Added pressure makes for a Z-oh!-6

The C6 Z06 clubs nearly everything in its path. With 505 horsepower produced from a hand-assembled 7.0-liter LS7 V-8, the Z06 easily outpaces the mighty 8.3-liter Viper SRT-10 Coupe-which has made the Dodge boys quite angry. In response, SRT will soon release its super-strength 2008 Viper shod with a new 8.4-liter V-10 that cranks out 600 hellspawned horses. The gloves are off and the fight is on.

Rather than being outgunned by Mopar, Z06 owners can now gear up with more power thanks to a booster shot of bolt-on performance from Vortech Engineering. Known for making big top-end power, Vortech produces a variety of centrifugal superchargers that cram heaping helpings of added oxygen into an engine for impressive power gains. In the case of the new Z06, Vortech has just put the final touches on a kit featuring its latest V-2 SQ T-trim centrifugal supercharger, which delivers 6 psi of boost to the LS7 V-8. The SQ design stands for "Super Quiet." Gone is the obnoxiously loud gear whine associated with most centrifugal superchargers. Rather, at idle and cruise speeds, the blower is nearly silent-so as not to give away your forced-induction secret.

The Vortech kit ($6695, satin finish; $6995, polished finish) offers everything needed for installation, including a T-trim supercharger, air-to-air aluminum intercooler, compressor bypass valve, aluminum mounting brackets and hardware, high-flow fuel pump, oversize fuel injectors, and even a specially programmed Diablo Sports handheld programmer to reflash the factory computer with the proper spark/fuel calibrations. The result is an LS7 engine that cranks out a dyno-proven 635 horses (35 more than the upcoming 8.4-liter Viper's), while sipping 91-octane pump fuel. In addition, the 50-state smog-legal kit is optionally available with a three-year/36,000-mile powertrain warranty through Vortech's network of top-tier installers and new-car dealers.

Enough tech talk, how does the Vortech kit perform? The answer is simple: too well. Fit to a bone-stock Z06 (tires, exhaust, suspension, etc.), the output is so substantial the car has a hard time taking off. Laughable amounts of rear tirespin occur in first gear, even with part throttle application. In fact, our best quarter-mile launch resulted when bogging the V-8 off the line at 1400 rpm and then short-shifting the 1-2 shift at 4400 rpm-before big boost hit. In second gear, the stock Goodyear Eagle F1 325/30ZR19 tires puts down thick black stripes on the tarmac as the Z06 fishtails wildly. By third gear, you can apply full throttle, wind to the 7000-rpm redline, then watch the speedometer digits count up faster than a Chinese mathematician working a nitrous-fed abacus.

At the end of the quarter mile, the Vortech Z06 runs just a few tenths quicker than a stock Z06 (due to wild tirespin), but delivers a nearly 10 mph more trap speed (a more accurate indicator of the power increase). With stickier tires, a Vortech-blown Z06 should run in the 10s. Rejoice knowing a Vortech Z06, even with copious tirespin, will still go 0 to 100 to 0 mph in a scant 11.7 seconds. Take that, Mr. 8.4-liter Viper.

That's pretty cool but it further strengthens my belief that the new 650hp Z07, Blue Devil, SS or whatever it will be called is just too much. I think the current Z06 has all the power a street car should ever have.

For the C7, they should focus on the interior and chassis. If they bump the horsepower up to 525 or even 550, I think that would be all that the Corvette needs. Oh, and how about a seven speed sequential manual for the C7 to go with the 7.0 liter V8?
 
I thought I read the next vette would be a V10? I might be wrong. But yea, I with you. They should focuse on handling.
 
lol, .2 seconds but 9mph :) hell of a car, i think i'd get in too much trouble with it though and probably crash due to lack of traction
 
Things are just getting downright crazy now! Sweet ride though. With no current arms race everyone is trying to figure out how they can best the next man...LOL.

Isn't it crazy that 135 more horsepower only gets .2 better in the 1/4 mile for 7 grand not including installation. Crazy, but I guess if you can afford a Z06 another 7 grand ain't s*** right?
 
if they keep this up, there going to have to start enforcing driving school just to buy a Z06, Viper or GT500.
 
Hmmm...These are the sort of specs I would like my project car to have...Ohh...I've said to much!...more on that later ;)...I can never say no to a Z06 R-E-S-P-E-C-T! :D

I'd imagine with better tires and a dialed launch you'd see much better gains than just .2
 
yeah check out the 0-60 times... couple that with the trap speed and its an obvious traction problem.

throw some 11" wide grippy tires, and Im sure times would improve a ton.

Like the others said. .2 better in the 1/4 mile and no traction in the first to gears is just badass!
 
i agree re: the C7. i'd like to see a better "car" and even less weight.

you're focusing too much on times. 9 mph in the quarter mile is a huge gain (esp at those speeds). trap speed is a much better indicator of power than ET is.
