GMPP Prices?

That is a great comment. If that is the case, some of these mods are suddenly very lucrative.

I kind of want to take the car out and see what it feels and sounds like before I add the air intake, headers, and catback system just to see what kind of performance improvement I got for my money.... But if I can save a few hundered I'll do what I got to do.

Shorty headers are a waste of money. If you're getting headers get longtube. Also, just wait a few months and buy aftermarket. 1/2 the price and sometimes better quality/performance.

If it is the case, you probably could convince your dealership to let you keep it for a week or so before they put on the accessories, if you're in good with them...

From what I've seen of the prices of these add-ons its all a waste of money compared to simply leaving everything as it is and only bolting on a blower. Sure...putting more money into intake/exhaust will make the blower even more effective. But just adding the blower alone will give you much more instant performance for your buck than putting $2500 worth of intake and exhaust work to pick up a mere 35 hp or so IMHO.

Putting a blower on and leaving everything else stock may not be particularly good for the vehicle. And I doubt $2500 will buy you a full blower kit...

6k will buy you a full blower kit with about 6psi of boost (going off of g8 magnacharger kit). This kit will come with an intercooler and tune and you wont have KR issues unless you up the boost. You can up the boost when/if you do forged internals, headers etc.

For $200, maggie will "help" you fight battles with your dealer concerning warranty issues, and they obviously aren't going to sell you something that will brake your 35k dollar camaro, and the maggie has a lifetime warranty iirc.

Just some thoughts that I've been pondering if/when I buy a camaro or g8.

It may be worth it to keep in mind some people have to deal with emissions regulations. I've mentioned in my area, if you get pulled over and have parts on your car that don't have CARB numbers, you get a fine that starts at $200 and goes up to $250. Shorties are the only way to go in these instances and since it sounded like there are going to be CARB numbers for these parts, people like me have no choice. I have long tubes on my '02 right now, and it's no fun to drive because I constantly have to look over my shoulder for law enforcement. If I give them a reason to pull me over, they can open the hood and poke around, and there goes another $200 bucks (for the third time).

I can tell you from experience that half the price usually means half the quality. These will have full backing by GM and not bring up any warranty issues, so it's probably beneficial to some if you don't state these options from GM are just not worth it. You're right about the power (and the sound ) but what good is it if you can't drive it without getting a ticket. And don't think our crappy smog laws aren't going to be effecting your states in the years to come. JMO.

Although I think my opinion from above applies to this post too (to an extent) I think you're right about just bolting a blower on. In no time, there are going to be CARB-legal blowers out there and I'm sure a combination of the CAI and shorties are going to amount to at least $1500, and that's a good chunk of $$$ to put toward a blower kit. It'll likely already have a form of CAI and it'll add way more power than the shorties will. I'd still do a catback because that won't be a CARB-issue but this is a very good point to consider, IMVHO. If I could do GMPP blower, shorties, and off-road catback, I think I'd be as close to happy as I could be given we don't know what the Z28 will bring to the table.

That's been an argument that I've been pondering myself. There's a reason for the LS9/LSA to have forged cranks (rods and pistons in the LS9), piston oil squirters, lower compression, different cams, beefier flywheels (9-bolt in the LS9), and different cast heads. I think GM's R&D protocol is probably overkill compared to the testing aftermarket companies do on their prototype cars. Shoot, I want my supercharger car to last more than 100,000 miles, and that's why I'd trust GM's engineers and the reasons they made those engines the way they did. Still, if there is no choice, doing it myself is my only option...

I don't know where one would find a $2500 supercharger kit though... I think kdbolt' meant it was just better off putting that $$$ toward a complete kit

I've been considering this too. They've made good numbers with that G8 and the last I've read, that 460 RWHP was a starting point and at the early part of tuning. Their site doesn't mention much more development but those are still great numbers considering it's an L76 and only had a catback as performance enhancements. I think we could see another 30-40 horse on an LS3 - that would be SWEET!!!

I'm sure it's posted in a few places but what does SC do to MPG?

How much added HP will the drivetrain handle ? anybody know

I'd rather spend the same or less (assuming you install yourself) on a heads/cam package and bolt-ons and get more power and much better mileage and sound (IMO)

a blower is much easier though.

if done correctly, it can improve you mpg. As long as you keep your foot out of it.

That's the million dollar question. The closest thing we have to compare is the G8 kits.... My guess is anything above 600 rwhp is flirting with bad news.

Naturally aspirated motors are certainly a more reliable way to go. And I'd have to say the LS3 with its high Compression Ratio is set up to take advantage of exactly what you describe.

But, Superchargers can also improve MPG and, IMVHO, nothing sounds better than a supercharger. Either way with the stock internals on the LS3 we are hp and/or Boost limited.

Everyone has good points

and that's the beauty of cars. You can do it your way, and if you like it, who cares?

Anyhow,

as stated your mpg will slightly increase if you can keep your foot of the gas, the maggies are carb legal.

and yes you are correct about lt headers being illegal in CA. Sorry to hear about your fines.

It's a matter of preference, but something about hearing that blower whine, really does it for me.

I would agree that 600rwhp is probably the limit. But this will be my dd, and I think anyone would be content with that
