AFAIK they're pretty similar sizing to the 991.2 TTS. They max out at about 750whp on racegas/meth IIRC.

I think they are bigger than that, I recall reading something about them eons ago, can easily support 800hp tune, more fuel than a tts as well.

Here is a “ballpark” based on different Porsche news releases over the years. They indicate base measurement and not tip to tip. As long as that is true and Porsche is consistent, this is a reasonable indication of size. Obviously, billet vs not, scroll design, AR ratio, impeller, exducer design, etc, etc etc play major roles. But this is relative.

It amazes me that dead struts plague just about every Porsche sports car after 5-6 years of use, and that it's been true for more than a decade now, maybe longer. One would think that Porsche would have addressed that since the German-made OEM struts all seem to have extraordinarily short life-spans. I've never had to replace hood, trunk, or hatchback struts on any other type of vehicle.

When I purchased my CPO '14 991.1 TS, and went to load some items in the frunk for the first time, I was whacked in the back of the head when the lid fell. Fortunately, this forum educated me quickly on the very inexpensive (usually Chinese) aftermarket replacements and how stupid easy they are to replace.

Replacing the frunk lid struts is actually easier than replacing some wiper blade designs.

I must have gotten lucky so far. I'm sure I'll eat my words shortly after typing this, as that's how life works.
Mine have lasted my 4 years of ownership so far. Not sure if they're stock or not. Never looked.

Did my 17-4s my 18 Panamera Turbo and now this car. I didnt think about until I noticed the frunk was slow to go up. Once it gets colder out it would really be noticed so I looked up my purchases on Amazon and ordered them again.

Maybe they were replaced before you bought it 4 years ago. Look at the label, and if they are OEM, you'll see "Made in Germany," based upon the weak ones I replaced. The old ones were so bad that at full extension, the tiniest bump, or puff of wind would cause the lid to fall.

The $20-something replacement struts I bought are significantly stiffer, and were ordered from Amazon (link below):

My '02 996 turbo struts were good after 18 years and 158,000 miles! And they were used a lot, as I dailyed the car to my office 8 months of the year and used them at least twice a day, plus weekend trips. We'll see how the 991.2's hold up.

Maybe, it's a 991 thing. Parts suppliers for all OEMs routinely change over time.

I had to replace the struts for the front bonnet on my 996 C4S after less than five years. It’s a quick, easy job.

Seems as if a gt2rs turbo upgrade for the tts would be pretty decent.

Ahhhh, dare to dream....

Same on my 996, I used the Rennkit mechanical ones, very clever design and will last for ever.
