i have a couple questions, and i was told to post over here.. i searched around on here but really having seen any 1/4 times of RWHP numbers out of a LS3 standard 580 Callaway package..
i think i'm going to go this route due to the cost of the base LS3 Z51 M6 i can get, and the package price of the Callaway with the warrenty of 100K powertrain on their equipment..
well first, does anyone know what a standard 580hp package vette pulls on a dyno? i saw that Callaway is stating 10.9 in the 1/4 on their web site with a M6, but i want to hear about the real world numbers..
Second.. i know that this package includes their cold air intake and DD cat pack system but what type of power do you think i would pick up with headers and high flow cats? and a new tune too..
My (LS2) Lingenfelter Pkg makes 505 hp at the rear wheels, that's about 600 engine hp on my A6 car. I would expect your LS3 Pkg to be 500+ rwhp also. The stock LS2 pkgs (Callaway and LPE) were making around 460-470 rwhp....stock manifolds, stock pulley. I would expect the same pkg on your LS3 to be 30hp (or more ) stronger. As far as modifying Callaways stock pkg, they're probably not going to like it and maybe won't warranty it. Headers won't make much of a hp increase (10 rwhp is what I gained)....you will see a big torque increase though (I gained 32 ft lbs). You will also lose 1+ lb of boost with the headers. You will need to change to a smaller pulley to compensate (that alone might void Callaways warranty). There's not many of these that are run down the 1/4 mile....these cars are too traction limited. I think their 10.9 is conservative (if you could put it to the ground) ....with street tires, you wouldn't come close to that. I have seen a LS2 Lingenfelter Pkg (similar to mine) run a high 10 @128mph (on slicks) before it destroyed the rear differential.
I guess what I'm trying to say is: I would expect the stock LS3 Pkg (with stock pulley 5.5-6lbs of boost,stock manifolds) to be equal to my modified LS2 Pkg. If you do what I've done (change pulley to 3.0
7 lbs of boost with headers) I would expect it to be quite a bit stronger then mine.
You will be very happy with the Magnuson.

Thanks Bushong.. thats the type of info i'm looking for ..
i'm really looking forward to this jump over to a Vette.. i'm currently in a Buick GN thats WHY (700RWHP V6) out there for street use.. it's not even fun anymore to drive. i hope to have a guy in Chicago purchasing her later this month..
i'll folllow up on the header thing with dealer.. most of them would over look that, if the warrenty problem is not due that part... if not, i think i would be happy with a high 10 sec ride.. i will be looking into how to beef up the rear end, is it the half shafts that break? or the rear gears...
The output shafts or the actual housing is the weak link. I think your biggest problem will be with Callaway, I've heard they don't like to change their pkgs. The Buick GN was one car I always wanted and never owned.

Hi Mike,
In case you didn't see it in your other thread yet, the reason you're not getting any feedback from people with Magna Charged LS3's is that the systems aren't available yet.
We're waiting for production intake manifolds and some small components. So we won't have LS3 systems ready for delivery until early to mid-February. The performance data that we've published was generated with fabricated prototype parts. Production parts will perform at least as well.
The problem with long tube headers is that they relocate the catalyic converters and, if Callaway does that (as a low volume vehicle manufacturer), the federal EPA considers us to be "Tampering". That can result in recalls and stiff fines for us. If you install long tube headers, for off-road use, you'll need to change the drive pulley to a smaller diameter to maintain desired manifold pressure and you'll have to modify the PCM calibration tables. Changing the Callaway factory calibration and/or changing the drive pulley diameter will make the car non-emissions-compliant and void the Callaway warranty.
I can understand that, theoretically, there's no such thing as too much horespower, but 580 streetable, emissions legal hp, with a real powertrain warranty ain't nothin' to sneeze at.

i guess i'll lay low with engine / powertrain upgrades for a couple of years.. i just like that it will not effect the 5 year warrenty

thanks for the reply.. the wife will be happy, knowning that the car will be staying stock for that 5 years for the warrenty window
How much is the Callaway package your talking about.. ?
For the 2008 model year, the Callaway Corvette package is priced at $18,500. There are also optional brakes, suspension, interior and other equipment offered.
Here are some links to sections of the Callaway Cars website:

Just a note to comment on changes to the Callaway Corvette warranty for '08:
For 2008 models, Callaway has extended its warranty coverage to additional powertrain components. In previous years, the Callaway warranty was limited to Callaway components and any engine parts that were directly damaged by a failure of Callaway components. Now, most transmission and differential parts are covered under the Callaway warranty. Plus, for 2008, the Callaway warranty is transferable to subsequent owners; it was not for 2005-2007 models.
While the warranty claim rate for Callaway Corvettes has been remarkably low, for 2008, on the advice of warranty service providers, the Callaway warranty term is 3 years or 36,000 miles, whichever comes first, as it was for 2005 and 2006 Callaway Corvettes. Only the 2007 Callaway Corvette had 5 year/100,000 mile warranty coverage from Callaway, and the coverage was limited to engine parts as indicated above.
So your not offering the 5/100 on 2008's you do packages too?? why would you only have that coverage on the 2007 models?
thanks,
mike
When GM changed their powertrain warranty from 3 years/36,000 miles to 5 years/100,000 miles in 2007, Callaway decided to match that term for its warranty. The 2007 Callaway 5 year/100,000 mile warranty covers the Callaway-installed parts and any GM engine part that is damaged due to a failure of the Callaway parts. However, it doesn't cover the powertrain parts that GM would normally cover. Depending on the dealership, if you brought a 2007 Callaway Corvette in with a broken transmission or differential, the dealer might cover it or he might not. (This isn't a problem if you're at any of the Chevy dealers that are also Callaway Corvette dealers.)
For 2008, the Callaway warranty covers the Callaway-installed parts and any GM engine parts that are damaged due to a failure of the Callaway parts, like the 2005 to 2007 models. Plus, the new Callaway warranty has been expanded to include the car's transmission and differential parts. So you don't have to worry about whether the Chevy dealer will honor the GM warranty. The 3 year/36,000 mile term is similar to other ultra-high-performance specialty cars' warranties. A longer warranty term would have required a significant increase in the price of the Callaway Corvette package.

GREAT information to know ... thats great that you even stand behind parts (ie trans and rearends) that you never touch.. i'm still very interested in your package, even if there is a 2 year gap on warrenty..
i'm looking forward to seeing your 08 cars, once that LS3 problem is taken care of.

Still waiting for production LS3 supercharger intake manifolds from the foundry . . .
We expect to have MP122 supercharger kits available this summer for C6/Z06 applications.
We had to suspend LS7 work temporarily to conduct development on the LS3 systems. Now that that is finished, we're resuming work on the LS7. It's still going to take us several months to get everything done, though.
I bought my 06 manual 6 from a gm dealer with 8000 miles on it. being a gm certfied preowned car the powertrain warranty is extended to 100k miles, would callaway match it if i purchased a kit?

Sorry, the Callaway warranty period is not related to any GM extended warranties.
If you were to have us convert your 2006 Corvette into a Callaway Corvette, the Callaway 3 year/36,000 mile warranty would apply, that is, our 3 year/36,000 mile warranty that covers the Callaway parts and any GM engine components damaged by a failure of the Callaway parts. The term of this warranty would start on the date and odometer mileage recorded when you pick the car up from us. You'd receive a package of authenticity certification that would include these details.
