Integra Resonator Removal

wheels?

Yeah of course - was not making this sound before I removed resonator.
Its not so much a vibration FEELING - I cant feel it.

Its just some thing vibrating making a loud noise due to the increased induction sound.

probably just vibration from the extra noise lol, that's why it had a resonator

[l3vnd1]

hehehe yeah thoughts so - wanted to know if anyone else had experienced it.

Its sorta like a distinct audible shift signal. lol

funny enough i removed my resonator from my DC2R tonight and i could hear and feel a difference. the induction noise is a lot louder and when you accelerate the air rushing into the motor at high revs resonates and the floor vibrates. It feels like a racing car. Could not feel a power difference sadly

As to the filtration side of things. Oem will filter out more with less air flow. Where as k&n will filter less and have better air flow. Think about it to filter out more the material the air is flowing through has to have thicker fibres hence less air flow. It all makes sense if you put it in that matter

yeah it makes sense like that -

but thats not what K&N claim...

No, K&N claims that an engine will run fine with 90% filtration efficiency when tested with test dust. http://knfilters.com/faq.htm#23

Paper filters usually reach 99% or higher. K&N filters have a cumulative efficiency of 96-99%, which means it starts at the low end of 96% and works its way up to 99% as the filter gets loaded with dirt. http://knfilters.com/efficiency_testing.htm

i was doing some reading and i found a book all about hondas. Its called "How to build HONDA horsepower with dyno-verified results". There was this interesting test on air intakes that i would like to share. So the following information is taken out if this book.

According to the book, CAI (cold air intake) provides better low down torque as compared to the SRI ( short ram intake). The CAI provides better HP and TQ all the way to VTEC point, where it starts to be the same as using the stock intake (as shown in the dyno test in the book). Whereas the SRI shows HP and TQ being the same as the stock intake before the VTEC point and it increases HP and TQ after the VTEC point.

The reason given is because the long piping of the CAI acts as a hinderance at higher RPMs while the short piping of the SRI creates a "ram" effect due to the shorted piping. But do not forget that SRI have a problem with heat soak. So the best intake system will be something like the Gruppe M's intake for the DC5R as it draws air from above the bonnet. Or the Iceman Comptech intake for the DC2R.

Of course, i'm not saying that this book is the bible and everyone should follow it. But its just my 2c worth of info for guys out there. I am sure not everyone will agree on this.

If thats true - how do you explain the 'flat spot' in the Injen CAI dyno sheet?
