911 Vehicle Weight

[LongRanger]

. . . like to oblige if I can find a scale . . .

Uh-uh, Bryce --- I ain't goin' for it . . .

I've seen you dig into wiring diagrams, option codes, all the sundry minutiae of the '69s --- not to mention your handy-dandy little trick o' using google to narrow searches on our site . . . . so I know you've got the tools to figure out where/how/what to do to get a weight on your car, there, Bucko . . .

. . . don't even . . .



Besides . . . Raj and Luke are selling their cars . . . so they're kinda Done with the Whole Deal

. . . which leaves you . . .


. . . and maybe Spencer (///msw3) . . .


C'mon

[Bert]

I'd love to hear from some o' the '69 Guys on this board --- like Bryce, Raj, Luke, et al . . . read what figures they have. '69s are supposed to be the lightest of the 'S's

Also, anybody w/ a Karmann-built coupe --- especially a 'T'? Allegedly the lightest shell of all

Also --- more/any Targas

Hi Rick,

My 1970 911T was the second lightest car on page 1 of this thread at 2376 lbs. It is also a Karmann built coupe. I haven't made many light weight mods to the car. The interior still has the heavy sofa seats, stock carpeting and full door pockets. No fiberglass or aluminum anywhere. Tool kit included. Steel trailing arms and 18 mm sway bars (F/R), plus deep 6 Fuchs. Stock 2.2 T engine with Webers.

My car has not gone on a radical diet, but it was the second lightest car at the weigh in. It looks like the Karmann cars were built lighter.


2376 . . . . . 1970 911T, 5/8 tank gas, Spare tire in place. No radio, vent blower motor, rear seats. Small Lightweight Odyssey battery.

Hey, Bert!

Hmm

Interesting --- especially compared w/ the figures for the other two '70 T coupes from your group . . .

2483.5 (1126 kg) . . . . 1970 911T, 3/4 tank gas, Spare tire in place
2524 (1145 kg) . . . . . 1970 911T, 1/2 tank gas, Spare tire in place

edesign45 (and some others) wrote that all vehicles were weighed w/ owners aboard so . . . . your car --- at 2376 lbs/1078 kg --- must be lighter still?

Well, I did skip breakfast that morning.

Yes, I was in the car when it was weighed and I weigh about 185 lbs.

As a reference point, the last time I corner balanced the car with 1/2 tank of fuel and no driver the car weighed 2188 lbs.

. . . = 998 kg

Wow

Rick,

I think am going on a diet..loose that weight...then we can go faster..

. . . = 998 kg

Wow

As long as 1059 was @TLG for service anyway, I asked Marco to tank her up, weigh the Nasty Car . . . just 'cause . . .

Front = 1161 lbs/527 kg (49%)
Rear = 1214 lbs/552 kg (51%)

Total = 2375 lbs/1080 kg

(For reference, 1 US gal of gasoline = ~ 6 lbs/2.7 kg)



Coupla things stand

First --- tank-up an Early 911 and the alleged rear-weight bias pretty much evaporates . . . in fact, I'd call that 49/51 split just about ideal

Second --- where in the he!! did this S pick-up 200 lbs vs Bert's T?


I figure just the weight difference alone is worth, maybe --- 20 hp? . . .

I had a chance to weigh my car again last weekend. Current weight (without driver) is 2236 lbs. As weighed specs are:

'77 911 chassis with no sunroof, a/c, pw windows, radio, or rear seat backs. Recaro SRD seats. All stock glass windows.

'91 3.6 engine w/ plastic intake, 915 transmission w/ lsd, lightweight starter, '86 oil cooling system.

Backdated 9" fiberglass front fenders, hood, bumpers, ducktail. Metal 11" rear flares.

9&10.5x17" Zuffenhaus Fuchs with 235/50 and 255/50 Toyo T1R tires.

1/2 tank of gas, optima red battery, 16" 964 RSA spare wheel/tire in place, jack and tools included.



We also weighed a '73 RS inspired car ('69 912 with '86 3.2 drivetrain, RS flares, 7&8x16 Fuchs). That car weighed in at 2386 without driver, 1/2 tank of gas.

Some of the things that stand out for me . . .

1) 914s aren't that light!

Rick

I'm surprised you would say that since:
A) it's the lightest car on the list, and lighter than all but the lightest 3 911s by 100lbs.
B) it has a 3/4 full 100 liter (45 gallon) tank, that's 34 gallons which is ~211lbs of fuel

Stock tank is 16 gallons just like 911, and most were around 1/2 tank so subtract 26x6.2lbs = 160lbs to weigh in like most of the ~other~ cars and now you have a 914-6 weighing 2200lbs WITH driver. This list is also missing a bunch of other details about a modified car that would influence the weight. Yeah he has fiberglass decklids and bumpers, that's worth 100lbs (still the lightest by with that). But he may also have an all aluminum 3.0+ engine, which adds back 50+lbs.

And what's the point of with weighing a car with the driver (unless you're corner weighting)? That guy could have been 300lbs!

So, obviously I've shown my hand. I love lightweight cars and I love my 914-6. I weighed my chassis totally bare except for doors (no glass, no decklids). Undercoat and other various sound deadening was still in place (as well as the half inch of bondo I found on the rear quarters!). Only 575lbs. I can lift the front end off the jacks with one hand! I can easily see a flared 914-6 having a lot of bondo used if not done right. Could change the weight by almost 100lbs.

Any one know what a bare 911 chassis weighs? Everything else mechanical we bolt on a 914-6 is almost identical. Bring it on

cheers,
dug

PS. I still want an early 911, but I'm lucky I got my 914-6 when I did

[a911s]

I have driven two 911/912s that were 1800 lbs or less. Both had hot rod 2.0/2.2 911 motors. You would not believe how different they felt from a typical 2300 pound early 911. I can't even imagine what Kurt Zimmerman's car feels like...
