I heard that for every 100lbs you cut from your car has the same effect of adding 10hp to your engine.

Any thoughts?

 

for what car? i call BS

 

97 max. what would you say? how many HP for 100lbs.

 

Put a spoiler and loud muffler on it that gets you at least 50HP.
It's not rocket science. You loose weight, your horsepower to weight ratio goes up... it's like 7th grade math you can figure it out. By the way.. it's a lot easier to add 10HP than it is to loose 100 lbs.
and it turns out thats dropping 100 lbs gives you the same HP/weight ratio that adding 6.5HP would give.

 

You could drop a hundred pound off the maxima pretty easy.

Light Weight wheels (save about 30 lbs)
CF hood (save about 20-25 lbs)
Light Weight Battery (save about 15 lbs)

Thats 70lbs right there.

 

I think it goes for every 100 pounds you take off your car its about a tenth of a second off your 1/4 mile time. idk if there is any truth behind this, but thats just what i've heard

 

but once you get that stuff done (interior etc) your stuck unless you start removing windows and replacing with lexan or getting lightwight body panels.... Lets just say there's a limit to how much weight you can lose, and the closer to the limit the more money you spend on it. Horsepower is the same, but the limit is much higher.

 

and on our cars 100lbs is pretty much = to .1 second... some time reading in the advanced performance forums helps

 

I think it goes without saying that 200 bucks for a Y-pipe will give more benefits for 1/10 of the price. Unless you don't care about AC, Music etc...
Weight loss is the last step to making car quicker.

 

Agreed. When youve spent a year's worth of pay to make your car fast, and STILL cant break 12, then its time to start cuttin

 

depending on what it is. there are a few quick things like pull the spare, CF hood, and the things Dubbya said. but smaller things like composite parts and such are usually to fine tune everything.

 

yup, thats what i've been told, but then i'm thinking, i think i'd rather keep my ac n heat rather than just to be a few tenths of a second faster. I got my bike for that...-= )

 

I tested this out just now

my friend has a 2001 audi s4 2.7 twin turbo automatic

he is 260 pounds

we ran the car on a g timer

with ryan drivin he ran a 14.72 (stock)

I ran a 14.56 ( I'm 100 pounds 160 pounds less than ryan)

next ryan ran a 14.50 with the spair tire out the floor mats our the wood trunk line and the trunk floor mat also we drained the wiper fluid and took the air filter out and we took out the 6 disc changer tray

and then I drove the car with everything removed as listed above and I have a 14.30

all of this was on a 1/4 tank of gas or less

 

like what the 3d man said... as you lose weight your power:weight ratio decreases.

Power:Weight = The reason why hondas can be so quick with such little modifications. They thank the laws of physics everytime they get to a light.

Thats why motorcycles fly like F-18's . They have in the neighborhood of 180 bhp and the bike itself weighs only about 450lbs. If you put a 250lb guy on the bike that makes the Power:Weight ratio less than 3.5:1

In comparison, the stock 4th Gen's Power:Weight is just about 15:1

Hope that answers your question

I like to ramble, 'case ya hadn't noticed

 

Im sorry I dont mean to hijack this thread but I would also like to know if packing your intercooler with ice before you run the 1/4 mile will help you et time

 

start a new thread, amimaxima

 

good idea i'll start it in the supercharged/turbo section

 

I always prefer to lose the weight first. More power only improves acceleration and top speed. Losing weight improves acceleration, agility and braking. It'll also improve fuel mileage since your not wasting as much energy from lugging around extra mass. I'd start with reducing weight on any rotating parts (wheels, pulleys, flywheel,...) since you get more benfit out of it than reducing weight on nonrotating parts.

 

if anything 100lbs takes off about (and i say that very loosely) .1 on the quarter mile

 

If your building a track car, strip it out and add power.

If your car is your daily driver, then add bolt on till your happy or sacrifice what you can, A/c etc.

 

y sacrifice ac... for weight?..... it doesnt take anything off the motor it runs with the clutch disengaged when not using it

 

Then all you need is a VQ35DE... best weight reduction of all.

I hate to nitpick, but all your ratios are backwards. the bike's power:weight would be 1:3.5. Decreasing weight increases your power:weight.

 

oh god maxima tuner math

 

Already did it. 35lbs of weight reduction.

 

Dropping all the AC components saves a lot of weight. Think about everything that is involved.

 

I know youre referring to FERRARI guy, but Ive thought a looooooot about it

 

If mine wasnt a daily driver the ac would have been gone long ago.

 

Something to consider:
the popular power mods typically have their greatest effect relatively high in the power band. Theoretically, weight reduction would result in a uniform performance increase across the power band.
Practically, however, as has been stated above, it is a heck of a lot easier to bolt something on than to drop enough weight. (Especially on a daily driver.)

 

I think I could handle it - just not 100% sure if I want to yet.

If you had a beater would you take off PS pump/belt too?

 

Duno. I would have to try it and see how much of a PITA it would be. My friends 86 Corolla doesnt have p/s and that thing is a heck of a lot lighter than a Maxima.

 

I dont see why you people think that. Weight reduction is easy to a certain point. I think the weight reductions I listed above are harder to acheive than say headers.

 

.. either you're a female.. or...

 

or Ken......but seriously I think he ment 100lbs lighter.

 

... read it again...

 

well well then. i stand corrected. talk about a lightweight.

 

yes im 100 pounds

 

OK, what is a good lightweight batter cost, where do you get one?

My battery is weak now and might as well lop another 15lbs or so off the car.

 

Oddesy is the best one that I have found.

http://www.motorcyclebatteriesusa.co...sp?battery=159

A few maximas use that one. I plan on getting one when the Never Start I have finally pisses me off.

 

i can curl you with one arm

 

i know braille makes some lightweight batteries too.
