Carrera T + more power = the perfect driver's car?
#16
It should be noted of course that these parts are designed for any non-GT 991.2 911 ... base, S, or GTS. So it makes it extremely enticing (for power junkies like me) to do something like buy a base Carrera and spend the extra money on crazy GT2RS-like power ... for a lot less than a '2RS!
Also - the prices on the parts are very reasonable for the level of quality, engineering, and performance ... Porsche tax not applied!

Id be interested to know how it puts the power down? I'm trying to keep mine 'sensible' at 500PS and with the stock T turbos lag should be minimal. My 700PS 991.2 2RS struggles unless its a hot summer day and the tyres are cooking, it steps out all the time on a cold day and is less usable/enjoyable as a result.

First gear I haven't even bothered to try full throttle to redline ...
Boost by gear would be fantastic, but I don't think the stock ECU is capable?

It's definitely traction limited in the lower gears, especially on anything less than a perfectly dry surface. I'm able to do a second gear pull to redline at full throttle on a dry road with warm tires without breaking traction, but it definitely feels like it's on the very edge of the traction limits ...

The whole point of a Porsche is to have all the traction possible.. While I'm not at 700hp I still have an unusable 1st gear on stage 2 and I'm beginning to spin 2nd.
If I were you I'd be eyeing down matching or beating a 720s. You need first gear.
Love your build so far.. I like your style. All action.

Yes, you can get the sport aero package with front fascia and mini-ducktail. Not for me as I don’t want lower front clearance and I like the clean Carrera lines. But are there still changeable T allocations?

Carrera T + more power as perfect drivers car: 991.2 GTS coupe with MT, SPASM and the appropriate options also not a bad way to start...

Just curious, any consideration given to other engine and driveline limits? Bearing loads, piston ring sealing, oil flow and cooling, transaxle and clutch loading?
From 370 to 700+ is a big step.

I'm told the weak link are:
1) Traction ;-)
2) Clutch
Which is another reason (in addition to preferring a linear power delivery) why they deliberately limit the torque 'curve' to be flat through the midrange and not go for the typical turbo tuner car midrange torque surge.
Minus the slight change in turbos, the engine in the base Carrera, S, and GTS are the same ... so we know it can safely handle 450 without breaking a sweat ... and there is typically a lot of headroom/margin of safety from stock. Although another 250 hp on top of that is still a significant bump, no doubt!
That said, there is no free lunch and clearly the extra load will put extra strain on components and potentially reduce their lifetime ... I will absolutely be placing the car on an accelerated maintenance program and bringing it back to BR Racing on a regular basis for fresh fluids and checkups! It's probably worth having the oil sent off for analysis as well which I will likely do and share results!

Congrats! Went full bore and I love it!
How are you reading above 22.5ish psi if that is the limit of the stock sensor? Did bbrr replace the stock sensors or add an additional boost sensor? Are you sure that isn’t total pressure, as in you have to subtract standard pressure first to get actual boost pressure?
please be the first to go get some good 60-130 times with those M660’s. Dragy device and go!!!
excited for you as that is such a great project and know will be a blast for years to come.

The AP has a 60-130 timer, but I don't know how accurate it is ... I guess I need a vbox!
