I'm adding approx.. 100lbs stereo equipment.. how much would this effect my time on the quarter mile

Frisco

I could be wrong here, (its been a while since I've drag raced) but I believe every 100 lbs is roughly equal to 1/10 of a second

you have to calculate the Sound wave drag effect. that'll take a whooping 1/1000000000000000 of a 1/100000000000000000000000000 of a millisecond
Also the Sub Sonic Boooom effect when the sub hits hard, increasing lift. Easy to counter that, just and a 6'x 3' x 2' foot wing to keep traction from slipping. (some vinyl stickers to cut thru air drag)
Just make sure you add a Flux wave in you stereo's Capacitor, that should boost your 0-60 speed in no time (with 28 miles to spare)

100 lbs = 1/10 of a second...
hmmmm....
must figure out how to get rid of 1000 pounds!

If you gotta consider it, your car aint fast enough.



lol j/k, just throw in a short shift kit, that will counterract any time you gain.

All that stuff only weighs 20 lbs? Or does it weigh 200 and you are .20 slower?

thats the same way I heard it.

of course if you dropped 1000lbs and had a 2200lb car... Id imagine youd be doing better than 13sec IMO. I think its an exponential gain type thing. time decreases faster as you get lighter. and increases slower as you get heavier(you think theres as big of a difference between 7000 and 8000 as there is for 2000 and 3000?)

Thats funny.. 1\10 of a second aint too bad considering i'll have a system finally..

Exactly... and being that most of us use our cars as daily drivers or at least street cars, good sound all the time is more important than a 10th quicker during a drag.

that's why you put the subs in backwards. That way, when they hit, they boost you.

My experience is that huge stereo boxes slow you down a lot... but you don't really notice it too much cruising on the street..

I used to have your typical "hatch full of speakers" and a ~$7K system a few years ago.. and I went auto-x'ing one year.. I was consistently finishing last and second to last through out the season until one day someone STOLE all my chit !!

Well, it was a blessing in disguise because the next auto-x I finished first.. and I was always in the top 3 for the rest of the season!

I've realized that I never really notice the car being slower after adding weight. But i always realize the car get faster when removing the weight.

So just add the system and never take it out and you'll be golden.
It's definitely worth being .1 slower in a quarter mile to have a banging system in a daily driver.
