i was using my stock piping along with a blitz filter, so today i finally got round to fitting my intake pipe and i'm using the blitz SuS filter with it, but now i cant hear the secondaries cut in at 6000rpm any more. Before it was clearly audible at 6k rpm but now theres no extra noise or that little kick i used to feel. the car doesnt seem down on power above 6k rpm, has anyone else noticed this after fitting intake pipes???

 

i felt the same thing, i had a K&N on stock piping and secondaries where extremely loud, then i relaced it with the AEM CAi and i cant hardly hear vtec. some people said it was cause the filter is farther away but i dont really know

 

i'm using an injen short ram...i can clearly hear vtec at 4400 and secondaries opening up at 5800...

 

i got an AEM cai and it is ******* louder than exhaust when 4400 comes around then even louder when the 2ndaries open up... owned

 

Hey sorry if I'm bring back the dead but I think I'm experiencing the same thing on an H22A4 5th gen Prelude. I put in a AEM CAI and I can't distinctly hear my secondary butterfiles.

 

I have an Injen short ram and CAI extention. VTEC is way louder with the short ram than with the CIA installed.

 

i didnt know that the H22A had dual runner manifold...anywho...i barely remember posting this thread but i do know that after i reset the ECu again, and took the car out i can now clearly hear the secondaries...and theyre even louder than they were previous....it is possible that the butterfly valve(s) may get stuck, but its unlikely it would be all four, but if 1 or 2 got stuck it would significantly deaden the noise at 5800rpm

 

I hear the definite change in pitch when the secondaries kick. I have only an AEM CAI in my GSR.

 

I don't think you understand how vtec works. It is the secondaries that open at 4400 and <U>you can not hear vtec</U> !!

 

sounds like you've got the wrong info buddy. 4400 is not secondaries.

 

Vtec at 4400 or so depending on conditions and secondaries around 5800. You can hear vtec engage at times. You will not hear it in the engine though. With a straight through exhaust you will hear a pop when vtec engages sometimes. The first time I ever "heard" vtec was when importbuilders had a turbo civic on the dyno. It's vtec was malfunctioning. You could actually hear it come on and off.

I can hear it when I roll on the throttle so that vtec kicks in above 5k.

You are right. I was in a hurry last time I was here, thinking one thing typing another. Sorry, I do not like to give bad info. Should have read it before posting. Here is what I meant to say.

You can not hear V-TEC. If you can truly hear your V-TEC you have way better hearing (and quieter exhaust) than most or there is something wrong. Many people think it is the V-TEC that they hear when it is actually the secondary runners of the intake that open at 5800 while V-TEC is actually engaged somewhere around 4400.

 

I should have taken video tape of the civic with the b18c, but I will not argue this.

BTW, vtec only engages at 4400 under WOT, assuming you are going over 25 and have sufficient oil pressure. Under less than WOT it may engage higher.

 

you are still WRONG I can clearly hear vtec engage in my car with a short ram intake at 4400rpm, the secondaries are now louder, but i have had vtec cars before with stock piping and its also clearly audible at 4400rpm or 5500rpm (civics). I think you have a bit of a nerve coming in here after 6 posts and speculating about what you think people believe and getting it completely wrong

Thousands of members on this board will disagree with you when you say there must be something wrong if you can hear your vtec engage!! Do you even have a vtec car?????

BTW its VTEC not V-TEC

I don't hear anything until vtec hits at 5800 rpm. It's loud and sounds great. I have intake and exhaust, nothing more.

 

i have a straight through exhaust and i can easily hear vtec at 4400 and my secondaries at 5800 under WOT....if you cant hear that i dont know what wrong with you....my is loud only under WOT though
