I've done that several times with older American cars I've owned. Not proud of it, but it worked. That's good stuff, IMO.

USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine. The vessel was the first submarine to complete a submerged transit of the North Pole on 3rd August 1958.


Bar's Leaks Stops Major Leak in USS Nautilus
During the legendary trip of the nuclear submarine USS Nautilus, Bar’s Leaks is used to stop a hidden leak in one of the vessel’s nuclear reactor steam condensers, which allowed the submarine to complete its historic mission as the first submarine to travel under the North Pole.

Well, here's one I personally had never hear of, with unverified info from the 'net:

The Porsche 909

"All-aluminum chassis, titanium suspension, loom silver wiring in place of copper, and balsa wood ballast resistors for the ignition system. It had a nitrogen-pressurized titanium/rubber Kugeltank fuel cell, pressurized so that Porsche didn’t need to use a fuel pump!

Chrome plated beryllium was used for its brake disks and powered by a 275 horsepower Formula 1-derived flat-8 engine.

The car's weight? 850 pounds!


Porsche got the weight down to 763lb for the final version of the 909 hillclimber (according to Porsche 917 by Peter Morgan)

The body was paper thin as well. They must have spit gelcoat on crepe paper. In the museum they have a an unpainted body display held up by a few wires and you can put your hand behind the body and just about tell the time on your watch. The 909 was actually called a step too far by several engineers. It could only be used for a single season as the chassis was distorted and needed to be replaced. Porsche decided right away that they couldn't sell this car to privateers as they had with other models. It also created a lot of ill will towards Porsche by hill climbing organizations. Imagine NASA engineers showing up at an amateur model rocket competition?"





Mask to avoid toxic fumes coming off the brake disks?

My favorite ever racing car, a master class in lightweight design

Closest I've come to working an an ultra'lightweight race car is this one

The 2000 season Benetton B200 F1 race car, driven by Alex Wurz (as seen in the photo) and Giancarlo Fisicella. It wasn't the fastest by a long way so needs must the team needed to do something drastic to make it a more competitive car.



Now for some details of the sort of tricks we got up to all in the name of finding extra qualifying performance

Renault V10 3ltr engine used magnesium heads instead of alumnium, these would do not much more than 12 laps before they would warp. Also I'm sure the revs limit would have been raised (not sure what it was but it would have been nudging close to 20,000 rpm), fuel mixture leaned to the max, minimum viscosity and capacity of oil used to squeeze out a few more horse power

All electronic sensors not required for the car to talk to itself so it could run on the track eg ride height sensor, brake pad wear sensors, suspension pushrod load sensors etc were removed and a cut down wiring loom fitted

Exhaust pipes were made from 0.4mm/0.016" thick Inconel tube, these would crack both at the welds and wear the metal was stretched during the forming of the bends

Bodywork was one layer 0.15mm/0.006" thick carbon fibre on the outside and a 0.09mm/0.04" thick ply on the inside of 3mm or 1/8" thick paper honeycomb. You could see pin holes of daylight shining through when held up to the light

We looked at self adhesive vinyl film instead of paint, this was heavier so the car was painted with one light coat of topcoat colour only, iooked fine on the TV but up close looked dreadful. Even using the lightest of paint coverage 20-30% of the total weight of the bodywork was paint

Old race worn carbon discs and pads were machined down to the bare minimum of thickness

The race fuel bag tank was replaced with a minimum capacity fuel tank, just enough for the car to splutter back to the pits on the last of 3 lap runs

The aluminium oil tank was chemically milled with patcwork of lightening pockets down a thickness of about 0.6mm/0.024"

A lightweight drivers seat was fitted, from memory it weighed around 0.6-0.7kg/1.32-1.54lb

The gearbox had the first gear ratios removed as no standing start required and I'm pretty sure every other gear was turned down to the minimum thickness before the teeth would break off. As reverse gear is required by the rules this was made in aluminium and the lightest viscosity oil and minimum capacity was used.

The lightest sets of tyres were picked form the range of tyres available to the team

All composite parts like the chassis, front wings, rear wings, floor etc were the lightest from the range of weights from the range of parts manufactured for each race

Think there was also a lightweight steering wheel with only the minimum number of buttons and swtches required

The single piece forged magnesium race spec. wheels which always cracked after about 2000km or 4 race weekends were lightened, the rim thickness was machined down to 1.9mm/0.075", wheels would go egg shape just from seeing a kerb or rumble strip, usually only got 12 laps out of a set

Mission accomplished as it pushed the team 3 or 5 places up the grid and when you push the legal limits of the rules you know you've done when there is a rule change to stop you doing it again.

I liked to get up on the roof and watch them go round and round. My old Brownie box camera did not take very good photos buy I had fun.

How cool would that be to own one?!

I can only hope this becomes real sometime during my lifetime....

Not where you'd expect to find a connecting rod while at 10500 AGL.
