Hey pplz, Im from Melbourne in Australia, i drive a 95 Vti civic sedan :P
Currently undergonig some mods, she will hopefully be decked out nicley in a few months.
I plan on changing my engine to a b18c dohc. however.. If anyone has done this, and knows of a better alternative..
Please let me know.. (the cars auto aswell!) :P
Shes a sleeper atm, hopefully not for long!

 

the B18c is hard as hell to beat. i have one, and everytime i walk out to my car, i smile because i get to drive it.

 

*sniff - How romantic

 

hey, youll understand someday

 

In internal combustion engine design, volumetric efficiency refers to the efficiency with which the engine can move the charge into and out of the cylinders. It is a function of a number of features, but most notably the size of the valve openings compared to the volume of the cylinder. 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.

There are several "standard" ways to improve volumetric efficiency. The most common is to use a larger number of valves, which cover a greater area of the cylinder head. Automobile engines typically have 4 valves per cylinder today for this reason. Many "high performance" cars in the 1970s used carefully arranged air intakes and "tuned" exhaust systems to "push" air into and out of the cylinders due to airflow over the engine. A more modern technique, variable valve timing, attempts to address changes in volumetric efficiency with changes in RPM of the engine -- at higher RPM the engine needs more time of a single cycle to move the charge out of the engine.



Thanks Heaps dude.. Now i really can't wait to get it!

 

wheres that from? not a bad article, except it doesnt actually say what volumetric efficiency is. and that is: the amount of air displaced per cycle of the engine as compared to its actual displacement usually expressed in percentages.

 

Yeah I can't wait. Hopefully I'll have my swap in by the end of the summer. But for now, I gotta keep saving.

 

yeah, ive been there. it sucks, but its worth it.
