I am thinking of trading in my 997 Cab on a new 991 Cab. I read about the Power Kit but when I met with the local dealer last week he said that it was not currently available. I just went on the Porsche website and played around with a build - it is now an option. $17,800 with a 7-speed manual transmission.

It really is only about $13K because this option includes the Chrono and Sport Exhaust - both of which I would get for sure.

So, what do people think: $13K for 30 more HP and some cool carbon trim in the engine compartment?

Need to see the curve where the 30 HP available. If only at peak RPM then not a good idea.

 

There is another thread here or on reenlist about this Hp being supplied at peak power with no accompanying low end torque

Somebody was kind enough to post the curves on Rennlist - you might want to have a look. I'm sure there are much better ways to spend the money.

Completely agree!!

 

Yah skip the power upgrade, wait for the 991 Turbo of GTs. Spend the cash on better rims like HRE. PIMP

 

+1. And even if you want to go down the engine performance route, you'll get better results when more aftermarket options become available.
If you are a track addict and are going to redline the car a lot, you may still want to consider the performance kit though.

 

It doesnt sound like that great of a deal to me. Id go for Ceramic brakes before this

 

If looking for more hp, I would wait for a more powerful 911 variant. The powerkit does not seem worth it. But if I had unlimited money I would go for it.

 

He's looking to go faster and you suggest something to stop quicker.

 

Thanks for the input, I was on the fence. Definitely going to pass on the power kit. I am going to meet with the dealer today - I might post my proposed build for comment.

 

Steps to faster lap times: 1) driver's ed; 2) better tires; 4) better brakes; 5) better suspension; 5) reduce weight; and last, 6) more power.

 

I don't think he stated he wants faster lap times. If so then brakes could be an appropriate recommendation. It seems he simply wants more power, hence the question.

 

Actually, the PCCBs reduce unsprung weight and will add some quickness.

I will stand on my soap box and beet my drum for the effects of the PCCBs.

I took my RS60 out yesterday for a jaunt and the only twisty road I could find handy is a bypassed highway that hasn't had maintenance for 30 years. The lower unsprung weight allows the wheels to better follow the surface and the grip is increased on this type of road. They also seem to be the best modulated as any breaks I have ever felt. You can go write to maximum traction and feel every bit of grip available. In addition the lower weight shows up in stopping as you have less kinetic energy to overcome from the rotational effect of the breaks.
