As an aside, I think it's time for the AA/FD crowd to start considering a full bodied car with a second engine to suck the air out from the underside. Or, has the NHRA foreseen this and banned it? That would be typical of their stand against improvisation.
Billy, I think that would be a good idea to create a downforce under the car. Isn't Can Am Cars already doing something like this with air channels underneath etc?
Trust me, doorslammers at times can benefit from rear spoilers or wings. I have busted loose many times at the other end and that was years ago. just two little wedge shaped spoilers made a huge difference for me.
I think that mostly what we are now seeing in drag race door slammer spoilers is creating more of a Kam Effect than it is a rear downforce.
