I think that depends where you are.
In London where the kerbs are high and the parking parallel, it is worth having the wheels insured.
Where I live now in rural Devon where the lanes are full of sharp stones, it’s worth having the tyres insured.
If I lived in Houston or LA, maybe not so much.

I think it's challenging to compare dyno numbers to PAG numbers. Dynos are known to be unreliable. Their usefulness is mostly in measuring gains after a modification has been made. Is 425-430 possible? Maybe but I'd be skeptical. I don't doubt that the car has more than the 385hp published.

Jon has consistently said that the base 911 engines are the most underrated based on multiple dyno tests, much more so than the S and GTS models. It's pretty obvious why Porsche would do this - creating more "value" by buying up and getting more HP. The car is quick, no doubt about it, and the base engine's flat torque curve does feel more NA than turbo. I still prefer the NA. Oh, and BTW, I bought a 2014 GT500 last month. It's my first time driving a supercharged engine. WOWOWOWOWOWOW! Talk about torque, instant torque, at any RPM. WOW.

Engine location is not the cause

What's Robbing Horsepower

Within the drivetrain itself, the primary loss sources are the differential and final drive, with further losses stemming from within the transmission, and in the case of AWD vehicles, from the transfer case. Within the transmission, as much as 30 to 40 percent of power loss can be attributed to the pump, with the clutch contributing another 20 to 25 percent. The rest of the loss within the transmission comes from seal drag, gear meshing, bearings, bushings and windage (drag on the gears caused by the gear oil).

When the engine is close to the drivetrain, everything mechanical, including the transmission, is closer and tighter together and sometimes has less moving parts. Compared to a front engined, rear wheel drive car where the engine is on one side, the axle on the other, and the transmission in the middle, rear engined and mid engined cars are far more efficient. Engine location is the cause. In fact, it's the root cause. You're addressing the symptom.

Congrats on another T! And i fixed it for you (flame suit on):

Function:
Manual
Buckets
Preparation for roof rack
90L tank
Bose
Rear axle steering

Race Tex steering wheel and shifter boot (I consider this functional)
Race Tex console with Porsche crest (carpet must match drapes)
Race Tex roof (as above)


Form:
White
Leather
Leather steering column
Mamba Green stitching
Interior trim in exterior color
Exclusive Design Tail lights

LOL. You haven't been to Houston in a while. The roads are an absolute catastrophe, its hard to believe. I've lived all over the world. Houston's roads at present time are the worst I've ever seen.

Houston's soil is clay-bearing "gumbo" that expands when wet and shrinks when dry. Periods of drought this year and in years prior have made the concrete slabs underlying the asphalt shift and force up to 4 inch+ (!!!) seams between lanes and at transitions. It's a horror show, legitimately hard to believe how bad they are.

I've already lost one tire when changing lanes in a spot that day T-1 was level and day T-0 was a 3 inch sheer cliff. I bought the $3,500/3yr tire+wheel protection package and don't regret it, if only for peace of mind.

It's interesting to me. I got my 991.2 T with the T package without leather and no RAS. Visiting rennlist pretty much every poll said those are two must have options so I felt like I made a mistake. I thought I corrected the sins by having both in my 992. It's only been a week but I realized those two options don't add any enjoyment for me, easily would've been fine without either. Kinda would rather have had the painted seatbacks in GT silver or alcantara roof liner. Maybe it's just a function of going from 991.2 to 992 but the RAS hasn't been mind-blowing like I expected it to be. In my EQS barge of a sedan it's great but in this application it's kinda been take it or leave it.

Thank you my man. Good point on the Race Tex. RAS is just not for me on anything but a track weapon. It's like PDK: technically better, experientially inferior.

The RAS was a much more important option on 991.2s and less beneficial on 992s. The 992s have the engine mounts moved 4'' further forward and the wider front end track gives it a much more planted feeling and less understeer. The quicker steering rack also helps agility on the non RAS 992. Having said that Porsche seems to have made more changes to how the 992T handles compared to the early 2019 992S PDK I briefly owned. The 992S felt aloof and lacked front end agility wheras my 992T feels much more resposive to steering inputs. Both non RAS cars and 10mm lowered suspension. The only real difference between both cars was the 992S was PDK( which I hated).

@Taffy66 Agree with most of your comments.
I didn't get RAS, but did get FAL.
But ironically when I order a 992.2 T I won't bother with FAL, but will be ordering RAS specifically for manoeuvring around my driveway.
We've recent obtained a 3rd car and trying to fit them all on the driveway in a way that makes entry / exit easy means I now regret not having RAS!

We usually see 360-370whp on the base model, 380-390whp on the S models and 385-395whp on the GTS on our dyno. It tells us the base model is underrated from Porsche. The S/GTS has pretty significant opportunities from a tuning standpoint (the larger turbos make a big difference up top) but the base model/T is no slouch!

I think it is a bit of a no-brainer to get either RAS and/or FAL for anyone who will benefit from them depending on where they live or park their cars. Can make the difference between gaining access to being inaccessible. Fortunately, my home/garage has plenty of room to maneuver so they won't benefit me personally.
