The torque delivery of the 3.8 is fantastic (better than the GT3) but it dies uptop and doesn't have the hp. Anything less than a WOT run to redline and the S will feel like it has bigger *****. If you push both cars the GT3 will walk away.

The S is a fantastic car though. I'm still thinking I may buy one.

an interesting comparison between 9997S and 03 GT3 can be found at http://www.track-challenge.com/main_e.asp

the 997S was slower on two tracks Nuerburgring 8:05 min vs. 7:54 min and Hockenheim 1:14.3 min vs. 1:13.2 min. it is interesting to note that the 997S had better slalom, lateral acceleration numbers and braking (32.3 m vs. 34 m from 100km/h-0 hot brakes), . the GT3 had better acceleration times. acceleration from 0-200km/h 16 s (997S) 14.8 s (GT3) a 1.2 s difference. for 0 - 200-0 Km/h times are 20,7 s (997S) 19,9 s (GT3) shrinking the diference to 0.8s
due to better braking of 997S.

based on this data a 997S w/X51 would be as fast or slightly faster thank the GT3. the GT3 has about 90 lbs weight advantage.

Dear MrBonus. the trap speed of 122mph (quarter mile of 12.15) was acheived at 15 degrees celsius track temp and with the rear tire pressure set to 28 psi and the fronts set to 39. all things are possible, just depends on the setup, same as tracking a car, the slightest chanmge in suspension setup can improve lap times significantly. However the point i'm trying to make is that the 997s is capable of putting out some great acceleration. for the test drive the pressures were the normal posrche recommended specs.

It's a race car that can be driven on the street. I drive it on the street all the time, no issues. "They're fun and all but it's just a DE." ????? Dude, you've got to drive one. This car is an extension of your body. You will never feel as connected to the road unless you attach wheels and an engine to your body.

Those numbers appear to be the Manufacture numbers and not from any independent testors.

I am surprised it made it around either track at all, with these tire pressure settings!

Listen, Man, I've driven real race cars I know what it's like to be connected to the track. My point about the GT3 is just my take on it, while I can easily afford one, I need things it can't deliver (back seat, daily driver including bad weather). I still say, get a cup car and be done with it.

I must agree with teflon jones...no way in H-E-Double hockey sticks are you getting 25-35HP out of exhaust and intake...

MrBonus

I don't care what the tire pressure or the temperature was. You'd need over 400 horsepower to the rear wheels to be trapping at over 120 MPH.

So are you saying that Porsche should stop building GT2's and GT3's because you should just get a cup car instead? Or did I misunderstand your last remark?

TT Surgeon

No man, they should build and sell whatever they want, and you should buy what you want. I'm saying for me, nobody else, it doesn't make sense. If I'm buying a car purely for track use, I'll buy a cup ride.
