We explore the question of whether the 991.2 Carrera and it's potential is the best kept secret in the Porsche community. *Learn More About 991.2 Carrera Power Kits Here* flat6motorsports.com/pages/99...
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!!
@@GTRuppsala It will hang with the big dogs and sounds absolutely fantastic. It now sports Yellow BREMBO big brakes front and rear. I think it is just about perfect!!!
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).
@@Flat6Motorsports I do want to switch out those goofy, oval exhaust tips to chrome, round dual. But had a hard time finding anything online last night.
I have the same car without Sport chrono, or pse. I have everything you recommended and a few other plug ins. Currently on APR stage 3 e85 file and Im doing 600whp on dyno. The car runs amazing and loves the upgrades. Definitely a sleeper.
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!
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?
@@memyself5337No need to get emotional about a design. Both cars great, some prefer the stunning cluster in the 992 while others prefer the 991’s cheaper looking cluster. Both can look “soulless” if you hop into a Mercedes.
I’m laughing and enjoying this video because I’m an owner of a Mazda Miata NC with modified suspension. I’m a weekend canyon carver. The joke is that your impact tool from Harbor Freight has more torque than a Miata. The power numbers on these flat 6’s are impressive.
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
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.
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.
@@TheHoosiers2008do you know if the PDK version of the T has PTV? I haven't been able to confirm. I'd rather go manual but they run about 15k higher which would make the S the better choice in my situation
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. Is the BMC intake upgrade truly required to load a stage 1 or 2 OTS map? Do you recommend any other additional upgrades for stage 1/2 street driving (moderate occasional high load on street roads)?
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.
Just for reference the base 991.2 turbo size is 49mm, 51mm S, and 55mm GTS and the gts has a bigger AR. I was the first to have the pure turbos and on E85 the car made just over 700whp. Also I believe the pure turbos are 62mm's..
If I ever need to visit the dealer can I remove the tune? But must importantly is the foot print of the tune removed? Making it invisible, like it was never there? I have heard it will be found, but I wanted to ask you the professional
Yes, it can be removed and even with it on, it won't show up at the dealer level. Log flashing is stored deeper down in encrypted logs that rarely ever get analyzed, but assess your own risk.
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.
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.
This maybe a dumb question, but if you could get your hands on a higher mileage 14 Turbo S or a low mileage 18 Carrera 4S for about $20K less, which would you pick? I'm really torn because of the look and aura of the Turbo S, but thinking about long term and resale of a low mileage 2018 4S.
AWD drives like shit compared to the RWD 911. I guess different strokes for different folks, but my preference would be for anything RWD over either of those cars. The weight and front drive ruins the front end steering feel/precision to me.
@@derekwhoelse8359If he truly thinks that, he’s exaggerating. Back to back i prefer rwd, but the awd models feel nearly the same. They feel like they’re rwd from behind the wheel because the awd system works essentially the same as haldex does in a Golf and they’re heavily rear biased. Similar to a Huracan’s awd system or Bmw’s xDrive, they can’t send more than 50% to the front
@@PapiAndrey You know what you are talking about Papi. I had the rwd's and now the awd. Especialy with wet roads the awd is fantastic! Like you said, both feel the same while driving but you can push the car much more when wet in compare with rwd..
I’ve never heard a description of the differential in the Base Carrera. I know it’s Not the stellar Torque Vectoring unit. Would it just waste this extra power?
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.
@@micraw714 I am not sure, but I don’t have rear axle steering, it’s just rear wheel drive and a 3.0turbo. Great setup, the only downside is the sound is a bit muted because of the turbos. The sound inside the cabin is great because of the intake sound tubes.
@@TheNextCorner-original nice, thanks for the info and I bet it's a blast to drive! I drove a base and really liked the power band so I can imagine the T with the extra goodies is really good 👍🏼it's between that or an MT 991.2 S. Decisions decisions 🤔
@@micraw714 a PDK is also fun in manual mode, but I can imagine that a manual shifter is also fun to drive. I choose PDK for roadtrips and because it’s my first Porsche I like the super fast racetransmission and launchcontrol. Maybe next time I choose a manual for fun 🤩. I think both car are great. The Carrera base is easy to tune. With GTS turbos and mapping you can go to 550 hp. I personally believe 370hp flatsix turbo on rear wheels is more than enough, it’s faster than a Audi rs3 Quattro with 450hp.
@@TheNextCorner-original that's awesome, I used to have a 981 Cayman S with the pdk and I really loved that transmission 😁 seems like you really can't go wrong with either one!
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 😅
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.
What could I expect from a 991.1 Carrera c2 base for power upgrades? I feel mine needs a little bit more punch, especially in first gear. Tunes from my understanding only maybe add 25hp. What are my options?
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.
@@Flat6Motorsports Do you honestly think it’s worth it, would I notice the 30-40hp, which probably comes in at the higher rev range, when it seems laggy at the low end. I already have the Soul Sports Exhaust, headers next I guess - do the headers coming with the hi flow cats? Also, what tune would you recommend?
@@capitalexotics it comes down to preference on if it's worth it, many customers find it worthwhile. High flow cats would be a next best step. Tuning, I would recommend the Cobb Accessport.
@@Flat6Motorsports thanks for the replies, to someone watching your videos from the great white North, not Florida! I wish we had a shop like yours in my parts! You seriously made me question whether I should sell my 991.1 and get a 991.2 after seeing these incredible power gains! Damn, I could only imagine having 80% more power at the wheels. Let’s just say my wife isn’t impressed with the conversation… lol!
Need to? No. It comes down to preferences and driving conditions/objectives. This particular car did end up with some upgraded Brembo units. The base brakes are sufficient for street driving but for more overall balance or performance, upgrades are nice to have and make the car more complete in our opinion.
@@Notachancepoopypants feel free to email us at info@flat6motorsports.com so we can learn more about your requirements and help get you into the right solution. It can start with just turbos, exhaust and tuning. Many folks will add intercoolers if they are tracking the vehicle or live in hot climates. The chassis can handle a lot of power so it comes down to preferences on suspension/brake set-up but we'd be happy to help. We also have a helpful guide here to give you a quick guide to different power levels: flat6motorsports.com/pages/991-2-carrera-power-kits-by-flat-6-motorsports
@@thegrmcrckr488 Methanol is corrosive but when used in a performance setting it is a bit different. I believe what Matt is revering to is "water-meth injection". That is a fun rabbit hole to go down in terms of what it can do for performance without catastrophically hurting the car.
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.
@@Flat6MotorsportsOR MAYBE, you actually make an informative video about the 991.2 to show you know what you're talking about and build consumer confidence with your company. I look at this as just another shop selling shit bolt on parts.
