Title: VTEC
Post by: Omega man 2 on 11 March 2009, 20:11:54
Is vtec overrated and overplayed by boyacers?

99% of all vtec (or at least cars with vtec written on the side) over here are around 1.4 and compared to a v6 have p1ss poor performance.

My cousin dropped up last week in his 1.3 vtec civic and said it would wipe the floor with my mig. A point that was soon corrected ::)

Anyway, I thought Japanese hatchbcks were for economy??? and are massivly overhyped.

It works well but, you end up with a screamer on these smaller engines which boast high BHP figures but no low down torque!

The FTO Mivec (Mitsibishi's vtec) that my brother had could move well. Still no substitute for [size=8](Senator)[/size] cubes though!  ;) ;) ;)

My mrs's 2.2 prelude vtec will ..... i am ashamed to say :-[ ,beat a 3.0 mig :-[ BUT she has a mugen manifold and a straight thru exhaust and it REALLY kicks off !

So i dont know about the smaller ones but the 2.2 is definately a force to be reckoned with   :D

Just from personal experience of course before i get banned or lose my post count etc  8-)

The Honda vtecs go well for their capacity, but you have to scream the nuts off them. Obviously, no match for a well serviced v6

It depends where you're going to play. Small go faster hot hatches etc will leave an auto Omega for dead at the Traffic light Grande Prix, but one you've got 1700kg of Omega moving, then you're going to rapidly gain on them. 'Playing' on the motorway stacks the odds up more in favour of the Omega. :y

Funny hers seems to be well balanced as its their off the lights as mentioned but its there right the way up to and beyond motorway speeds, but being an import you cant tell what its had done to it!!

Dont knock old school vtec!! My last car was a jap import prelude J reg with the first of the 2.2 vtec engines. An auto, its torque figure was nothing to write home about, but in std form it made 197bhp. I did a few light mods by fitting a cda induction kit, sports exhaust , magnecore leads and iridium plugs and got it remapped with a dastek unichip which altered the vtec actuation point to around 3000revs. As an auto she redlined at about 6400 as opposed to 7000 but still did 0-60 in 6.5 secs and made 183bhp at the wheel . The vtec wont kick in straight away as oil pressure and engine temp need to be at correct point first but the feel of your head hitting the headrest as it kicks in and the car surges ... :yOh, no turbo lag either to worry about. Top speed wouldve been about 130mph, tho as an auto I couldnt get it delimited from the standard jap limit of 112mph. A great car to drive with (as fwd) good road holding. Much heavier than the Integra of course but then it had a few more creature comforts. Only downside was small boot and back seats designed for midgets!

My MV6 Auto is 7.7s 0-60 on my dodgy timing without lauch starting it.  I have embarrassed a Type-R civic who thought he was quicker than he was ::)

Haven't been able to get a good launched start timing for the tractor, as every time I do it, the revs go up, the speedo goes up, but the car doesn't move.  Then I phone up Black Circles, and give them my credit card number ::)

Why couldnt you get it delimited as an auto?
I have had 125 out of hers ( on a private road very similar to the a69  ;) ) and thats an auto, i also know what you mean about temp etc, when engine is warming up it wont vtec until the temperature is high enough to safe gaurd the engine >:( And you can guarantee the boy racers wanna play when the engine is cold  :'(

A manual with quick reactions and good clutch work plus the low down torque of a big engine, for me has seen off more than just japanese flymos, also the likes of passats,audis. It's just a case of getting up over 30mph before a high rpm/low torque engine can reach its peak power.

Not on a public road of course

Dont know exactly why I couldnt get her delimited other than the fact that the "normal" route couldnt be taken because it was an autobox . The place I got all the work done at has a very good reputation and so , although disappointed, I really didnt query the point . At the end of the day I wasnt going to use it for track days so wouldnt really have a use for 130mph. I do remember that after I got it I gave it a blast one day on a quiet stretch of dual carriageway and she roared up to 112 with obviously more to go then the limiter kicked in and its really bizarre its like your building up your speed and suddenly someones changed down to 3rd for you!!

I remember just over a year ago getting really silly 0-60 times, definately under 8 seconds (found it 7.8), so drive it well and you can embarras most things.

With a 3.0 I out accelerated a Renault Scenic up a bypass - that was fun, and I was taking my caravan for a service ;D

agreed..on the long run miggies are faster..

lower geared 2.5/2.6 should match 3.0 to around 50ish, when the extra cc start to show :y

i've got some more diag software, some of which can do 0-60 timings, will have to see if it works with my car...

ive raced my miggy with a few boy racers and the miggy is quick the manual also has a bonus of long ratio's once the v6 is over 4k its a force to be reckoned with :y Mivec is better than I-VTEC as it can be tinkered with electronically i know of a Mitsubushi Cyborg thats running 250bhp with no turbo and for a little 1.6 thats preety impressive

i from experience of owning a vtec before my omega.  i had a jap import 2.2 vtec prelude  oh how i miss that car.
i found her to be reliable and powerful.

here is a pic of her.   ignore my ungly figure in the driver seat  haha    ;D ;D

I agree with TB about having a high reving V-Tec. I have still got my Honda Civic Vti in my garage. Been there for over a year. Enjoyed driving it while i had it but just love my Elite more. Power and luxury :y. About the same economy on a run but my elite is around 10 mpg less around town. Loathed to get rid but S.W.M.B.O is starting to press for me to sell it. Still, it could pay for a new stainless exhaust system for my miggy and other goodies  :) But don't tell her that!

Nooooo surly she would like a new washing machine or s super duper iron :y

Nooooo Vamps! I will just sell and not let her know. She never goes into the garage anyway. She has all the latest domestic appliances to keep her happy in the kitchen etc. anyway ;D. A nice stainless exhaust and goodies will make me happy. :y

Lol, I have to laugh at the 'lowering the VTEC' point giving more power crap.....

It might give the feal of it but wont actualy deliver any, it probably actually reduces it for 500rpm!

Remember that 'VTEC' is only the addition of an extra cam lobe which is VERY lumpy (if it ran on this at idle it would be as lumpy as HELL!)

When a certain level of revs is reached, the 'lumpy' lobe is engaged by locking the rockers (yes, they use rockers!) together which means the lumpy cam takes over fromthe two standard ones.

The i in iVTEC mean it also has variable valve timing.

Nothing overly clever about and nothing very new either!

So, on the larger engines the low down torque should still be ok as you run reasonably large valves on reasonable cam lobes.

Its the small engine that suffer as they still need quite big valves to get max effect from the VTEC lobes.....this results in lower gas speeds at lower revs and poor output power.
