The Mazda quad rotor 787b, this thing was all conquering, so much so they couldn't beat it so they banned it.......:bow:

Reminds me of an old rx4 coupe i had with a 13b in it and the exhaust came off in town early one morning. No exhaust rotary sounded mighty loud bouncing off the city buildings at high revs - not like this one though.

Had a little red light on this console on the ceiling that would flash at red line and start this beeping noise. I think they had no way to limit the revs and so it could just rev till they flew apart - or something catastrophic anyway.

Had never really noticed the little console on the ceiling until it started flashing and beeping and first time thought, wtf was that?. Good little car - think "mini-mustang" was the Jap styling idea for the 2 door - looked like a clapped out 180b to me but it was a good little Alfa killer. You had to wind it up from low revs though, this one never seemed very responsive if you just tromped it from mid-range - don't know if that was typical of the species.

Bloke i bought it off had this flash Valiant hemi he said he'd spent about $10k on the engine (20 something years ago) - told me he raced some peripheral ported 13b equipped little rx2 and, as he so eloquenty put it, the thing was so quick off the mark "it sucked his headlights out". Good expression that.

Pretty awesome those little rotaries when hotted up and with that distinctive sound.

I could listen to that all day :bow:

Sounds like a modern F1 engine.

(I've lived the dream through my PS2 aswell !!)

Anyone taking bets as to the redline of that? 25,000rpm?

Some people may be suprised that rotaries dont nececarily rev to higher levels than piston engines of similar tune. Considering that a 13B is actually a 1.3 litre engine, a 1.3 litre 4 cylinder punching out the same power as a 13B would have to rev into the stratosphere.

With stock port anything over about 7500rpm and the power drops off dramatically even though you can rev them past that (say to 9000 or so) you will just go slower.

Even large bridge ports will drop off over 8500. The Bridgey in my R100 had 250 hp at 8500 rpm but really died after that.

I had a quote for a "full race" injected peripheral port 13B with 330hp for $5500 (I am talking 9 years ago here) for just the bare engine with out anything on it (injection, exhaust etc etc) and the guy said it would pull 13000 rpm every race meeting for a year before needing a freshen up.

I may be wrong but I cant see the 26B revivng any more that a couple more thousand rpm than that (maybe to 15000 rpm?) as it is essentially 2 13B peripheral port engines joined together.

As a matter of interest at last weeks Jamboree 17 at Willowbank, Queens Street racing had their 26B 4 rotor drag car competing. Sounded even meaner the one posted above. Lovely sounding engine.
info on the car is here (http://www.mazdarotary.net/queenstbmw.htm)

I remember a few years ago there was a sound recording posted somewhere on this site of a car running around a track, on maybe a test day.

Sounded like Leman style car, but was recorded in surround sound.... was simply awesome with the sound right up

I seriously hate rice burners but man that sure sounds sweet to the ears.

Bet his has awesome acceleration.

My rx7 never ran like that, that's why im going with an ls1, rotary's make plenty of power and stuff but i would hate to have to be replacing apex seals between every run. Give me a dependable v8 anyday.

Are you kidding?

Rotaries are solid as if you want to talk in terms of reliability.

back when Alan Moffat was driving his early rx7 in the Australian touring car championship with the peripheral ported 12A he only used two engines for the whole year of racing, one qualifying engine and one race engine. At the same time the V8 teams were chewing through at least 5 engines per year.

Too many people hang on to the early 10A and 12A twin dizzy engines lack of reliability. These people drag out the old "fragile rotary" chestnut every time they try to make them selves feel good about their decision to own a V8.

by the time the RX4 and RX5 were released rotaries were lasting just as long if not longer than piston engines.

less moving parts = less wear and tear.

Alot of engine failures in rotaries can be linked to the drivers lack of knowledge of them. Some people think that rotaries can just rev and rev forever. While they can be built to rev very high and still be reliable they cant rev to levels along way past what piston engines can unless they are built specially to handle it.

meanest sounding race car...?

i had the opportunity today to listen to one AWESOME
race car

Stan Jones' Maybach
its a legend and today at Calder
was being thrown around the circuit by John Shepherd
(him of HDT fame)

it comes with stub exhausts with poppets of flame
on the overrun....
imho..one of the meanest sounding race cars is this-

and contrast it with one R Kelly's ride today

the Maybach sounded better :)

Sounds good, but this sounds better.

A 1.5 litre supercharged V16 making around 600 hp and it was made around 1951.

The BRM clips are awesome, someone ran a "competition" thread here a year or so ago asking people to guess what it was......

Spent weeks surfing the web with that clip looping through my headphones - magic!
