The weight of the truck has nothing to do with HP period. What is a rule of thumb is every 100 lbs. of weight reduction is good for .1 drop off your E.T.

 

I think this thread has gotten off track a little but it really needs to be a call out for everyone. Kind of give everyone an opportunity to explain the reason they are so heavy compared to others. I have no mods other than heavy *** tire and wheel combo (96lbs. each) that slowed me down a full second in the 1/8 mile. A tool box with a few things in it that weighs probably about 100-150lbs. And two 10" woofers in truck boxes and a amp. Id guess they weigh about 50 lbs. combined. Maybe a little more. Talking about a dog!!!! When I weighed mine it was right over 5100 with me in it at 180lbs. RCSB 4X4

 

I dug this out of a box and learned how to use my scanner.



I edited my previous post from 5760 to 5740, my memory was off a little. To those who have the really low weights posted, congratulations on having lighter trucks. I have not done anything to lighten mine, in fact, almost everything I've done to my truck has made it heavier. To those who still don't believe a 1/2 ton 4x4 can weigh this much, I don't know what to tell you. I like my truck the way it is, and really, that's all that matters.

 

As to EVILGMC's sayin 100# being worth 10HP @ wheels. I know the gains realized on rotating mass are best when it's taken from wheels/tire. Unsprung right? It helps handling too. MPFD I do agree w/. 100# = .1. Not where someone said his bro goes on a import forum & it's worth -.25 reduction. That's ricer math.
Unfortunately, I haven't done any wtg. reduction, only added.

 

The one Ive always heard and seems to be true is that for every 100lbs you drop, you pick up a tenth. My buddies 374 Trans Am was running solid 8.95s in the 1000. We pulled about 350lbs out of it in misc. BS and the very next weekend he went 8.61 on the exact same setup with almost identical conditions.

 

2000 RCSB 2wd 5.3/4L60E was 4100 with half a tank without me in it, that was with bedmat, spare no weight reduction at all.

 

I just weighed mine today...the tahoe with 24s and my system in the back, tank on E and me in it (180) I was at 6080 lbs..id like to see what i would run without the rims and system, and some weight reduction with the 6.0 and converter

 

I've also heard that every 100 lbs is a 1/10 second. Don't know how accurate that is though.

Apparently according to this thread somewhere between 3900 and 7500 pounds. lol

 

I guess I should have read the very last page. my bad, but yea I agree.

 

My 2004 Silverado SS - AWD weighs 5220 with a 1/4 tank of gas. This doesn't include my weight. Truck has a magnacharger, shorty headers, and corsa catback. Spare tire and mount is missing. Has (2) 12" woofers inside a 3/4" mdf box. Stock otherwise with exception of drop in bedliner.

I weighed it on certified truck scales. The same scales I've been using for years. Between my friends and I, we've probably weighed 20-25 cars. The weights have always made "sense". In other words, were in line with what those cars were supposed to weigh, etc. Also, when I weighed my mustang back in the day, I had been to the track many times, had also put it on a dyno several times and all of the numbers seem to match up perfect when it came to the performance calculators.

Hope it helps, good discussion.
