my 2008 has had a Edelbrock Eforce for about 6-7 years (can't remember for sure) but it has been trouble free. The car is not a daily driver but I love the low end torque for better drivability. I don't plan on selling the car anytime soon and like my setup.

 

Keep in mind that with the ECS and A&A kit there will be some trimming to the bumper cover underneath, trimming of radiator and a cpl other pieces. Its much more than a Procharger, Heartbeat, or Edlebrock needs. I mention this only because I wouldn't do it to my GS CE...but I have a base...sooo

 

I would be concerned about poor reliability for a daily driver and lots of expenses and headaches.

 

That I didn't know.

 

Why does everybody miss out on the point on how to do a supercharger install properly? Things like gapping the rings and forged internal engine parts are the way to do it right. Of course that increases the cost but if you are into serious power and want reliability the engine as well as the rest of the drivetrain need to be upgraded as well. Then you may fall into more money than brains category, but it sure is fun if you have money to burn.

 

Sure, that's a better way for big HP...but not everybody is looking for 'Texas' power

 

I had an MP112 Magnacharger on my Avalanche for 12 years and put 70k miles on it before I got rid of it a little over a year ago. It had 285 hp stock. After adding a blower cam, headers, a 2600 stall, and pulleying down I made 475. It was a blast to drive and I never touched the supercharger after install - no additional maintenance of any kind was required. I drove it hard when I wanted, which was on a regular basis.

Personally, I think a roots/screw supercharger is at its best on a heavy vehicle as the immediate, off-idle, massive torque available can be put to good use to get that weight moving. A Corvette is traction challenged in stock form off the line, so a centrifugal blower makes more sense to me. You can address the roots/screw traction issues somewhat with tires but ultimately you will have to get good at regulating the traction with your right foot.

To your question - if I was going to install a roots/screw type blower, there is nothing wrong with the Edelbrock unit. I would also take a hard look at the Callaway unit and the Heartbeat unit.

One last thought; if you are going to put a ton of miles on a supercharger, I believe the roots/screw units have more long-term reliability without additional maintenance/rebuild requirements. I may be wrong about this, but it is what I have personally observed over the past 15 or so years.

 

15K is my limit for whatever i decide to do as far as boosting HP. Or 30K if i decide to trade it in on a new GS.

 

I had the e-force 599 kit installed by an Edelbrock authorized installer (a new car dealer who also has a race team). The LS3 dry sump kit was ~$9k and the install was another $1500. The car was running at 500 rwhp.

I had a cam/springs/HB install this past May and the car is running at 605/614 rwhp/tq.

I'm a cruiser and waxer most of the time so I don't think I will be breaking internals at this number.

If you are looking at max power go with a centri of your choice. If you are looking for a <200 hp bump and a bulletproof system, go with an e-force but that will cost ~$2500 more.

 

If 15K is your spending limit, then it just comes down to which supercharger you prefer. Its annoying seeing people post 6-8k for a supercharger. Like CadVette pointed out, it takes a bit more money when done right. And a grade A shop will cost even more come time for the install (don't wanna have just anyone install and tune it). Personally I'd wait it out a couple more years and get a C7 GS. Now if they at least bumped the new GS to 510-530 HP, I'd say it would be a no brainer to move on to something better.
