terrible bait

must be american

marketing for boy racers.
pointless for a race car, pointless for a street car except for hooners.

constantly variable is better, or multi stage like the new vtec. performance wise it offers little since "race" cars are rarely if ever out of a 2k range of rpm and you dont want the extra complexity or mass.

its good for mpg though if thats what they're using it for.

once electronic or pneumatic valves are the norm it will be a lot better. very accurate infinitely variable timing and lift and then it can be a big improvement in performance or mpg as a whole i think depending how it's tuned.

but as most of the systems are now it's for hp numbers and for hooning.

>>15064133
Useless unless paired with Super Eurobeat.

The two, combined with a few simple mods let an EG Civic hatch set a record Burgerring lap time.

it just kicks in

>s-so when's the VTEC kicking in?

Overhyped shitboxes desu.. Not saying they aren't fun and good cars cause for the price and fwd they're hard to beat. But VTEC is so fucking gutless.. Honda should've just turboed cars instead of fucking around with vtec.

>>15064209
ivtec is the same as single cam vanos.

i like it because it's meant for mpg. that's what all variable timing and lift should be for until it's advanced enough to do everything at all ranges.

>>15064250
the whole point of vct/vvt is that it gets you power and economy/driveability.
it's not about just one thing.

>ITT clueless people talking about VTEC
K no other manufacturer can put out the power Honda has with 4cyl unless it's with a turbo.

>>15064287
>can
yes they "can" they just didn't need to as they didn't built their performance/marketing strategy around it.

>>15064287

Buttblasted fuckboi detected

How's ur k swapped coupe going swaggot?

>>15064261
The more advanced ones are. The old ones aren't, vtec certainly is only for power.

I mean I guess i'll just retype my first post for you.
When they are more advanced and using pneumatic and/or electronic valves they'll be able to have infinite maps over the entire range for all purposes. but as they are now, it's still 2000 tech.

>>15064261
in a certain range is the point.. you cant affect the entire range without a variable map on both cams. the current lift systems are linear and mostly only on intake. because that's the easiest and cheapest way to do it.

you need electronic or pneumatic actuated valves to completely control the timing and lift in a non-linear way.

>>15064347
you can't say vtec is only for power or only for economy, it's illogical.
that's like saying twin choke carbs are for power not economy.
the idea is that you get both.

>bigger valve profile
>not for performance
>ever

>>15064388
it's not illogical. you don't get both.
vtec is a completely different cam profile whose profile is not meant for economy at all.
economy and power are not inherently linked.

when you hit the gas and open up a secondary choke you are not getting better economy.

>>15064451
ur dumb

>>15064133
Variable cam technology is always cool no matter the label. But shitposters love honda so this thread is already beyond saving.

>>15064451
no it's illogical because they give you a power and an economy cam profile.
it doesn't make sense to say they added an economy profile as a bonus, or to say they added a performance profile as a bonus.
you get both, end of.
yes when you open up the secondary choke you don't get economy.
but when you don't, you do. that's the point.
it's really simple.

>>15064322
Sitting at a cool 280whp thanks

>>15064451
You get the MPG-tuned cam profile down low, and the power-tuned cam profile up top. It's literally made to give you both power and economy.

>>15064465

>>15064451
>vtec is a completely different cam profile whose profile is not meant for economy at all.
and this is where you are wrong. the performance lobe is not vtec. it's just a performance lobe.
vtec is just honda's concept and mechanism of having two cam profiles on one shaft

>>15064347
There was vtec-e and three stage vtec in the 90s.

>>15064536
Thank you captain obvious.

>>15064483
not at the same time you fucking dunce. youre compromising one for the other. welcome to engine tuning 101.

>>15064587
Obviously you won't get economy when you're in the high RPMs on the performance profile. It just means you have an engine that can do both economy and performance, depending on the situation.

>>15064578
sure it's obvious but the guy i replied to didn't seem to get it and thought the performance lobe was vtec. maybe taking the vtec just kicked in thing literally?

>>15064587
but no one said it was at the same time...

doesn't that mean the crossover point is set wrong?

>>15064632
imagine their faces at honda when the guy working on vtec comes in to work one day and shows them this shit

>>15064133
It's just regular variable valve timing.

>>15064825
not really

>>15064825
>vtec
>timing

why haven't you killed yourself yet?

>>15064626
It's just a stupid thing to say.
>vtec is just the name of the technology
>it's not the name of the cam profile
like.. what. you're just stating the obvious for no reason and not actually making a point.

>>15064602
see my first post. it says nothing about vvt or vvl being bad, it's good.
it just says race engines don't use vvt/l because there's no point they are built for the top 10% rpm range and they don't need the extra mass of another profile or the complexity of a hydraulic system for no reason.
so it's market is stock engine hooning. which for me is pointless, so my opinion is that it's pointless.

if I want an economy car I'll buy an economy car. If I want to go fast I'll build a car to be fast without economy as a priority.
I don't need to pay more for a marketing gimmick I don't need or want. the op asks for opinions, not facts.

but, when they allow the entire valve assemblies to be pneumatic or electronic you'll see them in race cars without cams at all.
even for club racing the first thing you do is remove vtec, vanos, etc.
as of now no F1 car or LMP1 car uses vvt/l even though there could probably be gains from it even in a small rpm range.
but not enough to justify the weight or complexity at this time is my guess.

vtec does change timing.. you can see it in the lobes.
you should probably stop commenting on things you have no idea about.

yeah i suppose but cmon man thats stretching it

>>15064946
I did not laugh indeed, but it was certainly something like "haha look at this retard"

>>15064941
>>15064925
it could be variable timing if they wanted it to be. all they would have to do is rotate the other lobe.

>>15064858
>if I want an economy car I'll buy an economy car. If I want to go fast I'll build a car to be fast without economy as a priority.
Some people want a somewhat fast car with acceptable economy when needed.
There can be multiple reasons for this, such as not having enough space for two cars or just plain not enough money to own multiple vehicles.

>>15064972
yeah but it isnt so what's your point lmao

>>15064972
thats what i-vtec does, but regular vtec is variable lift

>>15065000
The name is wrong then?

>>15065013
probably

after all it should be VVTLEC

>>15064925
>>he belives variable valve timing means longer duration
it does

>ITS NOT VARIABLE TIMING
>YES IT IS
>repeat
nice thread guys

It's cool, but I laugh when I see someone that put different pistons, con rods, and a turbo on a motor and still has vtec.

>>15064133
Its nothing amazing but its still good considering how many companies now have their own version of it

>>15065049
so what would u suggest removing vtec?
>lets downgrade the valvetrain because anon said so

>>15065032
not really

variable timing changes the timing of the camshaft relative to the crankshaft position it doesnt change the duration of the lift

variable duration does changes the amount of time the valve is open

surely the same system can work for both, but its not the same concept

Every good car company now has their own vtec. It's an old meme since Honda hasn't produced any car worth buying nowadays

>>15064858
>like.. what. you're just stating the obvious for no reason and not actually making a point
yes, because the person i replied to didn't understand "the obvious".
i simply wanted to correct him, not make a point.

>>15064858
Variable cam/valve shenanigans are banned in F1, not sure about other motorsports

>>15064133
It's vvt
Every brand has it under some marketing term

It's okay that you're retarded, but don't think its something special

>>15069221
Clueless busrider.

>>15069227
>yfw I own a honda
It's a simple concept, man. I don't understand how you have trouble with what vvt is

>>15069268
vvt is advancing and retarding the cam sprocket

I used to think vtec was cool before I bought a turbo car. Now I think it's just cute. Like babbys attempt at emulating a turbo car. Or the guy up there bragging about 280 whp

>>15071399
what do you mean?
it's just variable valve timing, so you have two cam profiles (or more) with one set of camshafts.

>>15071742
That's not variable valve timing. Vvt is sightly turning the cam so the events happen at different TIMES. Vtec is variable valve timing of both cams AND variable valve LIFT.

In 1992 this allowed honda to make a 200 hp fuel efficient 4 cylinder. Everyone was BTFO with their 200 hp 6s and 250 hp v8. Everyone stole. Vtec is GOAT.

Do you know what tsukuba is? Have you ever played gran turismo? Its a fucking go cart track.

Lol everyone hates GM

VTEC is just basically adding more fuel when you punch it. Valve timing electronic control. Damn near every car nowadays has VTEC

Nothing
