Unless you supercharge it or put the car on a diet you will be hard pressed to notice any significant changes by doing the usual mods of intake/exhaust/chip.

Track lap times on 20+ more HP would would be very tough to see any change IMO - now money spent keeping the tires on the ground and your butt in the seat....
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I am very blessed to have a 40th Anniversary 911 with only 30K miles. The power is good but I am curious to learn if there are any tuning mods that could be made to improve the HP and Torque? Certainly a SC or Turbo is out of the question.

I just got 20hp from 5-7K RPM over stock with my custom header/exhaust/cat setup. Below 5K about the same. Shaved 65lbs off the rear, too.
It's possible.
The Anniversary model is probably the third best naturally aspirated 996 model in terms of HP and torque. You won't be able to get much more out of it. And trying to get 10-20 more HP is very expensive, with mixed results.
As Whitey said, take it to the track and you'll see.
IMO, the mod money is probably best spent elsewhere.

+1 for spend some time at the track and if the claims of 20hp can be made from simple exhaust swap, dont you think Porsche would have done it already?
Less weight I believe, better sound... ok...
Even if I had another 20 HP I doubt I would be able to really feel the differance other than in my head. Track lap times on 20+ more HP would would be very tough to see any change IMO - now money spent keeping the tires on the ground and your butt in the seat.... that will show up !
back to my original Q : why do you think you need more HP/Torque
I agree. The package is well optimized from the factory.
I tuned one to 340RWHP but I had to pop it open and make it bigger to do it along with more head work, etc, etc. :-)
Its hard to beat right out of the box. Most of what you will do will result in LESS net output.
I drove a 40th back to back to a 2005 997. The 40th's motor was much better in my opinion. I liked how it revved and how the motor sounded. Much quicker revving as it felt like the flywheel may be lighter. Or it could be the motor internals as well. It just sold at the dealer I bought my 2002 996 for $46,000. That 40th had around 15-20k miles and nearly flawless.
according to
www.etusivu.info/porsche
the net weight is 1370 (kg) or about 3,014 lbs.....so curb weight with all the fluids would be about 3,100? or the same as a Carrera 2?
They aren't right, at least for US models.
My 02 996 C2 with no options, no PASM, 6 speed, stock, no spare and no tools, weighed 3450lbs with 3/4 tank of gas. I don't know where they get those numbers! So, I removed the radio, seats, center console, and it still weighed 3300lbs. I then removed the sunroof motor, mufflers, and installed a lightweight battery (10lbs versus 45), and the car still weighs 3050 with NO GAS. So, a heavily optioned 40th with spare, tools, stock seats, certainly weighs close to 3500. I'm sure someone here has actually weighed one! Until then, it's speculative! It's also frustrating because the club race rules base their class weights on some number that's impossible to get to... 2960 lbs with driver!! But that's a separate topic!
Garrett the minimum weight for your car in 996 Spec is 3040 and you should be able to get there. You still have the heater core, lower dash, dash brace, interior paneling, carpet, sound proofing, and the sun roof panel. There's lots of hidden weight in that car so get to work and join us in 996 Spec....
