Here's the 01 specs.. 370hp, maybe 320 WHP.. 02 and 03 went up 10hp each I believe:
Decades of experience of customer sport of the Porsche AG flow into the development of the near standard racing sportscar , the new 911 GT3 Cup.
This vehicle represents the new basis of the GT generation and has been developed in accordance with the 2001 Porsche Carrera Cup regulations. It is possible to enter this car in numerous races of the Porsche Club Sport scene as well as in the Porsche Pirelli Supercup and the Porsche Carrera Cup.
With 370HP (272kW) the 911 GT3 Cup is the strongest racing car in the history of Porsche´s single marque series.

A reasonably fresh 3.8 built from a 04' 3.6 dyno'd at 424 rwhp on the same dyno, same day....

For reference my '00 cup engine makes just over 350 rwhp, on a dynojet.
By 04 they are slightly different cams, longer rods, slightly different heads, etc. Every year there are slight changes and they keep making more power. A late 996 cup 3.6 (04/05) will make between 365-380 rwhp, stock. 424 is a bit high for a 3.8, but not unheard of. Probably has large tube headers with straight through exhausts, perhaps the later 997 cup intake plenum, etc....
Most of the new 3.8s in the 2010/11 cups I have heard are making somewhere around 400-420 at the wheels. The factory ratings are always slightly under (450 flywheel for the new 3.8).

I took the dive. Sold my beloved 07 GT3 street car and bought a 04 Cup. I will have my first scare at Roebling this weekend. Car is in great shape with low hours (thanks GP) , its 2005 specs with 3.8 liter motor and Motons. Right now its just for DE's with maybe CLub Racing in the future. I decide on this path because of 2 things 1) did not want to mess up a valuable street car with mods 2.) the cup is much safer. Last 3 DE's someone has trashed their "street" car. As I see it if I shunt the GT3 is worth half, If I shunt the Cup, as long as its not bad and repaired well no one cares, its expected.
This should fun if not somewhat intimidating at first. I know one thing , that damn clutch is a PITA....

I bought mine 3 years ago (2005) together with a friend and I know how you feel right now !
Let me tell you the feeling doesn't go away but after a few days on the track you do loose the respect for the car and that's when the real fun begins. You really need to push that thing and the tyres with a more aggressive line compared to Rtyres to get something out of it.
Keep the car on slicks, try and find good used ones. That's the neg side of the cup cars, tyres are key. After just a few tries you ll see what we all mean as their performance decrease is very noticable. You can't compare to R tyres that have a much more stable grip over their longer life time.
Also practice heel and toe ASAP if you don't do it already ! It's very easy on that car and you ll get used to it in just a few sessions. Definitly a MUST HAVE skill both if you want to go fast and to spare your trans.
Have fun!

Can I ask the obvious question?
I think for the price of this car there were several 997 Cup cars available. Is there any reason you opted out for 996 still? I know sequential gearboxes are expensive to maintain, but I would assume 997 cars have better suspension geometry and should be faster all things being equal, or am I wrong? With 3.8 the power would be the same as 997 cars, I'm just not sure how much the 997 car improvements are worth in terms of lap times.
By the way - absolutely beautiful car and I'm sure it's a beast! Just curious.

All I can say is trying to follow a 997CUP with a 996CUP is just impossible unless driving skills are very wide appart. The performance diff is THAT big.
And the power is not the only thing. The gear box makes a hell of a difference. Just looking at an acceleration log tells it all, the acceleration curve is almost linear for the 997 despite the upshifts. So a 996 with a 3,8 will still not keep up with a 997 in a straight line.
However the learning curve also looks pretty steep for an amateur racer and the 996 is more amateur friendly with the classic gear box and ABS brakes.

A 996 cup with a 3.8 will out accelerate a stock 997 cup (2009 and earlier) and will especially out accelerate them once you are into 5th gear (assuming gear ratios are stock for each car.)

All good points especially regarding the learning curve.
Not all 3.8's are created equal and if it's putting out more than say 400+ whp it should be faaster than most 7-cups with the exception of the 3.8 2010 cup. Now that car has insane torque off the corners and looks really easy to drive (mind you no ones offered their's to me yet)....

Yes it does....even uphill....
996 has more straightline speed due to better aero/less drag also...

True all 3,8s are not born equal
My line of thought was along the line that at more or less equal power, you still have to take into account the gearbox advantage of the 997 when it comes to straight line acceleration.
As for high speed and drag in 5th+ gear, fair enough, unfortunatly the track I go to regularly have very little 5th gear time overall... to short. On top of that mine is a bone stock 3,6 ! No chance

howdy all, I just saw the thread fire back up. My second track weekend was RA a few weeks back. Some random thoughts. Hot was an understatement. I have some peddle reorientation work to do for heal/toe plus my own screw-up’s. Tried new yokahamas and at my level they are good. Also tried to follow a Doctor in a 997 Cup who is also a pro driver. Do not remember his name. I can say yes the 997 will pull me on the back straight rather handily. Thank God for ABS, bad foot work and way too deep into 10A. after a cold sweat I also realized the car really will go that deep but that is not for me right now. Stability is wonderful compared to the street car. Transmission is getting abused by my misconduct, hope it lasts my learning curve. is there any way for me to shift a bit slower without shocking the engagement, seems the only way to not shock is as fast as I can. I know my heal/toe into 10A is poor and is killing my laps. I bet I did not have 1 lap that had clean down shifts, got to work on the gas pedal to bring it up and over more. Lap times as compared to the street 2007 GT3 at RA were similar to Roebling, 6 seconds cut at RA vs 7 seconds at Reobling. And yes I have a long ways to go to the cars ultimate potential only managed a 1:36.1 but for me that felt realy good. Yes the car is worth it even with the extra support efforts it requires.
