Why Do Rotaries Suck?

Oh dear. The initial conclusion to this thread was dicided a while ago. It simply came down to an 'opinion' on what constitutes a rotaries combustion cycle. If you beleive that a a rotoaries combustion cycle is one combustion from each rotor and turning the essentric shaft one full turn then it is a 1.3L (my opinion) or if you beleive that the rotaries cycle is comprised of 3 combustion cycles from each rotor and turning the essentric shaft 3 full times then you beleive it is a 3.9L. In my hypothesis and conclusion I went into alot more detail including strokes, angles and capacities etc. Not going to re-state. Its just new people wanting to re-argue said points and stir the fieces back up again.

Whilst we share the same opinion with regards to rotary capacity...I reckon digging up the thread from a few weeks ago is somewhat hypocritical of what you're saying at the end there :P

Happy Birthday rotary thread. Today you turn 50 and we salute. You have brought us good times and bad times; winners and losers; ragers and dedicated followers. You have taught us the ways of Wankel. May your life be free of piston engine comparison. May your spirit burn on like the oil in a rotor combustion chamber. May your mystery and enigma continue to dazzle the minds of mere mortals.

Love always,

Birds.

f**k what have you all managed 50 pages only talking about chicken cookers??

i dont mind rotors . used in the right aplacations they are fairly good . kinda like a small light 125cc two stroke bike can really hold its own in the right circumstances

the main thing wrong with rotors is all the idiots that think they are the be all and end all of everything. rb30s are getting the same way . yeah what RIPS has done is f**kin off the hook and i love it . its just sad when you see numb nuts out the drags with blah blah 300+kw rb30 in a laurel that is slammed and has nearly 45degrees of camber on the back wheels that goes home on the trailer but managed a 16 sec next week they all talking bout this "beast" that ate all the gtr's

sold my skyline to get back in a rotor *puts flame suit one* i missed my capella 13b monster bridge and 3rd gear donuts too much, i am not biased i love all forms of cars, i had great times in my skyline but the way the power is delivered in a rotor is a great feeling

not entirely true bozodos. You only need to premix your fuel if you have taken the oil metering pump off the engine.

And any rotary is no different to a GTR with regards to servicing. Change the oil and filter at regularly intervals. When you change the plugs use a quality plug and you will be right. I dont even warm up my rotor, nor the RB26 that sits next to it in the garage. We simply drive both cars sensibly till they are at temp and drive them appropriately before we switch them off.

A lot of people will argue that seals are an issue on rotaries..... sure they may well be, but the number of engines i pulled down when i worked at Advan that had spun bearings puts RB26's well on par with the rotary engine when it comes to failures :)

    • Opened up the cluster to inspect the gauge itself for signs of damage and it looks good. Got curious since that needle doesn't go back to a "neutral" position by itself (it stays in the same position when ignition is off. so I manually moved it to 1/2. Connected it back, turned on the ignition and the needle started moving up! Not sure what's up with that but before that the needle was way down below empty like fully south west. There's always a chance that the needle moved slightly the first time I tried and I didn't notice because of how slowly it moves and how far it was from the markings. I don't know if the current needle position is accurate so I'll fill it up and see where that brings it. I guess I'll try to adjust it manually if it doesn't get to F. Looks like the needle position is relative and not absolute? Thanks all for your help and patience!
    • You're confusing two different responders and more than one issue. The stock Neo ECU boost sensor is used by the ECU for protection purposes. It is essentially only an overboost sensor. It is not used for determining engine load for fuelling or ignition purposes. That task falls solely to the AFM. Any aftermarket ECU that either has an onboard MAP sensor or a plug in one, will use the MAP sensor as the primary load sensor. Or I should perhaps say "can", rather than "will", because some of them have the option of using other primary load sensors. That MAP sensor is not for the same function as the stock Neo boost sensor. The reason I recommended against a plug and play ECU is that they are intended to run a particular engine and usually in the car that the particular engine came in. So, if you have a transplanted engine in a different car, with some parts of the original missing (such as the boost sensor, for example) and therefore likely non-standardness of the loom and its insertion into the car's loom, then it is very likely that you will run into the same problems with needing to fix up wiring to make it work that you would with the stock ECU. And, if doing so for the stock ECU is enough of an obstacle that you start considering a standalone plugin as a solution, it should become clear that the plugin is quite possibly not the solution you'd hope it to be. It would just lead to more of the same type of problem solving work to get it going. In the above paragraph and in my earlier post, the lack of the boost sensor is not critical. It was just used as an example of something that we knew you did not have right, such that the stock ECU would not work. I took that as an indicator of a reasonable probability that there were other related problems hiding there.
    • I can think of two places in my city of <1.5million population that specialise in automotive instrument repairs.Unless you're out in the wilds of Quebec, you have 3 major Canadian and 3 major US cities within the same distance as the single nearest city to mine. Surely there is somewhere you could send it.
    • I never cared for twins but whenever these conversations came up, I always presumed the higher number represented a larger turbo. Learn something new everyday. 
    • Interesting, I've never seen a failure like that before but with the age of these cars and the general questionable-ness of all kinds of parts these days you can't rule anything out I suppose. Boost leak testing the boost control system would've revealed this though.
