I would recommend going with a different gearing, this will make your car feel like it has a lot more stomp. It will tend to shorten up the top end, so I guess it really depends one what you are looking to accomplish. Feel free to call me if you want to discuss your options.

Good Luck!

 

The best overall gain for you car is 100 cell cats, it truly is one of the best mods that will wake up the NA. Other then a charger and maybe the plenum nothing else works...Ask me how I know

 

i have a 996 3.4ltr in my early girl boxster with a 6spd and all s running gear I live in australia and we have dynos that appear hungry in comparison to those state side however here goes .
996 3.4ltr 221KW my99 made 166kw at wheels 3 examples present all within 4 kw
996 3.6ltr 235KW my03 made 174kw at wheels 2examples present
986 3.4ltr 221KW made 196kw at wheels
modifications include
starr performance headers
100 cell cats
starr muffler
BMC CDA air intake with 70mm feeder pipe and cold air intake
shrick cams
remap
AANSCO Lightened flywheel
custom clutch plate ( with centre springs)
quaife lsd (a must to eliminate axle shake and for power down)

still to be done
rss intake plenium , need a good deal if anyone can help
HR coilovers still in the box after 4months
GT3 brake upgrade still in boxes 15months
oh well patience is a virtue

Schrick makes cams for the 3.4 porsche engines? Where can I find more information about this?

Also, does anyone know if there are any lightweight pulley upgrades for our 996s? I had it for my M3 and it sure did help the engine rev much quicker.

 

suspension & wheels

 

My car has a cold air intake, fabspeed exhaust and a chip. My buddy just bought a 996 (same year as mine, 2000) and his is completely stock. Mine FEELS much faster. Part of it is the sound but it seems much more responsive as well. After driving mine and his back to back, he has started down the mod trail...

Personally, I don't really care what the dyno says (don't get me wrong, I feel more power is better than less power) but my car is a Daily Driver so I want it to feel fast.

Please let us know your results...good luck.

 

KN Intake kit and Agency exhaust gave me 15 more whp, dyno tested. Not much, but my main reason for those upgrades was the sound.
The mods which gave me the greatest driving improvement are: Kenwood DVD NAV, KW Variant III coilovers (frigging awesome), and the GT3 RS bumper + MKII side skirts.

 

more info on the cams please.

nine9six: the GT3 RS has a different pulley (read: lighter?) on it. Swapping to that one might be worth it, but i don't think the pulleys on a 996 are a significant source of power loss. On some cars (m3's and rx-8's and stuff) they help the engine rev a little more, but on a 996 i'm not sure if they would make a difference.

if someone made one though, i'd buy it to try it out. a lightweight flywheel and pulley on an rx-8 makes the car rev like nothing else i've ever driven, its great fun.

There is the Cam link

 

The only thing that really makes sense is weight loss, supercharger, and suspension. The bolt on aftermarket mods, chips, CAI's, exhausts, etc are really good at losing weight from your wallet but have a pathetic return on investment, especially in the over-priced Porsche parts market (yeah, I know that the market is much smaller and they need more to cover costs of development .. yada yada yada). CAI and exhaust sound great but get almost nothing performance-wise.

320 whp is probably possible but not with something you want to drive every day on the street, or pay to have built.

Another idea that hits two points is a lightweight flywheel. Reduces the driveline loss and the curb weight.

 

These guys have a underdrive pulley for the 996, 986, 986 and 997.

Which 100-cell cats are you running, and did you have any issue with CEL light?
I've seen Fabspeed's 200 Cell cats, what's better on an NA car 200 or 100?

 

Coilovers!! =)

 

Exhaust would be great too because my C4s is just tooooo quite for me!!
