6 Rotor RX-4

I don't fully understand what are the hp benefits of building a motor with 6 rotors...at least not yet.
As somebody mentioned earlier, wouldn't a 4 rotor engine properly tuned provide an enormous amount of hp anyway?

That's kind of my thought... wouldn't an FI 3 rotor or 4 rotor be way more than enough? If they're just doing it just to do it, I guess I can understand that. I'd just like to know more about the purpose. I guess it's obvious this will be a drag car... I can't imagine they're planning on making this a road course car...

Definitely a drag car...or maybe they just want to auto X it, lol

I'd bet that the purpose is "because someone had 'this crazy idea' one night"
As long as cars exist, people will be trying to make them faster, go faster, beat previous records. 20 years ago I'm sure they were saying something similar about the ~1,000hp cars. Tire tech advances just like everything else, and while high 2,000s mid 3,000s in hp sounds "too high" for todays tires, what about tomorrow's tires?
The assumption is that there is going to be some kind of turbo system for it, but it's possible they are going N/A. Just because we might not see a reason for that doesn't mean that they don't see a reason.
Motivations for the build haven't been indicated yet.

Well anything is possible really, my engine builder has already finished with making his own housings and plates, cast, with coolant jackets to suit any porting.
Also his own 4 rotor E-shaft fully designed for the 4 rotor, and coming to a rx8 on the otherside of the world from you.
If thats possible i cant see why people cant put more rotors on, so gl to the KIWIs

/\ Your Ball and Nut Steering Box will have to be heat shielded/protected.
Good god Mazda's back then were bloody awful steering /ride wise compared to todays product.
Apart from being cheap now, I have no idea why anyone gets excited about RX-4's, RX-3, even Capella's, YES very reliable, but just crude...1989-1990's were their breakthrough years of getting it right...the only exception was the first series RX-7.
1980's, Mazda improved on bodies/suspension (come in the RWD Mazda 626), but used bloody old drive trains, an Engine from 1968 just bored out and with air pumps added.
And I grew up selling genuine new parts for all these 70's cars..

haha, true!
I don't think anybody is questioning whether or not stacking more and more rotors is possible.
The real question is: what is the overall benefit of stacking six rotors as opposed to tuning a smaller engine with less rotors?
Mmm...there are some challenging turns in some of those pipes
And that goes back to the earlier argument of whether or not more is better. Hey, the guys down in PR keep breaking records with engines way smaller than this one pushing some serious hp

What standard they were not....after one spends a lot more $$$'s than the car was worth new...maybe.
Having owned a 10A RX-3 Coupe...I will tell you what was bloody awful from new.
Brakes...they were crude and faded after first stop, small Disc's front, small Drum rears (same rear shoes as a Mazda 1200,1300).
Suspension...pathetic....Rear leaf springs (thin) would sag after a few years use, the long tall rear shocks would also give out after a few years.
Handling, just did not exists, compared to cars from the 1990's.~
4 Speed Box...OK for a tall 4 speed, Nothing like todays 6.
10A Engine, neat small rotary, but gutless...would last 30K if you were lucky.
12A (B) were better reliability wise, but REAPS emissions took some fun away and HEAVY exhausts system.
Hood would wobble above 50 MPH.
GREAT to look at, but that is about all.

however the race cars must have been good from looking at the racing history of the rx3
but my god are they good to look at!
but who has a factory rx3 nowadays anyway......

Oh Yeah, in their time, particularly in the early days of Japan racing RX-3's were the kings of the tracks.
Chalk and Cheese to today.
I bet in New Zealand like OZ, there are RX-3 or converted 808's still running around.
10A RX-3 Coupe in Sunrise Red (code RH), was $2,875.00 brand new...the competition was the first gen Toyota Celica, guess which one won me...
