What is it about the vtec you like

  

dinzer -> What is it about the vtec you like (5/24/2005 7:47:06 PM)

So im driving home on 287 tonight and some guy in a probably 2000 ex is pushing up the road.

gad to be same enging as mine 3.0 v6, palte was 9tee9 if you in here somewhere!!!!!


He and i echanged the lead for a good 20 miles pushing 80 to 110, it got me to thinking about
just how great a vtec is. I was wondering what the accord buffs out there have to say about their
vtec, one guy in this formun calkks it his "stock beast" good choice.

Who out there feels the vtec perfomes better in the 0 to 60 range, it is nifty, or where i like it

In the 80 to 120 range where if you punch it it still responds. since im thinking a putting a charger on mine, where while this increase my performance, accross the board or more so in one specific area.

How about top speed, wil the supercharger get you in the 140 range, i kinda top out at 120 125 right now.

as always i do appreciate the varied feeback from every one who responds.

I like the sound of the word itself....(immitating Homer Simpson voice)...mmmmm....V-TEC [:D]

i wish they made a supercharger for my car [:(]

I agree with you for a Change Evlampius..I also like the sound of the name...V-Tec[sm=burnout.gif] WheelBrokerAng

I've got the 2.4l manual and I like the fact that it has low end grunt as well as punch from 4500 RPM on. All this with A-1 MPG, couldn't ask for more........except the V-6 six speed in the sedan!

habeel -> RE: What is it about the vtec you like (5/25/2005 9:56:30 AM)

I dont have V-tec! [:(]

VTEC isn't some power thingy, it's for fuel economy at lower revs. it actually retards the timing below a certain RPM. so, when it opens up at 4k rpm or whatever, it feels like it's adding power, when it's really just giving back what it took away. AND, almost every car maker has a form of this in their cars now, so it's not like we're special (from bmw's VENOS system to toyota's VVTC, etc.).

</rant>

sorry to rant, but i wish everyone would shut up about how cool VTEC is. it's nice, but not for the reasons y'all keep mentioning. and yes, i have a 3L VTEC motor in my honda, and my last car was a VTEC civic (1.7L), so I do have some idea what I'm talking about.

my vtec is ok I the top speed I've ever done is 110-120

accordlowered04 -> RE: What is it about the vtec you like (5/25/2005 1:04:25 PM)

i dont have a v-tec in my car but it does get up and go for a stock motor. I have outran some v-tec's around here. So my question is what is so good about v-tec's? I mean i raced my first v-tec thinking he was gonna kick my tail but instead i beat him by like a bumper or so. I recently raced my last one on the interstate also the other night on the way to school and he pulled up behind me after we got to school and wanted to know what i had under the hood and flipped out when he found out that his 2000 v-tec got beat by my just basic honda engine.

dinzer -> RE: What is it about the vtec you like (5/25/2005 7:22:33 PM)

I test drove a caddy cts last week, a freind of mine, brand new, from the showroom 255 horse power, not sure of the other details,
first thing i noticed was the pick up was a lot slower than the vtec, even with what steev was saying about power benn taking awaw before the 4000 rpm level. Now i dont know the official times of thes cars but i know 0 to 60 i could get there faster than this new caddy
and that gas some extra horses on engine. just and observation, personally i love the vtec from the first time i drove it.

have to aks again though, will supercharege increas my top end speed or just get me their quicker, no problem wiht the latter of course

accordlowered 04, so what is in that thing?

First, Toyota has VVTI...yes many other manufacturers now have their forms.
Second...VTEC doesn't reduce power...it saves gas mileage and increases the low end powerband (low rpm torque) by providing a low lift cam lobe...once the rpm raises and the map sensor detects the proper pressure and amount of fuel VTEC kicks in AKA...the cam lobe changes to a high-lift profile allowing more air to flow pass the valves and to the combustion chamber and provide better top end (high-rpm hp). Since the engines are small and efficient they are already great on mpg, but VTEC basically cahnges the powerband according to the factors that the ECU measures to activate VTEC. It's a take to make a small engine build more torque when it's best and more hp when it's best. Horsepower doesn't get you off the line...torque does.

Well said. [sm=usa.gif]
Essentially I shared the same thought in my post above but not as eloquently as you put it.

habeel -> RE: What is it about the vtec you like (5/26/2005 9:13:21 AM)

is vtec then essentially synonomous with a double overhead cam?

ie. do vtecs only come with DOHC? Or can it work witha complex single cam system?

VTEC actually only operates the intake valves...I'd say most of us with a USDM F-series or J-series engines has a SOHC...and most have VTEC also. So you don't need DOHC to have VTEC. The cam lobes you can think of as the rocker arms locking together to raise the lift. With DOHC it will lift the intake camshaft only. With SOHC cam the system is designed so that (yes their is only one camshaft that operates the intake and exhaust valves, but can use variable valve timing on the intake side.

I love good engineering, I need to GRADUATE! It's simpler than it can be explained, but more complex to understand if you are unaware of the design and how the design works.

I'd advise anyone interested in understand things check out howstuffworks.com (the automotive section) and read some books free at Barnes and Nobles. You'd be surprised at what you can teach yourself to do. Take notes to understand exactly what your engine does and when it does it. Even buy a Haynes manual from Autozone and read it. You'll learn things are easier than they appear.
