hi,

Have a H22a 4th Gen Prelude. I have searched read everypost that popped up (11 threads)

I wanna drop a K&N stock filter (no CAI due to Hydrolock issues) and want to remove the resonator, but i am getting turned off coz dont wanna loose low end power for minimal high end gains !! These Questions are still unanswered :

Everything I have read has suggested that removing the resonator will cause a drop in low end performance and will not improve top end performance. The resonator looks restrictive, but it apparently does have a function.

I read somewhere recently that it is better to keep a component of the resonator and still use it, but with a slight modification. This makes for more low-mid end power, as well as more free flowing. I either read it here or on S-H.com. Thougth this might be insightful, peace.

 

no one knows wierd

 

I think I recall a dyno result granted 3 more horse power or something.

Just get an Ebay ram intake and cone filter and call it aday, if you wanted you could put an air box around it to draw cooler air up from the fender

 

I took out the intake resonator when I was in the process of installing the AEM V2 and I didn't feel anything but gain in the entire powerband

Tell me, how exactly does an extra HP or two feel ? im kinda curious.

Just remove the resonator. Or better yet, dont even touch anything and just put the K&N in there. If you are so worried about it then leave it in.

 

no you don't lose power from taking out the resonator at any RPM. It's ONLY function is to keep the noise levels down.

Taking out the VTEC intake butterflies will give you less HP at low RPM's but those are a different thing and they are in the intake mani, right before the air enters the combustion chambers.

It's to prevent sucking water into the engine too.

Based on the facts, I would say that overall you would lose a little bottomend and gain a little in the top end. Nothing noticeable. There is a part similar to the butterflies in the intake manifold (metal IM) in the reasonator too. That's what that little vacuum box is connected to the body of the car near the battery.

Oh, butt-dynoes don't work.

 

when I removed my resonator the biggest difference was in sound - sounded close to a shrot ram intake. I didn't notice any loss of power, but I did notice better throttle response, which makes sense since now the air just went into the filter, as opposed to through all those tubes that make up the resonator. It helped a bit in blipping the throttle when rev matching.

Thats what i thought but cant get a definitive answer !!

 

Because no one has dynoed a before/after with just removing the resonantor. And besides, the dyno numbers might be a little skewed because there is little to no air flow on a dyno.

Resonator's are there for sound attenuation (quieting the engine noise down) and to draw in slightly more ambient temps (which is horse pucky as the intake charge temp is basically the same for a cold air intake versus a short ram), that's it basically. They are not "designed" to give you more oomph anywhere.
