mega crazy rotary idea
iv had this idea but not sure if or how it would work.
get two twin rotor engines and make one quad rotor, but instead of lengthways like a 2cylinder to make a four cylinder, id do it like a scooby engine so it was two twins next to each other with a common plenum/intake, two turbos, and a common driveshaft down the guts.
( )-( ) << like that kinda.... if you understand.
now what im trying to work out, is if you can mirror the housings left to right, but have the rotors spin the same direction as each other???
any clues?
Ignoring why, it's not quite what you are thinking of but try a search along the lines of "Rolls-Royce cottage loaf" and also "H16".
ur right about being slightly off what i was thinking, but the general idea is there.
my main thought was firstly something different, as we all try for, but knowing what a quad rotor can achieve (insert mad mike and his quad rotor RX7) imagine that, times two...
next was to have an eight rotor engine that i could nickname the V8 rotary. just to piss rotor heads off!! lmao.. but seriously, its something on my to-do list is build one of these frankenstien engines.
*goes back to the day dream*......
go
pretty sure rotors cant spin the other way cause of the shape of the combustion area and angle of the intake and exhaust ports are designd to help spin the other way, so it would be just fighting each other.
another way to look at it, if PAC performance and Queen street racing havent done it, there a very good reason for that...most likely it cant be done
im sure there is a way it can be done but it means that it wont be symmetrical like im thinking of.
and im 99% sure that if one bank is a mirror of the other then it cant spin backwards, as you said due to the shapes internally., however peripheral ports might possibly change that concept, i think i need to do a little more research on the humble rotary.
go
you could well be right, but there has got to be some sort or force to keep it spining the one dirrection after the starter motor lets go, youtube some of the rotor videos, and look at some pics, the combsution area isnt semetrical, which i assume is to help with directing the combsution force
Wouldn't need to run backwards. Both could hit a single converter in the middle.
In saying that it would be a total waist of time and money as rotarys work of low resitance... Two rotarys spinning into one gear box would create quite high resistance.. Would be better off running them in a straight line.. Then again, just get a straight 12 engin.. Will work better. Rotarys are..... special.
Ill leave it at that
special like Im Speshhscal *drools* or special as in a league of their own?
the holden mechanic
mmmmmmmm 8 rotor lol.... do it! that would be making a friken insanely loud noise at revs haha
mmm, yes i can imagine the noise, kinda why im liking the idea of a twin quad rotor engine....
Special as in "Im Speshhscal *drools*" (There. Saves us saying the word "Retard").
I think you should try this... but only because I get a hard on over things blowing up.
nice one, perhaps ill finish my other projects first. and then have a look at a twin quad rotor engine.
I think you would have better luck applying the principles of a twin charged engine (Turbo and Blower), to merging a v8 with a rotary...
But I do maintain my stance on rotarys being shit
the holden mechanic
lol nah i meant 8 rotors in a row...
Thats a Lonnnnngggg bonnet... I like it >.><.< It would pretty much be a merc SLS gullwing with bonnet x 2
the holden mechanic
pretty sure the gearbox would end at the diff haha
Yeah might have to raise it so the excess engins and the box don't scrape on the ground xD

how on earth do you plan on joining the two driveshafts together? something like an old steam train?
Lucky they're strong engines.Originally Posted by boypocketsjr

this may seem like a strange analogy, if thats even the right word, but in my mind, i see an engine kinda like a battery. put them in series, (add the voltage) is like adding cylinders to make more horsepower? and running them in parallel, (doubling the amps) is like making the pistons and crank bigger, to make more torque?
hmmm, that kinda goes completley backwards as to why i would join two rotarys together..... i think ill do some more thinking into this...
as far as joining to quad rotors together lengthways, im sure it would fit into a commodore ute tray??
Not so simple. Like I mentioned before, there would be a considerable amount more friction. Big reason why extractors offer more KW on an 8 then they do on a 6

You could use a single gearbox mounted directly behind one engine like a normal setup, but with a custom bellhousing to let the two engines connect by a geardrive on the flywheels. this way you could turn one engine around so the front is now at the back so you would fit a flywheel where the balancer normally goes. You would need to make a lot of custom parts but it is do-able. You would run the motors in opposite directions

you could also get an apache gunship engine in your commo for about the same price
Rolling on 4 again :D
I know of a bloke in NSW, used to own Castelmaine Rod Shop. He shoehorned either a Rolls Royce Merlin engine, or an Allison, I can't remember... into a 50s chevy. ~5 years and hundreds of thousands of dollars in fabrication and adaptation to make it work. Ultimately he got it going and it gets taken to air shows and run down the strip sometimes.you could also get an apache gunship engine in your commo for about the same price
EDIT: Here it is YouTube - Merlin V12 Powered 55 Chevy
