in march's Sports Compact Car magazine, they got this article on FD's.



my question is on a specific sentence that appears in the 3rd paragraph (for those of you that have the mag)



taken verbatim:



"The car's twin sequential 13B churned out 255hp from the same 2.6 liters (or 1.3 if you prefer convention over logic) that made 135hp in the first generation car."



my question is, what da hell is the writer talkin about 2.6 liter or 1.3 liters if you prefer convention over logic??



is he saying that the car is really 2.6 liters? maybe i missed a memo but i thought the displacement on rx7's was 1298cc (or thereabouts, too much drinking lately, memory gone to ****)



in a related note, on the last page the mag features this crazy SUPER stretch limo seven, looks crazy. i'll try to find a pic.

the 1.3L rotary makes as much power as a 2.6L piston engine.... that is what they mean

thats a retarded conversion. its like saying a space rocket makes as much power as a 8million liter engine.

the piston lovers are always trying to look for a way to put the rotary in a higher class, because liter to liter it is definately gonna win...

I think the conversion comes from comparing CFM's of displacement between the rotary and piston...to put them on equal terms perhaps?



Or someway forming a relationship between the cyclical motion of the rotary to that of the more linear motion of a piston...



I have a few Euro mag reviews of the TurboII and they are all listed as 2.6L as well...

Many European sources seem to say that it's 2.6 liters. Or at least it seems that way to me.

if you compare volume of firing chambers per rotation the 13b rotary will fire its full 1308cc's, while a piston engine will fire half of its displacement.

I think that the mag. was referring to how the rotary is class in races. They measure one rotors displacment on a single face, times it by two, for two rotors and then times two. This is to put the rotary in a more equal class with pistons. Because they know that a rotary will kill pistons any day all day long. :twisted:
