A dyno day is the one chance where people get to see if their bragging is backed up by actual facts. You claim your car makes 800 horsepower, but when it says you make 200, it’s a real kick in the ass. Mr. Regular just went to a dyno day to see what it was really like.

What he found was the definition of madness. There were people in the streets. Burnouts all over the place. Cars nearly falling off the dyno. And a vagrant that somehow appeared and disappeared without a trace.

And that wasn’t even the craziest part. Here’s everything from Mr. Regular’s dyno day.
