Un-tuned?

Anyway your just being technical to try and catch me out.
That's mean.

yes and even from a GSX 600 you can produce far more then 200hp from those too and that is in 600cc land. That is a engine you wrap you legs around and go. The bike weighs 345 lbs dry if I remember correctly.


Edit, btw AE86 Type R wtf is that????

hey halfracedrift jsut cuz i say that doesnt meen i dont liek them jsut im pointing out stupid mistakes they make, second of all i get **** liek that all the tiem from punk rock and other members so im jsut paying back the favor is that alright with you? or do i need a permission slip?

You have no business posting here. Leave.

This is a nice, short-and-sweet warning, because I don't feel like typing more right now (too much homework): Cut it out. You complain about how people treat you - fix it by not being an ass.

I definately like the use oif Ass here way to go Sage

And a Merry Christmas to you all!

A donkey could also be described as an ass.
Therefore you are both a posterior in some peoples opinions, and a donkey in others. Merry Christmas. Ass.

I think this is fairly conclusive.

Not really. The displacement/power argument is very misleading when it comes to comparing a rotory to a standard four-cycle piston engine.

A piston in a standard four-cycle engine fires every other revolution of the crankshaft. In a Wankel rotary, there is a combustion cycle for each turn of the output shaft.

Each crankshaft revolution uses half the capacity of a 4-stroke (the other cylinders are somewhere in the exhaust or compression stroke), whereas the full capacity of the Wankel is used every turn of the output shaft.

So a 1.3 wankel is consuming and burning fuel at roughly twice the rate a 2.0 liter four-stroke does. You can think of it as the rough equivalant of a "2.6" liter four-stroke.

The real benefits of a rotary is the small size, smooth power delivery and a fraction of moving parts compared to 4 cycle piston of simlar power output.

And rotary is undeniably cool...

True dat. That's part of the reason why the RX-8 will mostly likely be my next ride.

Did the 1980's RX7 savanna have rotary? It seems a bit advanced for the eighties...

Words of wisdom here... What would you do with, say, a 20B off a Mazda Cosmo (that'd be "2.0 liters" in your universe, when we all know you can't consider displacement the same way in a rotary) that produces either 260 or 280hp, depending on the model of the said Cosmo, and say, the 2.0l 4G63 found in earlier Mitsubishi Lancers, rated at 280 hp?

It's a moot point. You like what you like, they all have weak points, there's no point trying to see which one's best.

All RX-7s had rotaries, even before the 80s.

 

[Danny]

Cool. I wasn't even aware of Pre-70's RX7s

And punkrock, Mazda have come quite a long way with rotary since the cosmo. A 1.3 can achieve 200hp+ WITHOUT tuning. Try that with pistons. I am fully aware that someone will try and outsmart me. Bring it on!

(I'll probably regret that)

 

[MazKid]

Here's a list of all of Mazda's rotary cars that I can think of as of now:
Cosmo Sport 1967-1972(first rotary production car)
Luce Rotary(1968?-1973?)
R100(1970-1972)
R130(1970-1972 methinks)
RX-2(1971?-1974?)
RX-3(1972-1977)
RX-4(1973-1977)
RX-5/Cosmo(1975?-1978)
RX-7(1979-2002(worldwide))
Eunos Cosmo/929 Cosmo(1975?-1996?(different generations in there))
REPU(1973-1977 I think)
Parkway 26(RV thingy from the '70s)
Roadmaster(a Holden/Mazda sedan)
RX-8(including RX-Evolv and RX-01)
HR-X(Hydrogen Rotary concept from the '90s)
HR-X2(2nd test of above)
RX-500
787B
Star Mazda series cars
Many prototype race cars

And I'm sure I'm missing some, but I'm sick right now so not thinking to my fullest extent.

 

[humbo]

I'd go with rotor, because theoretically it is superior to piston engines since the rotor is always moving in the same direction while the pistons have to decelerate then accelerate over and over again as it moves up and down.

Except it's not a 1.3, so your point has no meaning.

 

[Boost Lee]

Oh but it is!

Technically

 

[Danny]

Er...yeah. What he said.

 

[Frustrated Palm]

I havent seen a rotary do a quarter mile in 4.4 seconds.

[EDIT] not that I dont like rotaries, as I like them alot. Just depends on the car.

What's your point?

My point is, if rotaries can produce more power, better, why arent they used in top fuel or whatever. Im sure there are a bunch of engineers who can pull it off, but why arent they?

[EDIT] btw, I love your avatar ...

 

[Boost Lee]

I have no idea... I do know there are guys pulling 6's with 13b's.

The Rotary is still a relatively new motor compared to the piston engine. Give it time...

 

[1.3L 13B REW]

correction.the 6 secs are from a 20b and abel ibarrera also went with the 20b

 

[Boost Lee]

There are more people in the world that run Rotary's other then Abel.

I see this turning into a one way conversation.. I'm going to the bar. Have fun

 

[Danny]

Stay here and have a pub arguement instead!
