RE: Can we please act like adults
I read throught this one last night, and figured I would come back today and see if mabey it made a lick of sense.
I still have no clue what this tread is even about. Someone please make up some Cliffs Notes for something.

ummm...there is a replacement for displacement...and that is called volumetric efficiency....but its all your own opinion man, i for one would chose engineering over a big 8.0....

Volumetric efficiency in internal combustion engine design refers to the efficiency with which the engine can move the charge into and out of the cylinders. More correctly, volumetric efficiency is a ratio (or percentage) of what volume of fuel and air actually enters the cylinder during induction to the actual capacity of the cylinder under static conditions. Therefore, those engines that can create higher induction manifold pressures - above ambient - will have efficiencies greater than 100%. Volumetric efficiencies can be improved in a number of ways, but most notably the size of the valve openings compared to the volume of the cylinder and streamlining the ports. Engines with higher volumetric efficiency will generally be able to run at higher RPM, and thus power, settings as they will lose less power to moving air in and out of the engine.
Large engines are not allways lacking engineering, the older big engines used in trucks, rigs and such back in the 20's, 30's, 40's, 50's, and 60's were largely in-efficient but smaller I4's were also in the same timeframe. Also higher reving, and more hp per liter has it's draw backs too. More stress on the reciprocating assembly is a main one and that is why in the import I4 world you hear of tons more rod berrings going bad. Reving also is not the whole story while it does somewhat indicate the purpose of any certain engine it still is not a tell all and be all of engine design, abilities, and/or reliability. So what you say in many ways is simply not true, there are big displacement engines out now in form of crate engines fully backed by automakers with warrenties pushing absolute stupid amounts of power, on pump gas(talking in the 500 to 700+hp range) with just as much tq if not more. All while being able to rev past 6500rpm.

I know that this not 69 Muscle but lets face it new is better then old.

Take the fastest, most built I4 or I6/V6 and compare to this
I watch this **** 4 times a year and anyone that wants to say V8's do not reign king of the crop needs to put forth the effort to build a I4/6 cyl to do better than that ^

RE: Can we please act like adults
you couldnt build a i4 to beat a built v8, unless you did a w8 or some **** like that....
i have nothing against muscle, as a matter of fact i hope to one day have a charger project, but it is more impresive to build a i4 that runs 8secs than a v8...
