I'm with Bruce too, there's no doubting that the GT3 is the most complete package but there's always the small matter of 680 Nm boosting a GT2 toward the horizon. I like that.

Besides I'd rather be a GT2 owner because, given the fact that I'm obviously rolling in the dosh, I've probably got a GT3 RS in silver with orange trim parked in the garage for trackdays too.

GT3 in white for me
btw: GT2's redline at 6500, but max revs is 6750

Oh my God, 6750? Really?

It's very very...well, unimpressive to say the least from a Porsche with the GT logo at the back.
For a Turbo it's no big deal (even if...it still is a Porsche), but for a GT2...

But it's a TURBO with tons of torque, no need to rev higher than that...

Well I expect more from a GT2.
But that's only my opinion.

But one must remember that GT2 has never been a high-revver by any means. The 993 GT2, nor the 996 GT2 never had maxinum redline's which surpassed 7K (the 993 had a maxinum redline of 'just' 7,000).

Since it's inception, Porsche has made sure the GT2 has stayed true to it's original form. Had they made the GT2 high-revving this time around, I honeslty would not have been as happy with the final result.

Nevertheless, I respect your opinion Raoul.

I don't think that people understand the differences between a forced induction engine and a high-revving normally aspirated one.

It's been discussed before; it is very unusual to find a high-revving turbocharged engine that pushes beyond, say, 7500 rpm. Which, in itself, is still HIGH for most engines. It's just that our frame of reference has been adjusted by a small minority of prominent engines in the M5, M3 and RS4 etc. Sure, there are a handful of exotics out there that rev to 8000 rpm too but this is also in very limited numbers.

To judge a 6750 rpm redline in a turbocharged engine as unimpressive vs. a naturally aspirated engine is incorrect. One must remember: In order to produce meaningful thrust at such high rpm, a turbocharger must be able to deliver the requisite volumetric flow. The penalty in such high-boost turbochargers is that low-end tractability suffers enormously - hence turbo lag. The concept of modern turbocharging is simple: deliver a low-end, sustainable slug of torque that ensure maximum acceleration anywhere in the rev range.

To understand this even more clearly, simply look at the in-gear acceleration figures of the GT2 compared with its siblings. It's actually slower gear for gear at certain speeds - a penalty incurred by virtue of the higher pressure turbos. Now tell me, how much higher do you want the GT2 to rev and at what cost to low-rev tractability?

Until one actually drives one of these highly boosted turbocharged cars you really can't formulate a concept of this particular driving experience - it's AWESOME.

Hard to choose one, they're all so awesome. For me though it would be the 911 Turbo. It goes way beyond reasonable capability for 99 percent of drivers (including me) and it more useable everyday than the either of the GT cars. Did I mention I can have my 911 Turbo without a top? Next would be the 911 GT3. The GT2 I can't even imagine what that thing is like.

Great post martinbo.
I know that a turbocharged engine does not need/cannot revv as high as a N/A. You have low-end torque, relatively low-end power, so no need to revv to search the hp.
This is very good in a Turbo, in an AMG, in fact this is awesome in almost every situation.

However, for me, a Porsche with "GT" at the back is a Porsche that is extremely sporty, made for the track, something extreme.
And unfortunately, the noise is not exciting enough, and a hard-core racecar just needs revving for me, it is a big part of the pleasure to hear the scream of the motor increasing and increasing and increasing, becoming more and more hign and metallic.

I don't say the GT2 is not sporty, I only thinks that a GT2 should not be such a low-revver. Maybe not high-revving, but 6750 ist just too low.

You clearly see in the videos, you just need to shift every 3 sec because you hit the redline very soon, barely the time to really put pedal to the metal that you have to shift...(and the gear ratio is only partly responsible for that)

Also keep in mind that, back in the time of the 993 GT2, 7000rpm was pretty high for a motor, even N/A.

This GT2 goes very very fast, it is insane, it pushes like few other cars in the world, it's as fast as the CGT, but I will always prefer the high-revving screaming concept of the GT3.

To each his own!

The point here Raoul is that both the high-revving NA and torque-slugging turbocharged experiences have their own unique appeal. Wanting the sportiest of turbocharged 911's to rev higher is, in essence, to not want a turbocharged 911! Stick to an F430.

Fans of the turbocharged experience want it for the very reason you describe: the maximum sense of acceleration, positively flying through the rev range, changing up quickly in rythmic staccatos of "whoosh-clack-whooosh-clack-whoooosh". The idea is quite different to that of hanging on the every last available 100 rpm (which in its own right is just as fun too) but to simply smash through to the maximum geared speed for that ratio and get on to the next. It's an experience that I am vividly familiar with and I absolutely love it.
