I guess this is a confirmation?

SWEET! 10-15% horsepower increase is substantial!

 

There are some surprises in store for the 2-valve (small-block V-8). And we're not talking about 10 or 15 hp.

Sounds like variable cam timing :cheers:

 

WOW!!! That is cool, Good find. :thumbs:

 

Good one!!! :thumbs:

 

Thank you for posting. How do you find all these things? :cool:

 

Most of what I find is by searching with GOOGLE. Aside from that,
find industry media on the web that cater to the industry rather
than the consumer. They'll be more informative and more accurate.

1) US patent & trade office ( http://www.uspto.gov/patft/index.html )
____ Notice that the green rectangle is for Issued patents while
____ the yellow is only for ones that have not yet been issued.
____ Use the quick search and type in things like "internal combustion"
____ in field 1 and set that to Abstract. In field 2, try "general motors
____ corporation" associated with Assignee Name and then hit search and
____ wait awhile. What you'll see is
____ ABST/"internal combustion" AND AN/"general motors corporation"
____ To narrow this if you're looking for 3V engine stuff, maybe try
____ ABST/"internal combustion" AND AN/"general motors corporation" AND ABST/valve
____ Once you've found something interesting, look for who this guy/gal
____ cites and then who has cited him or her. Practice makes perfect.
2) SAE website ( http://www.sae.org/servlets/index )
____ Use the search tool at the upper left-hand-side to type in
____ things like " direct injection AND gasoline " but without the
____ quotes. Logical words like AND and OR must be capitalized. Also, try words
____ like corvette or LS1.

3) Magazines:
http://www.autonews.com/ http://www.ai-online.com/ http://www.sae.org/automag/ http://waw.wardsauto.com/
http://www.autoweek.com/ http://www.motortrend.com/ http://www.roadandtrack.com/ http://www.caranddriver.com/


4) GOOGLE ( http://www.google.com )

Let's say we want to learn about the new GM six speed automatic transmissions.
Try typing in (quotes mean the words must appear contiguously)

"six speed" automatic transmission GM -ZF
"6 speed" automatic transmission GM -ZF

The -ZF is to remove hits about the new ZF transmissions. Since we know
that we only want rear drive cases, try

"six speed" "automatic transmission" GM -ZF rear
"6 speed" "automatic transmission" GM -ZF rear

Since they are likely to show up in 2005, try

"six speed" "automatic transmission" GM -ZF rear 2005
"6 speed" "automatic transmission" GM -ZF rear 2005

Also, since we know that prototypes were called the X13R, X14R,
X15R, and X16R - try those

X15R GM

When I wanted to learn about future GM DI engines, I wanted serious
documents like pdf files. I also guessed the engines might come on
line in 2006 or 2007 once the sulfur was out of the gasoline.

GM DI V8 2006 filetype:pdf
"direct injection" gasoline GM

You can also play around with

"variable thickness" hydroformed aluminum
SAE hydroformed aluminum

 

Did you recognize the name "Alan Hayman?" He's the owner of
a few patents that you might recognize:

6,601,557
6,505,592
6,505,591
6,505,589
5,560,329
