Short induction paths...loss of power? - 20/12/2009 14:31
I would like to ask a reasonably direct question if I may.
On the 20v n/a and 16v n/a will a short induction path and removal of the resonator box actually loose power though the lower end of the RPM band?
And if so, will some one care to explain why?
Any engien wants nice cool air with a nice smooth entry path. So if you provide a 20v or 16v with a reliantly short induction path with a cold air feed (specifically the 16v on this occasion) why is it people say they loose power?
The only thing I can thing of is with a longer induction path and a larger volume of air between the filter and throttle body there is a (little) volume of already filtered air before the car starts having to "pull" air though the filter, At high RPM I can see why the shorter the path the better...
Is this all gibberish? Will some one with more technical knowledge with fluid dynamics care to comment?
Second question of the day
Exhaust systems, On a N/A car I understand there is a need for back pressure, something about exhaust gas scavenging with some fairly complex calculations with gas exit speeds, and volumes
With a turbo however you want the gassed getting away from the compressor wheel as quick as possible? so surly we should all be fitting massive down pipes and 4 inch systems for power gains....some one mentioned to me once over spool of the turbo as being one problem.
Is it not as simple as fast gas in, faster gas out?
