VANOS/double VANOS, VTEC/i-VTEC

[M3boarder]

i dont know all that much about each system, but i know vanos is better since its on all the time as opposed to just in higher rpm's.....im debating which is better right now with someone though and i just wanted to know how much of his statement was true...

"The only VVT from BMW which compares to VTEC is their DOUBLE VANOS. The new i-VTEC is above Double Vanos.
Just like there are different tyes of regular VTEC, Honda will soon imporove its VVT and make better types of i-VTEC to once again hold the title of the best VVT system in the world, like it once did with it's previous different forms of VTEC. And Yes, there ARE different types of just regular VTEC. The S2000 VTEC, although not i-VTEC, is more advanced than TypeR VTEC for example. Both cars are still not i-VTEC, but the S2000's VTEC is still more advanced."

someone educate me

[Alibabajun:.]

your paragraph is a little confusing to me,
but from my knowledge, i know of the two different vanos/v-techs.
comparing the Type R with the normal honda's is like comparing the m3 vanos with the 328. I dont think it would be any different on the same car.
and plus, how would you make one variable valve timing better than the other? there is only one perfect margin of variable timing you could have, i dont understand how one could be better than the other.

VANOS (as i understand it) is very different from VTEC. In a VTEC motor, when a certain RPM is reached, a mechanism in the motor shifts the cam operation from the low lift lobes to the high lift (VTEC) lobes, thereby increasing power yada yada yada.

VANOS is a changing of cam timing to suit conditions for more torque or HP as necessary. someone please correct me if i'm wrong about that.

I-VTEC is kind of like a combination of VTEC and VANOS, I *think* dont really know or care about it.

The ITR and S2000 have very similar types of VTEC, the only difference in them ( and any honda VTEC motor) is the aggressiveness of the changeover, and the rpm point where the changeover occurs. i-VTEC is something different.

by the way, see my avatar for 'VTECH'

yes you are correct. My arguement to VTEC is that vanos is in a bimmer and vtec is in a honda. Bimmers are better so VANOS is better.

[Rob ITR1035]

you know your car is slow right?

[scottycs]

Are you a ****ing idiot?? Just from reading that I feel ten times dumber than I did this morning.

I love bimmers (and I think they are better than hondas), VTEC is far Superior to vanos.

Rob is right. VTEC is better.

I have trouble believing that the VVT system on a $35k Honda S2000 is better than the double Vanos system on a $75k BMW M5. Is it just me? Seems like you can't really aruge this point. If you could put the two different systems on any car and measure performance gains maybe then it would be possible. But this is like saying chocalate syrup is better on vanilla icecream than butterscotch is on chocolate icecream. Put both syrups on both ice creams and compare. Since you can't really put VTech on a bimmer or Vanos on a Honda, why even argue? Seems like you would have to just measure the performance of each car in its entirety against one another. E36 M3 vs Honda S2000 maybe?

[scottycs]

Please shut up, while your still ahead.

Don't talk unless you have a clue what you are talking about. Vtech is better, simple as that.

Think about having stock cams in your car till 4k, then putting schrick cams in. That is what Vtech does.

I can, cause I actually know what I'm talking about


VANOS is changing of the cam timing
VTEC is changing the actual SHAPE/LIFT/DURATION of the cams, like two sets of cams....


you decide which is better.

price be damned.

*shakes head*

I can't believe it. "Screw the technical merits of either system, whichever costs more is better!" BTW, s2k vs e36 M3 and the s2k wins.

When ignorance hits $35/barrel, i get the drilling rights to your head.

[scottycs]

Much Ignorence here, no doubt.

But don't push your luck with that quote. From my experience I have found it quite the opposite. But that is another discussion.

LOL, yeah its pretty funny though. just sucks for me cause I am automatically wrong since i own a honda....


as for m3 VS st00k, well it should be s2k vs whichever Z cost $35k, then see who wins...but that another discussion. I think we've answered the question. thanks for the support btw chris and matt.

[scottycs]

Hey Rob, atleast you drive a mad tight honda though

As your sig says "Type R's are really only good for street racing.....only straight line type stuff. They're not the best handlers...."
