when does vtec engage on a d-series. . .the one that comes stock in a 98 civic ex?

tek_civic

i believe around 4800-5000 rpm, whats up? can't feel it? lol, neither can i, not yet anyways .

hardcorepreston

lol I know what you mean with the "cant feel it?" i was making sure i wasnt throwing codes and making sure i had enough oil for weeks.

on a single cam it is only one side of the cam. not like the dohc. so it isnt as "audible" as the dual cam.

on a d16y8 its 5500rpms. I can't feel or hear it either. oh well.

tek_civic

ya but on a completely stock car you should be able to hear the whine of vtec when it kicks in, i made a light that runs from the vtec solonoid to help me know when im in vtec! actually since i did a few more mods i can feel a little vtec and definently hear it.

Modify your airbox so the airfilter is exposed. You'll hear it. I know I do.

VSM EXtasy

i have an AEM cai and i can't hear it.

WongFeihung

i have I/H/E, and i can hear it...but feeling is another story.

8200RPM

I have an intake and I can hear it! Engages around 5800 RPMS I believe (possibly 5500)
Yes I have a sohc- dont be fooled by my user name

i had a greddy turbo/hondata. Redline was set at 8400rpms. When vtec kicked in at 4400rpms the turbo hit full 14psi and that was a vtec rush alll 229hp to the wheels

just throw in a short ram intake and mash on the gas and you will hear that bitch moan @ 4.5-5 x1000 rpm.

tek_civic

ya i have the following to help me hear and somewhat feel the MaD VteC yO!

short ram intake with heat sheild and cold air ramp.
greddy header
only an axleback exhaust
streight pipe
comp 59300 camshaft (best mod of all) untuned
had nitrous and on that you could REALLY hear vtec

NonovUrbizniz

I could hear it fine when it was stock... and it was a noticalbe jump in power too...

once the intake/exhaust were on it was even more noticable...

but now with a header/cat it kinda evened the power curve up... so now I can barely feel or hear it... it feels like it's more of a steady climb in power now...

Rezon

You can't feel it kick in as if a turbo just spooled up, but you can definitely tell the difference.
