A lot of GT3 owners are a bit pissed - even the GT3 RS weighs 3251
I totally agree and to reinforce what may be happening, I'm hearing Porsche started to change when the 993s came along. I've heard from several sources they think the 993 is a beautiful car BUT it's performance is piggy in comparison with the claimed weight and HP. Customer cars should perform better than they do. In particular you'll see some performance shops having a hard time getting the claimed HP on their baseline 993 engines. This makes it hard for them to sell improvements if the engine only meets claimed HP AFTER the modification.
To be fair, much of the HP loss could be from deterioration of the premium fuels we have to burn but there remains the weight issue and that is Porsche's.

,,, Anyway, having half a tank or enough to make it through the day usually will suffice everything that I need and not having to be fully loaded causing excess weights and sluggishness in corners, off the line, etc. As long as you can plan out your trips to the next fill,, you can be half a tank lighter than any day with a full tank.

Then again,, leaving my portly Gfriend behind is always a good thang, too! Less nagging!

993 engines are pretty healthy suckers - I had one. BUt the 993 it came from......
With cams and headers (added 10 hp) it put out 280 - AT THE WHEELS ;-)

Worked well in a 2450 lb 911SC!

Would I save weight by filling my tires with helium? LOL
I know that some tire shops advertise using nitrogen instead of air to fill tires.
I bet I could save a few milli-ounces, better even because it is unsprung weight!
It is hard for me to believe that you could save 500-600 hundred or so pounds by stripping items like a/c, glass, and some insulation.
Does anyone have a listing of how much these items really weigh individually to see the direct benefit of removing items?
With this info one could make decisions on what to change out first for the greatest effect.

I sure like your combination of light weight longhood and high HP. I'm shooting for less than 2000#

Here are some webpages with that info:

http://www.early911sregistry.org/jCalzia.html#Calzia%20article,%20top

http://rennlight.com/

I saved about 300+ pounds with all the basic removal items plus fiberglass bumpers. My car still has all the appearances of a luxury interior, and still has a CD player. No AC, but I get blown air through those AC vents which are still under my dashboard. I still have normal, comfortable seats.

Doing the lexan windows and fiberglass fenders and such is getting more extreme, but people do it all the time. I want my car to feel 100% vintage and normal so I don't go the final mile in weight savings.

930 Curb Weight

So did we ever figure out what a 930 actually weighs..



I see 3000 LBS here but all over the net and on many ferdralzation labels on 930s the weight is always stated at 3600 LBS..

When I corner balanced mine it was 3,052 with 170lbs of Dumbbell weight in the drivers seat. So my 1979 930 is 2,882lbs empty.

Jim Tweet removed the sunroof from his 79 SC build and it weighed 49lbs.

And I mean actual dumbbell's, not me.

Mine is down to 2730lb with my weight in it and 30l fuel.
Sunroof, power windows , AC etc gone.
The factory handbook with mine says curb weight 2866lb. Not sure how they managed that. Maybe flat tyres :-)
