Hello all,
Not new to Porsche but new to Cayenne. Just picked up a 957 Turbo and was wondering who you're going to for aftermarket performance upgrades?


Also wondering what the performance(HP) differences are between Turbo And Turbo S. Meaning, where does the extra HP come from with the S?

I believe S runs a little more boost. Not too many options tunewise on this generation.
I would update fresh plugs/DV's/ secondary cat deletes and tune. I went with softronic.

The extra power is entirely just software to my knowledge.

As far as extra performance goes - I'm not sure if the gains you can reasonably achieve will be noticeable outside of a dyno. It's a heavy vehicle and everything is designed well so there isn't much potential left on the table.

The HP difference between the 957 Turbo and Turbo S is software/tuning related, higher PSI on the boost, and it has larger intercoolers to handle the increase in boost. The performance mods for a 957 are as mentioned above. Best bet is cat deletes, an ECU tune, and maybe a cold air intake. A fellow member named Lupo.sk did a very impressive rebuild with a ton of performance mods on his Cayenne and it was amazing but a lot of work at the same time. When you start messing with the turbos things get complicated was my takeaway from his posts. I would stick with the basics. Best of luck and welcome to the party!

Hello. When doing a cat bypass like the fabspeed, does the cayenne need to be re-programmed (tuned) with the likes of softronic or eurocharge? Or is it just as simple as removing and replacing and you're done. Thinking of doing the cat bypass on my 08 GTS. Thank you.

+1 for Secondary Catbypass.

Direct bolt-on replacement with no CEL, picks up +27whp/22ft-lbs along with a deeper, throatier exhaust tone.

A tune is not required but always recommended, especially on the Turbo applications. ECU Tune on the 957 Turbo picks up +71whp/80ft-lbs along with driveability improvements (better throttle response, smoother/more linear powerband).

Running 10% off this month if you're interested. PM me for more info

Whoa, that does sound wicked.

Have you done side by side, dyno runs to confirm the whp increase?

BlackTurboS

Yes Fabspeed dynod their stuff to confirm the stats before posting it. You can find the video on Youtube of one of the first Cayenne Turbos they chipped and put a bypass on. The dyno report is also available on their website, or at least it used to be. When fabspeed says you are getting X HP; they have confirmed it on Dyno. They don't mess around.

How far do you want to go? The right answer is in thousands of dollars

It's an internal combustion engine. More fuel + more air = more power. Drivetrainwill last, no worries.
You can do bigger injectors, bigger ICs, new larger plenum, larger IC piping, hybrid turbos, boost controller, catless system etc. and you'll get some pretty impressive numbers. This road is not for anyone so only go down it if you don't mind pulling the enine and throw thousands and thousands of dollars into the fire... I mean pig.

I still haven't finished mine and it's been quite some time now (3-4 years, dunno). My biggest problem is time to get everything together the way I like and explain to my indy what I want.

If you just want "some" more bang for your buck, go with the secondary bypass pipes, get a tune, maybe get larger ICs and always gas up with 93. And have fun.

Where are you purchasing these parts? Intercoolers and such?
I'm gonna do a full 3" exhaust and eliminate all the cats but indefinitely wanna do larger intercoolers and piping too.

Do it all at once and save a lot of money (I mean exhaust, ICs and piping). BTDT. My 06 is a CTTS so it already had larger ICs. You can buy them used or from FVD or OEM. Google is your friend.

Catless system will make a lot of noise, be prepared. And spit flames out of the exhaust if you tune it right ;-) I actually put in a set of "secondary" 100 cell race cats but kept catless downpipe.
