Usable and sustainable hp is more important often times than all out marketing driven hp.

I know it's given a huge advantage down low thanks to AWD, but GM claims their A8 shifts faster than PDK on upshift.
Car and driver ran 10.8 @ 130 in the Porsche 991TTS. 11.1 @ 127 in the C7Z06 A8.
991TTS 0-150: 16.5
C7Z06 A8 0-160: 22.9
My guess is the TTS isn't going to take 6+ more seconds for the last 10mph. The TTS beats the Z06 out of the hole with AWD and pulls harder up top.
Car and driver has their curb weight listed exactly the same @ 3588lbs.
Porsche has always done more with less when it comes to HP.

When you're comparing AWD to RWD, you typically can do more with acceleration, particularly if both vehicles weigh the same. Look at how well the Nissan GTR has done with lower horsepower numbers. I think its best time is still better than that of the 911TT on the Ring.

I'm not wealthy, so I can't afford all of the cars discussed in this thread. I can comment on the OT, and for me, it's true. I have over 650 HP, and it's more than I'm comfortable with in my C5Z. It needs racing tires to not be much more than a drift car.

What, no comment on why the Miata (or some other Mazda), relatively speaking, is a better car than the 911TT based on XYZ consumer survey?
Be consistent, man!

Because it's not. The cars are very closely matched with the TT/TTS having an advantage due to AWD if the track can hook and the violent 5500 rpm TT LC can be utilized. Otherwise the car will spin (on the street or at the track).
There is a big difference between quoting magazine times and owning both cars and being able to datalog each same day, same track, same time.

What mod's do you have on your GT-R? What year is it and have the mod's been on it since you bought it? Thanks!

There is a limit to using pump gas. If they'd start adding factory meth injection, they could have lots more horsepower from a lil 6 cyl. Turbo Buicks and their pushrod single cam engines seem to be fast on it. Boosted vettes do well as well on meth injection. I'm saving up for a Zonda...

Every magazine test I've seen, the Turbo S out traps the Z by 3 - 4 mph. I tend to ignore E.T. and 0-60 because I realize those are strictly traction limited.
But looking at the trap speeds, I would guess the TurboS is under-rated. Not sure how much more the S traps than the non-S.

Just curious, were those runs (b/w 991 and C7Z) done on that same night / track?

991 TTS, C&D, 10.8 @ 126 mph

Corvette Z06 (A8, convertible), C&D, 11.3 @ 126 mph
http://media.caranddriver.com/files/...onvertible.pdf
991 TTS, MT, 10.9 @ 123.7 mph

Corvette Z06 (A8), MT, 11.2 @ 127 mph
http://www.motortrend.com/roadtests/...06_first_test/
Not sure how the "Turbo S out traps the Z by 3 - 4 mph" unless you've seen magazine testing I haven't (which is possible). During one C&D comparison the TTS trapped a VERY fast 130 mph and the M7 Z06 trapped 125. Not surprising from what we've seen with the M7 cars (C7 and Z06).
I've also ran my TT same day, same track, same lane as a C7 Z06 (on DR's, which won't really effect trap speed). TT ran 127-128 mph, Z06 ran 130+.
TTS has ~18 whp more than the TT based on dyno-testing done by Champion Porsche. The TTS is also ~50# heavier. The TT torque curve is broader and it carries torque about ~500 rpm further than the TTS. Performance-wise they are nearly identical. Porsche claims TTS is .1 quicker to 60 mph.

If we extrapolate the data, the Z took 10.4s 100 - 150, and the P took 8.7s. Together with a 14 mph higher top speed, led me to state the Porsche being faster "bottom, mid, and top end".
I didn't know that wasn't the norm though. So with your other links showing much lower traps, I stand corrected. Any reason to the huge swing in trap speeds between magazines? Heat soak?

Not sure why that particular TT test car was so much faster than the others. Testing conditions? Ringer? Who knows.
They are very quick cars. I ran mine at an "Exotic" car shootout at OSW last summer in really crappy air. As in over 2000' DA. It went 10.8 at 125 mph and ran quicker than every GT-R there (modded and stock) except for my buddy's FBO E85 car with GT2867r turbos. There was a stock '15 GT-R there that day that went 11.3 at 122-123 mph. Very impressive cars.
But the A8 Z06's run very well too. If it was a heads up money race, not sure I'd want to sit next to an A8 Z06 in my TT. Here's the catch...the TT won't fall down as much in the heat as the Z06. But it also won't benefit nearly as much once temps fall.

There's no such thing as a low torque engine that's fun to drive that isn't on a bike imo.
I've driven 3 Porsche cars over the years and meh. The sound is deplorable, the torque gutless on the non turbo cars.
Now if Porsche, put a V8 in their cars that has this thing called torque...that'd be a different story.
Coolest Porsche I've ever seen had an SBC stuffed in the front.
The reality of the situation is, that Porsche, can't keep up with American, British and Italian offerings in the power department without making it a 1 million dollar car. There is no replacement, for displacement. Or # of cylinders for that matter.

When you don't have something, it's very easy to tell yourself it isn't "needed". I've done it myself.
I don't need that procharger, but hell would it be sweet.
I don't need that stripper with double D's - but hell would it be sweet.
I don't need a million dollars - but hell............
