Thanks for the posts. I did run slot cars and have used the lexan stapled to the front on a slot car dragster. I have one taped to my high speed body right now. I may be able to put my collapsing rear spoiler back on if I use the front piece. It will collapse as well. I have some problems with the new wind machine that may be solved by raising the plate up on little pedestals. I think it needs wind flow below the plate or the plate lifts all by itself with no car. I did not seem to have this problem with the previous setup.
I did some more experiments behind the car. Over the tires the air flow is stagnant at the back. The impeller goes forward slow then backwards slow. In the center top there is up to 1.8 mph into the car body. The airflow out is indeed there but it is down low. I get a good jet down there with no front soft dam.
