Pete the added weight is 76 pounds (.07 seconds) If I lost 100# the added gain is .10 seconds, I would still be up .03 seconds. End result instead of running a 12.0 flat, It is a 12.2 car. Not even remotely fast by any means.
Device used was a SPL LAB PRO.[/QUOTE]
Bob, I like your thought process about this. Also only race cars down hills and jack up the rear so that your Z is perpetually going down hill. It will be faster and offset the weight added. That is what I would do. LOL
Just kidding of course......
You mentioned hearing loss.... you aren't kidding, I had to stop at Wally World to pick up some ear plugs driving home. I already have ringing in my ears from flying helicopters.
