SCCA NASA guys-- need advice!
We are building a C5 for a customer and need to narrow down where the car will be classified before we proceed with the build. We want to give the customer opportunity to run both NASA and SCCA.
Car will at minimum have fuel cell, lexan, brake upgrade, dry sump motor. If I remember correctly those changes eliminate SCCA T1 as an option. Is ITE the next step up, and am I correct in assuming the car will get thrown into there, or is there another option.
I don't know much about NASA at this point, but we are going to shoot for ST2 class.
So here is where it would stand-
SCCA - ITE
NASA- ST2
TCC- ??
Thanks Chris

Unless things have changed, ITE is a regional class, which will take a lot of the fun out of SCCA. I don't know about STO, as I've pretty much abandoned SCCA. However, if STU/STO are national classes, that's great to know.
As said, the NASA classes or much clearer. "anything" goes, pretty much, and you are classed by rear-wheel power to weight.
Approx numbers for a C5 race car.....
ST2 up to around 375 rwhp
ST1 up to close to 500
STU beyond that.
My "blowed-up" ST2 car is pretty light, so my max power is only about 325 instead of the number above.

Hey Dave good to hear from you how have you been? I don't blame you for ditchin SCCA. Nothing but politics when we ran in it. What if the car dyno's at 390 or 400? Do they weight penalize you?

NASA is hp:wt ratio
ST2 8.7:1
ST1 5.5:1
So lets say 3201 with driver at 400 rwhp = 8.0 which the low end of ST1.

SCCA STO (old BP) would be the big bore class for ex world challenge GT and similar cars.
Different SCCA regions have different classifications such as ITE, ITO that could be a fit as well as the catch all SPO.
The V8 StockCar series that runs in the south and east with SCCA and PBOC has a new class for 2009 called V8 GT-2 for ex World Challenge GT, SCCA GT-2, Koni Challenge GS, NASA ST2 types and similar.
We have a ten race weekend schedule running at Sebring, PBIR, Road Atlanta, Roebling, CMP, VIR and Daytona.
Your six best races (2 races per weekend) plus double points at the ARRC determine champions.
check it out at www.v8stockcar.com

To be competitive in ITE you need lots of HP and probably a splitter and wing. So that puts you in ST1 in NASA. To stay in ST2 you should shoot for a broad torque band to squeak in under HP/weight limit and have good drive off the corners. Will this be an LS1 or LS6 or...?

My Customers are running NW and Oregon SCCA and Conference, ITE and SPO. Very competitive in ITE not so much in SPO. SP is usually for cars that are tube frame. One car was bumped from ITE for using a different trans in a C4. Seemed the Porsche guys found a loop hole a few years back. Since then it was corrected to allow the Cars from Speed Challenge to run. Check with local region officials to clarify or have the Customer call them.

an unmodified LS1 is under powered for ST2. a Stock LS6 with minor mods fits very nicely into ST2. Mildley or highly modified LS6s are under powered in ST1 and over powered in ST2.
A stock LS2 may fit in ST2 depending on HP and cars wt. Even a mildly modified LS2 to 400 rwhp puts the car in ST1, but may be under powered for ST1.
Even if you use a car at 3300 lbs ( race set up, fuel and driver)
3300 / 8.7 = 379 rwhp would be NASA ST2
but 380+ rwhp pushes the car into NASA ST1
NASA ST1 cars are in the 500 to 560 rwhp depending on the cars wt.

TCC2= ST2 rules
I believe TCC1 = STO or U (check but I believe)

Guys great thread 
I am looking at buyin a use ST2 car but was wondering what the brake restricitions were? I would like to run my Stoptech 380mm 6 piston fronts with the Stoptech 355mm 4 piston rear? Any advice? This might also help the strater of the thread figure out what class to be in.
Thanks,
Mark

For the most part ST1 guys run SU with the Stock cars.
Races at Road Atlanta ( NASA-SE ) tends to have ST1 cars show up. At other races those few ST1 cars will run SU.

When you say they run with the SU does that mean that they are treated as the SU or do you mean they just run at the same time? Just curious. Wasn't the pfadt car an STI car??? Seems like an easy class.
