Filed under: Aftermarket , Videos , Chevrolet Click above to view the video Mated to a Corvette ZR1, the LS9 can get you from 0-60 in 3.3 seconds, and it will travel a quarter mile in 11.3 seconds. GM Performance Parts announced earlier in the week that beginning next fall, you won't need to own a ZR1 to get your hands on an LS9. The supercharged, 638-hp beast will be available as a crate engine to put under the hood of any project car that can handle the power. The GM Performance Parts team is so excited about the crate LS9 that it shot a video of the blown small block being hand-assembled. The clip shows some of the more significant parts of the LS9's production process, as well as some of the testing performed to ensure your crate engine is up to snuff. The guys building LS9s are lightning fast at their craft, too, and we're sure most gearheads would love to have some of the equipment they use during the build process. Hit the jump to see the moving pictures for yourself...

Filed under: Etc. , Plants/Manufacturing , Tech , Audi Audi is using American supercharging muscle to give its new 3.0 liter TFSI V6 the desired wallop. Eaton Corporation has been enlisted by Ingolstadt to supply positive-displacement, Roots-type blowers that will work with direct injection to deliver 290 horsepower and fat, responsive torque down low on the tach. Roots blowers aren't anything new, but Eaton has refined the design with its latest Twin Vortices Series units. The TVS units add a fourth lobe to the rotors, and crank up the twist to 160 degrees for maximizing the amount of atmosphere the blower can pump out. Jettisonning turbochargers may help packaging when the V6 is crammed into the S4's engine bay, as well as reducing complexity by simplifying intake plumbing. 310 lb/ft of torque at 2,500 rpm will put a grin on anyone's face, and we'd expect to see this engine proliferate into many Audi engine bays. Press Release after the jump. [Source: Eaton] Continue reading...

Filed under: Sedans/Saloons , Tech , Audi Automakers in the U.S. are just starting to truly embrace turbocharging , but Audi is going against that grain by choosing to supercharge its new 3.0L V6. We already told you some details about the new powerplant, and now we're hearing new specs from Autocar. The British website is reporting that the 3.0L V6 due to power the next S4 will be force-fed by an Eaton Supercharger to produce a power-output of 286 horsepower at 4,800 rpm and 310 lb-ft at 2,500 rpm. We'd heard earlier that the output of the supercharged 3.0L would be closer to 350 hp in the S4 and detuned to 290 hp for the mid-range A6, so this new report from Autocar has us a bit confused. We're assuming that the British outlet is just referring to the less powerful version of the engine that will power the A6 and doesn't yet know exact power figures for the S4 version. At least we're hoping so, since a less powerful S4 is no fun for anyone. [Source: Autocar ] Read...

Filed under: Sedans/Saloons , Cadillac , GM Click above for more high resolution shots of the 2009 Cadillac CTS-V When the Cadillac CTS-V and Corvette ZR1 were introduced in Detroit, they both had nice, round horsepower figures that look good in a press release. Last week, GM restated the output of the ZR1, raising it from 620 ponies to 638, which is an increase of about 3%. Cadillac admits that they didn't want to overstate the final horsepower figure for the CTS-V either, so we're likely to see a similar press release from GM's luxury division in the near future. Given the fact that the 550 hp figure for the top CTS was likely a lowball figure, Inside Line used the same 3% understatement from the ZR1 to peg the CTS-V's real horsepower number at 567. While Inside Line's 567-hp hypothesis was based on the fact that the CTS-V has the same basic engine as the ZR1, 567 is nothing more than a well-placed dart on the horsepower pinwheel. When we talked with GM's Ron Meegan...

Filed under: Videos , Supercars , Chevrolet , GM Click the photo above for pics of the ZR1 Corvette and its LS9 engine Yesterday we showed you an overview of the Corvette ZR1 's heart, the force-fed 6.2L LS9 small block V8. In naturally aspirated form, the LS3 powerplant hits in the base 2008 Corvette hits 436 horsepower, but the addition of a new four lobe Eaton supercharger lifts the ZR1 into the horsepower stratosphere. Ron Meegan, assistant chief of GM's small block engine program, took us through the ins and outs of the ZR1's efficient new supercharger and we had our cameras rolling. Hit the jump to learn how the Eaton supercharger works and what makes it special. We also attached a one-minute video that details some of the differences between the supercharged LS9 V8 in the ZR1 and Cadillac CTS-V.

Filed under: Videos , Supercars , Chevrolet , GM Click the image above for more high-res pics of the ZR1 The ZR1 Corvette is one serious piece of American metal, with the athleticism of a track star and the brute power of drag racer. While light weight materials, magnetic damping and 15.5-inch Brembo brakes sounds impressive, the real meat lies under the hood of the fastest ever production Corvette. GM's supercharged 6.2L small block V8 packs at least 620 hp and nearly 600 lb-ft of torque, and its duty is to finally put the Corvette into the supercar club. We were lucky enough to spend some time with Ron Meegan, the assistant chief of GM's small block engine program, and he gave us an engineer's view of the supercharged LS9 engine . Hit the jump to learn why GM didn't use the 7.0L V8 from the Z06, why the Eaton supercharger is so special, and whether or not GM is being modest with the ZR1's projected 620 hp rating.
