to glue or to weld?

having ask this question before myself, I have a neighbor who races a firebird. He is pulling close to 1100 HP. He didn't weld his pans in. He used an adhesive and self tapping screws every 2 inches around the floor pan. Definitely not saying this is how to do it, but I've seen him at the drags multiple times with no issues. My Barracuda came with a 235 HP motor so it seems that would be adequate. When I brought this up a while back, I kind of got a lot of negative responses.
Just a thought.
