1 tuff z Posted September 3, 2011 Share Posted September 3, 2011 (edited) Mike, my z is within 50 lbs of yours [i'm 180 lbs]. Ls1, t56, alum rad, 6 pt autopower cage, stock fuel tank with atl black box, factory glass all around, corbeau seats, sound deadening [factory] there, q45 diff, 17" wheels and disc brakes. f-r distribution is 49-51 and cross weights are within a percent of each other. So, what are you and I doing wrong with our z's?! They seem to be about 200-300 lbs heavier than the others here.

mr jdm Posted September 3, 2011 Share Posted September 3, 2011 I'm gonna weigh my car on Tuesday. I really think I will be in the 2300 lb range. There's no ac, no heat, fully gutted interior, engine and chasis wiring tossed in garbage, car has bare minimum in engine harness and body, fuel cell, aluminum dash, fiberglass hood, no steel bumpers, and asr20 with side exit exhaust.

Mikelly Posted September 3, 2011 Share Posted September 3, 2011 (edited) David, I don't know man... I'm just a little confused. My seats combined weight 36 pounds. My dash and gauges weigh maybe 15 pounds. My doors don't weigh more than 12 pounds each. My hood is carbon fiber and weighs nothing. No rear bumper or bumper hardware, the front bumper beind an MSA Type 3 airdam/bumper that weighs maybe 15 pounds. Areas I know I can whittle down, tires/wheels are heavy and we have a solution in the works for that. The battery is heavy, so maybe a Braille unit could help... What else??? I know my cage is pretty substantial, but it's still only 1.5 inch SCCA legal tubing. The fuel cell is lighter than the stock fuel tank. MrJDM, You might make that weight, but you likely may not. I got the numbers Thursday night and wanted to puke. I was expecting 2300-2500 pounds, but NOT 2700 pounds... No way in hell... Well... Here I am... 2700 pounds. Here's what I know... I have the means, and if need be, I'll gutt the cage and start over on the car. This car WILL lose the weight... I've lost 30 pounds in three months, and I'll lose another 30 over the fall/winter... The car has got to shed pounds if I'm going to enter it in anything worth doing with it. Mike Edited September 3, 2011 by Mikelly Quote Link to comment Share on other sites More sharing options...
Mikelly Posted September 4, 2011 Share Posted September 4, 2011 (edited) By the way, this is a very handy little corner weight calculator... http://opuscorvair.com/cornerweightcalculator.html My cross corner weights are pretty decent at 48.5%, and the front to rear is really good ... 48.2 front/51.8! Even if she is a heavy pig!!! Mike Edited September 4, 2011 by Mikelly Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted September 4, 2011 Share Posted September 4, 2011 (edited) Cooll link Mike-here are my results. · Weight [1/2 tank gas] 2769 · Total wt 2944; front:1451, rear:1493 [including 175# driver] · Corner wt w/175# driver; 754 LF, 747 LR, 703 RF, 740 RR · f/r weight distribution 49.49 / 50.509 · cross weights 50.7% lf / rr, 49.3 rf / lr With a cross weight of >48.5%, you have what is considered to be a TIGHT race car. Just added power windows so it may have gained a bit of weight, perhaps once the long tubes are completed and installed it'll offset that gain or I may have to install a little cam...

jhm Posted September 6, 2011 Share Posted September 6, 2011 Gents- My 260 (late '74 model) seems to be a little on the porky side, too (2810 lbs w/o me)....but it doesn't surprise me, considering the way she's currently fitted out (weekday DD, weekend play-racer): - iron-head SBC w/ TH350, mini-starter, aluminum water pump, aluminum intake, block hugger headers - Autopower roll bar - full interior, w/ Honda Prelude seats (fairly lightweight) - street wheels & tires - steel flares - half-tank gas - bumpers removed (saved 90 lbs!) I drop 70 lbs immediately when putting on the race wheels. r/John Quote Link to comment Share on other sites More sharing options...

wesmc Posted August 13, 2013 Share Posted August 13, 2013 Mine is 2,300 without me in it. It's an inter cooled L28ET swap in a stripped interior (with sheet metal dash instead of factory one) 1973 Z. My 72 with a 2.8 NA, most interior removed, roll bar with backstays, all glass still in, gutted dash just scaled at 2254. Quote Link to comment Share on other sites More sharing options...
wesmc Posted August 13, 2013 Share Posted August 13, 2013 Last time I had mine on scales it was about 1983 lbs without driver, and with a couple gallons of gas, it had the full dash, but no interior plastics, all sound deadening removed, the seats replaced with Kirky aluminum shells, no side glass, rear glass replaced with plexy, and no lights. It has no lights now, just brackets to hold some switches and gauges, the harness has been removed, and I ground off many of the now useless brackets for holding stock interior stuff. I need to get it on the scales again eventually to corner balance it. This is where I have to get....vintage rules allow me 1950lbs so I have 300 to go. I may have to PM you for some help moving into your neighborhood. Quote Link to comment Share on other sites More sharing options...
Phantom Posted August 20, 2013 Share Posted August 20, 2013 I've kept track of the weight of my '77 280Z. In stock form with the L28, 5-spd, R200, MSA type 1 ground effects kit, and 3/4 tank of gas it weighed 2,800 lbs - evenly split front and rear. Same set-up after the LS1/T56 conversion it weighed 2830 lbs - 1,400 on the nose and 1,430 on the tail. After doing the full interior - dynamite, leather, house carpet, front and rear sway bars, 4-pt roll bar and a 7 speaker 500 watt sound system the car porked up to an even 3,000 lbs - 1,440 on the nose and 1,560 on the tail. These weights were all taken on the same certified truck scale. During the conversion I had corner weights taken and they totalled up to the same front and rear as the truck scale.

fhptom Posted February 20, 2014 Share Posted February 20, 2014 Just picked up a 11/70 240 bare chassis - has front suspension/steering rack/column/wheel & rear suspension/r180 diff - 14" steel wheels with tires - nothing else. No doors, hood, hatch, interior or any lights or wiring. 1085 lbs. I am thinking of transferring everything from my 260 race car to this chassis to trim down my bulky 2350 lbs.

wesmc Posted February 20, 2014 Share Posted February 20, 2014 Wow..1085 naked and we need to be at 1950 race weight to take advantage of the '72 SCCA GCR. It is looking tough to do. Quote Link to comment Share on other sites More sharing options...
