I took the hub cap covers of my Neon and my 1/4 mile time improved by 2 seconds!!!!!!!!!!!!!

 

So now you are at 20 seconds. I dont think it was the hub caps, i think it was the tail wind.

 

20.4 seconds to be exact!

Now I know why all the ricer cars up here run their Civic DX's without hub cap covers (black stock rims). They must really fly!!!

Damn, maybe I should get some wheels with hub cap covers for my CLS. That why I could pop them off right before a race!

I'm also considering grinding down the outside of the wheels and drilling holes in them to save more weight. That way my wheels won't be balanced so when I "cruise" around I'll look like my car has hydraulics.

Actually rotational mass does effect the 1/4 mile time.... though I don't think a hub cap will chop 2 seconds..... I think more like 4 seconds.... just kidding.

The truth is for every 1 pound extra rotational mass, it's the same has having 5 pounds of static weight in the car. Also, generally, (on average) 100 lbs of static weight results in .1 seconds in the quarter mile. My Chrome GTX rims weighed about 25lbs extra apiece. So for the 2 front ones, that was 50 lbs. more rotational mass for me versus a GTP with stock rims. 5x50 is 250 lbs. or approximately .25 seconds in the 1/4. If you look at my times, I was on average .2 to .3 seconds slower than a normal GTP the exact same mods as me and identical 60' times, and similar weather settings.

 

lol, this reminds me of my friend back in high school who had a volkswagen sirocco (spelling?) he did a bunch of engine work (pistons, cam, intake, FI mod's)... but it still wasn't fast enough... so he took out the rear seats, and cleaned the trunk a bit... still not fast enough. So he took out the remaining interior including the carpeting, and everything that wasnt neccessary... so with one seat left, and a few guages he drove it around...

lol...

And then he put it all back together and bought a Mustang, and dropped a 460 in it

my point! there's no replacement for displacement! (Well accept those damb winkel engines!! heh 1.1L 250hp!! crazy)

Funny how people totaly ruin their cars to add a .1 of second.
of course mabye they dont think it's ruined...

 

Hmmmm...

1lb rotational = 5 pounds static

I think I'm going to use an angle grinder on my stock rims and grind about 10lbs off of each wheel....

10 x 4 x 5 = 200lbs static weight

.2s faster in the 1/4!!!

Of course if I hit a bump the rims'll probably snap!!!

 

good stuff to know ...my best 1/4 to date was with 23lb rims...i get my 16lb rims in on Tuesday...wow i just realized how old this thread is....anyways im hoping for good results!

7x4=28lbs off wheels.
28x5=140lbs of static weight! .1-.15 off!! tite.
