Those tires are hugeee

Not bigger than my pp

brand new STICKER tires!! $$$$

[@stevejarred6484]

@@hansgrueber8169 ... And, let's see... The sponsor stickers on the car read: "Firestone" but the sidewalls read "Avon"! What's next? A set of Good Year's? Maybe a set of Hoosier's? Match things up or scrub the paint of the sidewalls! Mis-matching the labels really looks sloppy, jarring and half-assed!

This and 787b are my favorite race cars ever

[@Niki_lauda76]

Same bro!!!

[@Kevsmopar429]

1977 (Jacques Laffite) Ligier Matra V-12, but I agree this Porche Flat 12 is a beast of a sound. It was said that the flat engines handled better in turns than the V engines. Both types were brutal on straightaways. Although the V-8 Cosworths were proven, as well and won F1 Championship in 77', if I'm not mistaken, by Mario's - John Player Special - Lotus/Cosworth V-8.

CLK GTR is also straight up porn 🤌🤌🥰

[@Bryan-jd7os]

Absolutely! 2 of the best for sure!

[@Bryan-jd7os]

The 787b is in a class by itself! Insane!

[@CrystalSmith-f1m]

I love this car for the tires tbh it’s so satisfying

[@jakehildebrand1824]

A true work of art

[@TheCanadianBubba]

Never knew they had on board starters... great to see it alive ! Thank you 👍

[@JohnDoe-gn3rg]

They had them because technically the 917 is a sports car not prototype and had to be homologated. It also has turn signals, a spare tire and luggage space to comply with rules! At the time sports cars could have 5 liter engines and prototypes had 3 liters so sports cars were faster for a short period.

[@55Reever]

I love that car!

[@06emglobal]

Those 12 they have a nice roar !,

[@original2758]

The width of those tires; gotta be between 15 thru 18 inch width 😄 Essentially "drag strip" width wheels imo

[@cannedcheeseburger5593]

what a beast

[@roku_nine]

those tires are thicc!

[@SBT300]

For a race car the low idle is pretty smooth. And to get going from a standstill seems to be surprisingly easy....

Nice sound 👍🔥❤️

This was the fastest racecar in the world in 1970 as it reached speeds up to 248 MPH.

[@brotherjohnsmusic9491]

I wonder how much are a set of tires on this race car?

[@yoder903]

How loud do you think that is irl? Like my brothers Jeep has a 350 vortec v8 and it’s loud, wb a 917?

[@sammnnmm]

Bro in the back filming with an iPad 😂

[@arnolddamnit]

Why do they leave the spec stickers on the tires!! I never understood that

[@Maxsmack]

waste of time i guess, these guys change thousands of tires in their life and the 15 seconds to peal them off isn't worth it and adds up

[@arnolddamnit]

@@Maxsmack yeah but you have hours, days even. Why can't the take them off the night before. It's the tires... The one thing that separates the car from the track. The tires

[@Maxsmack]

@@arnolddamnit it wears off after a few hundreds feet of heavy use. 15 seconds is being generous even so times 1000 equals roughly 4 hours of time.

[@arnolddamnit]

@@Maxsmack makes sense

[@original2758]

​@@arnolddamnitObviously it doesn't effect the safety/performance of the car; considering even commercial tire shops do the same... Imo of course 🙂

I just want one chance to prove I am not qualified to drive this car.

[@LordRidler]

its more a 180° v12 than a flat 12 :)

[@LarsMarsCars]

A 180 degree V12 is a flat engine. If the cylinder banks are flat, we call it flat.

[@yes7797]

Since the difference between v12 and flat 12 is the crankshaft and not the angle of the banks, its a v12 180° and not a flat. As far as i know

[@LordRidler]

@@yes7797 correct

[@LarsMarsCars]

@@yes7797 the V is called a V because of the shape. A flat engine is flat because it's flat. That has nothing to do with the crank setup. The point you made is only valid for boxer engines. The 917 engine is not a boxer engine, yet it is a flat engine and not a V12

[@LordRidler]

@@LarsMarsCars it may be an flat V12 engine If you want to call it that way. Where i live there is no difference between an flat engine and an boxer engine. Technically you should call it an v engine but If you prefer flat its your choice. As you can see here: en.m.wikipedia.org/wiki/Flat_engine flat is not false but there may be understanding problems

They made a turbo version too with a 5.4L. Its probably one of the most powerful engines ever put in a road racing car.
