Oh wow! That looks basic as all hell! Pretty lightweight though, I bet!

 

that setup is 74-86 pounds lighter lol

 

Pinto rack is a manuel rack & pinion steering system. Crappy if you want to actually handle good lol.. a lightweight, quick ratio power rack & pinion would be such a good mod IMO because it takes the strain off the frame rail and it's lightweight and has so much better precision than a steering box. Trust me I have a Lee Built 670 box and it's decent for handling but in terms of center precision it just doesn't compare to rack & pinion.

 

Actually, They are great for handling.... at 60mph+ lolol. The drag car at my highschool has a manual rack, and at speed you can steer with your pinky lmao

 

Must be a crappy ratio or have very little caster if you can pinky steer it. A stock IROC steering box has 12.7:1 steering ratio (2.25 turns to lock). I don't know if any racks exist where you can achieve the same turn to lock ratio (that are power, AND are lightweight and durable enough for racing)

 

no... it's just easier to turn at high speeds? the ratio is at least 20:1

 

20:1 is a terrible and slow ratio for handling. To turn a corner you'll have to turn the wheel so much.. I like the quick ratio of the IROC boxes. Makes low speed turns require a bit more effort but worth it big time when it comes to handling IMO.

 

..... well it handles fine. More than fine. the pinky comment referred to steering response.

 

pinto rack is more along the lines of a 16:1 ratio. my car with skinnys actually steered great for a weekend cruiser until i put a spool in, now its both hands on the wheel. i could drive it in parking lots one had before no issue. parallel parking pretty tough, but not much of that around here.

its been forever, but all my power steering setup, box and all of steering components were around 50#. a pinto rack is only 12# not to mention i made a new steering shaft that is lighter as well.

all in what you are doing with your car.

 

Very true! For drag a lighter weight manual rack is 100% the best option for all out drag car. I just raced last night at a track called "iCar" in Montreal (it's on an old airport tarmac) and I drove a brand new mustang (completely modified, stripped, roll caged, open exhaust, etc) and the handling feel and road feel was fantastic. They are power rack & pinion.

 

the manual box on summit was 20:1 thats where I got my assumption from

 

Just posting up some weights on items as I was cleaning my garage.
Stock steel crash bar #25lbs
Stock aluminum crash bar #15lbs
Stock steel drive shaft #14lbs
Stock aluminum drive shaft #11lbs

 

Crash Bars....I'm assuming both are the Front ones you listed? I don't know of any rear aluminum one so.......

 

so the complete a/c system weighs what?

 

If i remember its like 35-40.

makes the engine bay soooo much cleaner though.


before



after

 

the 86's have computers? or no. mine is carburated.

 

86 tpi, or tbi would.

 

kk thnx

 

mine is around 2800 pounds give or take stock... although its not got WS6 suspension :P although it may also be with an empty tank, thats what my registration says it weighs

 

have you had it on a scale? i highly doubt it weight what the title says. those are not "real world" numbers...

 

Yea mine says it's 3000 stock but it's actually somewhere near 3600, but they just get that from the provincial database of cars, which in Quebec is pretty far off from what it is. My car now weighs in at 3350 or so on a truck scale.

 

My driver side 3rdgen leather ultima seat weighs 60lbs and the pass seat weighs 40lbs. both seats with the stock 3rdgen tracks

 

well its a base model so its lighter than a trans am would be stock.

 

my car weighs right at 3020lbs without me in the car, and it's pretty stripped down. but since my weigh in of 2810, i've added a th400, a 9", and a roll bar, which added up pretty quickly. right now, it's 3320 going down the track. hoping to get that closer to about 3250 before the end of the year, but i'm going to be adding more weight into the car soon too (more bars, more stuff under hood, etc.)

 

I just had my car weighed at a scrap metal company, was 3300 with me in the car, i weigh around 150 so without me right around 3150. I thought the weight was pretty good for still having the rear seats.

 

cant wait to get my BMR k member amd A arms in there. Also the A/C delete. I have t-tops for a reason :P

 

it´s maybe have been up before, but what does the entire steering parts weigh (steering gear box ect) except the servo pump

 

power steering setup w/pump,belt,gearbox,lines, brkts and bolt 46lbs

 

that was a little weight. do you have any idea what i power steering rack can weigh?

 

No & I don't know of any pre-made to fit stock setups either Just the things like the aftermarket K-member designed to use R&P.

 

Tubular a-arms and k-member with a power R&P setup would reduce weight significantly, but R&P is a complete custom job, people have done it but there's is no bolt in setup out there, yet..

 

Where did you get THAT?

 

Interesting read up on automobile handling. It goes in depth about suspensions and how weight affects different aspects of handling (sprung, unsprung, rotaional, etc.): http://medlem.spray.se/bmw02hemsida/...Suspension.htm

 

I rule..

 

For anyone interested on seeing unsprung weight in action, I found a video on youtube of a guy filming his rear-end in motion while driving.. (Mounted the cam underneath the car). You can see the rear diff in motion going over bumps and turns, but the interesting part is seeing the UNSPRUNG weight moving in action.

 

Sorry to double post but I found an article on hoses and how racing hoses can reduce weight: http://www.majon.com/articles/automo...hose_1372.html

Makes sense if you replace all the hoses/fuel lines on the car maybe? Good for a few pounds maybe? I guess this could be done if you've literally reduced every ounce of weight possible and have nothing left?

 

What about the deck lid there is a lot of metal on that thing. Anyone ever tried to "gut" it? I am 160 lbs over for the class I want to race in and I need to find some weight.

 

The rear hatch w/o any wing or spoiler is 90lbs. And the majority of that is the glass, not the metal decklid. Cutting out even the entire inner structure isn't gonna save much weight. The glass is the heaviest part.

 

Isnt it bad to take weight off thr rear? It'll throw the balance off. Most of the "bad" weight is on the front.

 

-revives thread- MWAHAHAHAHA! how much does a 350 weigh again? I wanna do an LS3 swap and thats a 400 pound motor with the bells and whistles (not sure if thats oil in or not, thats the shipping weight and I'm damn sure they come with oil in them O.O )

 

swapping an ls into these cars you cut around 100 pounds

 

2970lbs without my 200lb butt

 

Does all this weight reduction lead to any significant mpg gains? Thinking of doing this as well because I just use a daily driver.

 

yes, any time you make it easier for the engine to move the car, it becomes more efficient as a whole system. i don't know if there is a certain constant like there is in racing (reduce 100 lbs, drop approximately .1 second from 1/4 mile time) or anything, but taking weight out can't hurt mileage.

be careful how you do it though, don't sacrifice on road safety for possible increases in mileage.

 

Not only might it increase gas mileage, if done properly and safely as mw66nova said, it could actually make the car safer (less braking distance, better more evenly distributed handling, potentially lower center of gravity makes it less likely to roll over, etc.) .. It also reduces wear and tear on things like drivetrain, suspension, tires, brakes, etc. I've reduced estimated 250lbs from my car and it looks like it was never touched (minus the fiberglass hood). All the small, albeit expensive, lightweight parts add up too!

 

is there a stock weight thread?

 

I got a '91 GTA with cloth power lumbar seats. Anyone have a weight on them?

 

i havent wegihed one in years. i think my camaro power(no lumbar) was either 53 or 33, but i know it was heavy.

 

1991 TPI dual snorkel cold air intake 3.1L stock v6


MAF connected and wired in.



Next mod aluminum driveshaft hopefully I can find one at my local junkyard I'm not going to spend 80$ 100$ for a new one wish me luck. Did 92 91 90 z28s have Al ? Or will I have to get one out of 2001 2002 2003 2004 4th gen? What's years can I use does anyone know?


(If anyone wants the dual snorkel cold air I have one for sale)

 

I work at a place that does a lot of allum fab stuff. I seen we can break sheets of alum and weld it too. Im thinking of converting my front latch support to allum, and any other bracket type steel on my front end. But doesn't allum and steel corrode together?
