Correct me if I'm wrong, but didn't that car get dinged because the interior was not re-installed? If thats the case, then no wonder he got dinged in tech, no one's advocating blantant cheating. I'm just making the statement that a Grand-Am Cup prepped 996 is substantially similar to a PCA C-stock 996 and those have turned laptimes substantially faster (I'd consider 4 seconds substantially faster) than the time you cited at the Glen.
Grand-Am weighs cars dry without the driver as do most endurance series. So the 2950 is without driver or any fuel.

Can use 2 piece floating rotors
May upgrade the brake system (calipers, etc)
Cockpit adjustable brake bias
Camber plates that are not "pinned" as in PCA
Can remove the headlights
Different fuel pressure regulator & injectors
Aftermarket EFI
.030 overbore
Seam welding permitted
Must remove sunroof
Can weld the cage to the suspension pickup points
Can remove AC, radios system, Inner fender liners and interior
Different gear ratios allowed for some models
Any limited slip diff (not allowed at all in PCA for 996s as it was not an option)
Different flywheel
And I believe that the 2950 is with driver, no?
Btw, there was a grand am spec car that tried to run in C at Daytona. It was significantly faster than an 3.6L X51. Those computer changes can make a big difference. Bring a legal 3.4L 996 to the Glen and run 2:06s and I'll certainly be impressed. But I think all those little differences will make a fairly large difference in lap times.

Brian,
For whatever reason the GAC cars are quite a bit faster than the C cars. I would say its a combination of the cars, preparation and the drivers. The 997 that tried to run in C at Daytona was driven by a known driver that is good but not incredible and he just drove away from the rest of us. He was running 2:03s. I think I had the best time of the 20 or so C cars at a 2:06.35. Obviously he had way more car than the rest of us. Qualifying times for the last GAC race at Daytona ranged from a 2:01s to 2:08s.
I'm not sure why tech bumped the 997 but you could see from 20 yards that it was breaking many of the rules that the rest of us have to follow. Even if they don't have much impact. He had some carpet in back but not on the floor. No carpet in the trunk. Stock rotors and calipers but the master sure didn't look stock. etc. And boy did it fly. There is no way the engine was stock.
Anyway, I think that if they move the 3.4 to D, they (I) will do just fine.

Put Pat Long in my D class USA cup, give him Synergy racing to tune the suspension and blueprint the motor (and tune with a motec system) and the car would be right in line with GAC 3.4 996.

Gutted passenger side door (can only gut the drivers door)
Adjustable brake bias ****
No rear seats, all carpeting removed and no headliner
And tires that sure didn't look like DOT Rs.

Most club racers just show up and drive. I have a non adjustable shocks, and I run the same springs at every track. I'm not really sure that comparing a full pro effort to run-what-you-brung has much merit.

Hey Colin, why the heck are we sitting here making arguments FOR another fast car in our class? For the good of competition I guess!
we booked our Sebring flights last night... GIDDY UP

Here's what sprint qualifying would have looked like with the 3.4s in D:
Code:
Last Name First Name Best Tm Diff In Lap Color Desc JAKUBOWSKI ERNIE 2:08.671 +1.628 3 YELLOW S 06 CAYMAN SANDERSON TIM 2:08.989 +1.946 3 YELLOW S 99 996 MAZZOLA COLIN 2:09.759 +2.716 9 RED S 91 964 TURBO NIZBORSKI JAY A 2:10.629 +3.586 2 WHITE S 99 996 PRICE CHARLES M 2:10.646 +3.603 5 RED S 91 964 RSA OBLOW ED 2:10.662 +3.619 3 SILVER S 99 996 VETH CHARLES W 2:11.696 +4.653 11 WHITE S 91 911 T SCHENK DAVID W 2:12.260 +5.217 9 BLACK S 99 996 ROSE RICHARD C 2:13.919 +6.876 4 RED S 99 996 TURLEY II CORRY R 2:13.975 +6.932 5 YELLOW S 92 911 RS CS ARAKAWA ADELE 2:15.015 +7.972 9 BLUE S 95 911 C4 TAYLOR J WES 2:15.061 +8.018 6 RED S 96 993 LEVY JAMIE 2:16.557 +9.514 6 GREEN S 95 993 TURLEY CINDY N 2:17.791 +10.748 8 YELLOW S 92 911 RS CS
I think the only 3.4L 996 that I've lost to is Tim Sanderson, but even that has been close. He got me at Mosport & Daytona, and I ran faster at the Glen. I din't lose to any 3.4s at Road America or Lime Rock. Now, maybe with the 3.4s in D, there will be a huge inflow of fast drivers. Sounds like fun

Already have a set of Fikse FM10 Race Wheels as well as a set of CCW Classic wheels. Removing the Stereo equipment....is that legal? Can I just strip all that stuff out in C Stock? On the other hand, I would miss my motivational Van Halen before each race but I guess they will have to go if I can get rid of the stereo equipment. Also, not sure if I can remove the rear seats?? Anyone who can help with this, please pipe up. No, I don't have a C4 and yes, my C2 is pretty heavy. This is why you guys are here, right? Thanks for the GREAT reply! Definitely helps alot!

Rich and Carlos,
Before you head further down the very expensive path of building a race car, do either of you have any interest in mine? I'm considering options for next year and may end up with a cup car. I think it's safe to say it's one of the two or three fastest stock C cars in the country. Let me know.
