Keep in mind that BMW just applied their new Valvetronic design with softcomputing techniques within this 2 yrs to the aluminium engines, which is the same idea as the Honda V-TEC.

Actually, valvetronic is not really the same thing as VTEC, although it does change the intake valve timing and lift. VANOS is closer to VTEC, but uses a different method of changing the cam profiles that allows for infinite variation but over a much smaller range of variation when compared to VTEC.

Valvetronic is primarily a system for throttle control and a replacement for the conventional throttle butterfly. The changes to the intake valve operation are designed to address throttle control rather than to switch between high and low RPM cam profiles.

It also differs from VTEC in that it does not operate well at high RPM and BMW does not use valvetronic in their M-cars for that reason.

BTW, I have been meaning to inquire as to whether or not your dislike of Hondas is borne of experience beyond a reaction to ricer culture.

If you are interested, I may be able to arrange an NSX ride in your area so that you will be better informed on the subject . . .

Not just that but vanos was around in 1993 in the e34 525i.

And the 1993 E36 325i . . .

Upping their quality of engines? What do you mean? BMW's never built a really BAD engine, or an unreliable engine beyond the nikasil issue with the early V8's, and some consider the original 5.0 liter v12 to be crappy (it's almost literally two M20 motors together) - but even so, that engine wasn't necessarily bad. The M50 is an amazing motor, and all since then have just been better and better. BMW's always built a quality motor - if you want to speak of quality we should talk about the run-away-subframes in the E36/Z3, interior quality, etc.

JD Power said they are upping their quality in how they build the whole car jeez [read] [chair]

Vanos was not software equipped

So that required no software upload. It was just an engine with DME - a circuit system. That means it is just a chip/microprocessor, which is a lot simpler than a computer. That just give you simple electric circuit language like 10111101110001.

What I meant in that post was I didn't think that the Catty lady had a chance to test drive the uncommon 316ti and 7-series with the valvetronic engine back in 2001.

I could have loan her mine 318ti.

You know after much thinking I realised that I no longer care for hating HOnda and really in my posts made above I didn't say anything bad about Hondas, atleast I don't think. I've driven plenty of Honda's (except for the reviered NSX or NSX-R of yours) and really find them boring. That being said I again remind you that I have tonned down quite a bit compared to how I was before and keep my personal aggresive comments to myself, not only here but in the real world. I don't want to drive the NSX but thanks though. Like I said my preference is European cars, what ever it may be thats just how it is, if you don't like something its hard to get someone to like it and thats how it is with me. I'd rather not bring this in here but I respect everyones opinions, thoughts, and likes that way everyone is happy. [:)]

I'm not hating anymore really, I look at engineering now and put that into perspective, the NSX is a good machine, and thumbs up to Honda for making a good machine. [thumb]

VTEC is old, I don't hear anyone talk about the i-VTEC [xx(]

thats just something I always wonder, isn't it better than the orig. VTEC?

VANOS is good technology and isn't VTEC's variation smaller than compared to i-VTEC's? I have no idea I'm just going with what I've heard. VANOS is very different but its meant for its own purpose, same goes for MIVAC, VVTi. etc.. I think they tend to go hand in hand with what their vehicles are built for.

Valvetronic is nice stuff I like it, if all the companies continue to improve their engines we should be able to see more good things to come, I just don't see anyone trying to improve the transmissions [idea]

Jason, you said how you have to whip the engine to make it work hard for you regarding the S2000. That is true, but the S2000's motor is so great, it is just so easy and encouraging to take it to redline all th etime. The engine sounds absolutely wonderful and it has this attitude like you are doing the "right thing" by revving the living daylights out of it.

Stitch said:

Huh? Vanos requires a totally different intake camshaft and vanos unit on the early models (and intake and exhaust since 1999?). It's not just something that's programmed.

I think you are all forgetting we're talking engines - not the cars they are in [shake] [:)]

Aluminium Engines

I am trying to point out the different between vanos and valvetronic. BWM makes excellent engines that we all know. Again I am emphasising valvetronic design to the ALUMINIUM ENGINES!!! sigH... Honda made aluminium engine a couple of years ago. Take a look at the list!!! You guys know what the difference between using Aluminium and cast iron? Let see how the new series Bimmer Aluminium engines perform.

Stitch said:

Valve tronic and vanos are totally different systems. Vanos is designed to allow a near-infinite adjustment of timing (within about 12 degrees), and valvetronic combined with vanos allows the valves to control the throttle along, obviously, with the timing of the engine.

Valvetronic is not used in the inline 6 engines, which is what wins all the awards.
