LOL. Good thing we don't run at the same tracks eh? Just kidding, your car is plenty faster than mine. Good luck with the SC! I could have used one to keep up with my buddy's C6, he had 1 second a lap on me and it was all on the straight.

Wow, shocked you are going forced induction but will definitely be interested in your results. I know you are going to put the kit through some tough tests.

RCZ · 08-03-2011, 02:02 PM

^ The kit will be fine

its the motor we're all worried about

travisjb · 08-03-2011, 02:18 PM

I'm obviously betting that at <400 hp this motor will hold up fine for the kinds of events I run... 20-30 minute time trial sessions... I may have to revisit the oil cooling approach, but not planning any other changes right now

my biggest concern will be the tire walls at Sebring, etc!!!

Looking forward to ditching the NASA TTA points system... will give me the freedom to play with aero and other variables

GTM stage 2? nice!!! Looking forward to your build!

Do you have a base model? The stupid sport package are tagged with +14 to start!

See below - I had the same issue so I got my base class re-assigned with different options... so below is the secret decoder ring to getting a 370z setup for TTA. Four options. Anyone that wants to use these should get it approved on their own - ie don't assume that my approval applies to everyone. If you don't run NASA TT, this doesn't apply to you... Also, keep in mind that you cannot start from these levels and move down (through smaller tires etc from TTA to TTB) - can only stay the same or move up.

OPTION 1

Quote:

Your '09 Nissan 370Z Sport with a maximum of 300 rwhp on a Dynojet, and minimum competition weight of 3230 lbs, will have a new base class of PTB**/TTB** (fourteen points). Your new base tire size is 265mm. You will not need to assess modification points for power mods or weight reduction. However, all other modifications, including transmission and LSD, that are not standard items on a base trim '09 Nissan 370Z Sport must be assessed points. You must be compliant with the above listed maximum Dynojet hp and minimum competition weight during any tech inspection.

OPTION 2

Quote:

Your '09 Nissan 370Z Sport with a maximum of 320 rwhp on a Dynojet, and minimum competition weight of 3000 lbs, will have a new base class of PTA*/TTA* (seven points). Your new base tire size is 295mm. You will not need to assess modification points for power mods or weight reduction. However, all other modifications, including transmission and LSD, that are not standard items on a base trim '09 Nissan 370Z Sport must be assessed points. You must be compliant with the above listed maximum Dynojet hp and minimum competition weight during any tech inspection.

OPTION 3

Your '09 Nissan 370Z Sport with a maximum of 300 rwhp on a Dynojet, and minimum competition weight of 3100 lbs, will have a new base class of PTA/TTA. Your new base tire size is 295mm. You will not need to assess modification points for power mods or weight reduction. However, all other modifications, including transmission and LSD, that are not standard items on a base trim '09 Nissan 370Z Sport must be assessed points. You must be compliant with the above listed maximum Dynojet hp and minimum competition weight during any tech inspection.

I would like to stay with option 1 since my car is stock, but I really cant compete with no slicks, so I guess I am with the crazies in TTA

travisjb · 08-04-2011, 08:28 AM

Depends on where your WHP and weight are coming in... if you're "competition weight" is above 3300lbs, which is typical for these cars unless heavily stripped, you could tune the car to up to 320 whp and use option 4

... option 4 will allow you to stay TTA, add aero and other mods, and run 275 NT01s (or similar) all the way around... the 20mm smaller tires would give you back a few points and you could spend those along with the remaining 19pts in the class and still stay within TTA

or if you are lighter and running <300 whp, then go with option 1

I don't think options 2 and 3 are going to be relevant to most folks given the challenge of getting down to those kinds of weights...

I have been using option 1... and I was thinking about using option 3 as an alternative setup where I would run lighter and with no aero... no longer relevant given the SC on the way!

ChrisSlicks · 08-04-2011, 09:08 AM

Does "competition weight" imply driver and fuel?

travisjb · 08-04-2011, 09:47 AM

yes, it is what you and car weigh when your car comes in off the track after a run and you are immediately put on a scale... you have to take into account fluids burning off, and claim that minus some contingency (10-20 pounds) as your min weight

RCZ · 08-04-2011, 09:47 AM

Sebring is pretty amazing Travis, definitely try to make it out there. I wish it werent a 4 hour drive for me
