RICE RACING

I can't help you if you don't understand how every internal combustion engine principle works. You need to re read over my posts.

So people don't get confused: The 13B measuring in the 4 stroke time scale is a 2.616lt motor, that is all most people like on this site would want to know "how does it compare to my Datsun" ? < that is your answer. The rotary engine as a racing motor for its size is the most durable and long lasting for its power to size relationship... proven fact over many racing classes. The reason for this is the the secret in how slow the rotor turns to do its cycle and how much area there is for various load bearing parts be they bearings or seals or combustion faces they are a super reliable racing engine and no other motor for its capacity can match it in power output or use of stock parts to obtain these various levels of power be it in drag racing or circuit. Cost & simplicity wise you will never ever beat a 13B engine compared to any other 2.6lt 4 stroke engine. *remember the time scale*

What people forget is this basic fact and you only need to look at the spark plug (assuming non wasted spark!) < key here is wasted lol. now a spark plug only fires when it going to produce a power pulse. 2 stroke this happens at 1 rev (360deg) 4 stroke this happens at 2 rev (720deg) Wankel this happens at 1rev,2rev,3rev! (360deg, 720deg, 1080deg!) and corresponding displacement values are 1308cc, 2616cc, and 3924cc!) Now if you are objective you can see that Mazda is right in claiming 1308cc for its 13B, but they would need to call it a two stroke so newbies had some idea of how to compare it in a time scale to displacement as ALL people and regulators want to know WTF they are looking at so they can compare it to other more well known engine principles. The simple fact is though sure it describes one power pulse but it does not describe how much it aspirates as a comparison to other engine types. Thus you can call/compare it to the two well known and understood engine combustion cycles as outlined below 13B Wankel is like a: 1308cc two stroke 2616cc four stroke but it really is a 3924cc Wankel ^ The problem Mazda face is that they and others mind you decided to go away from the basic fact that engine cycles and "total" displacement are tied together, so since technically the lower capacity fits the same definition of one power pulse per event they went for the lower figure and no joe shmo actually understood that it took 1080deg for a Wankel to do what it needs to do! thus other basics cause confusion like why and how rotaries technically don't need as much ignition timing advance for the same revs as a piston motor cause it take 1/3rd longer for things (combustion!) to happen ! Its really all is very straight forward.

Simple. 1. The crank degree's are directly linked to the rotor face position, and thus are linked to the cycle position as shown graphically in photos and also in the above post. ALL ENGINES cycles are defined by the output shaft crank angle and firing events or power pulses. 2. In one rotation of the output shaft, 654cc is displaced per rotor in a 13B engine. <, So 1308cc per 360 degree's and you will find also there are two power pulses or ignition events to match to back this up

For the benefit of others, have a look over this it puts my pictures along with the cycle description for a 2 rotor For anyone that cares to learn more about this topic and even how much it confuses rotary people you can go look over and read the main thread I started on it, this subject creates allot of reaction and confusion mostly amongst people with no formal education in mechanical engineering. The ones who have passed thermodynamics though get it very easily http://www.ausrotary.com/viewtopic.php?f=3...amp;hilit=3.9lt Peace out, and remember to check the qualifications of the people you choose to worship on your fav forum before jumping onto the bandwagon Oh and EVERY operating cycle is described by its direct mechanical linkage to the output shaft! be it Wankel, two stroke or 4 stroke! *direct mechanical linkage* the definition is simple one chamber to repeat its power pulse, this defines ALL engines of internal combustion type. The only thing Gaz is kinda right on is the capacity, the lack of knowledge of the Wankel cycle is the only travesty allowed over so many years. 1080 degrees is it. So in summary if you want to compare it to the common 4 stroke! (remember its all equivalence based) then you only look at 720 degrees and how much it has aspirated, then you will find the classic 2.6lt comparison *Apples to Apples* in volumetric terms. < But does nothing to describe actually how the Wankel works. You need to look over the info I provide and also maybe take a basic course in operation of engines to fully get it if you are struggling.

Far from it, its me knowing you are an idiot for your delusional ranting baseless posts on a topic you obviously know very little about

For post whoring and having no idea about mechanical engineering nor thermodynamics? I would agree 100% If you want to know about how engines work I will tell you right now this Gaz is an oxygen thief with limited idea and no formal qualifications to comment, nothing more. Listen to him if you are a sad deluded fool, if on the other hand you want to know how ALL engines work you must read and then re read my simple post, look at the pictures............ even a 5th grader could get it Peace out Skyline people, I hope all of you are not as uneducated as what I have seen from some in this thread

Gary, When was the last time you have had sex with a female?

No worries glad to help.

Neither do we, when there is just pure ignorance and selective memory towards what we like you can see the reaction. Facts are, the rotary is flawed, but it is also great as a racing engine in any form... which is one of the things it is exceptional at. < and when combined as a total design concept (car and engine) as in the FD3S it is basically unbeatable even against the worlds best efforts

Also remember, The "touring cars" FAILED against the real sports cars lapped multiple times, Any clown could Group A a heap of turd into a fast car (those same worthless buckets Commodore, Datsun, Ford etc) basically finished nowhere while the real boys went and fought for the title of who actually makes the best sports car in the world. The title belongs to the rotary engine and the FD3S, end of story. Not bad for an engine that sucks hey Not much has changed today, sure you can go spend $500,000 and make a Commodore go o.k. does it mean its a Commodore though or is it like the Datsun a failure in its original designed form? You cant fault the rotary engine, its a purist sports car that put Japan on the map! and blew all the pretenders no matter what thier reputation or cars they could muster clean off it !

^ Stick to what you know, rotaries is not it Remember you cant google your way to knowledge and forums are not the place where history is written datsun failed in the real car world and premier race along with every other much more capable sports car maker at the hands of the rotary engine ............ so dont forget the respect next time people go on in worthless cyberspace about how shit rotaries are Challenge is there to ANY road registered Datsun too, if your man enough you can go to my site and get my details and I shall provide you with a little history lesson out on the track

No its a little bit of wishful thinking getting in the way of history and facts When the FD3S was available Group A was in its death throws! so for Mazda to go make a Group A special tweak version would have been stupid as they would miss out on the world wide category prime years in a nut shell (wasted money for what, a series that was in decline world wide). There would have been absolutely no issue running 550bhp region as Mazda did this in 1984! with their Group C sports prototypes in Japan running 1000km endurance races against Porrsche 956's and so on, these same basic engines were given to Racing Beat and slotted into a S4 RX7 which set a land speed record of 238mph in 1985 so no problem with power or durability as the history states easily. The FD3S's and Mazda Japans main focus was on showing the potential of the car in its basic form and it dominated ALL comers, even winning the production class at Bathurst in 1999 against GTR, Ferrari, Porsche and many other losers ultimately I think you boys need to maybe show a little respect towards the Rotary and the RX7 even if you dont like the way it sounds or understand how it works. As a proven racing car nothing comes close to it, and I dont need to remind you all that the only Japanesse winner of LeMans 24Hr was rotary powered

Nice thread Displacement is here, its written in Layman terms so no one here should have any difficulty I decided to put this together for the new players who struggle with understanding what a wankel cycle is about and also the true capacity of the engine, a picture tells a thousands words, so I cut up a rotor and a shaft and marked them taking a photo at every 90 degree's of main shaft rotation, following a chamber from firing to firing or one full Wankel Combustion Cycle. 0 degree's TDC No1 chamber firing 90 degree's 180 degree's 270 degree's 360 degree's (one revolution of crank) 450 degree's 540 degree's 630 degree's 720 degree's (two revolutions of crank) 810 degree's 900 degree's 990 degree's 1080 degree's Wankel Cycle is complete ! (after 3 full revolutions of the crank shaft) No1 chamber firing again From the above you can see each individual separate chamber (3 per rotor) only fires after 1080 crank shaft degree's has elapsed,, this is why the Wankel is so different to ANY other type of engine, 2 strokes fire each individual chamber once every 360 degree's and 4 strokes fire every individual chamber every 720 degree's. If you look at a 13B with its 654cc per Individual chamber capacity (thus 1308cc) you can see it aspirates this ONCE every single revolution thus you can compare the 13B to a 2 stroke if you must do so on an equivalence basis (but remember you are not counting the other 2/3rd's of the combustion faces! Now if you compare it to the much more common 4 stroke engine you can see that 2 faces ONLY are being counted in the engine and thus it has aspirated a total of 2616cc over 720 degree's of crank shaft rotation....... nice little bit of info there but it still misses a whole 1/3rd of the engine! Finally the ONLY TRUE way to look at a Wankel Rotary is to view it in its own cycle! (and not comparing it to something that it is NOT!) this is only over 1080 degree's of crank shaft rotation, where ALL of the working faces can be accounted for (just as when you do a compression test to see if the poor little donk is healthy or not) For it is only when the entire engine has complete one full cycle of work can it thus be rated, be that as functional or in its true capacity sense. You will then see that the humble 13B is indeed 654cc x 3 working faces x number of rotors ! = 3924cc. Equivalence capacity to time scale (revolutions) for 13B engine, has one power pulse per 360 degree's per rotor 1308cc 360degree's (2 stroke) 2616cc 720 degree's (4 stroke) 3924cc 1080 degree's (Wankel Rotary) So far as rotaries sucking? Mazda 4 Porsche 0 in the only race that actually proved who made the best road cars (not dressed up fake group A $500,000 cars !) I don't remember ever seeing a Datsun do anything in any of those 12hr production car races nor Porsche, nor Ferrari, nor Lotus ............... Happy to take on any one of you ladies and your cars at Wakefield Park in any road registered GTR and hand you a lesson is respect and history

I have itchy balls

Does anyone know where I can buy good quality roof canards before this track day?
