How to save weight...

[jsta6]

old page is up again, can be found here:
http://bellsouthpwp.net/s/h/shawnco/jsta6/weight/weight.htm

I am missing a few numbers.

Somebody chime-in and fill in the blanks:
=======================
Weight savings:
=======================
PLEASE BE CAREFUL WHEN PURCHASING AFTER MARKET EQUIPMENT. SOME PARTS MAY BE HEAVIER THEN OEM EQUIPMENT. For example, I bought some aftermarket OEM rotors that were 1lb heavier then my stock rotors. IF you are concerned about weight, ask the weight before you buy.
=======================
front bumper reinforcement (87 GN only):

steel = 64.5; aluminum = 45.8; savings = 18.7 lbs

Bumper Export Braces:
(export brace replaces inner bumpers support)
Chrome steel bumper with small steel export brace, no lights installed = 33.5 LBS

Front steel chrom bumper with only the export brace attachments, minus the center piece, no bumperettes, but does have the full length black strip = 26.5 LBS

rear bumper reinforcement (87 GN only):
steel = 69.5; aluminum = 48; savings = 21.5 lbs


rear brake drums:
steel = 10 lbs; aluminum = 5 lbs; total savings =10 lbs


front sway bar:
stock solid = 30 lbs; 1LE F-body hollow 20 lbs = ; savings = 10 lbs


front rotors:
stock 17.5 lbs = ; aftermarket @9.5 lbs (SSBC) = ; total savings = 17 lbs


front calipers:
stock = 6.75 lbs; aftermarket = @3.25 lbs (SSBC); total savings = 7 lbs


aluminum radiator support:
steel = 30; aluminum = 13; savings = 17lbs


door crash bars:
savings = 38 lbs


sound deadening material underneath and behind rear seat:
savings = 10 lbs


RJC pulley set:
stock = 10.5 lbs ; RJC = 3 lbs; savings = 7.5 lbs


Rims:
steel = 29 lbs; aluminum = @19 lbs (depends); total savings = 40 lbs
Centerline Auto Drags
15x10= 19lbs
15x8= 17lbs


Spare tire:
35 lbs


Jack:
15 lbs


Mini starter:
stock = 18.5 lbs; mini = @8.5 lbs (turbobuicks.com); savings = 10 lbs


Fiberglass hood:
stock = 55 lbs; fiberglass = 28 lbs; savings = 27 lbs


Fiberglass decklid:
stock = 60 lbs ; fiberglass = 23 lbs; savings = 37 lbs


a-arms
stock = 9.5lbs ea ; aftermarket tubular (UB Machine) = 4.5 lbs ea; total savings = 10 lbs

AC Compressor: 14 1/2 lbs
Core: 6 lbs
Lines: 3 1/2 lbs
Condenser Can: 1 lb
25 lbs total weight loss.

Stock IC with duttweiller neck: 15 1/2 lbs
Dequick V2 front mount, no pipes: 28 lbs

Conveters:
Precision 9.5 lock up (one quart fluid in it)= 37 lbs
Precision 9.5 non lock up (one quart fluid)= 29 lbs
Stock D5=41 pounds dry
9/11 convertor = 36 LBS DRY

[Kansas T]

Please specify the brand of the aftermarket parts. The global west a-arms are heavier that the stock ones and an LT1 starter is heavier than the LT4, but both will fit.

[jsta6]

What are SSBC rotors and calipers?

Stainless Steel Brake Corp:

[GNVYUS 1]

Here are a few more items to add to the list

AC Compressor: 14 1/2 lbs
Core: 6 lbs
Lines: 3 1/2 lbs
Condenser Can: 1 lb
25 lbs total weight loss.

Stock IC with duttweiller neck: 15 1/2 lbs
Dequick V2 front mount, no pipes: 28 lbs

Precision 9.5 lock up (one quart fluid in it): 37 lbs
Precision 9.5 non lock up (one quart fluid): 29 lbs

[turbofish38]

Gnvus do you know how much the D5 weighs??
My book says 41 pounds dry.

[turbofish38]

Also what about exhaust systems? Say stock compared to single 3" to dual 2.5" to dual 3" to crossflow 3" etc,etc.

[jsta6]

Thanks guys...I am also curious on the exhaust issue.

Somebody posted on this somewhere. I will try to find it.

List updated...

[EvilGN]

not sure if i am reading it right, but you have stock sway bar at 20 lbs, and hollow 1le bar at 20 lbs for a 10 lb savings???? did you mean stock sway to be 30 lbs?

otherwise good article

[Quick6'n'-K.C.]

here are some that i have written down

9/11 convertor 36 LBS DRY
PRECISION non lockup 32 LBS
stock D5 46 WITH FLUID

Chrome steel bumper with small steel export brace, no lights installed 33.5 LBS

Front steel chrom bumper with only the export brace attachments, minus the center piece, no bumperettes, but does have the full length black strip, 26.5 LBS

Aluminum core support 13.0 LBS
Steel core support 30 LBS

Front aluminum bumper support 12
rear alum bumper support 13
rear steel bumper with factory steel support 69.5
same rear with aluminum 48

Front bumper with steel support 64.5

Great thread, to bad I have spent a lot of money finding these part weights out!

Anyone with aluminum head/iron head weights?

Here's some I forgot about

Centerline Auto Drags
15x10= 19lbs
15x8= 17lbs

[GNVYUS 1]

I am finally noodling with the GN again and have some more weight updates.

Bowling Green 3" Down Pipe ( knuckle included ) = 16 1/2 lbs
3.5" THDP = 10 1/2 lbs
Stock GN Fan = 9 lbs
Ram Fans = 11 lbs
ATR SS 2.5" Y Pipe Exhaust = 15lbs

I will have the mild steel y pipe weight shortly along with what the dyno max mufflers weigh.

I updated the page about a week ago. I will update it again ASAp.

Just purchased a pair of Canadian T Type front bumper brackets. 3lbs each

These allow you to get rid of the 64.5lb front bumper brace.

6lbs vs 64.5lbs = 58.5lb reduction in front bumper weight. :rock:

Time to chop up that 69.5lb rear brace. :essen:

[Turbo Archie]

Use a "partner saw"

It's a chain saw but with a 14" abrasive cutting disc. It will cut through it like budder.

[GNVYUS 1]

All I have laying around here is a good ol sawsaw. Chopped up my talons bumper pretty nice but I will look into that saw.

Just took out the spare tire and hardware and my numbers are lower than the ones posted here.

Spare Tire = 28lbs
Jack/Bar etc = 8lbs

[GNVYUS 1]

Back again with some weight discrepancies.

The 36mm hollow front sway bar weighed in at 14 1/2 lbs, not 20lbs like the first post states.

That makes this the second item that was different from what was posted here. I see to many items that appear to be rounded off like the jack and spare at 15 and 35 along with the front 36mm sway bar at 20lbs.

Please people actually weigh this stuff, its not that hard. :joint: :yessir:

[RIBMASTERJOHN]

Stock 1987 radiator 26.5 LBS
Napa aluminum f-body radiator 10.0 LBS
Modine 88-92 Fbody part # 951

[jsta6]

old page back up again:
http://bellsouthpwp.net/s/h/shawnco/jsta6/weight/weight.htm

[Bryan C.]

Does the f-body radiator have an oil cooler?

It has a trans cooler, you will need an external oil cooler.

[GNVYUS 1]

16.5 lbs is pretty significant on just a rad, but I wonder what the lines and cooler would be due to the rad being oil coolerless? Not much I bet, sounds like a good 13lb drop after you get the oil cooler back in.

Glad the page is back up Jsta6 but we need to see whats up with these things

Stock front sway bar 30lbs ???
After weighing the Fbody hollow bar at 14.5, the site initially said 20lbs.

I weighed the stock spare and jack and they were not 35 and 15 lbs, it was 28 and 8lbs. I wonder if different GN's came with different spares etc? I doubt it but if someone gets some free time, just double check these items.

Should have some more weights soon as the motor is coming out again. I might ditch the ac/heater box and use BuickGn's delete plate, hoping for at least 20lbs after you ditch everything.

Thanks for your input. Yes, I am starting to see more and more discrepencies on weights. I think maybe we should start putting the persons screen name and date next to the weight they provide to us.

Speaking of which, I don't know if I can maintain the page since I have four small children. I wonder if Travis can create a page here that we can use? Or maybe over at www.gnttype.org?

If people want to have just one set of weights, I can delete/ edit the original posting, to reflect the changes, but I've just been waiting for the latest/ most correct info., before I took it upon myself to do that. Also, it looked like this thread was maturing well enough on it's own, so I was in part just *letting it ride*.

Go ahead Bruce. If you can maintain it that would be great. :rock:

[Bruce]

Things will be a little ugly, as I delete some of the posts, and whittle the thread down to just the most recent, and accurate info., in the end, it will just be *one posting*, with acknowledgments to those that contributed the various weights.

BTW, thanks to those that took the time to get the info.!.

[Quick6'n'-K.C.]

All the parts that i have posted here and on TB.COM i have weighed with a digital scale that measures within 1/2 LB.
I accidentally posted under my dads name RIBMASTERJOHN, he used my computer last and i weighed the radiator just last week?

These are the items that i weighed with the same scale, anyone wants to test their scale against mine feel free to.
I weighed the following and posted on both boards a long time ago.

Bumper reinforcement:
REAR:
steel 69.5 with bumperettes, aluminum with bumperettes 48 both having steel 5mph impact struts

Cut out 36"center section of aluminum reinforcement, no bumperettes,no impact bars, 28lbs
Leftover 36" cutout piece of aluminum reinforcement 8LBS
add bumperettes, total 10.0LBS

Bumper Export Braces:
(export brace replaces inner bumpers support)
Chrome steel bumper with small steel export brace, no lights installed = 33.5 LBS

Front steel chrome bumper with only the export brace attachments, minus the center piece, no bumperettes, but does have the full length black strip = 26.5 LBS

rear bumper reinforcement (87 GN only):
steel = 69.5; aluminum = 48; savings = 21.5 lbs


rear brake drums:
steel = 10 lbs; aluminum = 5 lbs; total savings =10 lbs

aluminum radiator support:
steel = 30; aluminum = 13; savings = 17lbs

Conveters:
Precision 9.5 7 disc lock up (one quart fluid in it)= 37 lbs
Precision 9.5 non lock up (one quart fluid)= 29 lbs
Stock D5=41 pounds dry

Stock 1987 radiator 26.5 LBS
Napa aluminum f-body radiator 10.0 LBS
Modine 88-92 Fbody part # 951

Now someone needs to weigh the oil cooler adapter and the hoses to get a true weight reduction when removing the stock GN radiator.
When i remove the factory radiators, i always install a tranny cooler after the new radiators tranny cooler.
correct the napa one does not have a oil cooler.
Also, the napa radiator does not take as much fluid as the stock radiator, if it takes 1 gallon less, then thats 7LBS right there ALSO!!!!!

BW

[Quick6'n'-K.C.]

Cut out 36"center section of aluminum reinforcement, no bumperettes,no impact bars, 28lbs
Leftover 36" cutout piece of aluminum reinforcement 8LBS
add bumperettes, total 10.0LBS

I need to look into the weight of the aluminum reinforcement when cut up, my math must be off, it shouldnt weigh 28lbs...


Bumper Export Braces:
(export brace replaces inner bumpers support)
Chrome steel bumper with small steel export brace, no lights installed = 33.5 LBS

Front steel chrome bumper with only the export brace attachments, minus the center piece, no bumperettes, but does have the full length black strip = 26.5 LBS


BW

What i should have said was i was able to get my complete front factory steel bumper down to 26.5 lbs not including the aluminum 5mph impact struts.
What i did was took the canadian export brace and cut the center section out of it, leaving just the pieces to attach the bumper to the 5mph impact bars.
I believe that weight included lights,front black bumper strip... deleted the bumperettes and alot of nuts and bolts.......
No wonder how i got that car to 3000#s :racer:

[Quick6'n'-K.C.]

Just purchased a pair of Canadian T Type front bumper brackets. 3lbs each

These allow you to get rid of the 64.5lb front bumper brace.

6lbs vs 64.5lbs = 58.5lb reduction in front bumper weight. :rock:

Time to chop up that 69.5lb rear brace. :essen:

That includes the bumper with that weight measurement.
So you dont really lose 58 lbs, its less than that
BW

[jsta6]

[GNVYUS 1]

Just got my hands on some aluminum front bumper supports,
1/2 lb each. :shock:
The steel ones must weigh 3 1/2 lbs each because the supposid weight savings is 6lbs when both are used.

I will come back with the bumper reinforcement weight and the bumper itself.

I am not ditching the heater box after all, so I am curious what that whole set up weighs?

And I asked 3 guys selling the stock front sway bars to weigh them and no ones gotten back to me. Oh well, I guess I will post back in the spring when I do that one. :dong:

[GNVYUS 1]

I just lost 48 1/2 lbs on saturday, how do I look?? :goldcup:

I got the F Body Rad ( 1990/350 ) Proselect ( Proliance/Modine ) and here were my #'s
Stock Rad = 26lbs
F Body = 10lbs
Stock Oil Cooler and SS Lines = 2lbs
F Body with no oil cooler = -18lbs.


I also ditched the front reinforcement brace and installed the Canadian bumper brackets
Stock Bumper with lights = 27lbs
Stock Reinforcement Brace with aluminum top piece = 27lbs
Stock Bumper Support = 4 1/2 lbs each
Aluminum Bumper Support = 1/2 lb each
Canadian Bumper Bracket = 3lbs each
The aluminum spacers on mounting plate = 1/2 each
I only used 1 spacer and dropped a 1lb right there.
Left over carrage bolts etc = 1/2 lb

By going with the Canadian Bumper Brackets and Aluminum Supports you lose -30 1/2lbs. :elefant:

By the way, I think my stock D5 converter 41# is not right.

And getting out the stock bumper support is tricky until notice the top bolt holding it onto the frame which can be found under the hood. :add_shit:

[DARRELLTHOMAS]

Remove the Fat Chicks from your car, its good for a couple hundred pounds :add_wegbr

[GNVYUS 1]

So far I have removed 309lbs, thats one large FAT CHICK :haha:

[GNVYUS 1]

Here is an easy one to get around 23lbs off.

[gdnf2et]

I personally weighed a steel radiator support and I got 22 pounds...I own two aluminum supports and they are at 11 - 12 pounds..There were no hood latches on any of them..An 11 pound difference has been listed on the G body boards before....Just trying to keep this accurate.....

[GNVYUS 1]

My part weight on the stock spare, jack and hardware should not be considered.

I just found out that my stuff was NOT STOCK. :confused:

I guess the prior owner decided to swap out with who knows what, but none of my stuff was like the stock pieces.

Would still like to get a reweigh on the stock tire, jack and hardware so that I can recalculate my weight loss.

[gdnf2et]

A GTA rim ( 16 x 8) is 17.5 pounds....The tirerack website will tell you the weight of each tire they sell..Just click SPECS when you select a brand and size... http://www.tirerack.com/tires/Spec.jsp?make=BFGoodrich&model=g-Force+T%2FA+Drag+Radial+2

[GNVYUS 1]

Just got done weighing the ac/heater box delete mod.

*Edited due to forgetting about the heater hoses, valve and clamps etc at 2 1/2lbs*

-34 1/2lbs ( includes air duct work in the car and heater hoses/clamps)

+1 1/2 lbs ( BuickGN delete plate )

You drop 33 lbs by going this route.

AC Core alone was 5lbs
Blower Motor and tiny chunk of the box was 5lbs
Air Duct work inside the car was 2 3/4 lbs

And for those who looking for a heads up on this delete, you will need a 7mm for pretty much everything and a 1/4 for the top section of the ac/heater box. The big bolts for the plate are 10mm and I broke the box up so it was not that hard to get at the lower 2 bolts near the passenger fender.

There are two vacuum lines you need to take off for the air duct work under the drivers side of the dash. Then move over to the passenger side and you need to drop the lower part of the air duct with a 7mm to get at the upper middle 7mm bolt that holds the air duct to the radio/counsel. After you loosen those two bolts and the vacuum lines you can slip out the air duct.

[GNVYUS 1]

Just got the Odyssey 680T dry cell battery.

Pronto 690cc = 30 1/2lbs
Odyssey 680T = 14 1/2lbs ( with auto terminals )

I dropped 16lbs and the cold cranking amps were very similar.
Doesn't matter to me though as I no longer have any heat!!:SHOCKED:

Also ditched the EGR due to the VPE intake being welded closed at the egr tower.

EGR = 7/8ths of a lb
Buick GN Egr plate = 1/8th
Drop 3/4 of a lb. Ya. :sleep:

Rear bumper support brackets and hacking of the steel reinforcement are next on the list. Hope to see around 30lbs total.

[GNVYUS 1]

Ditched the fuel vapor canister. = 2lbs

All you need is a Purolator fuel filter from Pep Boy etc and put it at the end of the line from the tank and all is good.

[GNVYUS 1]

Finally got around to trimming the rear bumper brace and swapping the supports.

Stock bumper supports = 4lbs each
Aluminum bumper supports = 1lb each
Save 6lbs

FYI, Stock bumper without the bracing or rubber strip = 24 1/2 lbs

I cut the stock brace up into two mounting pieces. I cut each one after the 4th bolt hole on top and left one bolt hole on the bottom. This will allow you to attach the stock steel bumper onto the aluminum supports.

Left over cut up center section steel brace = -23 1/4 lbs

FYI, Steel bumper mounting pieces I cut from the factory brace = 5 1/4 lbs each.

The left over bolts were a hair over 1/2 lb.

You pretty much drop off 30lbs by sawsawing the factory bracing and going to the aluminum supports. :sprite10:

[jsta6]

how do the fiberglass bumpers work?

Is it the "skin" that goes over the support? or is it a one peice design?

I have never seen one in person. Can someone who has one that hasn't been installed yet take pictures of the back of one?

[Quick6'n'-K.C.]

Man this thread needs to make it to the top.

I never got a email saying ya'll posted, which sucks cause i would have liked to compare notes at the time.

Anyway, now this thread is back to the top and i can go back to it this week and pick apart how i want to shed 200lbs safely off my car.
Already ditched the stock swaybar with end links and ditched the factory starter for the LT1 starter.
Whooo hooo
BW

[GNVYUS 1]

Weigh the stock sway bar!!!

I have yet to swap it out with the F body.

[Quick6'n'-K.C.]

Scale battery is getting kinda low from weighing all these parts.

24.0 with factory end links, bushings, and 4 bolts that hold the bushings to the frame.
Like i said, battery is getting low. But i measured it 10 times and got 24 the last 7 times
BW

[GNVYUS 1]

Oh ya, here are some part weights to really put you closer to the new Z06 in weight.

Cruise Control ( not with the hose leading back to the firewall ?? ) = 2lbs

Emissions Dome ( under drivers fender ) and lines ( includes the lines off the EGR solenoid ) = 1lb

:haha:

[Quick6'n'-K.C.]

Have you taken your car down to the scale house lately?
BW

[GNVYUS 1]

Not yet, new motor has not even started yet so the trip to the local waste management plant has been postponed.

Goal is a 3150 on a 1/2 tank, which would be great for a T Top, no fiber doors or aluminum block/head car.

[Quick6'n'-K.C.]

3150 would be very very sweet. Is that with driver, i assume so?

I need to take all this info and apply it to my white car in my sig, but i dunno.
It would only go faster.
BW:arco:

[GNVYUS 1]

If I can get that with driver I would be impressed. I weigh 190 and I would think that the T Tops are about 40lbs more than the solid roof GN's. Anyone??

Add on the FMIC, extra bracing, Preluber, PTE oil relocator, Alky kit and the larger tires I probably added 60lbs right there to make up for.

I think when I got this GN it weighed around 3560 without me in it.

I still have to do an aluminum or carbon driveshaft, star flanged Moser axles and tubular upper and lower front control arms. There is maybe a realistic 40lbs left for me to ditch and I am done unless I go aluminum heads.

[rg496]

Do you guys have a source for the lightweight Canadian stuff?

Basically I'm looking to replace the rear bumper crash absorbers -and- get brackets that repace the need for the inner bumper support while still allowing the outer bumper to be attached.

:beer:

Thanks

I think gbodyparts.com sells them.

[rg496]

Perfect. They have the aluminum bumper struts. Now all I need is a source for a bracket to replace the aluminum inner bumper. I could just cut it to two small pieces but I'd rather not destroy it if I didn't have to.

Thanks JSTA6!!

[hissin Buick]

very interesting gonna have to bookmark this one!

[GNVYUS 1]

The front support braces can be found on ebay for around $50 ( last I checked ) they came on Canadian GN's.

I made the rears out of the old steel bracing, mine weighed 5 1/4 lbs each.

You could just chop up the aluminum front and rear support brace and make your own Canadian style brackets, but that would cost more. The steel Canadian fronts were 3lbs each and the steel rear was 5 1/4lb each so there might be 8-10lbs right there if you use the aluminum brace chopped.

Might play that card to pull off my sub Z06 weight goal. :scared1:

[ws6formula50]

anyone got the diff between iron and aluminum heads? I didnt see it in the thread, maybe I missed it

[GNVYUS 1]

I DHL'd a box of bare heads and it was either 84 or 86lbs ( can't find receipt ). The box could not be more than a lb so around 85lbs for both heads.

[gdnf2et]

I just installed the Champion bracket that KEEPS the power steering pump..The factory accessory bracket with all the bolts, nuts and alternator brackets was 9.13 pounds...The Champion bracket and all parts included is 3.2 pounds..I had done away with my AC long ago and had a factory AC delete pulley also..I weighed it by itself and got 1.3 pounds....So after all that, my car is 7.14 pounds lighter and have one less pulley..9.13 + 1.3 = 11.0....11.0 - 3.2 = 7.14.....

[johnplogii]

For what it's worth, I just cut the door crash bars out of my car & they weighed 13.6 lbs each for about 27 lbs savings not 38.

[gdnf2et]

I just bought a set of M&H p275/55R16 drag radials..They weigh 26.2 pds each....

[Scott4DMny]

What about converting power windows/locks to manual??? Or did I just miss it?

[Quick6'n'-K.C.]

I have heard that its not really that much difference...

Man this thread is valuable! :D

BW

[Sweet6]

I bought the SSBC rotors and they were not any lighter than the stock ones I took off. Granted the stock ones were cut twice and had 80,000 miles on them. So hard to say if the weight savings are as advertised. I needed rotors anyway and these are nice. So I am not mad.

[GNVYUS 1]

Powermaster ( dry as possible ) = 12 1/2 lbs

Vacuum Booster and Master from NA 3.8L Regal ( totally dry ) = 10 1/2 lbs

You drop 2lbs by ditching the Weakmaster.
( I didn't do the swap for the 2lbs by the way :add_wegbr )

[gncollectables]

great info! handy thread! thanks for sharing!

[30+PSI]

Has anyone figured Alum. Heads to stock Irons? :nixweiss:

[GNVYUS 1]

Weighed the T Top GN today with a half a tank = 3300lbs ( just car ):crybaby:

My goal was 3150 like the Z06, so now getting to 3200 is my goal.

How the hell am I going to drop off another 100lbs???:thinking:

Aluminum block and head #'s would be interesting to hear about, anyone??

[Scott Atk]

Does the rear deck lid actually weigh more than the hood? Doesn't seem possible.
Also, are the weights advertised for the pin-on hood and decklid or the latch/hinge style?

Another one I would like to know is 2004R vs T400.

[jsta6]

Weighed the T Top GN today with a half a tank = 3300lbs ( just car ):crybaby:
...

Damn...how did you do that...

I guess it's low for a T Top GN but it's still a tad heavy IMO considering how much weight I have taken out.

I have a huge list if anyone is interested in my personal weight reduction items, just email me at gnvyus1@hotmail.com.

I am down a total of 415lbs but things like the FMIC, Preluber, Bigger Tires, Alky Kit, Turbo Saver etc add weight so it's not as low as I would like.

do tell...

Does the rear deck lid actually weigh more than the hood? Doesn't seem possible.
Also, are the weights advertised for the pin-on hood and decklid or the latch/hinge style?

Another one I would like to know is 2004R vs T400.

About a year ago we did weigh a used DRY stock GN BRF transmission and a D5 convertor that had been drained against....

A Built BOP turbo 400 with a aluminum valve body with the hipster trans brake and a switch pitch convertor.

From what ive been told, the 400 is alot heavier than the 2004r, but what we found out was the 400 was only 5 pounds heavier.
The smaller turbo 400 convertor and the aluminum valve body makes a big difference i guess?

Hind site, i should have wrote down the weights and not gone with the switch pitch setup, it should have worked, but the convertor puked really soon.

We used Paul Ferrys conversion kit to bolt the 400 to the stock cross member.

What about the aluminum (T-Type) bumper braces vs the steel (GN) ones ? or even cutting off the whole middle sections on either 1 ? Anybody done this & weighted them ?

Go back and read the thread. I did this on my sage green car and i believe the numbers are here.

Here is my massive list of part weights, after reading it and then calculating the cost of the mods you can see why weighing a touch under 3300lbs was a bit disappointing to me. Most of the mods were done to upgrade my GN's performance in some way but later it turned into an obsession. :icon16:

I left the parts that add weight along with parts I know about at the bottom.

Here is a link for removing the crash bars in the doors:

http://www.turbobuick.com/forums/showthread.php?t=39017&referrerid=3922

I would like to take mine out and replace them with a lighter and stronger material.

I have an aluminum hood on my 85 cutlass. It weighs a lot less than a fiberglass hood. I wonder why TA performance hasn't stepped up and started making aluminum body parts yet... :rockwoot:

[GNVYUS 1]

Even better would be carbon fiber doors with carbon fiber crash beams.

I am pretty sure both the fiberglass doors and the carbon doors I saw somewhere did not have the crash beams. I am sure they assume the car is a track car but carbon doors with carbon beams would probably make a safe street car door.

Switched spindles today on the 83 Monte..The stock is 12.6 each, the Bell tech is 14.9 each......

Found this on another board from a member.


The aluminum GN1 head with shaft mounted T&D roller rocker arms installed weighs 17 lbs. ea.

The stock iron head with shaft mounted stock rocker arms installed weighs 33 lbs. ea.

You lose 32lbs

I shipped two bare stock heads with the intake at 86lbs to give you an idea of what the stock intake might weigh.
( probably 4lbs of shipping weight )

Sureflow 150psi pump weighs a tad under 4lbs.
I've got two of these now. :crying: :icon16:

3.5" Aluminum Driveshaft and Stock Driveshaft weights coming soon.

[GNVYUS 1]

Got my updated tranny back and here are those Driveshaft weights.

Stocker = 16.5lbs
3.5" Aluminum = 14.25lbs
_________________________
Loss of 2.25lbs ( rotating )

The 3.5" aluminum shaft was from Inland Empire. It had a beefier trans yoke and 1350 u joint up front with just a stock style rear u joint.

Both driveshafts were trans yoke to rear u joint.

Not as much of a loss as I'd have thought but the yoke and shaft are definitely bigger on the Inland.

Did the front sway bar swap today and it's not even close to whoever had 30lbs. Not even sure it was worth the $$ and time to swap it out.

Bars were bare, no end links etc.

Stock 32mm Swaybar = 21.5lbs
F Body 36mm Swaybar = 14.5lbs

Yeah, I hear you. I went to ship one and I realized it wasn't 30lbs??? Maybe the made different ones using different alloys? :confused:

Lose weight

[GNVYUS 1]

Hard to lose 421lbs when you're 6'2 and 200lbs but I guess there is 15lbs in here somewhere to reach my ideal UFC weight class. At least it'd be more than the measly 7.5lbs I just lost Tuesday.

BTW, the frame notch kit box weighted 60lbs and it's pretty much one cardboard box with no padding inside. :frown:
Guess I'm adding about 70lbs when the notch and 325/50's go on. :crybaby:

[GNVYUS 1]

Qa1 Rear Adjustable Shocks = 3.5lbs each

CAS V2 FMIC with 2 hoses and 4 T Bolt Clamps = 30lbs dead on.

3" Intercooler pipes with a Blitz Blow off ( no hoses or clamps ) = 5lbs

[GNVYUS 1]

PTE Turbo Saver and braided line, no oil filter = 5lbs dead on

[GNVYUS 1]

PTC 9.5" N/L torque converter dry = 28lbs, 4 ounces.

I'll lose another 6lbs when I swap out the Precision 5 disc for the PTC. Getting close to the Vette Convertible weight of 3221lbs and finally can say I'm lighter than the ZR1 at 3333lbs .
