homologation to the race engines.

You can modify the exhaust on the RS aswell.. The titanium exhaust on the RS is not that less restrictive than the regular GT3.. Lighter yes..

Funny how the same people on this forum just won't stop hating on the RS no matter what subject is brought up..

Porsche has a good way of presenting information. Remember how they were bragging that the GT3 has the same wheel bearings as the CUP RACECAR (and also the cayenne SUV...).

This is why I started the thread. I was confused by the marketing dept at Porsche, and I still am. I thought the only real difference is the displacement. I thought Porsche would pass on any other improvements they made for the RS engine to the regular GT3 as well, since there have been some engine failures.

Have a gander at the scanned-in article on post # 237:

Just in time

I heard the crank was an essential upgrade for endurance racing.

The only way to really know what's truly different GT3 RS vs. GT3 is to go into PET and compare part numbers. Somebody did this with the GTS vs. 911S.

The way they described the crank alloy it is most likely a vacuum melted ingot that is then re-melted in an ESR process. Extremely clean and expensive. The record keeping for every ingot is extremely well documented.

I agree. There is alot of confusion between what is "new" on the RS and if that means its new compared to the 991 GT3 or new compared to the old RS. PAG used the 991 GT3RS release to kinda "wash its face clean" after the 991 GT3 engine fiasco so much of what it says is "new" in the RS may infact also relate to the GT3.

In the past we have had a technical sales manual launch before the new car arrives. This is available for the 991 GT3 and GT4 but Ive yet to see mention or reference (or screen shots) of it for the 991 GT3 which is curious. It often has pictures and goes into details about the changes and is quite interesting. The PET however is the most accurate document in telling wether compnents such as the crank shaft are indeed different between the 991 GT3 and the RS (I suspect they may well be post GT3 engine recall!). Again, the PET is usually available before the cars are delivered. But I havent seen the 991 GT3RS PET yet so if someone finds a link please advise it here...

ido not understand buy porsche doesn't disclose a lot of info.
when i had 38 and 40 rs both on racks, theere were a LOT of difference that are NOT shown anywhere on porsche literature. and they two cars are way more different than the 200 cc suggests.

so dont just believe what you hear or see on paper

also, based on my exp in 7.1 to 7.2 gt/Rs, just b/c the PN is different doesn't mean tthe acutal item is different!!!!

The crank technology is from the 919 prototype - no homologation issues for the ACO prototype class. GT Class is different. Suspect that we will see the crank in the new 991GT3R.

Wasn't it with the original GT3s that the Porsche badge's were Stickers and not an actually metal badge?

For the 996 Gt3 rs correct!

Tacet-Conundrum

Wow what a way to save some grams. But Meh(!) whatever is clever for them. I didn't like the 996 with the fried egg lights but the 996 GT3RS has something to it. And most who have driven all the GT's will say that it's one of their favorite GT's due to the lack of driving nannies. Although Porsche has come a long way in 12 or so years with power and evolution.

I still say the most overall fun car I've ever owned was my street 996 gt3...thing was just beautiful to drive on the road or on the track...the 997.1 was so much less fun to me (though the 997.2 RS was pretty epic). Then again explains why I think the 991 is boring and while I enjoy having one, it definitely lacks the "egg"citement of my 996 lol.
