Do I really need this resonator box?

[Nick1994]

After driving it the past couple days, I can't notice any difference in sound or power, and I drive this car hard. Pretty happy that I saved about $80.

Thanks for the help guys.

I assume you are referring to the intake version of scavenging. Top Fuelers use this I think to actually pull air out of the headers.....much like an exhaust fan in a warehouse is 'better' than a regular blowing fan.

Also, two-strokes can tune the powerband by changing the expansion chamber so they can ride the fat part of the powerband (or the highest).


It is still kind of new tech-like twenty years old as n the early nineties they used alot of regular round air filters which did nothing to 'pressurize' the intake charge. Although, I think Japan has been at it for awhile since they were making small fours and us Americans were putting around in big, lazy V-8s.


Thanks! I wasn't trying to be overly techy, I just copied a couple of paragraphs from my college notes. But yeah it's kind of related to exhaust scavenging - google helmholtz resonance

Without going into specifics, every aspect of air and fuel flow through a blown-fuel engine is analyzed extensively.
