he removed the turbos or that is a M1 with the body kit of a pro-car.
The green car sounded NA as well, but it looks a lot faster.
Can't get youtube to translate the German, it thinks he is speaking Dutch. But the guy said it is an eight cylinder, so I'm guessing he mis-spoke or he doesn't know much anyway.
Either way, that engine sounds amazing!
