Power to litre ratio? Totally irrelevant, other than for use as a marketing tool, in anything other than a racing series that dictates caps on displacement. A high hp/litre ratio in itself means little to the end user.
The other two ratios you mentioned have relevance to performance. My understanding that an LS1, is within 20 lbs of the 13B. Please correct me if I am wrong. What does a fully dressed 13B weigh including turbo hardware?
Size to power? If a 422ci LS1 can fit into the same space that was occupied by a 1.3 rotary, wouldnt that ratio tilt in the favour of the v8????
If rotary engines represented superior technology than the piston engine, please explain a couple of things to me:
a) why it is used by by only one manufacturer on only one of their vehicles (and why versions of Mazda's economy car and family sedan are faster than their so-called flagship sports car. equiped with a rotary.)
b) why do owners with functioning rotary engines go through the trouble and expense of swapping out their engines for a piston powered one (supra i6, LT1, LS1, sbc's etc), yet very few swap in out their piston engines for rotaries?

and last but not least, my favorite; the piston engine for automobiles, develop in the pre industrial revolution, ( 1769 to be exact), for use with steam power.. so that puts your technology inline with leather working and stone masonry as some of the few remaining 'technologies' from the 18th Century still around. No wonder you mullet heads love em, they ARE that simple..  |
