Chirping VTEC?
So I know this might sound silly. But honest question, when your VTEC engages, do your tires ever chirp from the sudden power difference?
I have a 96 Prelude Si with an H22a swap, and the only mods engine wise are an Injen CAI, Clutchmasters stage 2 kevlar clutch, and ACT streetlite flywheel. If I start out easy in 1st gear and then casually put the pedal to the floor, more times than not the tires chirp at the exact time that VTEC engages. And no, my tires aren't bald, actually have about 60-70% tread left.

Lol, the point is to ask and see if anyone else's lude does this, or if mine is just weird. Everyone's response when I tell them is basically like street_ride14's response, they call bs and say VTEC isn't strong enough to do that, until I give them a ride and prove them wrong.
I'd try to get a video, but my lude is tore apart right now getting ready to be repainted.

Mine never did with stock struts, started doing it after I lowered it on Koni Yellow/Ground Controls. Sometimes it chirps all the way til redline too.
And yeah the tires are several years old so they are probably a little dryer and maybe not quite as sticky as a brand new set, but they don't have any other problems with slipping even if I turn quite fast, they still don't screech.

Mine will spin tires in higher RPM in first, but not chirping. Second gear spins a bunch once you first shift. Third gear chirps a little just going in. So I guess no, mine does chirp going into VTEC. Try it with new tires and see what happens.
i chirp my wheel non-stop if i floor my pedal on my stock h22 on the 1st gear(no hard lauching just release clutch and go),chirp my 2nd and 3rd all the time when i get my stock h22 only with aem cai and ebay lightweight underdrive pulley and lighter rims if i floor it back then when i only got 180whp for both case.Bridgestone potenza re001 17inches user here.That's pretty normal i guess since u got a lightweight flywheel.
I have never heard of any honda chirp the tires when vtec engages. Its supposed to be a smooth transition, not a sudden unstoppable power force that starts chirping tires because the valves open more. This is one of the silliest things I heard.

. But I agree with you, I have never heard of any honda chirp the tires when vtec engages either. That's why I'm asking here, to see if anyone else's does like mine does.I'm sorry your vtec in your 1.6l civic (nothing against civics) doesn't have any noticeable power difference, but that doesn't mean a motor that's over a half a liter larger than yours is the same as yours. Educate yourself more on all hondas instead of just civics, before making assumptions and calling bs on my question. If you knew more about h22s, you'd know that the vtec engagement IS NOT by any means a smooth transition like a civic's is.
Just for further clarification, yes I mean that in 1st the tires start slipping and chirp exactly when vtec engages, at 5200 rpms, never before, never after. No it's not a "sudden unstoppable power force", but it is definitely by far feel>sound instead of sound>feel like a civic/integra. I don't care if you think I'm lying, I know it sounds silly to some of you which is why I stated that in the first sentence, but I am not the type of person to start a thread about something that doesn't really happen. JuggerNaut-CTR, you're not the only one that says it's the silliest thing they've heard. All the domestic guys tell me that too that vtec doesn't add any power, til I give them a ride and they hear/feel it for themselves.
Where do you get off telling me that I need to educate myself more than on just civic's? you dont know me at all. On any and every honda/acura motor that has a vtec head, it should have a smooth transition...period. If yours doesn't that means its not tuned right (which by the way, there is a thread on here that discusses this). And im not even calling bs on it, i said it is silly, b/c it is. I have owned several different hondas w/ very different motor set-ups. I had a g23 accord, and a h22 euro-r crx that are the closest related to your motor. All my motors have been tuned and all have had a smooth vtec transition that is set by the tuner where the horsepower and torque curves meet.
hahaha, so I was in the middle of typing this up, walked away for a little bit and came back, still confused on what the bloody hell you must be talking about. I read your 1st post again and lol'd when i read this....
This sentence explains it. Aside from you being arrogant and cocky, Im pretty sure your over exaggerating a little bit. I will show you some love if you are at all capable of posting up a video of this magical accomplishment. Been around honda's for almost 10 yrs. Been around everything. Been in a lot of cars with great set-ups and have never been in or heard of anything like this. The only thing I think your actually doing is is dropping the clutch a lil right at the crossover. Good luck at whatever you are trying to find from this.

Did you not see the couple people earlier in the thread that said theirs does it too sometimes? If all vtec engagement is smooth all the time, explain to me the sudden jump in hp and tq on a dyno curve when vtec engages. It's not a crazy burnout or anything lol, just a faint screech of the tires slipping. You're acting like I'm telling you that vtec is so mad crazy that it smokes my tires off when it hits.
And sorry to disappoint, I would show you my magic accomplishment but like I said, it's tore apart right now and will be getting repainted. But when it's done mid-september, I will post a video if my crappy droid video recorder can hear the tires slip. Don't worry, OP WILL (try to) DELIVER.
Did you not see the couple people earlier in the thread that said theirs does it too sometimes? Nope...I read others saying that theirs chirp all the way to third...that means people are confussing "spinning the tires" w/ "chirpping" the tiresIf all vtec engagement is smooth all the time, explain to me the sudden jump in hp and tq on a dyno curve when vtec engages. Wtf is so hard to understand the transistion is supposed to be smooth, not hit vtec and bam I chirpped my tires b/c of quote on quote..."the sudden power difference" It's not a crazy burnout or anything lol, just a faint screech of the tires slipping. You're acting like I'm telling you that vtec is so mad crazy that it smokes my tires off when it hits. Hit the nail on the head

I don't understand you guys...maybe you should read and/or do research before posting. Looks like I'm not alone but you apparently filter what you want to read and what you don't...
Here's some visual proof for the naive:
This is a mostly stock CTR on a dyno. You can see a slight curve where crossover is, but I agree with you on this motor, you could say the crossover is a smooth transition.

This is a stock H22a on a dyno.

Do you see how the curve is MUCH larger, and is more of what you could say, "a sudden difference in power"?
Still don't get it? How 'bout some math. Before vtec, HP increases steadily at about 2.3hp/100rpms. Until vtec. From 4900-5200, "all the sudden" the HP goes from 108hp to 130hp, in just 300rpms. That's an increase of 7.3hp/100rpms.
Now when it's a steady 2.3hp/100rpm increase then at crossover it jumps it to a 7.3hp/rpm increase, I would say that's not really a smooth transition if it it suddenly over triples the hp output per 100 rpms for a short time when vtec engages.
You could've just said, "No, my crossover is smooth and I can't feel a torque/horsepower difference" instead of telling me it does not happen with my car when I've felt it hundreds of times exactly AT CROSSOVER. I'm sorry your motor doesn't act exactly the same as mine.

Cool, I don't care if you think I'm full of s*** or not, hate on me for how my car (and the others that agreed) acts if you want I guess. It was a legit question (backed by evidence and a graph that shows H22a's do not necessarily have a "smooth transition at crossover") and you don't need to reply if you're just gonna flame and say "no, I think it's all bs" without saying why or backing proof that my car doesn't act how I described.
Mods, I could definitely understand if you would lock this from all the people flaming and calling BS just because they assume I for some reason decided to make a thread about something my car doesn't do.
Thanks to those of you that were helpful and didn't flame me and posted reasons why it could be doing this
Helping is what this forum is supposed to be all about anyways, right?
