Doesn’t a stock turbo s do 0-60 in like 2.8?

 

Stock turbo S is like 2.5 seconds.

I tried a couple launch controls on my stage2 C2S but my worn pirellis didn’t hook quite properly, “only” got a 3.2

 

This is the one I installed. Made for the sport design or standard bumper:

ordered from Sweden and arrived two days later via DHL. An excellent set of instructions and perfect fit which was installed by an excellent Porsche service technician in a day. I don’t have before and after data, but do88’s data shows a drop in intake temps and consistent reductions with repeat runs. Another bonus, for me at least, was the elimination of the sound symposer which runs off the stock intercooler piping sound back into the cabin.

 

I have a base Carrera and am thinking about getting the M Engineering stage 1 tune. I understand it increases boost from 17 to 25 psi. Does anyone here know what the max boost pressure is on the Carrara S or the GTS? Those engines have the same internals as far as I understand, so I am curious as to what pressures Porsche subjects the motor to. I’d like to enjoy a little more torque/power, but most of all want reliability. I would plan to run the 91 octane map while using 93 octane fuel. Am I being overly concerned here?

 

The S and GTS can run just a few more pounds than the base model. The biggest problem with the base model is the turbos run out of "breath" very quickly and don't hold boost levels up top. The turbos are just simply tiny. The S and GTS aren't big turbos either, but they do flow more and hold up top more than the base. Big turbo options are available for both Base and S/GTS models that pull even harder.

The stock rods and internals will hold up beyond Stage 4, so you are more than safe to run these cars with the basic OTS tunes.

i’m running a M-Engineering stage 2 on a base 2021 Carrera - tons of power. It’s borderline too fast.. the boost really pulls in the low-mid range. Feel similar to a 991.2 Turbo. You will lose a piece of the unique base Carrera feel. But if it’s power you want, this tune brings it.

 

I am also close to pulling the trigger on this tune. If the exhaust valve mod comes online, I really want to hear the difference. If it makes me no longer want to upgrade the exhaust, this becomes even more of a no-brainer. I also want to run 91 tune with 93 gas with my S because I just don't need all that power and would rather be on the safe side.

Question for M-Engineering- Do both the 91 and 93 tunes come on the dongle and we can flash either one? or is it one or the other?

 

you can swap between any of them at your leisure. Foolish to run the 91 map of you have ready access to 93, IMO. Tons of headroom on these engines.

 

I don’t know why you would pay for this tune and run 91 octane if 93 octane is readily available in your area.

 

Guessing it produces less boost and will generate less heat because the engine is producing less power. Extra protection from detonation, keeps intake temps down, stock intercooler more effective etc. I'm not advocating that it's needed at all or saying the engine can't handle the 93 tune, but hard to argue there is extra safety factor by running the 91 tune no?

 

Can it be determined whether a lot of detonation is occurring from datalogs?

 

Datalogs can pickup detonation, knock, misfires, etc. Lots of information is available through the use of logging. We encourage the end-user to view their own logs, but we are also happy to do it ourselves.

These motors are overbuilt and can handle quite a bit. You are missing out on some power if you run a 91 tune with 93 gas in the car. We always leave headroom with our calibrations and margins of safety.

Thanks for the feedback everyone. Much appreciated! I will give this some thought over the weekend while I watch the NCAA tournament.

 

Hello, this is Steve from Germany …

If everything works out, I will be picking up my GTS Convertible in two weeks in Leipzig - hopefully no more delays cause of the war in Ukraine.

Do you have any info on when you will be able to offer maps for the GTS? Can I expect higher hp/torque figures? Does anyone have valid information on whether the hardware used in the GTS differs from the S-model? Or do I just flash the S maps?

Thank you!

 

I just need a GTS in the US who let us borrow it on the dyno to confirm testing results. We have yet to see one here. (holla if you got one!)
Hardware is identical to the S, so it's just a calibration change. Once we have this we will have a public announcement regarding GTS along with power figures.
