Great news! The 6 Rotor RX4 is returning, but this time for the 2014 V 4 & Rotary South Island Champs! It will be on display at the show and the drags on the 8th-9th November 2014 in Nelson, NZ. Full details on our website, or subscribe to check out all the videos next month!
I’m here in 2019. This thing is NASSSTYYY!!! Dude is just “Spongebob-ing” the throttle with his big toe and instantly sliding the ass end out! Such. A. MONSTER! 🏎 💨 😱
1 rotor = Gets you around town. 2 rotor = Loads of fun found in Mazda Cosmo / and RX line. 3 rotor = found in some RX8's but mainly just for racing. 4 rotor = 787B AMAZING power and Wins Le Mans 5 rotor = just inconceivable 6 rotor = face ripping / melting engine that puts everyone else on the road in the ditch as they think they are about to be killed when you pass them. Also can breath fire. LOVE IT!!!!
Only a Kiwi would be crazy enough to run something with 800 horsepower, in a car that weighs barely a metric tonne, and revs like a Formula 1 lol. A Formula 1 has the advantage of huge downforce to stick it to the ground, so anything wild in this would take some balls. Very well turned out machine. I normally don't like the sound of a rotary, but this one is an exception
However, this is a Mazda RX4. Have you any idea how many generations behind chassis-wise that is? Not to mention being a rotary and a relatively high torque one, it's akin to having an engine that can rev like a moto GP racing bike, but can do it in seconds, giving the kind of acceleration that would make it one hell of a handful. There's no turbo lag in this because rotaries can rev so much quicker than piston engines
At a conservative estimate, approximately 2500lbs. The RX4 was a very lightweight car. The weight of the engine over a rotary might add about 100lbs, but it makes a 1990s Civic look chunky by comparison in stock trim
Mechknight73 I want exact #'s. I had a couple Rx-7s and swapped parts with Rx-8 owners, and the guys that swapped corvette LS engines claimed an almost 90lb weight reduction from a 2 rotor 13b.. The car is clearly a drag car and is going to appear to be 'light', but what is the weight and has anyone made a 1/4 mi run in this thing yet?
Over 800hp out of a 3.9L displacement and no turbo. I don't think there's any reason to spoil the pure sound of this thing with a turbo. Especially considering how easily it lays rubber with those huge tires.
Ryan Chandler Oh dear you really dont know anything about rotary engines do you. Mazda quote the swept chamber volume as 654cc (look it up) Each rotor has 3 chambers. 654 x 3 = 1962cc x 6 rotors = 11,772cc Now you know why they absolutely drink fuel, hence they're no longer made.
I was going off how Mazda rates their engines. But my main point was that engine takes up a small amount of space for the amount of power it puts out. In reality Manoo is correct on how the engine should be rated, it's rated lower purely for tax and engine size rulings, albeit being completely incorrect.
My mom had an 86 RX-7 13B-T turbo with a 5 speed was a great car, bought it new and had it until mid 2000's never had any major issues besides a clutch, had 140,000 kilometers on it when she sold it.
sweet, 6 rotors when 20B has only 3, still one thing is missing - a turbocharger :D. It's scary now to drive this beast imagine it like twin turbocharged. Or one massive turbocharger. Though that way could be too much torque and wheels might spin out. How about RPM? does it operates on like 1k RPM? Or do you always have to keep high RPM?
6 rotor is amazing in its own right. you can't just turbo this, you can potentially go 3times+ horsepower with turbos, thought about fueling, cooling, chassis/drivetrain, engine upgrades needed to turbo this build?
Correction, fuel consumption of a v12, the price of a Lamborghini in apex seals and monthly rebuild materials BUT you have an engine that revs like a street bike. That's a win, I guess?..
yes, that's a win. definitely IF my calculation is not wrong, for 15 years engine rebuild every 75K = 5 years = 750$ X 3 =3000$ oil, maintenance, tax, gas, etc= 5250$ (15 years) service=1000$ per year = 1000 x 15 = 15000$ 23250$ for 15 years, that's not too bad
The sad part is, rotary engines get rebuilt MUCH sooner than that. They need new apex seals(complete tear down) about every 15K my friend. The one in this video probably gets rebuilt after every few races. There's a reason these engines are extinct. They're fragile, unreliable and have worse efficiency than a 2 stroke running a 5:1 mix. I just thought I'd inform you from a stand point of someone who has worked majorly with them. They are wicked cool, sound amazing and can make great power while revving to the moon. But a complete engine teardown every 10-15K miles isn't most people's budget. Sure, you can wait to 25K or longer but you'll burn a quart or 2 of oil every mile. They are horrible engines in reality, though us gear heads love them for what they are and what they can do. You should also be aware there's probably 75K or more alone invested in the one in this video. Not a really good power output for the money spent. 75K in the engine alone would get you well into the 1000 range in your other import cars, be it Subaru, Mitsubishi, Nissan, Toyota etc. You'd have a 1000 if not 1200 hp car for this amount of money. Though it would not be as cool as this 6 rotor.
If that's not Ervil Edenbaker's Popcorn Popper I don't know what it is. Who ever said that's gonna take the V8's is crazy! But I can't say anything but " Wow!" to the work that got put in and effort to make something that is truly amazing. Got to give it to Mr.Wankel too though.
Damn I love the way rotaries growl. This is an awesome engine, well done. But... This is also probably the worst waste of power I have ever seen. 6 rotors... in an rx4? Poor aerodynamics, a car meant for luxury/touring, and definitely not meant for sporting purposes. It's awesome, but it just seems... wasteful. There's no way that car is stable any faster than 80-90mph. On top of that, it seems that only a fraction of the power is actually reaching the ground. Notice that whenever he even touches the throttle, up the ass of the car starts to come out. Would have been awesome to have seen this engine in a chassis that could have actually utilized such power.
this was just a test run ... at Manfield, lower North Island NZ ... not really any other closed circuits available in that part of the country. And no turbo coz its already up in the 800+ horsepower region. And they built just to see if they could.
I just got a good idea! Build a 6-rotor not unlike this one, but have each rotor with its own turbocharger connected to its own exhaust (the intake and exhaust are almost continuous) so each turbo is independent of the others. Now you will have consistent boost even at low rpm as not much pressure is needed to turn a small light turbo.
not much pressure is needed to spin a small turbo but you're also not going to get much air out of one rotor. Overall it would be more efficient and MUCH cheaper to go with a twin turbo setup.
But, having multiple cylinders exhaust into a single turbo increases the temperature and makes ball bearings unsuitable. I meant to use relatively large low-pressure turbos for this, so they produce some boost at low speed.
In response to an email, PPRE assured me that there is a combustion event for every 60 degrees of rotation. 360/6=6 This is a non-mirrored eccentric. PPRE's explanation for the lower frequency is their 6-3-2-1 exhaust header configuration. I still say the 4 rotor sounds better.
Holy moly, Batman. A 6-rotor RX4? Haha so loud the video is distorted. Classic rotary music What's a drag racer doing on a road course? With those pencil front tires and tall slicks on axle-cut rear end that thing is sliding all over the track. Look at those rear sidewalls squirm.
You are correct and wrong. Yes is it not a factory option to get a 3 rotor RX8 but it is a very popular choice for RX8 racers or drifters. Note i said its for racing. Its a 20B engine and it works well with the rx8 setup. There is a full guide on how to do a 20B swap on the RX8 club website and a lot of people do it for racing purposes.
Not quite. Measuring total displacement of a 4 stroke is... cylinder volume x cylinders. It does not vary by cylinder arrangement/number. There is one combustion event over the entire displacement every 2 revolutions of the crank. Each rotor revolution = 3 combustion events. The e shaft rotates 3 times as fast as the rotors. So you get 6 ignition events per revolution of the e shaft on a 2 rotor engine. So 720 to = the 4 stroke engine and you get 4 combustions. On a 13b that's 654cc x 4... 2.6
I would guess, Or it would make pretty significant noise. Considering each rotor is 3 cycles per crank rotation.Plus you would need a specially made crank since more than 4 rotors was never used by factory teams. conjoining 2 3 rotor cranks would be best, though rotating them 90 degrees is easy, but you're right about exhaust note.
813hp at the wheels at 8,800rpm, 759Nm at wheels at 5,000rpm. No turbos, no nitrous, no methanol, just a bespoke 3,924cc peripheral-port rotary engine running on pump gas and breathing naturally.
I want to see what it can do with a equivalently sized turbo. rotary engines are well complimented by turbos by all accounts, so....why not.
hzuiel
yes did you even see the output unlike piston
rotary squeeze a lot of airs to the exit of the exhaust

There is one combustion event over the entire displacement every 2 revolutions of the crank. Each rotor revolution = 3 combustion events. The e shaft rotates 3 times as fast as the rotors. So you get 6 ignition events per revolution of the e shaft on a 2 rotor engine. So 720 to = the 4 stroke engine and you get 4 combustions. On a 13b that's 654cc x 4... 2.6

Considering each rotor is 3 cycles per crank rotation.Plus you would need a specially made crank since more than 4 rotors was never used by factory teams. conjoining 2 3 rotor cranks would be best, though rotating them 90 degrees is easy, but you're right about exhaust note.
It will be a street legal drag car. Can't wait to see what sort of times it can pull off.
naturally aspirated rotary is wicked, turbo just killed it
that moment when you take a drag car on the road course 🤣🤣🤣 but seriously that thing is dirt nasty.
From the technical aspect is it like a wunderful woman.
6 rotary is very fastonating.
Respekt from german rotary fan!
