Ne1 w/Vtec come here

[osmosis_jones]

What do u guys "feel" when the vtec engages, u feel lika boost or somthin(i already read the how it works thing on vtec) do u get a boost in speed?

[Moloko]

You will feel the engine pull harder because it changes the valve timing to be more aggressive. It will feel like a small boost because until Vtec engages Hondas dont make much power.

[turbo2.3]

it is like:


1000-nuthin, 2000-nuthin, 3000-nuthin, 4000-nuthin, 5000-nuthin, 6000-nuthin, 7000-a tiny bit of a surge that you will have to pay close attention to in order to be able to feel it.

close, up till 5000. Typically it will kick in about 5200, assuming you don't have VAFC. It doesn't feel like a whole lot more boost, nothing near that of a turbo, but you can feel a little and hear it a lil more.

[entix]

the boost you feel is horribly magnified by the fact that youre trying to feel it. if you werent paying attention to the tach and had earplugs in, you wouldnt feel much. most vtec cars pull pretty weak up to redline. stock i guess, to avoid getting yelled at.

[PC]

if vtec is working correctly on a stock car you wont feel a thing it is smooth as silk from say 2k all the way to 8k for a gsr. its like one long continuous pull..its kind of strange when many cars just run out of breath at say 5-6k to get in a gsr and it just keeps going and going. now i dint say it was fast just that it has a super wide usable powerband.

ive driven by bro inlaws 95 gsr with i/h/e, msd ignition, and mugan chipped ecu that kicks vtec in at 4900. i didnt really feel anything when vtec kicked in but his friends who work on hondas all day says it kicks in hard. i drive a non vtec honda and they got vtec.

[atomicbomberman]

haha

you can hear it more then you feel it really, it doesn't "kick" hard if tuned correctly, but you should feel the car to keep pulling and pulling and pulling....

[Swift]

when vtec engages u dont feel a jump like hitting full boost on a tubo car. but u can feel it pull harder in vtec than not in vtec.

[PC]

i dont understand why everyone wants this big surge of power...i mean its a 4cyl not a super monster motor ya know? it seems everyone wants to praise vtec as the almighty giant killer. im sorry guys its not and never will be. sure it may waste that stock car that thinks he is a racer just to give you a hard time in traffic but its not all that.

i have a friend who was bragging about how his turbo spikes up on the dyno sheet and i dont understand this either. he liked the huge vertical spike when the turbo spooled. to me thats just asking for the tires to spin.. id rather see a nice smooth curve personally. the dyno sheet in question was making 410whp at like 6k. he made plenty down low but it really spiked when the turbo spooled. i think he made 300whp at like 3500 rpm which is not bad. his torque was up there to like 370 or something.

i guess if you want to feel like you were launched out of a rocket tube then its cool but if thats the case go find a 500whp domestic that hooks up. all else will feel slow after that i assure you.

the sound of vtec or the effects of vtec to be more acurate make you think the car is accelerating faster than it is. its a phsychological thing. you really should feel no surge or anything diff if the car is mostly stock. the point to putting it on the engine was to have a nice wide usable power band and IMO they did a damn good job with it. it has no torque but it does just fine out in the rat race under everyday conditions. the rat race is how i describe all the yehoos going to work everyday.

[TypeIII]

A "surge" in power sucks... You want smooth power delivery.

yea and you can hear it especially well if you have a blow off valve.


im just kidding

[XTC Dynamic Supra]

vtec aint nothin but a fuel saver feature. That's all it really is. A small set of lobes for fuel economy and a larger set if you wanna waste gas.

[tbkonwso]

from personal experience... reg vtec is okea... but vtec in a all build na gsr motor is a different story. i acualyl shitted my pants cause the vtec ripped soo hard and loud and fast.. it was kinda scary.. i felt like my ear drums were shattered ..

incorrect, well sort of. it just lets engines that actualy make power at 8000 rpms, have a usable low end for daily driving.

so what you're trying to say is that hondas have usable power before 5400k. sure buddy.

considering what i just wrote, that was probably the dumbest thing ive ever read.

yeah you just said that it gives hondas usable power before vtec... but hondas rarely do! No horsepower or torque before vtec. It can help in hp a bit but not much in torque. either way you wanna think what vtec is it's plainly a fuel economy thing. you can produce similar peak hp with a LS motor if the head has the same flow characteristics, the came lobe is similar to what a similar vtec lobe would be, and if the compression is similar. Having vtec just allows you to have a car that will idle well and drive smooth for daily driving.

[PC]

hey i can and have built a car that idles well with a huge cam and easily pulled from 3500 to 8k doesnt take a rocket scientist to do this. this vtec thing is no miracle but it does work very well for the masses its just no race car not stock anyway. i wouldnt build a race car with one either although many have successfully..i dont see why people put a wild "vtec" cam in their car its kind of pointless. one of the main reasons they make no power down low is cuz they have some dinky little cam unti the vtec lobes engage. you want power you need displacement and decent airflow.

the stock hondas with vtec do just fine for their intended purpose nuff said.

sorry to beat a dead horse, but i need to correct something here.

a non vtec motor, and a vtec motor with the same vtec lobe as the non vtec, will produce the same power. you understand this right? all im saying is the non vtec motor will have even less low end than a honda normally does. where as the vtec will have a drivable low end, which is useful for commuting.

[JGproSeriesG2]

All the honda race cars dont even use vtec... A lot of people have a fetish for vtec, they talk about it like its nitrous or turbo... But vtec has nothing on those two. When people say there vtec hits hard... I think damn that some shitty tunning, not a smooth power band.


If you take two cars... both are exactly the same, same weight, same power etc.

But one has vtec and one is non vtec. The non vtec car will win, because vtec actually takes power to engage.

THANK YOU! At least someone actually knows something about engine...

Myth: Modern Vtec system by honda came from formula 1...

Truth: Not anymore. Vtec was used for a while, but look how well BAR Honda is doing in the F1 champ... And tell me if Vtec is really made for racing. And no they don't use that anymore, because:
a. it takes power away
b. it's just about pointless
c. you don't switch cam lobe at 16k rpm...

The truth is, it's a nice system for street because it SAVES GAS. It lets you have 35mpg while still able to pull to redline. Think of it this way, your non-vtec lobe is the shit lobe that they add in for fuel economy. Most Vtec lobe are not agressive enough to gives you crap idle or crap torque down low.

[PC]

hey my car made 36mpg cross country with a healthy set of cams a header and OS valves + 2 carbs. you dont need no stinkin vtec to rev to redline and have good milage. my car would go from 3-8k in the power band. on top of all this it had a tired bottom end. think if i had some decnt bottom end i bet i could do better on milage!!!

[cbrakillagts]

I have a 95 gsr, and a 2000 celica gts. one's v-tec, the other vvtli. same shit, but the difference is the lift intel. in the yota. I think honda was going for the performance, not fuel economy. Its just like everyone said, you don't feel the v-tec in the gsr, but if it wasn't there you would sure as hell notice it. I'm not saying that v-tec is the end all in performance, it's just a little something extra.

[cbrakillagts]

JGproSeriesG2 "But one has vtec and one is non vtec. The non vtec car will win, because vtec actually takes power to engage. "


what the fuck are you talking about?

[alexokp]

it's all about potential and kinetic energy mayn

[tbkonwso]

i still think vtec is over rated

[The Steve]

I feel nothing on my car when vtec kicks in. I think either people are full of shit or they need a tune up.

The only thing is you can feel the car pull harder and you actually have a little power showng when you press the gas the car responds.

Mine kicks in at 3400 and is smooth as your lil baby butt.

[Mickee]

um no .. it doesnt kick in 3400... sorry......

Well that when i can feel the power start so if im wrong i stand corrected and that means its smoother than i thought and you help me proe my point even better

okay this isnt exactly stock ECU's but the stock is a bit higher than this... so yeah....

[reese]

I thought this was a racing site......... if you have a vtec motor and you dont feel or hear it crossover like many ppl have said you have no racing mods and your car is stock.

BTW the signal auto crx is a b16

[BLAH BLA]

small displacement motors make very little power at low rpm, part of the "v-tec kick" most of these guys feels is just the motor getting into the meaty part of the powerband. where th motor actually makes some power. most of the guys that say "my v-tec kicks in hard" have never driven anything truly fast or powerful to compare it to.
