PPRE 6 Rotor RX4 Track Test at the 2013 V 4 & Rotary North Island Jamboree (Onboard Footage) 

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 with such big areas for the air to enter...so yes rotaries are naturally meant and dedicated for turbos

its 11,772cc

Tiqo 654x6=3924

Logan Smith 3924x2=7848 litre V12 piston engine as Wankels produce twice horsepower than piston on same size

Eddie Vasquez they should, and they did.

The answer to that is, yes, yes they should!

4 times the power ,but 4 times slower round a track, oops..

@@neilblackman2965 it's a drag car they put on the track here. I don't think people expect it to be fast doing laps.

@@butwait Thanks for clearing that up.

"yeah my car idols like the faceless" lmao

Herp Derperson Idles*

JohnnyNismo 8 rotors o.o

Direct injection triple bank 12 rotor.

Not hearable

Funny how all of a sudden, I found my way back here. Good things always come back around :D

The scream is so awesome😍😍

FCUK YES!! down the quarter mile - or was it not built for that?

we do want please

RapidFire Muzik Not enough testing done for that yet unfortunately.

algood, still a car to drool at for some time tho :o)

Ask this; Who wouldn't? ;)

Go check out a mid 2000s Formula One non-turbo V8 or V10. Just shy of 20,000 rpm from some of them, and a shriek that only a multi-rotor engine can compare to.

Dr. Bananable Lector Is he doing a 6 rotor as well

@@kairone8623 Yep

@@kairone8623 his latest commitment already getting a crankshaft made

but think about the amount of power this makes vs a ridiculous 7L drag v8 or something and then how much fuel that uses

@@MadazMazdas you are missing the point of this build

@@notaberger_3216 how so?

@@MadazMazdas its unique

@@notaberger_3216 no shit, that's why I was here watching the video, rotaries are my favorite engine

punishbeer we all know car devs dont listen to their fans nowdays so all one can do is custom build his rotary engine with desired rotors 4-6 or more.

@@ckryses3962 there's a difference between not listening to fans and making something that would cost at least half a million. This is up there with the lfa in cost.

6 rotors = no mpgs

NissinTuner as well with 6 Rotors the amount of repairs that would have to be done on the motor would be insane

It has nothing to do with them not wanting to do it. It’s because of stupid and useless environmental regulations..

Lazarus D i watched them all twice bitch, i know my shit

Did I miss them shifting the 47 speed transmission? Sadface.

The slow and the curious

i went and got my head phones cause i needed it louder !

thats the spirit mr house hahahaha

Oh it wasn't a tornado

Huh? What?

Lol me

Very much so.

Indeed...quite right.

True

Mechknight73 Kids get 800hp out of 4cly Hondas here in America!

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

Mechknight73 Yeah its a crazy beast. I wonder how heavy it is?

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?

You mean 800hp from 11.8L

2 rotor is 1.3L, 6 is 3 times 2, 3.9L

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.

Manoo42 Ryan is still right

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.

500nm thats big

PCGamer90x I think it dyno'd at 500 ft -lb not 500nm, so it's actually closer to 680nm of torque EDIT: it dyno'd at least 560 ft-lb = 760nm of torque

Jason Lo lb-ft, that is to say; Pound-Feet! It's not 560 feet per pound!!! :P

Jason Lo You see, it's is a measurement of force over distance, you got the nm correct, x amount of newtons per meter etc, etc.

I always thought Rotary's weren't known for their torque? Rather their high rev's, and good power to weight ratio.

look at the engine bay , if that happen a lot more pipeing is needed

you can always find some room for turbo, be creative. Not necessarily turbo has to be in the engine bay

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?

***** Trust me, I'm amazed too. And for the turbo part I was kinda joking, but at the same time not.

I'm just going to make a engine that make 1000hp N/A and turbo it, umm no

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

i forgot all of the calculation doesn't include insurance, parts, etc.

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.

oh wow rebuild every 15k? that's insane premix not included too yeah, it's pretty dang expensive to run rotary.

The air in Australia is clean... No need for air filter. I actually have no idea what I'm talking about. Lol

Leslie H. *New Zealand. And to OP Air filter would ruin that beautiful sound 😩

. . . . . . probably ate them

LiracyMusic beautiful? ... Shits ear rape.

LiracyMusic no air filter will ruin that beautiful engine eventually

ithinkijustthunk That's just how we do it in New Zealand bro xD

I like this. But you need to be bill gates to do that

BATMAN haha

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.
