I have NOT done the upgrades yet but will within 4 weeks. I am waiting for my GT2 build to be completed and in my hands before I pass over my 997.2TTS.

 

Skeeter:

I agree with this (power loss w/Exhaust upgrade) but what if you remove the cats? or ven add hi-flow cats?

Thanks,
Slow

 

From what I've read, headers aren't needed till you start doing big hp upgrades...I had 200cel cats and honestly noticed nothing...I will say they were made very nicely and fit very well...I bought them because I got a great deal on the whole setup...

CAI won't do much for you other than add some bling to your engine bay.

Headers won't add much either. I would save that money and apply it towards a new clutch. You will be needing one soon with those mods.

Am Im looking at the Sachs/AWE St2.5 Clutch? or should I get the Sachs St3 Clutch w/ LW Flywhl?


I hear the Sachs 2.5 is more than sufficient for modeate upgrades like exhaust and tune. I went with a stage 3 just in case I wanted to do more than what I currently have. The LWFW will give you much quicker throttle response and your heel toe downshifts will be much livelier too. The down side is the chatter you will hear at idle.

 

Agree with skeeter. Exhaust and tune is all you'd do on your .2tt. The intercoolers are the same as the .2ttrs which have no issues handling 1.6 bar and the exhaust is an easy decision. You simply can't compare a tubi to a Europipe on any front. The EP also won't drop power without a tune and will give you more down low before the stock ecu kicks in. Contact stef at EP and he will explain plus there are a few members/users that can verify this as a fact. With a tune it can only get better.

 

Depending upon who's tune and exhaust you choose you'll may see @500whp up. On your list i'd shake everything other than the exhaust and tune, but be wise in that selection. Add a Sachs clutch (764 pp) to the list as you will most definitely need that. Plugs may also be needed depending on how many miles they have done now.

PS. a set of .2tt I/C's would be a nice addition so to keep everything as safe as possible in high temps. At @ $1K they are a cheap investment.

 

I would be very careful about any mods on a 997.2tts. Porsche has made this car mod-unfriendly IMO.
Honestly, the car needs nothing. Folks on this board have dyno'd a stock tts at 480whp on the same dyno where a 997.1tt yeilds around 380hp at the rims, that's more like 560hp at the crank....stock
Plus, the pdk is very limited, as is the ecu. The minimal gains are not worth frying the warranty on a 160k car with a potentially fragile, expensive transmission.
My only mod to date is limited to a gt2 alignment, and this car is considerably faster than my old blue car.
Jmo, sometimes less is more.

 

I'm inclined to agree with you here Chris. The new car is so fast out of the box. Outside possibly adding an EP to enhance the note and add to the down low there isn't a great deal you're likely to achieve without risking some sort of damage or premature wear if its a Pdk. Adding an AM tune with power along the same lines of the oem tune of the TTS shouldn't hurt though if the car is pdk. I'm quite sure Todd K would have developed a tune that gives full consideration to the constraints of the PDK box. A .2tt with a manual tranny would allow a few more opportunities though .

 

Europipe!

 

You have two of the most wanted Porsches and Im sure you will enjoy them once they return from Champions.

Can you elaborate on the downside "the chatter you will hear at idle"? How annoying is it?

 

The LWFW will give you a chatter at idle that sounds like a bolt is loose inside. It's annoying at times. It's especially loud with the AC on. Sometimes you get some people make comments like, "hey, sounds like something is broken on your car".

I have gotten used to it and the quicker throttle response is well worth the trade off for me.

 

It's annoying beyond belief IMNSHO ... Sounds like a box of rocks in the tranny getting all crunched by the gears. Exactly like that.

 

bob (bbywu) posted a video of this and even on youtube quality the chatter was fairly obvious. Ask nicely and maybe Bob will point you to the video.

 

I dont hear the chatter? However it does hit gears hard when set on Sport Plus. I guess it may be aftermarket clutches?
My Panamera however is smooth as silk in any conditions.

BTW: I did add a tune to my TT Panamera and gained a nice 60 WHP. I am right under 9K miles and no problems at all.

 

Hey JmanE55, give me a shout when you decide to do the Air Intake and Exhaust, and I will work up a nice member package deal for you. I would do the Mufflers and Headers to let the Turbo come on sooner and faster, but also make a sweet sound. The Mufflers with Sport Cats will make about 25+ HP and the Headers will also make an improvement depending on the application. We have a 2.50" exhaust setup and 2.75" setup depending on your needs. The Air Intake will also make a few more HP overall but make 15-20+ in some areas of the RPM range. Let me know if you have any questions.
Thanks,
