2006 Cayenne Turbo vs 2006 Turbo S

2006 Turbo S has 520hp. Can't say for sure on the other questions but IIRC, they're basically the same car so I would suspect the cat bypasses and reliability would be very similar.

 

IMO you'll notice a bigger difference upgrading to a new non-S turbo simply because of the significant weight loss. I think it was somewhere around 500 lbs.

 

There are two ways I would go with this.

First would be that if the color of the new one is that much better than what you've got, go ahead and upgrade.

Option number two would be to take some spare cash and upgrade the current turbo so that it has similar HP numbers as the S. Then I'd upgrade to a 2011 Cayenne turbo in 2-3 years.

 

you can install a chip on the engine which will essentially turn your turbo into a trubo-s. the dealer can do this for you! i think it costs around $2K.

 

+1- save your money. The new cayenne is a big upgrade- that weight loss is significant, and the car magazine reviewers loved the new turbo. To me, spending a lot of money to get HP from 450 to 500 is pointless in a car like this. We had a titanium edition which was great and a turbo would be better, but not for any serious kind of money- these are daily driver people haulers, not sports cars- a fraction more of horsepower isn't going to get me excited We only sold our cayenne because we needed 3 rows by the way- was a good car/truck but I'd only buy one with low miles used or a great great price new as these are just SUVs- very nice yes, but just SUVs.

 

The engine horsepower increase is not the only difference in the 2006 Turbo and the 2006 Turbo S. The rear track is wider and the brakes are larger, much larger. The ride is slightly firmer as well. It is not, however, "rougher," but more solid feeling.

 

Well, even if you wind up doing no upgrades, a non-S cayenne turbo/430 combo is an excellent one!

I almost kept our cayenne for myself when my wife got a 3-row enclave, but sold it as I put the money towards a 360.

 

I just added a GIAC chip tune to a 2008 DFI Cayenne Turbo a week or so ago. The gent that owns it proclaimed "you made this into a new car!"

It was approx 500HP stock & I took it up towards 600 - but the big news is the torque. The chip flash shows 250+ Lb Ft added. I spent a lot of time with this machine & I can tell it it was a hoot. We pumped race fuel in it and with the race program it was mind-bending quick.

Now THAT is what you should do to any Cayenne Turbo. $2000 for non- DFI Cayenne's and $3000 for DFI units.

 

I have been chip tuning for years. I am happy to give you an honest appraisal and thoughts.

I have some customers who are still driving twin turbo Porsche's that I added GIAC boost, fuel pressure, throttle mapping and advance curve to over 5 years ago that have had no adverse effects (at double the stock boost levels and constant power-on runs). That has some to do with the GIAC programming (intelligently done) but lots to do with the quality of the base engines we are working with.

As for engine life, I tell most all of my upgrade customers to expect up to 50% longevity reduction. Meaning that if the base engine would perform perfectly for 200k miles to expect 100k miles of modded non-issue enjoyment. Seems easy enough to accept and has not been an issue anyhow.

All of the GIAC programs are canned maps & curves set well within the safety parameters needed for drive-ability & reliability. Yes you can ask for "X" programs or "Race Only" 117 octane plots but in general they are not needed. These are good base programs that will impress and not disappoint. With a turbo car you gain low and high end. No loss at any rpm. Even the naturally aspirated programs represent fair gains throughout the rpm with no loss.

Downside? After years of this I have never had a recipient of mine complain or point out a downside. No CEL, No hard starts, No worn or blown engines. One BMW 335 with 60k miles had a upset wastegate from corrosion but that issue was not because of the programming. I now have the staff clean all 335 & 535 wastegate actuators so the possibility of that will be minimized.

Lastly, not being local to you I don't have any dog in this hunt, this is just an honest rundown. Check the GIAC website for a local vendor and they will take you from here. You will be happy I would bet.

 

these 2 vehicles are in my "stall" as we speak! both in black, i might add!

 

I dont think so. Porsche's stock twin turbo tuning is very conservative on all versions. Like I said, we are getting over 250 more Ft lbs of torque with the tune on the late models. They leave a ton on the table with the factory tune.

 

I do not have any experience with the Turbo S but I have owned several Cayennes, 2.5 years ago going from a 2006 Turbo with 450 hp to a 2008 Turbo with 500. There is not a lot of difference. I would definetly wait to upgrade to the newer, lighter model.

 

Oh sure. If you opt for the "switcher" you can have the stock tune, a 91-93 octane pump gas tune (safe), a race tune (safe with 100 octane), a valet tune (safe from dummies), and a anti theft tune (safe from thugs). All in one hand-held device. You choose your poison by a simple touch of the button on the fly. Nice 'eh.

 

The color and rims look awesome! Anyway to get rid of that tow hitch? hurts the rear look of the car a little...

Good luck with her!
