My opinion would be to call Callaway. I think their 627 HP package is $17K, and you get a warranty. That is how I would go if I was interested in a Supercharger.

 

Callaway is certainly a good way to go. You'll get a well developed package with a 3 yr/36000 mile warranty on the complete drivetrain that covers all the stuff your GM warranty doesn't. I had a 2006 C6 A6 with a Lingenfelter maggie PD supercharger that ran flawlessly for 7 yrs and 48000 miles, before I replaced it with a new Caddy CTS-V. There wasn't any supercharger whine below around 2000 rpm, no gas fumes, cats didn't need replacing, or any of the other concerns mentioned on here by others. Basically ran just like stock, until you started to put your foot in it, and then the full torque of the PD blower instantly transformed it into a street rocketship. Since you don't want to spring for a Z06, I would go in this direction. There are other well regarded forum tuners who have supercharger packages without a full warranty at a lower price point. Case in point, 21st Century Musclecars in the Dallas area has a price of $10,000 installed for C7 Edelbrock PD blower. If you use the Edelbrock supplied tune, there is a free warranty thru Edelbrock that covers up to $16,500 in damages to the drivetrain for I believe 3/36 from the date the C7 was produced.

 

Keep one thing in mind when you add forced induction as a aftermarket change. You will reduce the service life of the engine substantially. If it's not a daily driver and you are only going to put 5000 miles a year on the car perhaps not a issue.
If you plan to keep the car long term I would read up on what changes went into the Z06 to produce a engine they felt would provide long term reliability and be warrantable. Pretty eye opening!

 

I agree on the view that the car isn’t slow, quite the reverse.

Re nitrous, none other than John Lingenfelter didn’t recommend it saying that it had more potential for serious engine damage than most other power adders. Hard to disregard someone with his background. Don

 

That is simply false, you would have to take his comment in context though. He could simply have meant that it's easy to misuse.


All power adders increase cylinder pressure by increasing volumetric efficiency (actually over 100%) and the amount of available oxygen for the engine to burn with fuel. All power adders that use compressed air have increased IAT (intake air temperatures), so essentially the air being let past the valve into the combustion chamber is hotter than the ambient air being pulled through the air filter (and also hotter than the air would be from simply running through the intake manifold and cylinder head). Increased IAT's will cause detonation sooner than cooler IAT's all else being equal. Detonation is the #1 risk to cause engine damage with a forced induction application.

A fundamental difference with nitrous from compressed air power adders (all supercharger and turbos) is that it actually lowers IAT's, the nitrous is very cold as it exits the bottle. It doesn't lower them a ton but the fact that they are less than ambient and wayy less than a blower/turbo is a huge deal. It also means that nitrous powered cars are not as effected by weather conditions as N/A or turbo/blower cars.

Another difference with nitrous from turbos and blowers is that it's not "always on". I understand that superchargers have a bypass valve and turbos have a wastegate but in reality the power is always available, as soon as you roll into the throttle the car can start making a few psi of boost even with part throttle driving. As stated above that is putting more stress on the engine every time you make even a little bit of boost. Nitrous doesn't do that, you can drive around 99% of the time with no extra stress on the engine and only turn it on when you are ready to get busy.

Nitrous kits are also WAYYY cheaper than supercharger kits. The best of the best nitrous kits are about $2k with every needed option/accessory. The lower end kits are under 1000 bucks, they are also way less labor intensive to install and require no permanent modifications to the car. My Kenne Bell kit took me over 30 hours to install on my 2012 Mustang (being a perfectionist) and I had to cut a huge hole for the air intake in my car, among other permanent modifications to vacuum and PCV hoses. Nitrous kits also add a lot less weight to the car, and don't add all of it over the nose. A typical supercharger kit with intercooler etc is about 100 lbs right on the nose of the car. A nitrous bottle is 25lbs full and goes in the trunk (and is also easily removed if you don't need it), the rest of the kit is maybe a few lbs on the front end.


The two main downsides to nitrous are the fact that you have to keep filling the bottle, and it's easy to get carried away with (which may have been the reason for Lingenfelter's comment). On a 125 shot I could get 6 full 1/4 mile passes at the drag strip out of one bottle (still had some left just the pressure would drop and it wouldn't be as effective). If I had installed a NANO kit I could have gotten even more. My local shop charged $40 to fill the bottle, but if I had invested in about $200 worth of equipment and bought it 90 lbs at a time (and used a mother bottle to fill my 10lb bottle) I could have gotten it for half the price. Even horsing around on the street there's no way I would use more than 2 bottles a month, so you can see that at $80/month it would take a long long time to even match the price of a supercharger kit with installation. It's easy to change the jets and go for more and more which for people without good self control can be a bad thing.

I didn't mean to derail this thread to be about nitrous, I was just addressing your comment and maybe enlightening some people that are scared of it for no reason.

 

Time I'm done there it would approach 19-20k and all I'd have is badging and a SC. I'd rather spend 30K and get all the goodies a Z has to offer. Plus I can get an EZ 6k off a Z locally. Thanks for your input.

 

As I guessed from your original post, sounds like since you've already taken the original hit on depreciation, you just want a relatively cheap supercharger install, rather than spring for the big hit on a new Z06. If it were me in this case with your possible goals, I'd just go ECS, which isn't far from you, and have them install their ECS 1500 kit or an Edelbrock PD, depending on whether you want to go centrifical or PD. Both good choices that will take your vette fun up a huge level.

My Z06 is doing as GOOD or better MPG than my blown Z51. The over all car is worth the upgrade over the z51. The gearing suits the car better in the Z06 vs the Z51.
The oil issue that can be there for the Z51 was disheartening at best.
Don't want or a catch can or fumes.
Cenrti's can be great though.

 

Sounds right to me.

 

Thank you for adding your information to this thread. It is a consideration. Lead time?

 

Glad it was helpful Our conversions take about 2 weeks with scheduling. We're booked into May right now, but would work to move stuff around if possible.
Please drop us a note if interested: info@callawaycars.com

Thank you -

 

Thank you. Now my other question would be is my car's value enhanced with the Callaway conversion?

 

As a general rule of thumb, when you put money into mods, you are never going to get that money back out. The car might be worth more than it would be stock, but not as much as the value of the car plus the mods.

 

I agree! Why spend 17k on something it may net you down the road like 5k?

 

If you're doing it for an investment then I would say you should never do it. But I think OP is looking for something he is going to like and enjoy, in which case I always ask one question. Are you going to have more fun with the $17k in your car, or in your bank?

If you plan on selling the car in a year or two I would highly suggest you don't do it because you'll just be flushing money down the toilet. If you plan on keeping the car for a long time and it's something you want to do and can afford, then I say go for it

 

There are risks to anything and some people do not like to add risk, no matter what the reward is. Don't listen to people who think its a sin to change anything on the car. After owning one C5 and now on my second C6 I pulled the plug and had the A&A kit installed. Will you get 100% return on it when you sell it? No. But then again, even people who redesign something on/in their house ever see 100% return. Life is about enjoying what YOU want, not want someone on a forum tells you.
Drivability in NOT affected in the least. Might want to read this thread and how reliable a properly installed supercharger can be:

Thanks to everyone for such helpful responses. They are so helpful.
Seems like there are so many options. So many toys!

 

Our cars seem to hold their value in relation to the overall depreciation of the base vehicle. In other words, what some dealers have said, is if the car deprecated 30% over a period of time, they apply the same 30% to the Callaway content. It seems to work for all, including the banks which write loans on those pre-owned examples. I am sure that other superchargers don't see the same from what I hear. But with anything, there can always be variables on all sides.
