There are so many videos on Youtube, it's amazing. I have a question, I was watching an injected FE dragster fire up and head to the line (I think it was the Woodburn video) and it looked like after they fired the motor, a crewguy put a cover over the stacks, kind of like what you would use to keep stuff out when the car is parked. But the driver headed to the line that way. Any idea what that is for? Is it maybe screened on top?
