Lower front air dam removal.
I was thinking about this a little today and remembered John Lingenfelter taking the side mirrors off his LT1 bird for top speed contest back in the day. Has anyone tried this for drag racing? Should be easy enough to take off and tape over the holes. I'm going to try the taped front end, air dam, hood seal, and mirrors in the spring to see if I can bust 130mph with a cam only LS6.

Sure, whatever the theories are, you achieved a 2mph gain which is good.
If I get around to it next year I'd like to do some aerodynamics work on my car as it is a brick shaped object from 1968. I had planned to do some 100mph coast down accelerometer and speed tests to see what drag I'm actually getting then add a lower air dam and other things and see the difference.
There a probably large gains to be had on my car as it was designed before aerodynamics were of interest to auto makers and was not designed for high speed use.

Demonicbird00 > Sounds good ... weight reduction list says the weight savings from removing the rear spoiler from a TA is 35 lbs ... you sure about the weight being 18 lbs? It's a pretty big piece of material for sure. A little backdraft never hurt the NASCAR boys, so, sounds pretty reasonable to me for drag racing. Of course, I'm sure it becomes more important to them at 160+ mph. I'll try that next time out to the track ... just waiting for it to open back up in a couple weeks.

(They were apparently exported to the USA, but I imagine they were rare and easily forgotten)

nah ive never done back to back comparisions..... im at the point now where when i go, i dont wanna waste passes persay. but a good comparision would be to do this small stuff to a near stock or bolt on car.
yeha its def 18lbs, i weighed it as i do w/ everything that i take off the car.

P.S. Often while cruising along at 170, I wonder how my air dam is performing.
Sorry, time for beer.
