Just saw a post on IG that APR has a 718 S and is starting development. I have Cobb now, but I am very interested in what APR will offer for hardware and software. Can’t wait.

Damnit! I just posted in the engine section. Lol. I want an upgraded intake system. The factory one looks restrictive in several spots. Also a downpipe, headers, and turbo parts. I have a Base BTW. I’ve read the turbo is a K04 variant.

Awesome. We'll be looking into everything.

Calibrate my 991.2, I’ll have in Opelika the moment you say yes!

Shoot me an email with details on what you have: aahnell@goapr.com

Great news from APR who is back in the Porsche game. Many of you likely do not remember that APR at one point had a fairly robust catalog of Porsche tuning parts. Over the years their core focus became Volkswagen and Audi but they announced they are back in the Porsche tuning starting with a 718 GTS.

APR will likely find its largest market on the base 718 models with the 9A2B4 2.0. Why? Because that turbo is apparently a K04 which APR has a lot of experience with and it is not a VTG turbo.

That is not to say the 718 S and GTS 9A2B4 2.5 VTG models will not benefit from tuning simply that the 2.0 is the best candidate for turbo upgrades from APR.

We expect downpipes, intakes, intercoolers, and exhaust upgrades. The software alone will likely set APR apart from the rest.

Thus far, the 718 has been largely ignored in the aftermarket in favor of the 991.2 Porsche 911 models due to the 9A2B6 3.0 models all sharing the same motor and Porsche themselves distinguishing them with different software and turbochargers.

Hopefully the 718 9A2B4 2.0 and 2.5 finally get the push they deserve and if anyone can deliver it is APR.

I’m all in for one of their turbos. 450whp would be insane. I have Cobb right now, but I’m deployed and my friend is handling all the work. I would be interested in APR software for sure with a nice ball bearing turbo upgrade.

Hi Arin. How are the 718 GTS upgrades going.

Great so far. We have an exhaust system nearing completion and we're working on software too.

Any teaser photos or sound clips? I’m in the market for an exhaust and would be veryyyyyyy interested.

Not yet. We're still playing around with muffler setups and valves to see what we like best. I don't want to jump the gun and show off something that's not final.

Mate you guys doing a non-pse version as well?

What you also need to address heat soak. I have the 450hp kit from Ehresmann that is pictured in another post and it is absolutely fantastic! But, when tracking heavy on a shorter, technical track it gets heat soak and goes into limp really fast. We’re not necessary talking about outside temperatures of more than around 25c and the problem is present. However, on Nürburgring the speeds are so high that I’ve not been able to produce a limp mode. I also have an upgraded mid radiator with app 30% greater flow, but what we’re talking about here is not the cooling system but rather the intake temp. I also have friends with stock 718 GTS that get the heat soak, so it is not an Ehresmann related issue, it is a general intake temp problem. No one seems to work on an upgraded intercooler - don’t even know if there is room, so cooling with meth?

We're well aware of the potential heat issues on this platform and are calibrating around those. Game plan, sans hardware, may be to have multiple modes: Track mode (keeps IAT in check with the most power possible for the circuit) and a street mode that's more in line with what you'll see on the street (Less IAT since you're not at 10/10ths the entire time!). We're also looking into hardware, but I don't know where it will end up yet.

They aren't done yet so this is a teaser but Arin says we'll have a full graph soon:

Tons of testing so far. Lots of time on the street, dyno, road course, track, etc. Given this is our first venture back into Porsche in a while, we're spending a lot of time on it up front before releasing our first tunes.
