Can any of you actually hear your vtec kick in at a certain RPM on your f22/f23 motors. I can't! I'm just wondering because one of my friends thinks my car doesn't have vtec because it doesn't change sounds like his b16a in his crx. I know it does have vtec, it says it right on the damn valve cover! My car just seems to continuously get louder the higher the rpms go, while all my friends rsx-s, gsr, crx b16, and even a civic ex has a noticable change of sound once they hit their vtec. Also does anyone know for sure when the vtec is suppossed to kick in on an f23? Someone asked this on a-cl.com and everyone gave a different answer. Thanks

 

i drove a 96 ex for 50000mi, and i never felt it

 

nope, that's once difference between SOHC VTEC and DOCH VTEC. DOHC VTEC actually has a cam profile for performance so when it switches you feel and here it.

 

accord sleeper-thats exactly what i thought, but yesterday i drove my friends 00 civic ex, (d16 single cam) and his godamn vtec sounded exactly like my friends gsr. All the civic ex had is e/cai/4-1 headers. This is why I was asking.

 

it's because you don't have a dohc vtec engine. the vtec engagement on dohc engines is much more audible.

 

anyone know why the ex civic single cam has a cool sounding vtec then?

 

i've driven a d16 both versions the 93 version and a 00 version, i didn't notice VTEC like i can in a GSR or Lude. maybe the mods help, but a GSR or Lude has a very distinctive growl when in VTEC land.

ie: i went to to a meet last month with a bunch of guys mostly ludes and they decided to take off a light kinda fast so i took off too. the guy who was behind me comes up to me after we got to where we were going and said "do you got a motor in that thing" and i was like yep. he could tell i had an H22 and not the F22b1.

 

BLOCk,
Do you even have a intake or CAI on your accord?

Because i know when i hit Vtec in mine because of my CAI. MY vtec is around like 5 or something thats when i hear the vtec time in. Because it sounds a whole lot different and you can hear it better. True DOHC vtecs are much more audible. expecially with a cai or sr intake

 

i can hear mine kick in, it seems to be louder if i have the AC on for some reason, i took the resonator off, and now it sounds more like a civic when it engages. But yeah i know what you mean my freind has a civic, with all the intake/exhast mods, and iot ROARS when it comes on.

You may also want to check your oil, VTEC wont engage if you dont have sufficant oil.

 

and my VTEC kicks in around 4800
