Toying with the notion of supercharging my 2011 GS M6 with 10,500 miles. Street car, not looking for 700-1000 hp, but I want a good unit with some street cred. I just bought LG Super Pro 1 7/8" lths too.
Im going to be voiding my factory warranty, and want something that wont destroy the normal running of the motor. Looking at ECS, A&A, and 2 LINGENFELTER packages. Looking for 600-630 hp or so. Just something a little more if you know what I mean. Lingenfelter has the name and rep behind them for corvettes. Plus the warranty. I can get ECS and A&A for half the cost, but is it worth it if I try and resell the car. I would think Lingenfelter would look better to a corvette buyer? Header tunes void even some of the supercharger warranties though dont they?
Should I scrap the idea before I get in too deep?

 

All the choices you laid out are good.
I am a believer in name recognition and letting Lingenfelter do the work will hurt the value less. Just remember you'll never get the dollars back out of it but the fun is what you are paying for.
If you want sexy put a Maggie blower on, or the Edelbrock unit fits under the stock hood.
The A&A, PAxton etc - front mount blowers - all work well but to me they seldom have the same eye appeal as a manifold mounted blower

 

I already had the hood done for the intent of a top mount. I just need some other opinions on all of it.

 

Do headers make a car hard to sell? Or are many people happy to get a car thats been tuned with headers?

 

My opinion is yes. You automatically eliminate states that have visual inspection laws. For instance I'm not aware of any full length headers that pass visual in CA. I used to live in Seattle and the WA smog laws typically followed a few years behind CA, so that may be another buying population you'd lose. I seem to recall there are 6-10 states that take the lead from CA and lag 3-5 years behind regarding implementation.

If Smog is not an issue, you also have to appeal to someone that wants the increased sound. Most of those buyers will be younger and will purchase via a loan. The older the car, the more difficult it is to get a loan, which means you'll be selling to those 50 something cash buyers. If you're going to sell next year, probably no big deal. 5-7 years down the road it may be an issue.

Regardless of the above, you can always install the headers and then remove them prior to sale. You'll recoup a bit of the expense by selling the aftermarket parts stand-alone.

 

Whoa.. that hood is pretty cool.

I've been going back and forth (of course it's much easier to just "think about it" when you don't have the $$ ready. ) about doing a something like the edebrock unit on my DD 07 as well.

I like the idea of it all fitting under the stock hood, so it "looks" just like the average C6. Until one starts it up.

I'm concerned (but less so the more I read) about reliability of a supercharger added to my DD, as I put about 20K on a year. But we will see.

Of your choices - which one gets you closest to your stated goals?

 

Feel free to PM me if you would like "a deal you can't refuse".

We sell 100's of these kits per year and the resale is not bad on ECS kits at all. Much better then some of the other kits if you follow the boards.
LPE is a fantastic company with great people there, but I do feel we give a much better bang for the buck.

 

Thanks Doug, my buddy Josh at Accelerated Performance in Toledo got me quotes for ECS and AA. Both at half of the LPE Packages. Just still weighing lots of options here.

 

I got my A&A kit for the same reasons you want yours, haven't looked back. More than enough power for me, no effects on driveability or reliability so far. Been caught on 1hr plus bumper to bumper traffic this summer, not a hiccup.
I feel that the same can be said about the other kits. It's only when pushed to their limits that these kits, and anything else for that matter, start to fail. If you're not going for the moon, you won't regret the additional power.

 

I debated forever on going the supercharger route, but ECS truly came through with an offer I could not refuse (and a good reputation from everyone I talked to). My Corvette is at ECS right now getting supercharged. I can't wait to get her back!!! Thus far, ECS has been a pleasure to deal with (been dealing with Scott). I will fill the forum in once I get my Vette back.

Thanks again ECS for a great deal. Can't wait to get my baby back.

 

Nice ride Ron...

 

FYI what I worry about as far as what happens to the car is running temps with SC and Headers. We get pretty warm here in the summer, so far it hasn't been an issue with a stock LS3 but what will happen if these things are installed ??? Definitely do not want reliability to suffer.
As I read all of these posts about this subject plus the advertiser offers it looks to come out close to $12-13K for headers and SC plus install, is that about right?? And is 91 octane still OK for fuel??

on my 2009 C6 I went back and forth on grabbing a supercharger but just never went thru with it, maybe in the back of my mind I thought I was always going to get a C7? But looking back I think if I would have done the forced induction on that car I would of probably kept it and not got a 7. So in truth the supercharger system you choose might cost a little but might "save" you money down the line

With all that said it sounds like you are looking for the power but are also looking for a system that's pretty easy to install, rock solid reliability, and will last a long time. For me the decision on which unit was a long process. The centrifugal systems are killer and you can really tinker with them and boost away more and more if you like.
I ended up grabbing a C7 and knew that the edelbrock eforce would be what I was after, plenty of boost and pretty easy install. Also it just looks amazing when you pop the hood. Their reputation and reliability have got to be one of the best in the business.....

Side note: (but probably an important factor on your decision making) On the C7 with direct fuel injection you don't have to worry about adding a new fuel pump or "boost a pump" since they already have around 100psi (unless you plan on running more then 8 lbs. of boost or so). On the C6 you will need to probably run some system to increase your fuel pressure (not sure if you need to add fuel pressure on the eforce system tho?) So that's one thing I would investigate first to help with your decision. Good luck, paul

 

There are a couple ways to think about this. There are people that will not go near a supercharged car at all. Beat on-undependable.etc. Of course there are those who want power but don't want to go thru the work and would love the car already built.
I came out of a supercharged car and back into one with my C6. It was an ECS kit which I already knew about and was pleased. This car has been for the most part very reliable ( only 22K in 2 years). Which ever way you go-enjoy

 

12-13 sounds a little high just for an SC and headers. We could install our system, American Racing headers and meth injection netting you near 700 rwhp for less then that.

91 octane can be tuned for, but it would hold the power back a bit.

 

I thought about going S/C. Till I saw the price tag. Couple a years ago it would have been about 7-K for the whole package, and thats one that didn't need a new fuel pump. Regardless, good luck...and don't forget about having that HB pinned.

 

If it wasnt for pinning, I would install it myself lol..I dont have the means to get all that stuff out myself lol..Pisses me off GM doesnt make it that way from the factory.

 

Do it, you won't regret it no matter which blower you pick. Personally, I prefer the centri (A&A or ECS) because it's less noticeable under the hood (although that's not as true now that I have dual nozzle meth), has more HP potential, and doesn't add a bunch of low end torque. Our cars really don't need any more torque, even stock they can roast the tires, and there's a reason GM put PTM on the ZR1s.

For anyone concerned with heat, do the Dewitts radiator (comes with the A&A kit for GS/Z06 and can be added to the base A&A kit or ECS kit). Also, you might as well do meth from the start as you'll be adding it eventually (especially if you don't have 93 octane available).

FYI, the car made 407RWHP with just Z06 exhaust manifolds before the blower, and 600RWHP after the blower. Then 672RWHP with 3.6 pulley (11psi) and meth.

Looks nice..Satin black is the way I would go too.
