I am currently building the 997.1 C2 I recently picked up/ inherited. I have a fully built 987 S and I'm kinda going down that same path. Are there any documented full builds for proven max power? Honestly I should sell it for a 997.2S but being on an island thats not really practical.
Current mods are
BMC air filter in stock airbox
IPD plenum,
Fabspeed Maxflow mufflers (mufflers only)
Numeric short shifter
Rear seat delete
Recaro Profi SPG XL seats.

I plan on adding
Fabspeed headers
Fabspeed high flow cat x pipe
Aasco lightweight flywheel
RSS underdrive pulley
tune.

I'm not really sure who to use as a tuner. I cant really find any detailed builds like I could for the 987S.

Full power? Don't buy those mods and rebuild the engine.

I'm with cw on the engine power. Those bolt-on mods you listed may help a little bit, but a rebuilt engine with larger displacement is where the real power gain is. You want to talk to Softronic about the tune. It's one of the most respected Porsche tuner.

I saw you have the Aasco lightweight flywheel and RSS underdrive pulley listed on the planned mods. Make sure you get the whole kit with the sprung clutch and the harmonic dampened version of the underdrive pulley. Your engine will thank you for it.

Also shameless self promo of my build. But instead of power, I'm after weight reduction. I have a whole speadsheet of info on that. https://rennlist.com/forums/997-foru...treet-car.html

Honestly I would go for a supercharger or turbo kit, ROI would be much much higher. Kind of a niche but there is a group on Facebook with some pretty good discussions. I still haven't seen much proof of real solid power gains with plenum, pulley, etc etc.

If not your best bang for buck is reducing weight like J.Tan. His thread is really informative.

Great post. Love the weight saving work in your link.
