The May issue of Sport Compact just showed up and there is an interesting article on pg 14 about the renesis, this guys thoughts about the future RX7 and a 16B eight port direct injection engine, displacement of the rotary, etc... He brings up the argument about how the 13B is 2.6 liters, 20B is 3.9 liters, Mazda is wrong, etc. Its worth checking out.

Damn, have not gotten mine yet. https://www.nopistons.com/forums/pub...1047683358.gif

haha no it's not

I have yet to hear a good explaination of why it would be 2.6, not 1.3.

Do you think mazda (The people who designed the frickin engine) has not debated this? Do you think that they felt smaller is better and 2.6 would be way to much for a rotary. So if you designed the engine i say you should know how much it displaces. So if you arent mazda. . .shut up

im mazda....

Well actually I think they did think about it... and doesn't 100bhp from 1.3 liters sound a LOT more impressive than 100bhp from 2.6 liters? I sure think so. Now I haven't studied the subject to any great extent, but I know that the rotary's combustion isn't all that efficient so how could they be getting all the horsepower they do from such a small displacement? For me the 1.3 liter thing just doesn't add up when compared to it's piston counterpart. But, then again I could always be wrong.



And you by the way are so close minded you sound like a migrant from rx7 forum. At least think about a new idea before automatically discounting it you feeble minded peon.

i just read it last night. i agree it is 2.6L when it is running but when its stopped its 1.3L https://www.nopistons.com/forums/pub...#>/biggrin.png

its all the the way you rate it. a rotary will fire its rated displacement every 360 degrees of output shaft rotation. a piston engine will fire half its rated displacement every 360 degrees of output shaft rotation. so if you take the full piston engine displacement the rotary is twice as large. so its all in how you look at it, if the 13b is 1.3l than a 4.6mustang is 2.3l....
