V-tec

[NSX-TSION7]

Brand spanking new to the Family as of this past Saturday. Its great! Question, what is the V-TEC? And what can I run up against. I am stock 290 right now so any comments would be helpful. I don't have an Owner's Manual either.

Now that was the coolest! I appreciate that. I have something to talk about now. Thanks again.

Congratulations!

Spend some time with the NSX FAQ (answers to Frequently Asked Questions). You can access it by clicking the word FAQ in the red bar at the top of your screen.

what can I run up against.

You can run up against vigorous law enforcement in such a conspicuous car. Take it to the track and run against whoever else shows up.

I don't have an Owner's Manual either.

You can buy one here.

 

[NSXCELERATE]

man, you are going to keep getting amazed by the engineering that goes into these cars. The FAQ will teach you a whole lot. I just happened to get 2 books with my car that cover all of the technology. NSX is hand assembled, each one is also tested on a track before it leaves japan! thats just a sample, lol I just got my car Tues.

Did you guys see what Honda did with the 05 Odessey's with the I - Vtec engine. It is set up so you only use 3 cyclinders instead of all4 when you are just doing city driving..... Sweet. Makes it cheaper on the old pocket book when buying gas.... I wonder if they will all go that way over the next few years??????

Mercedes S600 v12 runs on 6 cylnders while cruising and all 12 kick in when you need it. Its been around for a few years now.

Ya I know, But I wonder about Honda??

Talk about "a few years"... Cadillac had this function in 1981, in their V-8-6-4 engine. As described in Edmunds:

Infamy came in 1981 with the introduction of the V-8-6-4 variable displacement V8. Based on the 6.0-liter Cadillac V8, the V-8-6-4 theory was that individual cylinders would be electronically shut down as engine loads varied; a V8 for acceleration, a V6 for moderate loads and a V4 during cruise. It would have been nice — if it had worked. Instead, it was a mechanical nightmare only slightly less embarrassing than the ongoing diesel debacle.

Alfa Romeo had this system already in the 70s (you remember these famous Alfasuds that went rusty already in the brochures?). It used to cut off 4 of 4 cylinders when you least expected it which lead to zero fuel consumption and zero mph. And the best thing: Not even the Alfa engineers knew about this system :biggrin:

Some say it was also used in some former Ferraris....

If you read Edmunds' 550 Maranello long-term test reports, you can see that this 12 cylinder cutoff fuel saver mechanism is still in use in modern Ferraris as well.

The NSX engine is so understressed at 290hp that it's baffling. A higher compression ratio and the RL variable exhaust, the Type-S intake runner stuff from the TL, and the other little tweaks Honda has added to their other engines over the years would have this plant at 320-340hp. Or, they could have added displacement like everyone else has been doing.

And let's not forget the British and all those jokes about Lucas electrical systems!

Holy crap! GM actually came up with something creative!? :wink:

Now be fair. GM has come up with a lot of great ideas that have failed.

be nice now.... I cut my teath on F bodys and stand beside them.

Dodge is using that technology on the new Hemis also.

i may be off but didnt GM attempt rotary at some point in history?

I believe you are correct. GM developed the rotoray engine, but sold the design to Mazda because they did not believe it had potential due to high fuel consumption. I also believe that GM developed fuel injection, but sold the design to Bosch, believing it was a dead end. 10 years later nearly every German car had k jetronic fuel injection. Perhaps GM's biggest problem was their vision. :smile:

I hope you don't speak of the invention of these things - both where german - rotary engine by Felix Wankel, first used in a NSU in the 60s, not in a GM car. The fuel injection was first used in german warplanes during WW II.

Not at all. That is why I use non-committal weasel words like I believe and develop. LOL

But seriously I had thought that GM had sold the fuel injection system to Bosch, which they developed into the k jetronic. If that isn't so please let me know as I have been misinformed.

 

[NSX-Racer]

According to this source you've mixed up two things:
In 1980 GM invented the central controlled injection system Multec. That was long after the K and L jetronic by Bosch.
But: Mr. Bendix (USA) developped an injection system with pressure measurement in 1967 for the Volkswagen 1600 E which was later used by Bosch as the first jetronic (better known as D jetronic).

OTOH it is more than likely that the first engine with fuel injection was a stationary engine in 1884 invented by the german Johannes Spiel.
In 1925 the americans Bendix and Stromberg developped a new kind of carburetor with additional fuel injection for plane engines (isn't that still called the Stromberg carburetor?).

So both sides of the pond have invented their share but the part of GM is very small.

:redface: Cool. thanks for getting me straight on that.
