    So now does anyone still think the CTS-V will be 600 hp?

    After pretty solid confirmation that the ZR1 will be 620 hp?

    2009 Chevrolet Corvette ZR1 unveiled

    After years of speculation, spy photos, and rumors, General Motors has finally revealed its 2009 Chevrolet Corvette ZR1, which will be on display at the Detroit auto show in January. As expected, the ZR1 is the most powerful and most expensive Corvette model ever.

    An all-new LS9 motor produces 620 horsepower at 6500 rpm and 595 pound-feet of torque at 4000 rpm. Delivering 100 horsepower per liter, the supercharged 6.2-liter V8 is mated to a close-ratio six-speed manual gearbox with a new high-capacity clutch designed for the increased power. The twin-disc 260mm design provides plenty of clamping power, while maintaining a relatively easy clutch action.

    GM has not disclosed specific performance numbers, but the company admits a top speed of 200 mph is very likely. In terms of acceleration, the ZR1 will most definitely beat its Z06 counterpart, thanks to a 115-horsepower output advantage. Since the Z06 rockets to 60 mph in just 3.6 seconds, it's a safe bet the ZR1 will be much closer to the 3.0 mark. Final numbers will be announced in March 2008.

    Yeah...where is this coming from again? I've heard that's not from a well respected source...

    Re: So now does anyone still think the CTS-V will be 600 hp?

    The next V will be slightly over 500 but not 550hp.

    ~~~~~~~~~~~~~~

    PONTIAC, Mich. – When it arrives next summer, the 2009 Chevrolet Corvette ZR1 will be the most powerful and fastest production car ever produced by General Motors, with performance enabled by a new, supercharged 6.2L LS9 small-block V-8 engine.

    Incorporating the engineering experience already found in the Corvette Z06’s LS7 engine and the new-for-2008 6.2L LS3 of the Corvette, GM Powertain is targeting 100 horsepower per liter for the LS9, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (807 Nm); final SAE-certified power levels will be available in early March 2008.

    It is, indeed, the ultimate small-block engine for the ultimate Corvette.

    “When you experience the LS9 in the Corvette ZR1, the terms performance and refinement take on a new meaning,” said Tom Stephens, group vice president for GM Powertrain and Quality. “The LS9 demonstrates an outstanding performance range, with smooth driveability at low speeds, and surprisingly fierce performance when the customer wants more power.”

    The enabler of the LS9’s performance is a new, large positive-displacement Roots-type supercharger – with a unique four-lobe design – developed for the engine by Eaton. It is teamed with an integrated charge cooling system that reduces inlet air temperature for maximum performance. The LS9 represents the first of several new, supercharged small-block engines that will be introduced in GM vehicles in the near future, each using superchargers of similar design.

    “The small-block V-8 once again demonstrates it boundless horsepower potential, versatile design and an architecture with proven quality, durability and reliability,” said Stephens. “We haven’t yet realized the small-block’s performance potential.”

    Re: So now does anyone still think the CTS-V will be 600 hp?

    Never really thought it would be 600hp or more anyhow. My opinion is though that it could be within 50hp of this engine. I really think all three Supercharged engines are going to be north of 500hp being that the LS3 is ~430hp. My guess is that LS8 will be low 500's with LSA getting closer to the mid or more 500's and we now know LS9 is 620hp. The 620hp isn't SAE figure though and is probably conservative. I figure 625-635hp once SAE numbers are in on it.

    Right here.

    I have faith in Lutz. He promised a car that would suck the doors off the M5 with unexpectedly high power levels.

    With the current M5 coming in at 500hp, and having been around for a couple years, it'd be stupid for GM to build a heavy V with only low 500hp.

    Well the M5 is not a light car by any means. A 500-525hp Caddy with manual trans could probably suck its doors off.

    The key is hp/Liter. If you expect the ZR1 to come in around 100hp/L (S/C), then the Caddy will be under that, but only due to detuning since its going to be a similar small block in size. Again all you will need to do is turn up the boost and away you go.

    But the '08 CTS is already heavy. The V will probably weigh in even higher.

    Definitely, 600+BHP, with a pulley swap.

    No way it will be 600 stock, if the hand built LS9 is only going to be a touch over that hand built. But easily modifiable to 600? Sure.

    good luck gettin that pulley off. If its anything like the STS-v w/a completely integrated pulley assembly that you cannot remove, youre in for a bit of a wake up.

    Was not anticipating the pulley being integrated, I hope a vendor will figure a way to modify the boost. If not, still a great car that unmodded will kick arse. Was this done deliberately to stop modders, or done to make the unit more efficient/safer/better, etc... ???

    If it is not 600 I think it will be closer to 600 than 550.

    Re: So now does anyone still think the CTS-V will be 600 hp?

    They may lieave the intercoolers off the CTS-V and lower the hp from the 620+HP range to 550 hp or so.

    The LS9 in the Vette has the intercoolers and along with the supercharger assembly adds 100lbs to the front end.

    So the CTS-V will probably weigh an easy 4000lbs unless measures are taken to reduce front end weight thru aluminum or carbon fiber.

    Re: So now does anyone still think the CTS-V will be 600 hp?

    Horsepower is not what will get this beast going, torque is. My hope is that GM will deliver the same ZR1 motor with the nearly 600ft/lbs of torque and dial back the horsepower like they did with the GEN1 V's. They can keep the engine exactly the same for ease of production as a V will never run down a ZR1. There is some history here as our first GEN1's lost a few ponies supposedly to exhaust routing vs. the Z06's LS6.

    As far as beating the M5, that really won't be a problem. Sure it makes 507HP, but at a stratospheric 7,750 rpms. And it's torque is only 384ft/lbs again at a very high 6,100 rpms. The V's power curve will be broader, flatter, and certainly stronger and easier to maintain vs. trying to keep the revs up in the M5. The M5 weighs 4,050 lbs. so it's a porker as well. Now for Lutz's dream to become a reality here's the performance benchmarks they'll have to hit:

    0-60mph = 4.1 seconds
    0-100mph = 9.5 seconds
    1/4 mile: 12.4 sec@116
    Top Speed = 155mph (limited)
    Lateral G's = .87g
    Braking 60-0mph = 120 ft.

    Let's take these one by one.

    Acceleration is about launching. Launching is about torque and traction. If GM fixes the rear diff, as in stronger with no wheel hop they're nearly there already with 400hp. Let's face it, if you could power launch the current V you'd be hitting 12.8's in the 1/4 already. 12.4's are easily within reach with another 100hp+ and 100ft/lbs+.

    Top Speed - GM has shown no predisposition to top speed limiting it's vehicles. I doubt highly that they'll start with the CTS-V. Get ready for 185mph+ easy. (If a 425hp Chrysler can hit 174mph, the new V's got to be good for 190mph)

    Handling has always been a strong point of the V. .90g's are merely a good set of tires away. I bet the new CTS-V gets an even better suspension (if that's possible), maybe something derived from their SCCA Championships and the new revised Goodyear F1.

    Braking - The current brakes are already stellar, needing only 118ft. to stop from 60'. I'd bet here too that Brembo has an upgrade and don't underestimate what a great tire can do here as well. With the heavier car, the braking distance will stay at 118'.

    If you're looking for the test mule to all this power, chassis tuning, component testing prior to the CTS-V.........read this link.
