X51 vs. Dealers's Homebrew
All - I see another thread about the X51 but thought these new data points merited a fresh start.
I just inquired at my dealer about the X51 and this was his - somewhat surprising - reply:
The X51 Power Kit from Porsche increases your Horsepower from 400 HP to 430 HP. Installed it goes for $22,500.00 plus tax.
Here is what is included in the X51 Power Kit:
1. Contains modified cylinder heads and camshafts
2. Newly developed variable resonance intake system
featuring 6 plus 1 switchable valves
3. Center cooler
4. Optimized engine control including a new engine compartment styling with a titanium colored cover and inserts with "Carrera 3.8" or "Targa 3.8"
Our Power Kit that we offer increases your Horsepower from 400 HP to 445 HP. Installed it goes for $11,270.00 plus tax.
Here is what is included in our Power Kit:
1. Performance exhaust system
2. Performance intake system
3. Performance tune
4. Performance high flow filters
Is this some kind of alchemy? 50% more HP boost at 50% less cost? And with bolt on parts? And all warrantied from a dealer?

Cobb + Headers (sport Cats) + IPD Plenum + Intake is the recipe for reliable bolt on power.
Exhaust for sound only.
Edit - Looks like you have a #1 car and not boosted.

If they have dyno sheets to back those number up then I'd do it in a heartbeat. FWIW the AWE exhaust I have claims +20HP/ +25TQ, so for $3k thats a pretty damn good deal if you ask me, although I have yet to put the car on the dyno to verify those numbers.

Do you trust that your one local dealer will (and can) supply you a new engine, should yours blow?
Or will they do all the warranty work on the engine/drivetrain that tends to crop up in the first year or two of ownership?
Plus, I'm pretty skeptical that the homebrew kit will produce that much of an improvement. Even if it does, the Porsche kit, with some pretty significant engine parts seems like it will protect you better. All that extra power equals more heat. The X51 kit factors that in (center cooler) while the homebrew is hoping that just bringing more air in and out will solve that. Heat is the biggest killer of engines, if not managed properly.
Hell, while you're at it, go to the local ricer store and get a coffee can muffler... they're good for another 10HP, at least!

For 10K you can buy a hell of an aftermarket warranty that will cover the car as it stands at the time of initiating coverage. If you want warranty, that will work.

If, of course, you buy the 45 HP boost from intake, exhaust and a tune.
Maybe they used the Stargate Saddam had to figure out how to get to that number....

Keep in mind that the X51 package includes new heads with revised cams and a new intake plenum. Plenum, not just a box. So it's a crap ton of labor. There is a thread on here detailing the install. You understand why it cost so much money. The parts cost is expensive (new heads!) and the labor is also very costly.
The dealer's package really probably only has some form of Cold Air (Hot air most likely) intake, not the actual plenum.
