whats the stock weight on a 911SC??

[shamrockcustoms]

I have been searching everywhere and have not been able to come up with a weight for a 79 911SC.. Can anyone help? We got my car running today after a long winter of weight reduction and came up with a weight of 2300lbs with a full tank of gas..

thanks

Sounds a couple hundred lbs light to me, especially w/full tank. My 82 RoW w/o AC is supposedly factory spec. 2500 lbs, but don't know how full the tank is when weighed.

[shamrockcustoms]

well thats good then, thats was the plan..LOL

BUMP... I find it hard to believe that no one on here knows this number that Im looking for

My 1979 911SC weighed in at 2550lbs with the following mods:

Fiberglass ducktail
Removed AC
SSI's and M&K muffler

I would guess without the changes it would be at least 100lbs heavier.

Hope this helps

I was thinking it was in the 2600lb area myself..


thanks

The official weight of the US coupe was 1190kg (2624lb) with no options, but all fluids and a full tank of gas.

The official weight of the ROW coupe was 1160kg (2558lb) with no options, but all fluids and a full tank of gas.

The easiest way to cut about 120 pounds is to weigh the car without gas in it.

Sounds like you have been very effective with the diet this winter. Seems you have got rid of something like 150 kg, which is superb. You still have a wheel and a something to sit in, don´t you ??

Hey Jack,
I don't know if that does matter in the States but in Germany when the car manufacturer states weight in the car documentation than they calculate like this:
Car with no option + average weight of a driver (68 kg) + 7 Kg add. weight (for tools, etc....) + 90% of a full tank.
In the earlier years (80s, 90s..) they just considered car weight with no options + average weight of the driver + 100% full tank.



that makes is more complicated, right?

yeah we went all out..
fiberglass hood, trunklid, bumpers, doors, lexan windows all around(actually we still have glass in the doors right now) removed all the sunroof parts, removed full interior, fiberglass dash top.. OH and this is also with pretty much a full rollcage...

Nostatic's numbers are on target, I'd say. My car, with about a third of a tank and no driver, no spare, no nuthin', weighs about 2450. I've removed the entire A/C system, backdated the exhaust and heater systems, removed the engine sound pad AND the rear deck insulation. Also, the rear valence and the rocker panels. So you see, these cars don't just naturally weigh in at a svelte 2300 lbs with a full tank of gas. An SC of that weight has been substantially lightened, somehow.

????????

Put more plainly, 2300 lbs with a full tank of gas is substantially LESS than stock weight.

Another way to state this is that either:
1) This car has been deliberately lightened or
2) The scales you used are way off.

Quite frankly, 2300 lbs is a proud "target" weight. Lots of guys would love to lighten their cars down to 2300 lbs. I've lightened my SC substantially, and would need to lose another 200 lbs to get to the weight of your car. If I changed seats and bumpers and installed fiberglass panels I might.....MIGHT be able to get down to that weight. If your car does not have these improvements, then I am quite suspicious of the scale you used.

My 78 is 2680, full gas, sunroof, Optima battery, roll bar, spare tire, A/C (w/o compressor), factory bumpers, Recaro SE seats.
Mods not accounted for are turbo, 18 lb Flowmaster muffler (soon to change to 6 lb M&K), delete cat, delete A/C (about 50 lb total of A/C stuff), two gallons of water in the washer reservoir. I'll post the new weights in a few weeks.

I could maybe trim 100 lb of bumpers going to fiberglass, 28 lb with an Odyssey instead of an Optima, 30 lb removing the spare tire. So, 2400 lb is a reasonable lightweight expectation for a street/track car.

I'm surprised with all the fiberglass you can't get under 2300 LB.

PCA Club Racing listed the car at 2552 when the weight did not include driver. After researching pretty heavily I learned that as Jack said, Porsche weights include a full fuel tank.

FWIW my sunroof coupe SC G-class race car is about 2525 lbs with a 1/4 tank. It's had almost all legal lightening done (except sunroof) but also has the weight gain of a 4-pt cage, 17" wheels/tires, 5L fire system, harnesses, front oil cooler, window net, strut brace, heavier t-bars, heavier sway bars, kill switch, transponder, SSI's, and a couple of other little doo-dads.

Wow, you really read between the lines.

you must have missed my post earlier in this thread..that was the plan to lighten the car as much as possible..we did switch out to a ton of fiberglass and stripped as much as possible..I was curious of the stock weight to find out my weight savings...

2300# seemed like a rational weight given what was gotten rid of

Getting back to what I said, this is what we did to "deliberately lighten" the car
AC delete
sunroof and all associated tracks delete
Fiberglass front fenders
Fiberlgass hood
Fiberglass front and rear valences
Fiberglass doors
Fiberglass dash
Carpet delete
Back seat delete
Sound deadener delete
Stock seat delete in favor or Corbeau buckets
Rocker trim delete
Drip rail delete (not that this saves much weight)
Lexan windows
M&K muffler
Odyssey battery
935 Fiberglass mirror
SSI exchangers
Radio/speaker delete
Cold-filtered Helium in tires

Heres what was added:
Full roll cage made of PVC pipe painted black
(just kidding, its 1.5" DOM tubing

So, basically, if you read this post carefully, you may note that we did some little things to lighten the car.

HA HA Have a great weekend Car will be on the road soon

Shahram - Thanks for that info - it's very interesting. Are both methods DIN specs?

If so, do you know what DIN numbers they each are?

Also, do you know how they calculated the weights in the 1970s and/or 1960s?

Thanks.

Got an attitude today, Jay? Yes, I read your opening post. Your lightening efforts were not spelled out. That's why I said that 2300 lbs is not likely achievable without extraordinary efforts. Again, not knowing what you might have done, I stated it this way: "If your car does not have these improvements, then I am quite suspicious of the scale you used."

Now, if you think that input is a call to arms, then you might want to meditate a bit before attending any critical meetings today. Good luck with your racing/modification efforts. At this point, to lighten the car further, as I'm sure you are aware, you'd need to use a drill.

[chrisp]

Compared to mine I would have guessed that yours is lighter than 2300 lbs. All that fiberglass, no sunroof, lighter battery, lexan everywhere has to get you more than 225 lbs.
