Here's my current breakdown of points at 3280 pounds min comp weight and using TTB* starting class.. you can spend up to 39 pts and still only go up 1 class... B* +7 Nitto 275's +8 Weight Redux 20 lbs +1 CAI +1 Exhaust +5 SRM +3 LSD +3 Brakes +2 Shocks/Springs +5 Wing +4 TOTAL = 39, so class = TTA And if I had TTA starting with 3150 pounds min comp weight and TTA starting class, using Nittos Nitto 275's +3 (TTA std size is 295 so get bonus there) LSD +3 Brakes +2 Shocks/Springs +5 Sway bars +2 Wing +4 TOTAL = 19, so class = TTA (can add no more than 19 to stay in class) The benefit would be that I could continue to make engine mods so long as I stay under 320whp and also drop ~150 pounds. Would also add back sways. Alternatively, could forgo wing and sways and spend those 6 points on tires... could run 285 Hoosier R6's for example |

Thanks for the explanation, it is much clearer now. I would say the R6's trumps the wing (more grip at all speeds beats more grip at high speed) but it would be nice to keep the sways. That's the one thing that made this car so much better in the corners.

Tend to agree with you, Chris. Especially for the tracks I run where we spend 80% of our time below 90 mph. Plus it is super easy to take the Aeromtions wing on/off.
I find it very interesting how Nasa decided to base class this car... The base model is a TTB*, the sport is a TTB**, and the Nismo is TTA*. I had special permission to make mine a non-sport and take a +3 pts for the SRM, given I had swapped the brakes etc. The old Nismo was TTB vs new one at TTA*, so basically it moved up by a full class plus a "*" (46 points). That's like saying that a 370 nismo will post the same time as 2008 Nismo with 315 Hoosier R6's, sway bars, and 20 points of power / weight mods... Seems ridiculous to me! Also, have a look at the base classes for all these "TTB*" cars... Car Class Base Weight HP (mfgr) Weight / HP Corvette C5 (inc. FRC w/o Z51) B* 3246 400 8.12 Mercedes SL55 AMG ('03-'06) B* 4280 510 8.39 Mercedes E55 AMG ('03-'06) B* 4087 469 8.71 BMW Z8 B* 3500 400 8.75 Ford Mustang Cobra R ('00) B* 3590 390 9.21 Porsche 996 C2 (3.6L)('02-'04) B* 2959 321 9.22 Mercedes SLK32 AMG ('02-'04) B* 3220 349 9.23 Lotus Exige ('06) B* 2015 218 9.24 Porsche 993 RS 3.8L B* 2800 300 9.33 Ford Mustang Cobra SVT ('02+) B* 3665 390 9.40 Audi RS 4 (4.2L) (AWD)('07) B* 3957 420 9.42 Porsche 997 Carrera ('05-'07) B* 3075 321 9.58 Nissan 370Z (non-sport) B* 3300 331 9.97 Ours has by far the worst weight / power ratio... And remember the 370z Sport is a TTB** and the nismo is a TTA*... TTB** includes the AWD Evo X MR and TTA* includes the current Lotus Exige S, Ferrari 355, 2004 Corvette Z06, and Porsche 996 Turbo. Basically, we get screwed in NASA TT! lol It'll be interesting to see if I can make this car win in TTA. At some point, I'm going to move back up to TTS and hopefully that'll play to my favor - given it takes all this base class BS out of the equation. Last edited by travisjb; 10-03-2010 at 05:32 PM. |

Damn Travis, the car looks amazing and sounds like it performs well too. Car has come a long way and looks like all that hard work has paid off. Enjoy it now. I took mine in a different direction since it was never intended to be a hardcore racer, but sometimes I wonder what if, lol. Gonna look into doing some trackdays now that its finally getting cold again.

I haven't checked the dust boots lately and not sure if we swapped them out when we put the brake cooling in so don't know if it is going to keep them from suffering the heat... I can tell you I'm getting no fade and no ice mode, so happy about that! Quote:
Your car is coming along great! I continue to follow... glad your SC setup is working out If you want a hard core 370z just for the track, check in with Jay! I drove a ZR1 today at the track. Man! Serious power... still like the Z better though! Last edited by travisjb; 11-14-2010 at 10:53 PM. |

Looking good Travis, glad to hear you continue to make such huge gains each time out.
Is Richard ready to sell his fuel tank modifications? Is it possible/safe to ship a fuel tank across the country?

thanks. wish he would come on here and post! I think it's ready to go but that's going to be his call... he answers his phone... re shipping, yes, but he's creating a kit so you don't have to ship anything!

Had the car dyno'd today for NASA classing... fortunately, it came out just below 300whp, which means that I'm all set to run NASA TTA at 3,100lbs competition weight! So now I have sufficient points available for:
+3 Nitto NT01 275 series all corners +1 Modified LSD +5 dampers/springs +2 sway bars +2 brake calipers +4 rear wing and two points left over for something else... this is exactly the outcome I needed... last time I ran exactly this setup but carrying nearly 200 pounds of ballast... I'm hoping that by dropping the ballast I can make up the 0.5 second between me and first place... we'll find out on 27 November |

I am surprised how much you can add, and still remain in TTA...that's great news indeed. Let me or Ryan know if you need any help with things....or a bigger Forged decal.

Need some help/input...
Working on custom rear diffuser for my car... the evap canister... the emissions charcoal canister located passenger side tucked just inside the rear fascia... it is in the way of the diffuser... can I ditch that thing? anyone know if it is going to throw the computer into fits? alternatively, I could relocate it... do you think it'd be a fire hazard to move it into the inside of the car in the hatch? thanks |
