How Fast Can The Rotary Powered Mazda 787B Lap The Nordschleife? 

zicada I'm betting he can do a 3:27:54.972

Average waling speed is 5 km/h, track is close to 20 kilometres. So he will do sonething 4 hour-ish

Cake Doge with elevation add at least 30 mins

LOL

That is an indeed very creative way to write "Nordschleife"

repcsi wow that’s awesome! A real piece of history right there and it shows how reliable that Rotary engine ended up being!

In race tunes, Wankel engines are very reliable. They can premix good 2 stroke type oil in the fuel, which keeps the apex seals lubricated. The lack of reciprocating internal parts means constant high rpm use does not cause excess wear, though going too high can lead to apex seal chatter and housing wear as they bounce over the lobes in the housing. I am curious how much of he current engine is the original race winning engine. Wankel engines have a bad reputation of needing rebuilds, but they are also quite simple to rebuild. Think of the Wankel like a Dagwood sandwich. Outside housing, rotor housing with rotor, internal housing, etc etc etc outside housing. The "block" is actually a stack of different parts. You replace any parts that are beyond usable spec.. you don't replace the entire "block" since it doesn't have one big block like a normal piston engine. FWIW, I had an RX7 and RX8- almost 20 years ownership combined. They are great fun to wring out daily but also need proper maintenance/care to last a reasonable amount of time between rebuilds.

But are the apex seals as old as the car itself? 🧐

@@fatbor2078 are the rings of a piston motor the original after racing? Are the valves the same? Are the belts and timing chains the same? Every motor has its points that need replacing.

@@domesticterroristAtari dont be a jackass

i think they had a gearbox from porsche and it couldn't take the full power so that's why they ran it with 700hp... not 100% sure tho..

you're not allowed to run a qualifying spec car during race, the lap times show it was slower than most of the other things on the field

Xerro No Vatimo slower means very little in an endurance race as Porsche has shown Toyota the past few years.

they were also less reliable than the competition before everyone got hit with regulations, the gap in lap times is also bigger than most people think

ASoldierify but have you seen Toyota's luck? No wonder Porsche keep taking pole

While scrolling down the comments I was hoping that someone commented about that. Cheers mate

Fallen Maniac lol

Mazda has done it more then once to. the 757 the 767 and the 787 as well as the IMSA GTO Rx7

In fact it was so good that they banned the rotary engine after this race because it made so much more speed with such a small amount of cc

I wonder what would happen if they made a reliable rotary the size of the other competitors engines.

Fallen Maniac for street use or racecars

I wish it was like that in the Gran Turismo 7 cockpit view. It annoys me when most of the time the driver’s hand just sits on the shifter when it doesn’t have to be.

Xarcotikz He has the right pitch and he is so excited that he would be perfect for commentating

Him and super gt

lol_commentating while racing_so intense

Actually that's insane. I wouldn't be able to comment while racing. I would just leave a comment after racing and then put it on the final clip. How focused he would have been on real race without talking.

@@EvanMoon and the british accent too

just curious, which prototypes sound better you reckon?

DieterS. The Sauber C9 is probably one of them. The 919 also sounds beautiful.

DieterS. The Jaguar XJR-9 because of a screaming V12 and the current LMP2’s because of the combination of how they accelerate through the gears and decelerate with a ton of turbo anti-lag.

Agreed on the sound. I was lucky enough to hear it run in person at Laguna Seca a few years back.

Nobody liked it back then. It’s become this silly internet legend.

Nasty Pasty normie

Yea the 787b isn't at its full power

Not so much that they didn't make it to the end, more that they lost too much time repairing stuff. If they could get away with it. Even with pit crew speed, it's faster overall if you don't need to fix anything

Yea, Toyota told you that.

ik this is 4 years old but i bet it could be one of the fastest cars on the track if they had a different gear box coupled with the 930hp it could have done. Since the engine was the most reliable part of the car. If the engine actually was able to do another 24h race unlike many of the other car's engines, then Mazda was definitely limiting it with what it could have done.

Alejandro Aznar lulz

i mean its working now

Alejandro Aznar making 1000+ hp :)

jtfoog got pop up headlights now

Flat bottom car now

didnt expect you here

Always around here

You can come and race the 906 on AC as well as Forza mate :-)

African or european?

These are the sort of things you have to know when your a king

Rotaries are anything but fuel efficient, so I'd imagine so.

Make that 200-300 KGs, the 787B was ridiculously low weight compared to it's competitors on that race. In fact, the 787B is the reason FIA banned anything with less than 1.000 KGs of weight from Le Mans from what I heard. But yes, it was by far the most reliable car on that race (much to the dismay of all the "lolololol rotaries are unreliable" folks), the fact the engine was still brand-sparklingly new when they disassembled the car post-race is an unique reliability achievement on it's own... but it wasn't fuel efficent at all. it drank more gas than your average finn drinks alcohol in the podium of WRC or F1 races, but the compensation came in form of the tires lasting much longer than it's competitors, resulting in less stops. For reference, in an interview with Isami Amemiya (Founder of RE Amemiya, legendary tuner of RE cars) here in RU-vid, Amemiya-san talks a bit about the days they raced in the GT300 class of JGTC/Super GT with a N/A 3-Rotor RX-7 FD3S. Ama-San mentions the car had the same fuel consumption of higher-class GT500 cars which was a drawback, but in compensation, they could go sometimes entire races without exchanging tires on the car, They won the GT300 championship title in 2006 with that RX-7. So while they aren't "fuel efficient", they are very efficient in performance and tire consumption.

Wulfe tires is what eats up lap time and pit stops in an endurance race The weight advantage comes from how light the engine was and because they didn’t make a lot of torque so you could lighten the drivetrain significantly

The reason car 55 won is because they knew they were the slowest car, so the team told the drivers to just go all out. Running fast laps the whole race, they were faster than the competition who were being gentle with their cars, and the car was reliable enough to take it for 24 hours.

@@coast2coast00 The other reason being that the leading Mercedes broke down. The 787b was a mid-pack car at best, its win at Le Mans was a fluke, and neither it nor its predecessors won any other race.

Yup. Engine was as fresh as a daisy after 24 Hours!

Once you hear the Zoidberg downshift, you can never unhear it.
