991.2 Base/S/GTS Modification & Race Track Prep Thread
#61
Thanks for advice gentlemen
seeing that gauge with no boost drives me nuts!
I'm going to take an Pdk one for a run tomorrow with my salesman ( they don’t have any manuals in stock) see how it boosts.
my friends 2018 GTS needed new turbos, from looking on the web I have found nothing regarding my question, I guess people drive them and don’t notice the 0 boost?
I did rev it hard and the boost gauge for a split second showed 3 psi, but a car that developed power at 1700 rpm should show boost at and over that?

After searching high and low I finally found a car to do our R&D on that should appeal to anyone looking for a track oriented .2 GTS with what will essentially be free upgrades when I go to sell it in 2 month's time.
It's a 2017 with PDK, 5 lugs, steel brakes and sunroof delete. If I can find a pair of carbon fiber sport buckets I am going to jump on those. More updates to come and tomorrow I should have a good dyno baseline.

Will be interesting to see what you do with this.

My goal is to before and after dyno everything we do so I can have a detailed upgrade report.

It's a royal PITA to get to the coil packs to get an RPM signal so my dyno appointment is this week. I didn't want to make two trips so I sent the ECU out to Cobb first so I can dyno the car this week with and without the tune. My initial reaction is that I'm absolutely blown away by the increased power and torque from the file. It's nuts. The car now feels like you're being shot out of a cannon. The power delivery is as smooth as silk and the car drives just like stock!

I have a 2018 991.2 GTS. And oh yeah, I'm gonna mod the **** out of it. First performance mod was IPD Plenum. Then I added the AMS Alpha Performance intercoolers, preparing for full Stage 3 COBB. Whilst I have the access port, I haven't sent my ECU away yet. I have MPSC2 on front already. Will do rear soon.
I am also looking at brake up grades.
I will be adding VEKTOR headers with white lightening ceramic coating. Akrapovic Sports cats. Next on list is the DSC Module. I also like their state of the art electronically controlled springs and shocks. (if not them then Ohlins TTX)
Then i was thinking elephant racing adjustable bars and spherical bearings, but I just see you have some as well. (Nice we will talk)
You know who I am, drop me a message to confirm. : ) P.S. Love your work.

As I am sure others have done, during the time spent waiting to find the 991.2 GTS, I began sucking up everything I could find on the internet about the 991.2 Carrera. The most repeated thing was "a 991.2 GTS with a flash will make unbelievable power" and will walk all over a GT3. 3 weeks ago the yellow car showed up but I had to leave town to attend the next round of Porsche Club Cayman GT4 racing so my guys removed the ECU and sent it out to Cobb and it showed back up Monday. They provide an RMA, a box with packaging to protect the ECU and insurance to cover it in the event that it gets lost. I flashed the car and was immediately blown away by the increased power and torque but I wasn't prepared for the numbers I saw this morning on the dyno. It's a hot day today in Florida and by the time I got to the dyno it was already 95F outside. I drove the car about :40 min south so it was already heat soaked when I got there. I did 2 pulls with the Cobb tune installed and another 2 pulls on the stock mapping.
All I can say is HOLY COW!
100 horsepower and 100 lb/ft AT THE WHEELS is pretty impressive from the base tune from Cobb. Soon I will begin tinkering and creating my own mapping. Next I will dyno the IPD plenum & BMC filter intake upgrade and then I will do the bypass pipes. Cargraphic is sending pipes with 200 cell cats and as well as catless because I want catless for the race track but I want to also be able to tell people how much louder catless is and how much power it adds, if any. The graph is attached below! If you have a 991.2 base, S or GTS and you want what I now think is by far and away the best upgrade for the money, you know where to find us!

Subscribed. Amazing numbers from just the tune is a hot/humid environment. Can't even imagine running that in the fall/winter cold temps here in the midwest. Wowza. Eagerly awaiting upgrade path developments.... Keep up the amazing work.

BGB - Any concerns tracking this car with a stage 1 tune? Adding a third radiator ? I moved from a 2018 GT3 to a 991.2 as I hated the attention I got in the GT3 ( AMAZING car though).. This could be best of both worlds if I think I can track the car.

I hope to be 100% successful in tracking the car with the Cobb Stage I flash but if i'm not, i will dial it back some; i want to do all cooling mods first and then put it on track because you will all want to be able to use that 100hp on the track, otherwise what's the point?

Thanks for the kind words! I normally cheat though and see what your location is next to your avatar but now i know who you are. I told you man...I think that you're on your way to having the most potent 991.2 GTS in the world. The car will need camber and it's going to eventually need dampers but i feel if i do that i'm definitely going to exceed my original plan to try and keep it under the cost of the GT3 because the GT3 has the coil overs, the split arms, adjustable toe links and the aero.,
Please correct me if I am mistaken, but I know the 991.1 GTS had the third radiator, I assumed the 991.2 also has the third radiator?
Tractive look to have the state of the art Coilovers. I am interested in those with the DSC module.
