Well many of my friends who also own preludes, you can hear vtec kick in at high rpms even for automatics, my car is a stick and the only time i heard vtec kick in was when i first got the car, everybody that had rolled in the car with me said my vtec doesnt kick it, therefore it must be the vtec solenoid? but my dad started yelling at me saying im so stupid, that if vtec was to fail, there would be a check engine light coming on. Well i was wondering should i listen to my dad who havent ride in my car and said there's no problem or listen to some friends who find a difference by RIDING in my car and comparing it to theirs. Is it possible for VteC to fail without the check engine light coming on?
Well, my oil is at minimum i think, does it need to be at max? and my car had always been warmed up everytime i try and smash. And what else can be wrong with VteC without the engine light on...
As others have said, check your oil. Also, keep in mind that VTEC kicks in at exactly 5,200 RPM for a 5th gen. The moment it hits that RPM you will hear the engine get louder.

Yea, if the oil is on the low side, it makes a big difference. I learned this on here right away. Also, as they said vtec does NOT kick in at all until over 5k rpm's. Maybe you are just being too sweet on your lude. Hit that gas pedal hard, don't be skeered.

One point I would like to add:
If you still have the stock exhaust, and resonator; VTEC engagement is not nearly as noticible... I mean,,, on my car, it sounds like a jet is taking off at 4600 RPM; but back when it was stock, I only felt the power difference; I never really heard it.
However, it is possible for the VTEC Solenoid to go out, and not throw a CEL. Also, if there are electrical problems in your car, the ECU will go into limp mode, causing no VTEC, and a 5.5k-ish redline (not sure about the exact number)

Don't some cel codes shut off Vtec? I am pretty sure I remember reading about that while I was rummaging through old posts..
And to the guy who said something about a search function.. I hate the fact that every forum has at least one of you. This is NOT just a question and answer database, you don't know if he has already tried some of the ideas that those threads may suggest.. and if you know the answer, DONT BE LAZY.
Doesn't take but a second to share your information.. while sorting through threads can take minutes, hours or days. And that is considering the person with the answer didn't mispell the problem, and we KNOW vtec is constantly spelled wrong.
I guess my basic thoughts.. if you don't have anything positive to say, why post? There are a million reasons his VTEC may not kick in, and his assumption may be hasty.. and we are here able to tell him that.

You've just answered my question kinda. Anyways i do SMASH on my prelude, i dont pussy gas that i smash on it, and i notice a difference at high rpm but people just tells me how their car you can hear vtec and mines just sound like a loud engine noise...so maybe i need an exhaust and intake, but anyways if that is vtec, then god damn the prelude is somewhat slow! cause in my homeboy's integra gsr, somewhat modded port polish head 2step the car and hella **** to it, he smashed in that and i was in it and it was scary, so i tried on my prelude just stock, and it just felt somewhat slow...and my other homeboy's accord v6 auto is quick....so i was thinking prelude is just slow??? or i need to get to third gear, cause i never get to max out third gear before reaching another car on freeway (bay area) or the strip of road too short..=/
I read your PM vietboi, just try searching for 'VTEC not engaging'.
yeah i used the search function but my vocabulary is not that big, i forgot to try something like Vtec Not Engaging, at first i was just searching vtec solenoid and etc. so why you think i decided to make this new thread..
I read your PM vietboi, just try searching for 'VTEC not engaging'.
Just trying to remind you why there are forums, they aren't here so you can tell someone about the search function, so why don't YOU stfu and stop trying to chase away members.
The guy has 7 posts and it doesn't take that many asshole comments to get someone to disappear.

Do you know, that if you search the word "search", it comes up with 3x as many hits as the word "prelude"?
The "search function" spam is a dead horse.
This is a valid question; that requires it's own thread. All of the other references to stock vtec engagement sound are so out of date, that the information is likely to be unreliable. Over the past 4-5 years, people have found new ways to fix things on their cars, and their not worried about going back and editing a thread that they posted about it 5 years ago.
In any sence, back to the topic at hand:
The Accord V6 Auto will pull alot harder; i-VTEC... not really a "better" tech, but the engagement is alot more pronounced. Not to mention the 2 extra cylinders.
The GSR: .... do I even have to explain this one? =D Obviously, he has put a bit of work into it; either a lower engagement point, or simply an exhaust system; to make it sound like a jet when it hits VTEC.
A stock prelude would have trouble keeping up with either of these cars; let alone modded versions of them.
The prelude is not by far, the fastest car in the world. The reason it gathers such a big fan base, is the mixture of everything- Style, Efficiency, Luxury, and Sportiness (is that even a word?); all in one SOLID frame (REF: SOLID- look at some of the accident stories about preludes; they hold their weight VERY well)
The prelude was the flag ship... or test dummy; for alot of different technologies, that were all brought together into one car. Before the prelude, there was no such thing as an affordable car with a SportShift transmission; acoustic feedback system; etc. Also, 200hp from a stock I-4 was unheard of at the time.
So, to make a long story short:
The prelude wasn't designed with just racing in mind. However, if you feel that your VTEC doesn't kick hard enough, you can pickup a VAFC for $250, and change the VTEC Engagement point to 4500rpm, so you can feel the rush. But by doing this, you will loose high end and fuel economy. The stock VTEC Engagement point is 5200 RPM; as stock, it is setup to keep a consistant powerband, without a real major difference when it engages.
However, every HP increasing mod you do, will make the VTEC Engagement more pronounced.
Just my -0.02

EDIT: One other note- On OBDII Vehicles, such as the 5th gen prelude; it is possible for something to be wrong, without causing a CEL light. Want proof? unplug the EVAP Solenoid; or the Intake Plenum thingie (in the resonator). Some Diagnostic things that the ECU notices still store as error codes, but as their not neccesarily bad things, it doesn't trip a CEL light.
Run one test on it- get on a clear stretch of road, ad floor it in 2nd or 3rd gear- listen closely as you pass 5200 RPM... You will notice the engine gets slightly louder, and the car pulls a bit harder. That is VTEC. If you can't hear or feel ANYTHING, take it to a legit honda dealership (not a chevy dealer that sells used hondas); and for $75, they will tell you if anything is wrong with the VTEC System.
My lude is entirely stock except for k&n filter. When I hit 5200 rpm there is a pretty noticeable difference. The sound does change a bit, even with a stock exhaust.

EVERY bit of the above information is available within the first 3 hits using the search feature. Instead of taking 3 days to get information from the people ignorant enough to post relevant crap, he could simple take two seconds to type no vtec no cel and he'll be on his way out the door in 30 seconds to check some things. **** yourself. Every asshole post is oriented directly at you hoping that these numerous posts will make you disappear. Get on some other soapbox, this ones surrounded by your black friends.

I guess that thread was okay because it wasn't available within the first 3 hits using the search feature? How long did it take you to choose which pair of pants to wear that day?
