That 787B was vastly underpowered. Mazda's goal was never to win Le Mans, and it was quite literally on the same performance levels as Group C2 cars. The 787B was just a marketing tool. And when all the top dogs such as Mercedes, Jaguars, and Porsche began to broke down the Mazda still went on. And you can guarantee they told the drivers to drive as cautiously as possible when they realized they could win. The best Le Mans engine is probably the Flat 6 turbos of the 956 and 962 since they could produce a ton of power whilst being reliable. So I doubt a 1000 horsepower probably 10k+ rpm rotary engine would survive very long.

Interesting video from Jimmer. The main reason Formula One cars don’t have Rotary engines is their absurdly heavy fuel consumption. You can add to that their pollution from burnt oil. Racing rotary motorcycles like the Norton used to trail a blue haze behind them, worse even than the average two stroke. Back in the day, the patents surrounding the Wankel engine were pretty all-inclusive and it took a hefty fee to buy membership in the club. This benefitted no one but the Wankel family. I’m amazed Mazda persevered as long as they did. Lot of power for the weight though.

I'm sure Rob will pop in and correct me if I'm wrong, but I think the "rotaries don't have torque" thing comes from the fact that most people are familiar with the 2 rotors from Mazda, but the 3 and 4 rotors seem to produce a ton of torque. Also, the displacement on those V12s was crazy small, so they were always known for very low torque as well.

[@_gaszy_8925]

I'm pretty sure it's also because when most people thing torque they think lower rpm, where as rotaries are only top end torque

[@griffinfaulkner3514]

NA rotaries really don't produce that much torque. Turbo rotaries, on the other hand, can build massive amounts of boost very low in the rev range, and as such can produce so much torque that it threatens to damage the eccentric shaft.

I ended up having to make my own tires in order to handle the power because the tires would spin in every gear. Edit: I looked it up before I made my engine swap and the 26b is actually heavier. It's actually6 double the weight at 400kg vs 200 for the V12.

[@ManWithBeard1990]

The rotary engine would be more compact but probably quite a bit heavier: As far as I know, all rotary engines produced by Mazda themselves use cast iron side housings. Aluminium ones do exist but they're not made by Mazda.

There's no reason you couldnt make the housing out of whatever. The problem is the apex seals.

Seeing those 2 trophies at the back thinking how far jimmy has gone. Our shedboi is a pro race winner!

[@Mercman1010]

That 787B engine could make over 1k HP. All they did was increase the Rev limit. It was limited to 9k for the race for durability reasons. It was dynoed at 10.5k rpm during testing

Congrats on the Donnington win! great video as always!

[@littlestan6625]

Hover well, Marshall 🙏🙏

[@jedcooper4205]

i’m enjoying beardless jimmy hope he sticks around

[@samacw]

15:14 is a great post credits surprise

[@StevenQ74]

There was also the Coloni-Subaru with the 12 cilinder boxer engine

[@TheWildSlayer]

Wow it sounds like Red Bulls' RB6 and it's amazing

[@P.L.J.V.]

I think about an old Fiat 500 with a Rotary,can be brilliant! :D

[@scotthecarnerd1995]

Always makes you wonder when these questions start rolling around 🤔 Great video as always man ❤️👍

[@derpherbert3199]

Hover-Marshall and Drincc-Well Oilman have movienights each thursday.

Now that would be the true challenge to see who builds the best rotary in F1

[@Stuntman175]

Supposedly, Mazda engineers tore the engine apart from the 787B after its win in 1991 and after inspection, they discovered that the engine could be put back together as is and run another 24h without fear of failure. Rotaries hate low revs, lugging and running cold, what they need is to be run like a race engine.

Didn’t watch the video (don’t cry I will) but just imagining that sound omg It would be so incredible.... 20 to the limit developed rotarys omg 😍

[@jamescampbell1070]

FYI, we even had a boxer engined F1 car, the disastrous Subaru powered Coloni from 1990

[@Xiploc3991]

Congrats on the win last weekend jimmer!

The only reason there have been no rotary engines in F1 is the engine specifications have been too restrictive. I was told it is a bit too difficult to calculate the displacement so it easier to stipulate reciprocating engines. It is a same because if the amount of work that had been poured into reciprocating engines had been out into rotary they would be better.
