Porsche's Best Kept Secret - 991.2 Carrera?

[@christianchekroun4424]

I couldn't be happier with the work Jon and his team did for my car. That is my car in the video and I waited about 3 months to get an opening in their schedule to have the work done. Jon also lowered it, had an alignment done and detailed the car before I picked it up. I drove it back to South Carolina. I got better gas mileage, it stayed cooler and is an absolute BEAST on acceleration. I think it is time to upgrade the brakes!! I couldn't be happier with the work done and highly recommend Jon and the team!!

[@roybatty1899]

What was your total cost?

[@joeracer302]

They need better brakes with stock power. I love my Carrera T, but the stock brakes I could easily overwork on downhill canyons or track sessions. Arguably I’d say the downhill canyon can be the most demanding. Once I added Sport Cup 2’s I quickly found the extra traction led to a combination of higher corner speed resulting in higher end of the straight speed coupled with additional traction for braking then meant the brakes got overworked even more. My next steps, I’ll be adding more brakes before I even think of power. Just my preference for how and where I drive (95% SoCal canyons, 4% around town, 1% autocross/track).

Hey Jon, I can confirm that, it is a very good base with a lot of hidden performance. I have the 7-speed manual Carrera T, with headers, plenum and all the mods you recommended (I still run catalytic converters from Akrapovic); the car is at 617 HP now. But the real issue running such performance on our german autobahn or on the Nuerburgring is intake air temperature. At that level of horsepower, the turbos are still too small, and you get ignition withdrawal all the time due to skyhigh intake air temperature. That's really the week point. Currently thinking of adding a water-methanol injection.... Anyway: great videos!

[@Rockit181]

the catalytic converters may be responsible for higher IATs than if they weren't there, but of course you have regulations to worry about. Maybe some airbox work or additional ducting?

[@982porsche]

How does the manual gearbox hold all that power? Have you replaced the clutch?

It's better to get an S to start with because that gives you bigger 6 pot brakes and Porsche torque vectoring as standard, and the availability of rear axle steering, all of which were not available on the base Carrera.

[@stickofgod3132]

[@RamosRev]

In Australia PTV only standard in Carrrea GTS and no-one seems to specify S with PTV so I had to go GTS. Bigger brakes of the S/GTS are still not big enough. I am trying Brembo GT-S system with 380 front and rear. 991.2 Carrera is becoming known as a tuner car. Unfortunately in Australia local pricing policy makes them very expensive vs other platforms.

Correct, or just get the T which has all you listed (other than brakes).

Thank u for this vid, now I know the potential of my car. I need help. I have a 991.2 c4s that we absolutely love as our daily, so much so we bought a 10 yr warranty on it. How do I make it sound better? The turbo whistle and PSE is alright, but blasting through a tunnel sounds lame with nothing but air. While I am pleasantly surprised to read that u can put 200 cell cats and not trigger CEL on these cars, I don’t want to void any warranty. I want more flatsix mechanical Porsche sound, any recommendation? Nothing too crazy, I have 5 other screaming supercars for the occasions, but really hope I can add more volume and signature Porsche sound to this car without compromising warranty claims on drivetrain and emission parts, or compromise daily usability by attracting the wrong kind of attention

Good info. I recently installed a Cobb accessport stage 1 on my 2017 base 991.2 Carrera for 93 octane gas. According to the Cobb maps, if I am reading them right, I should have added 30 hp and 70 ft lb of torque. Does that sound about right? Thanks.

Hi All, I didn’t see any mention of headers being changed out. Any benefit there? I have a 991.2 GTS with Sport Cats, aftermarket headers, and PSE.

[@JohannSebastianOfficial]

That’s exactly the question I was going to ask

[@johnnygeorgopoulos4072]

How would the tyrannical state government of California know if you swapped turbos, tuned, ECT? The only thing I could see them potentially knowing about would be a removal of cats, but they make high flow 300 and 200 cell cats with better piping, which is where most of a power increase would come from in the exhaust end out of the 3 components (manifolds/headers, cats/downpipes, cat-back/muffler) followed by downpipes. Plus I'm certain you could find a local inspector that you could drop a couple 20's to to pass you 😅

[@stevenstanley400]

I have an 991.2 GTS how much HP would a tune add ?

[@Flat6Motorsports]

About 80whp and 125 ft/lbs of torque.

[@foesfly3047]

In Arizona we are subject to bi-annual emissions inspections. Pretty sure replacing cats with straight pipes would be a giant no-no. Is there a reason you chose Not to mention ‘high flow’ cats as a (street legal) option? Are they Not truly effective at reducing restriction? I already know I have a hard time paying more than $2k, considering their purpose.

[@Flat6Motorsports]

Yes, we have a very diverse and global audience and customer base. With the ever evolving regulatory environment we don’t like to discuss the issue as it may or may not be relevant. The focus on this particular build and idea was a little bang for the buck. The same can be accomplished with 200 cell catalysts but the power is reduced by about 10-15whp.

[@Flat6Motorsports]

It has an open differential. It doesn't matter much on the 911s in terms of grip/traction. It would show up more on track going 10/10ths and powering out of certain turns. We've tested over 700HP with the base differential and drives great.

The Carrera base is easy to tune. With GTS turbos and mapping you can go to 550 hp.

The standard spoiler is an open deck. It allows air to move from the roof down into the intercoolers. It raises at speed for increased downforce. There are also fans/vents which help allow the car to pull heat from the engine bay at idle/low speeds.

Being a N/A car they don't have the same potential with power. Opening up the airflow with an intake/plenum and headers/exhaust coupled with tuning will yield about 35-40whp.

Good luck getting the computers working. Seems like a nightmare. Probably easier to put a MoTec or some other stand-alone than try to get factory ECU to play nicely in another chassis. Those things seem to be tied into every subsystem on the car and anytime something is customized requires reprogramming to accommodate even little changes. Doable perhaps, but there are better ways to spend time/$ than dumping it into that kind of project. Can make a very nice 4.2L build for a 996 using a 997 based motor worked over by someone like Vision Motorsports.

Why don't you tell everyone how lousy the 991.2 is so the prices go down???

Totally agree. With all the BS Porsche is pulling by enabling speculators to control the market - jacking up prices on higher trims - this is the way to go. I have a 991.2 4s and was looking to upgrade to a turbo s. Well, the market is made up of - flipped cars that have been bought and abused for a thousand miles - then sold back to dealers at a profit. The dealers “certify” them and mark them up $60,000 to $100,000 depending on the model and config. No thanks. I’m planning to invest in my own car - which only has 6,000 miles on it - and basically get gts+ performance for a fraction of the cost. This is the cheat code that by-passes the Porsche rip off market environment.
