ah, the other shoe drops on "Blue Devil"/"Corvette SS", whatever the else they are calling the "super vette"

[Fredo]

sucks that there is a pic of the intercooler, but not of the screw setup. Must be something fairly interesting looking at how short the blower is compared to the intercooler.

prolly just a twin screw whipple type. whats cool is that its in the lifter valley under the intercooler.

[Seth]

Interesting. Looks very leak/blowout prone.

[Fredo]

yeah, I always thought that was odd that ford slapped the intercooler in the lifter valley. I'm betting your right that it just sits low inside the valley, didn't really think about it that way from looking at the way the pic was taken.

[agjohn02]

the northstar in the xlr has the intercooler under the blower, similar setup but reversed. what do you think, 600 hp?

[Fredo]

well, a bone stock 5.3 with an intercooled radix kit makes like 425-450, so I'm betting 600-650 isn't at all out of the question. The better question is how much more power will a set of full length headers and a different pulley make? :)

[agjohn02]

600hp is conservative for what that combo could make. Mast is making 540ish hp out of that same basic engine, NA. they probably be putting out 1000hp when they get some of these LS9 set-ups next year.

here is their newest 427, non VVT, LS3 dyno chart. i guess they just forgot to take the VVT off of the chart title.

Hey look its a 6.2L :flipoff2:

This reminded me of the new GM diesel. I couldnt find the article to scan it until just now.

GM's surprising new diesel has no manifolds

General Motors recently took some of the wraps off of its 2010 Duramax diesel V8, revealing clever design features and technologies that clearly push the state-of-the-art in Vee-type compression-ignition engines.
Unveiled during a media briefing at its Milford, Ml, Proving Grounds, the new 4.5-L powerplant will be one of the most powerful, lowest-emitting, and package-efficient light-duty V8 diesels in the marketplace, company engineers claimed.
The new Duramax is scheduled to enter production in late 2009 at GM's Tonawanda, NY, engine plant. It will power GM's full-size pickup trucks and utilities, among other potential applications.

Rated output is targeted at more than 310 hp (231 kW), for 68 hp/L (51 kW/L), and 520lb-ft(705N-m).
The Duramax was designed to fit within the ultra-compact envelope of GM's small-block gasoline V8. Its NVH profile also targets the gas engine. These aggressive requirements drove many of the engine's innovations announced to date.
The new engine's aluminum cylinder heads' exhaust ports face inboard, toward the valley of the cylinder block. This allows the single variable-geometry tur-bocharger, exhaust-gas recirculation (EGR) cooler, and close-coupled oxidation catalyst to reside within the valley. The layout negates the need for separate exhaust manifolds while reducing overall width.
The reversed-head orientation also means the new diesel does not use a conventional intake manifold. Its intake ports are internal, rather than arrayed along an exterior face of the head as in common practice. The ports are fed pressurized charge directly through the tops of the intake camshaft covers.
The heads' unique two-tiered internal construction segregates the intake route, the chain-driven DOHC valvegear, and water jacket. (The fully dressed engine on display was not sectioned, so no internal details were revealed.)
Compacted graphite-iron (CGI) optimizes the cylinder block's strength and mass. The block's cylinder banks are splayed at 72° to achieve a narrow overall package with even firing, but the narrow vee requires a balance shaft for smooth running. GM studied aluminum block castings but determined that the light alloy would not deliver sufficient long-term durability and could not cope with the cylinder pressures planned for the new engine.


Right side of the new V8 shows lack of exhaust manifold. Intake route is straight into the top of the intake cam boxes.
Chief Engineer Gary Arvan (left) and GM Diesel Engineering Director Charlie Freese with their latest baby at Milford.

Cast-aluminum intake plumbing on the current prototype engine may be superceded by reinforced plastic before the program reaches production. The ultra-compact diesel V8 has its turbocharger hidden between the cylinder banks.

That is gonna rock some Bubba mechanic's worlds, as if the new diesels hadn't already.

Hey look its a 6.2L :flipoff2:

just because its well-dressed, don't automatically assume it's gay :flipoff2:

[Graystroke]

I wonder how serviceble it is? what happens when you get an exhaust leak...by the looks of the pic it would be several hours to just get to the problem. Cool ideas...almost seems like a design excersise that is being produced which many times may not be practical.


I still can't figure out why someone can not produce a 180-200 hp diesel for sport utes small trucks that will give you 25+ mpg.
Whats the point of having a 310 hp diesel that gets 18 mpg(inflated...I doubt it would get that in a burb) @$3.40 gal w/ a probably $4k+ (I would guess $5K maybe more) buy in premium when you can get a 5.3, 6.0, 8.1 that get 16, 12, 12 mpg @ $2.80 gal w/ around a $1000 buy in premium for the 8.1. I know some will say the 520 ft/lbs of torque..well the 8.1 has what, 480 ft/lbs? and will probaly cost $4k less.
operating cost:
fuel only
Gas $2.80 @ 12 mpg= $0.233/mile
Diesel $3.40 @ 18 mpg = $0.19/mile...again I doubt it will get that..friend of mine has an '06 Dmax that gets 13.5 mpg
$4k initial cost diff $1k for the 8.1 $5k diesel =$4k
100,000 miles of driving before you break even. I know diesels have a higher resale. but gas trucks really don't drop that much before a 100,000k so you get about the same percentage drop in resale...especially if it is an HD.
what is the D-max now? a $7k option?
other downsides: a diesel is a lot more expensive to repair. oil changes are expensive, fuel filters and fuel quality has to be closely monitored
I like them, wish I could afford a new one and wish Diesel didn't cost so much. I bet the new burbs are 60k+ w/ the diesel maybe even pushing $70k. I'll keep the quadrasteer a couple of more years and do donuts around them until one comes up used.

did you steal chadnutz math book :flipoff2:

toyota has the small motor you speak of but doesnt sell it in the us, jeep had it for a couple years (i think) but doesnt loook like its in the line-up anymore.

[Graystroke]

I know yota has one...and what are they going to put in the tundra? some big cat motor? right? (a rumor a few years ago) or do they have their own now? everybody has to one up the other guy.
anyways, why can't they make small diesels for 1/2 ton p/u like little +/-3.0L straight 6's.
same for suv's.
LR 300TDI 111 hp diesel gets over 30 mpg in a barn door aerodynamic defender. hp Isuzu 4BD1T (4cyl in cab forward Isuzu box trucks you see everywhere) 110-130 hp. can move 10k no problem...if you ever been behind/next to one then you know they are not slow. One of those transplanted in a small truck return 25-28 mpg.
I guess when gas sees $4/gal we will see more

wont increased diesel vehicles on the road = increased demand for diesel = higher diesel prices since from what i've gathered we havent increased refining capacity for diesel in quite a while, and not all refineries can produce ULS diesel. (this is more of a question, than a statement of fact)

[Graystroke]

oh, I'm sure it will, they will find a way to justify higher cost...I wonder what the gallons sold was say in 1990 vs today? when dieslewas less than reg. gas. I guess the oil companies have increased gas refining cap and not diesel...funny, I thought they all came from the same place. Doesn't everything petroleum related come off the same cracking tower? fuels up top, asphalts bottom? maybe it's the secondary processes that hold it up.

[Graystroke]

the oil companies are fawking us! according to this diesel and gasoline come out of the same tube! mother fawkers! :flipoff2: :flipoff2:

I think that saying diesel is that much more expensive than gas is not entirely accurate. I don't watch closely, but it seems that diesel is lower than gas at times as well. They each have ups and downs, but just at different times.

diesel fluctuates less than gas in general, down in the summer, up in the winter for heating oil. The trend is essentially gone now as the oil companies are sticking to anybody and everybody citing the cliche' reason of the week.

I have an idea, nobody buy gas on tuesday, send this idea to all your friends, I'm going to start an email forward! we'll get those ****ers!

[CheapJeep]

I wonder if they'll still have another 6.6L Duramax version for the HD's. I read that the current LMM 6.6L Duramax is an "interim" model (365hp/660lbft) and that they have something "bigger and better" in the works. I couldn't imagine them only offering the 4.5L which would be directed towards 1/2 tons and maybe as a smaller diesel engine option in 3/4 tons. Kind of like the 6.0 to the 8.1 gassers (they don't offer the 8.1 anymore?).

i paid $.69 at this little raghead gas station on 1314 in '99, no credit card machine, cash only, later i stopped there in samantha's car and filled up and the car ran like sh!t for the entire tank, but my bronco burned through it so fast im pretty sure i could have filled up with diesel and it wouldnt have cared. :gigem:

Cool info. I guess the only time diesel is lower it appears, is when gas takes off. Diesel then takes a little while to catch up. Convinces me even more that a gas half ton is the way to go.

It won't be long before there is some pretty good bio-diesel production being made. As long as the folks that own the factories can keep from getting greedy and selling out to the oil comp's and don't mind taking a big risk investing a **** pot full of money, then it will be fine.

I think I will start making my own when I get home. Especially if I am running a fuel guzzling dozer. It might not be good for my waistline though, w/ the smell of popcorn coming out of the stack all day. :D

CHEVROLET ANNOUCES CERTIFIED POWER RATINGS FOR THE NEW CHEVROLET CORVETTE ZR1: 638 HP FROM THE SUPERCHARGED LS9 V-8

http://www.blogsmithmedia.com/www.autoblog.com/media/2007/12/x09pt_ar001.jpg


PONTIAC, Mich. – When it was introduced at the North American International Auto Show in Detroit earlier this year, the 2009 Chevrolet Corvette ZR1's power was estimated at 100 horsepower for each of its 6.2 liters of displacement. GM Powertrain has completed SAE certification of the ZR1's supercharged LS9 V-8 and the results exceed the estimate: 638 horsepower (476 kW) and 604 lb.-ft. of torque (819 Nm).

The LS9's output is nearly 103 horses per liter, or just about 1.7 horses for each of the engine's 376 cubic inches. It is unquestionably the most powerful automotive production engine ever manufactured by General Motors and enables the Corvette ZR1 to achieve a top speed of more than 200 mph (322 km/h).

"One of the most amazing things about the Corvette ZR1 is the level of refinement that our designers and engineers have attained. Even with all that power, this car has road manners that will allow our customers to enjoy it on the streets as a daily driver, and on the track," said Chevrolet General Manager Ed Peper.

The Corvette ZR1 goes on sale this summer. Its 638-hp supercharged engine is complemented in the chassis by heavy-duty components not offered in any other model, including a six-speed manual transmission with race-hardened gears and dual-disc clutch technology that delivers exceptional clamping power and lower inertia, as well as strengthened axle components.

Fuel economy testing has not been completed, but engineers are confident the ZR1 will be the most fuel-efficient 600-plus-horsepower car on the market.

The LS9 engine is hand-built by specially trained technicians at GM's Performance Build Center in Wixom, Mich. It is a unique, small-volume engine production facility that also builds the Chevrolet Corvette Z06's LS7 engine and other high-performance GM production engines.

"Developing the LS9 involved more than simply striving for a great horsepower number. Endurance and reliability testing have shown the engine to be robust and low-maintenance, just like other engines in the small-block family," said Sam Winegarden, executive director, engine engineering for GM Powertrain. "That it is distinguished as the most powerful engine ever from General Motors is a source of immense pride among everyone involved with the LS9."

Supercharged aspiration

The key enabler of the LS9's performance is the industry's first production application of a new, positive-displacement Roots-type supercharger that has a unique four-lobe rotor design. Its design promotes quieter and more efficient performance, while the large, 2.3-liter displacement ensures adequate air volume at high rpm. Maximum boost pressure is 10.5 psi (0.72 bar). It is teamed with an integrated charge cooling system that reduces inlet air temperature for maximum performance.

"The combination of large displacement and the new, four-rotor design broadens the effective range of the supercharger, allowing the engine to make more power at lower rpm and sustain it throughout the power band," said Winegarden. "The low-end torque is tremendous and the high-rpm charge from the supercharger is simply amazing."

A raised hood provides adequate clearance for the LS9, while a polycarbonate window in the hood provides a view of the engine beneath it.

LS9 details

The LS9 features many unique design and manufacturing details that support its high-performance nature. They include:

Aluminum cylinder block with iron cylinder liners that are finish-bored and honed with a deck plate installed
Forged steel crankshaft with a nine-bolt flange
Titanium connecting rods and forged aluminum pistons
Stronger, rotocast cylinder heads with 2.16-inch (55 mm) titanium intake valves and 1.59-inch (40.4 mm) hollow-stem, sodium-filled exhaust valves
Camshaft with 0.555-inch (14.1 mm) lift for excellent idle and low-speed driving qualities
A dry-sump oiling system with 10.5-quart (9.9 liters) capacity
Integrated oil cooler and piston-cooling oil squirters

I know many of you are interested in the latest details on the new Corvette ZR1. We’ve been working on the car for a while now and recently, we decided to put the pedal to the metal and see just how fast it could go.

On a cool day with light wind in early April, the Corvette Development Engineering team took it to the test track in Papenburg, Germany. The ZR1, with its 638 horsepower supercharged LS9 V-8 engine, clocked in at a staggering 205 miles an hour (330 km/h). We’re thrilled with the results and excited for it to hit the streets. We even brought a camera along for the ride to document our experience. Check out the video posted above.

That's fast.

[BMFScout]

The 956 has a place for a license plate? Would hardly classify it in the same category as a vette.

[bburris]

I saw an Audi R8 in Frisco yesterday, nice looking car.

[Fredo]

Did anybody click on the other article links. the lap time one...It has other cars and their lap times. fastest ever was the Porsche 959. did it in 6min 11 sec! The article stated what's even more amazing is that it was done 25 yrs ago.
.

Something tells me that article isn't exactly accurate. If a 959 did it that fast, it sure as **** wasn't the "road version". This car did it in 6:55.

EDIT: I just realized that Grayson put 959 when they were talking about a 956. BIG difference! I can't see the videos here at work so I didn't know until I started reading the comments below the article. Still though, that's not even a fair comparison.

[Graystroke]

oops, I was thinking 959 not 956. wasn't comparing. just stating.
ya'll don't need to get your LS based GM panties in a wad!:flipoff2:

[BMFScout]

Whatever, it's too close to the 4th for you to be even talking about other countries! America...FAWK YEAH!!

[Fredo]

hehe, no, I wasn't getting them in a wad. It just sounded like you weren't impressed that a bone stock ZR1 that carries a 3yr/36000 warranty is that f'n fast.

Don't get me wrong, I love the looks of a 956...those things were evil. Short lived career, but evil none the less.

[Fredo]

Speaking of short lived....this is definitely one of my favorite "what could have been" race cars. The Jaguar XJ13.

a ZR1 isn't really a Vette either by that logic, they are both tuned production models.

[BMFScout]

I bet they make more than 150 ZR1's.

[Fredo]

I think I read something like 1500-2000 a year.

[Jackasic]

holy crap, they are going to build 2000 a year?

[Fredo]

They averaged about 1400 per year in the 5 year run of the old ZR1's. 6939 total in 5 years.

That's stupidfast.

Fixed it.

[Jackasic]

i was getting a little confused when Jimmy switch to a 956, I was thinking 959. Other thing to bear in mind is that was 25 years ago, what is the comparable P car time now? I have no idea, just throwing that out there. I love the performance of the vettes, but I am with Clarkson on the fit and finish. You still have to drive it everyday, for that money I don't want to see a GM truck radio.

Don't go quoting wiki like it's fact. Please notice the NOTES section to the right.

[Jackasic]

don't get in a tither, i just post the first list I found, heck that one doesn't even have a 959 on it.

[Fredo]

I'm not in a tither...I just can't believe you of anyone would believe wikipedia to be accurate. :)

[Jackasic]

it's close, thats about all we need here ;) We all know that VW's are the best cars EVER!!!111!!!!11!!!!

don't forget that the gearbox is rubbish and that the bumpers are plastic.

[Jackasic]

I'll definitely agree with the latter and I can see where he comes up with the former after riding in a few nice cars.

[Jackasic]

this may count as porn for Fred: http://videos.streetfire.net/video/2009-Corvette-ZR1-LS9_168134.htm

[rockfrawg]

they put that whole engine together in 6 minutes!! dayum!

[Fredo]

Nah, that Jag I posted does make me feel funny in the swimsuit area, but watching them assemble that motor, not so much. I do really like how they torque the headbolts on LS motors though.

[RCcola55]

May be a R, but saw on barrett jackson last night that the first production ZR1 sold for a mil

whats with the 177 top speed? he near redlines it in 5th at 175, shifts to 6th and it hardly pulls.

[Fredo]

They say there was a wicked headwind they were fighting that day according the article I read on it. I think that was on jalopnik. From the massive increase in wind noise and how the car doesn't pull 6th I would believe it because it doesn't have any problem pulling 6th in that other video where they take it up over 200. I could also see that guy deciding 177 was fast enough on that rough ass track in a car on street tires.

i bet the phat bonus GM said they'd give him for breaking the record kept those thoughts at bay. i think it was about 6:10 when you see him get the car all out of shape and throw his hands in the air. he was thinking, "crap there goes the bonus."
