weighed the portly boxer yesterday...

That would still be around 3275-3300lbs dry, not bad considering the xtra weight BBis have from the added parts, a 308 weighs 3200lbs dry to keep things in perspective.

 

You shouldn't just neccesarily scale that result in a perfectly linear way. All you really know is that at 114 lbs, it indictes 121 lbs so maybe you should be saying 3502 rather than 3509

Measuring a ~100 lb object on a scale capable of 5000~10000 lbs as the "calibration" isn't the greatest IMO (unless you're interested in weighing other ~100 lb objects). At best, the scale probably only has a gauranteed accuracy of a couple~few % of the total capacity.

 

The 365 weighed around 2740 from the factory, this was without a/c and power windows, don't think I have heard of a 365 without either so they claim 150lbs+ adding these options that would be around 2900 lbs dry or 200lbs less than a 512BB at factory 3084 which is accurate IMO as my car weighed 3300 with 1/2 tank and misc items and tools.

So if your car is at 3275-3300lbs dry an extra 400lbs is possible for a BBi and 200 for a 512BB, I could see the 365BB around 2900-3000 dry.

 

Same general problem as dynos. Take the cars to the same weigh station.

With just a modest improvement in torque the 512 kick as* in terms of tq/lb which is the important cruising/street measure. The little v8s that generate 350+ hp (not tq) at 8000 rpm are not the same as the 12s below 4500 rpm. As an owner of a German (sorry) 516 ft-lbs @ 2750rpm machine I can attest.

 

Are you SURE your girlfriend is only 114? If I were you I would question her to see if she is telling you the truth about the reported weight.

ps - before doing so, make sure your financial affairs are in order.

 

Having seen both Newman's girlfriend and his car on Sunday, I can vouch for her weight estimate. Not sure about the car's weight though. I can also confirm that both a very nice looking indeed.

I weighed mine on the way home from a recent Ferrari Club event in Cannon Beach, Oregon.

The weigh station was closed, but they left the scale display turned on.

It registered 3,500 pounds, which including some luggage (20-25 pounds?), all of the tool/jack kits, spare tire, etc.. and about 1/2 tank of gas.

1983 512BBi (It's been returned to Euro specs and has a Larini exhaust, which is about 30 pounds lighter than stock)

 

My wife was too fat for the doctor's scale so he took her to a truck weigh station.

 

As long as she was carrying tools/jack and had a half tank of gas, we're all good.

 

I weighed a Carb BB with Bell sports exhaust (very light) some time ago and it was 1515kg with lowish fuel.

I have scales and I have both 365 and my own 512 in the shop... i'll try to find the time to weigh them.

 

Approx 3,500 pounds sounds correct. 2740 for a dry 365 BB, will not happen on an accurate scale. - That dry car is probably in the low 3,100 pound area.

 

The first wrong assumption is the accuracy of the doctors scale. I had a high reading on one at the clinic some years ago, and this cute nurse let me try every scale in the place. Simply because every single one I stepped on was different than all the others. There is a reason they print "not legal for trade" on those worthless things. The truck scales are generally much more accurate. I would be surprised if its off more than 10 pounds.
