I decided to turn up the boost on my Nitrous Fri night.... didn't work out too well. I did a fair launch, seemed to go pretty good. I looked over at the Display at the finish line, saw 12.7 @ 111 mph. Then I looked in my rear view mirror and saw nothing but smoke billowing out the entire back of the car. The track guys pulled me off to the side of the track but it was too late, I laid down antifreeze down half the track. It took them 45 minutes to clean the lane and re-open the racing. I've been slowly turning the boost up with my aluminum heads. The head gasket let go in the front of cylinder #1 and emptied my coolant system on to the track. My buddies watching said it was a Hell of a show. Oh, well, gave me something to do this weekend.
