Default Will 450hp be Enough for 991 GT3?

Many are speculating 450hp will be the magic number for the 991 GT3? I'm wondering if that will be enough with the just announced Powerkit for the Carrera S? 30hp is no small bump...

Porsche Exclusive Unwraps 2013 911 Carrera S Powerkit with 30 More HP

Porsche’s Exclusive department has been fiddling with the 2013 911 again, and unveiled its Powerkit package that promises an additional 30 hp for 911 Carrera S drivers.

Porsche Exclusive has long been messing with Porsche’s already lavish, expensive cars by adding various interior and exterior features, but the 991-generation 911 Carrera S has one more option available. Porsche Exclusive calls it the Powerkit, and it’s a comprehensive set of mechanical and software changes that bump the C2S’ output from 400 to 430 hp.

Tweaks include new cylinder heads and a tweaked camshaft, a different intake system, and an additional radiator. That combines with changes to the 911′s engine control unit, the Sport Chrono package from the C2S that features dynamic engine mounts, and a freer-breathing sports exhaust system. Lest anyone be fooled into thinking you’re just driving a stock 911, Porsche affixes a special carbon fiber engine cover with the words EXCLUSIVE POWERKIT emblazoned on the top.

Porsche says the increased power ensures that the 911 C2S with a PDK double-clutch gearbox can get from 0-60 mph in just 3.9 seconds (a decrease of 0.2 seconds), and will top out at 191 mph, three more than before.

If you’re yearning for some more visual upgrades to reflect the increase in power, Porsche Exclusive also offers a new fixed spoiler that hearkens back to the ducktail spoilers of years past. If you’re looking for something more modern, Porsche also offers the Aerokit Cup package, which affixes a second rear wing over the standard spoiler and puts a body colored lip spoiler up front.

Pricing hasn’t been announced yet on the Powerkit or Aerokit Cup packages, but don’t expect the power bump–which involves much more mechanical work than chipping a turbocharged car–to come cheap.

This has to be GOOD news for the GT3. Porsche could not be that stupid to make the GT3 just and upgraded C2S AND only slightly faster.

I'm expecting some big news for the GT3. Flat 8 Flat 8 Flat 8 Flat 8.

it all depends what engine the new race cars will have ... which I suppose could be an 8 ...

I'd be a bit pissed if I had just bought an RS 4.0 to discover that it had been superseded...

I'm still "betting" its a 6 cyl, 3.8 or 4.x with bhp somewhere between 450-500.

Wait, so the thought is that Porsche will put the 4.0 on a pedestal and let all their competitors evolve while they stand still?

This Exclusive Power Kit will be the most expensive /costly kit to achieve a mere 30 more horsepower from any manufacturer ever ..... my prediction.

For any new perspective 991 GT3 buyers I pray the number is at least 525hp ..... 450 won't cut it

If the new car is significantly lighter I believe they could get away with "only" 450.

Just a few points to keep this in context:

1. The 997.2 powerkit developed 408HP. The 997.2 GT3 had 435; a difference of 27HP.

2. The 991 powerkit will make 430HP. Even if the 991 GT3 makes only the rumored 450 that's not a hugely different delta than between the previous cars. My guess is it will be a bit more than 450, but if it's not, we're not talking about a big change from the status quo.

3. I get the concerns about HP and the competition. I'd like to see Porsche up the ante, and I think they should. That said, I'll play the devil's advocate. The current GT3 RS makes 450HP. I haven't seen many complaints about folks wanting to trade theirs in because it's underpowered. Why is a new likely lighter-than-an-RS 991 GT3 with 450HP underpowered, but a current RS with 450HP isn't?

Just askin'.....

For the BHP game, Porsche has the turbo for that. I'm sure the GT3 will have more power in the 991 series but how much is still a big question. My bet is 465-505 range.

Totally agree Porsche can't lighten the car enough to make 450 fast enough.

Please refer to demand for RS 4.0.

That said, I'll take weight reduction over power gains any day of the week.
