The bumper weighs 38lbs. I have run 95% of the time with it on. I have not run back to back to tell if it helps. All my best times were in -550 to -1200 DA and I had the bumper off. Times were 11.17 & 11.18 on different days.
I have run 11.346 @ 117.63 mph in regular air and cut a 1.575 on ET Street drag radials, with the bumper on. Fact is though, the bumper and sway bar is almost 80lbs off the nose, so it has to help some.
I made an excel spread sheet today, logging all my runs since Jan 03, 2009. Pretty cool looking at everything all together.
Wheels are Chevy colorado spares. They are still heavy at 36lbs, tire\wheel.
Next tranny will be the upgrade.
...If this doesn't get resolved, I'm sending it to Jersy...Tomthecarguy. Very experienced in these tranny's

Pitt, what about FLT or PB for trans? I was gonna ask when hood's comin off for more weight reduction, but dug beat me to it.
sixltrbtr asked what rear tires are you running? I know u said they're Hoosiers, but what size? Also, what size M&H skinnies for rubber up front?
quicksilverado, your salvage yard $850 w/.~ 25k miles on it was a nice find. I'm impressed even more u put ~125k more on it before it started slipping in 2nd some in your truck. Nothin more than stock spec rebuild by a friend w/. only a shift kit and vacuum mod handles 10 sec. times. Wow, those 80's are tuff.

You obviously know how much stuff weighs, so since the F bumper is 38#, I'll guess the Rr bumper is ~ the same. I figured bumpers were 50#, so I wasn't too far off. I wanna do away w/. rear bumper 1 day, even tho I don't run your times. Too bad it's off back of my truck tho, not the nose. My only concern is winter drivers tappin my back end w/o a bumper. I have to figure that out when time comes. Also, w/. my tonneau out back, I could put a pan on to save wtg. where the tonneau lid adds 110# over tires. So, say 110# - 38 = +72# net gain. I use my lid, but I could take off @ track if needbe.
