BorgWarner Launches Breakthrough VCT Technology for New Family of GM V6 Engines

AUBURN HILLS, Mich., Feb. 16 /PRNewswire-FirstCall/ -- BorgWarner Morse
TEC has begun production of its first high-volume variable cam timing (VCT)
systems for a new family of General Motors V6 engines being introduced this
year. This system uses a Torsional Assist(TM) technology instead of the
conventional oil-pressure actuated approach. The new technology is beneficial
for both overhead valve and overhead cam engines, and represents a leap to the
next generation of cam phasing. The launch is BorgWarner's first production
of its VCT technology and constitutes a major step in the expansion of
BorgWarner's growing engine management business.
"This production launch is a milestone that has been years in the making,
and reflects a breakthrough that will revolutionize the use of variable cam
timing," said Roger Wood, President and General Manager, BorgWarner Morse TEC.
"VCT is a natural extension of our global capability in the fixed timing drive
market. We are delighted to provide GM, and the drivers of vehicles equipped
with these new engines, with improved fuel economy, reduced emissions and
enhanced performance." These new sophisticated V-6 engines, which include
3.5L and 3.9L variants, are the first mass-produced overhead valve engines to
feature cam phasing in an overhead-valve engine design. Later this year, the
new 3.5L and 3.9L V-6 engines will debut in the 2006 model year Chevrolet
Impala, Chevrolet Monte Carlo, and Pontiac G6.
Variable cam timing is a means of precisely controlling the flow of air
into and out of an engine by allowing the camshaft to be dynamically phased
relative to its crankshaft. BorgWarner VCT technology includes devices that
utilize camshaft torque as their actuation energy, in contrast to conventional
phaser devices that depend on engine oil pressure for actuation.
"The Torsional Assist innovation that BorgWarner is providing to GM is
unique to the industry," Wood said. "It requires fewer engine architecture
changes and yields fuel and emissions benefits greater than conventional oil-
pressure actuated devices. This launch is another example of how BorgWarner
is exceptionally positioned to engineer, manage and supply completely
integrated variable cam timing systems."
Camshaft phasing technology is rapidly becoming a standard in the global
engine market. The worldwide market that will utilize this technology is
expected to grow 500 percent from 2000 figures of 5.2 million engines, to over
26 million engines by 2009.

Good catch, nade (may I call you nade?).

I didn't know this kind of thing was outsourced by GM. I really hope they have this thing down and it proves very reliable from day 1.

BTW, that is quite a paragraph of legal fine print at the bottom of this release!

Whats the point? The 3.5 push rod motor is way behind the leaders in NVH and refinement.

Maybe the point is that the VCT will improve that, Duh!

Now maybe GM can team up with Barry Grant who has designed a 3 valve head for the LS family and have him do a 3 valve head where it is needed most, on the above mentioned engines.

[BigAls87Z28]

First, the 3v head GM has already done
Second, the 3v head is for Gen I small blocks

This is very cool! Glad to see the 3.5 also getting this, Hopfuly this will add more hp across the band.

What about a new V8 family? Or maybe a new HYDROGEN family?

HAHA no kidding. I would like to see a rundown of how many V8's vs V6's GM sells. I.m sure their trucks make up a large % of the V8's but man I wish they would spend a little more time on their V6's. I know 3 valve heads have been done but so have VVT DOD and many other things. I just wish GM would do the 3 valve heads to help out their V6's that are in so many cars. I would rather have a 3 valve 3.9 that makes a loafing 280hp to a smooth and quiet one that makes 200hp.

[sncrducrx]

I just Hope it's Compatible with the 3 valve heads and DOD.

Adding the 3 valve heads to the 3.5 should up the HP to about 240. This Hopefully would add enough power to make DOD viable in the 3.5.

Amen. What in the hell is wrong with these freaks that think that the only way is OHC?

I hate puppets.

[Cortazzo]

This is an exciting announcement, I'm looking forward to seeing the power and efficiency gains. If this technology works will in the v6s, perhaps they could put it in their v8s as well???

[DemonKnightDK]

...what about that 6speed GM was making with Ford? where the hell is that at? why out source when you have one in house? (that you just made...) or is borgwarner owned partially by GM?

[Codester66]

does anyone here think a 3100/3400 to a 3.5/3.9 vvt swap would be too difficult? i would love to see a couple older(more affordable)cars with a bigger v-6 inplace. obviously some computer work and a different tranny, but what else? if GM made it easy to convert, they could have a potential aftermarket considering all the fwd v6s out their. hopefully there will be some parts available for these engines, like headers and other hard to find GM aftermarket v-6 mods

[mrfunji]

This press realease sounds more like a commercial for Borg Warner.

[Butz]

It isn't GM execlusive, so other carmakers will have it too..
