Just asking in general who has done what to gain 500, or close to it in the 2.9. That is where I would like to be. The COBB tun has me around 420 to 430 now.
is this a pure turbo or in house development?We plan to develop a turbo kit for the 2.9L engine but we need to do testing. We're hoping to pick one up in the future or find a client who is interested. We think close to 500whp is possible on the 2.9L but needs further testing.
We've made ~450whp on the GTS with just the Cobb OTS, F6 Intake and 200 cell downpipes.
If anyone has interest in volunteering their vehicle, we'd need it for a couple of weeks in Orlando, FL. We have the turbo sizing figured out but need to confirm fueling and torque delivery thresholds.
You are right. Nobody knows the actual drivetrain losses and it doesn’t really matter at the end of the day since all that matters is what makes it to the wheels. AWD drivetrain losses is higher than RWD though. More moving parts means higher friction.usually AWD drive train loss is around 15-18% on average. rwd only is around 20-22% and fwd it's 12-15%.
we can probably guestimate, but dunno if that makes us look better or worse =P
We haven't found any that work on the Macan.@Jon@Flat6Motorsports Have you guys tried any turbo inlets from an RS4/RS5 like this?
Guys, if you can pull off those numbers without modifying the down pipes and do so in a reliable way, I might say the risk to the warranty might be worth taking 😁We should have our first upgraded turbo 95B.2/95B.3 on the dyno later this week. Car feels strong, I'm hoping for 470-490whp. It would be nice to get this closer to 600HP at the crank. We've found the downpipes make a big difference but they introduce a raspy mechanical buzzy sound that I don't think too many folks would be happy with. We'll be testing with stock downpipes. More info and analysis coming soon!
Awww, come on…… I only have an S 😁That said, I cannot imagine there are that many who need/want more than the stock 2.9L V6 has to offer, let alone what COBB stage 1 brings to the table.

how is the turbo replacement test going for the GTS?I can confirm at the dealer level, even with the tune installed, they can't see any evidence on their PIWIS tester. Most dealers don't care. I suppose if you had a reason for a powertrain warranty claim, perhaps they would care but certainly a risk worth taking IMO. I always tell folks to weigh their own risk appetite. It's very subjective. There is no wrong or right answer.
I've never been one to hide anything personally, I don't believe others should bare the consequences of my decisions. That being said, US consumers have very strong rights, Porsche would need to prove an aftermarket part caused a failure to deny a claim. We still haven't heard or seen this happen outside of the transfer cases which Porsche acknowledged an issue with and extended the replacement warranty. I believe the concern to be overblown but that's just my opinion.
I don’t think there are many people who think the ‘23 S is a “dog” but a little more juice is a little more adrenaline. That can’t be a bad thing unless the warranty devil comes to play.I have not driven an S with 2.9L V6, but I would venture to suggest I could not tell the difference in HP/Tq from the GTS
Conversely, my wife has a 21’ S and COMPARATIVELY, it is an absolute dog . . . she loves it nonetheless.

I understood you weren’t talking about the 2.9 engine so I wondered why you would think there would be so little difference in the S and GTS 2.9. I haven’t driven the new GTS for comparison. It’s not so much the numbers but the seat of the pants feeling that might be a tad more rewarding.Not sure if you misread my post?
I stated doubt as to whether I could tell the difference between a 2.9L V6 S or GTS (22’/23’)
My wife has a 21’ S which does not have the 2.9L V6 . . . and is a complete ‘dog’ compared to the 2.9L V6

Because the 22’/23’ S/GTS have the same engine and, despite slightly different tunes, I doubt I could appreciate any difference when it comes to Tq/HP output.. . . I wondered why you would think there would be so little difference in the S and GTS 2.9.
Finally a "real world experience" that can provide us some input!I went with the GIAC tune on my '23 S. It feels like close to 500hp based on my experience with my other previous vehicles (highly modded 2016 Audi S4). I'll get a Dragy done on it at some point.
Got it through Porsche dealer. Warranty still valid.
