Why Does The Porsche 917 Need Two Batteries? ⚡️

[@quademclemore7568]

That livery is fucking beautiful

[@exF3-86]

Nothing unusual about the external battery start in older sports and open wheeler cars. Most FIA reg open wheelers up until the 90s ran a total loss system (no alternator). It wasn't an issue because the instruments (mechanical) and induction (carb or mechanical fuel injection) didn't draw current. The only draw was ignition and the rain light. Sports cars had a small alternator for lights etc especially for longer endurance but it sucked power when every hp counts and was another thing to break

[@yoslauda4714]

It was the time when electricity wasn't the great friends of motorsports

What an interesting car. N the background stacked as well 🥵

[@camerons6028]

That sl300 just siting there looking so good tho.

[@IR123]

That was one of the most insane car line ups ive ever seen!

[@pollarispatrick]

I believe it also has gas in the tubealre frame to make it even lighter...

[@ren9839]

That was a misconception and kind of a conspiracy theory amongst the racing teams in order to get it disqualified. They did fill the frame with air but it was just normal air from a compressor. They did it because (im pretty sure) the tubular frame was made from aluminum and during stops theyd check the psi to make sure the frame didnt crack.

[@TempSlothy]

also adding helium or something into the frame doesn't matter as much as you may think. Weight is not the main concern, it's mass. You actually want the car to have the most weight on the wheels with the least mass (using aero). The difference in mass between helium and air is effectively inconsequential, and it would probably cancel out any benefits by taking weight off the wheels.

[@not_even_me5035]

It was filled with nitrogen because the tube frame was built with almost 0 redundancy. This allowed them to check for breaks in the frame by monitoring the pressure.

[@yoslauda4714]

​​@@ren9839ut wait, did they depressurized the tubes before went to the grid?

[@michaelbrady9056]

​@@yoslauda4714Nope! As others have stated, they could check the air pressure inside the tubular frame during the race (pit stops, etc) as these cars did endurance events (6, 12, or 24hr races). If the pressure fell, they knew the frame was "leaking" and thus had a crack or hole in it. The Germans were and are amazingly clever engineers...

[@Proven_Data]

I’m sorry but I was looking at the 300 SL in the background the whole time. 😂

[@Person-cv9dj]

[@ConstanceMists]

Not the DBR1??? The 300SL isnt even the most valuable or rare car in the shot by a mile

[@Proven_Data]

@@ConstanceMists Nah, also the 300 SL holds a special place in my heart that's mainly why. The SLS is really one of the first cars I ever paid attention to. Which as you probably know is the reborn version of the 300 SL just like the AMG GTS is the reborn version of the SLS and 300 SL. But when I was a kid I really didn't like classics until I saw the 300 SL. And now I'm crazy for classics. Like my favorite right now is the 1966 MKII GT40.

[@TheWolvesCurse]

fun fact: the engine of the 917 is not a porsche typical boxer type flat engine, but rather a 180° V12 flat type engine. the difference is that in a boxer engine each piston has it's own crank pin, in v-type engines 2 pistons share one crank pin. therefore in a boxer engine opposing pistons reach TDC simultaneously, while in a V-type engine, opposing pistons alternate when one reaches TDC the other reaches BDC at the same time.

[@achimhaun2726]

A very good friend of my dad, Michel Weber, came third at Le Mans in a Porsche 908 Langheck in 1972. At one point during the race, he hit a bump on the mulsanne straight while going 200mph, flying through the air for over 60 meters before landing again. He said that during the air time, he could see the car falling apart around him in slow motion.. Great guy, but sadly he passed away about 12 years ago

To be fair, race cars don't need big batteries... Battery just needs enough juice to start it

[@rt2255]

You know how much cranking amps it takes to turn a real high compression race engine over enough to crank? More than most truck batteries have

[@DrSabot-A]

​@@rt2255That's exactly his point, most racing vehicles use external power and/or starter because it only needs power to start the engine. The rest is done by the engine afterwards

[@rt2255]

@@DrSabot-A yes and he said battery on car only needed to crank it and most race engines as you said use external as internal would have to be huge

[@rt2255]

As if internal would be used for cranking read his post carefully said battery pnly needed to be big enough to crank most race cars internal is back up tp alternator for gauges pumps etc if alternator fails, most do not have batteries on board large enough to crank

[@Prodriver33]

It can start with just the little battery if it cuts out during the race and needs to quickly be restarted. But only try to start it a couple times till the battery runs out and it can’t start the engine when it’s cold only when it’s been racing and is already warm.

Fun fact the chassis was aluminum and part of it transported the oil from the tank to the oil pump the other part was sealed and pumped with either air or Helium (depends on the story) to make sure it didn't crack and eventually break. If it leaked or lost pressure time for a new chassis, as the metal is at it's fatigue limit
