Anybody runing TTD in NASA TT?

What kind of setup do you run? Is RX-8 competitive in that class?

I would love to join you in that if I could. I'm not sure I am going to be ready until the following summer though. What is allowed in this class?

the only thing that I have been thinking about is coilovers, and possibly some stickier tires. i have anti-roll bars already, plus a front shock tower brace.

it depends if you want to run in a stock class, or go up a class.

Yea, we were looking at that at lunch. I think we put together 2 or 3 different very good possible TTD setups.


What sways are you running?

I'm going to assume your setup is your secret? What region are you running in?EDIT: probably Texas, derrrr.

Are you going to run Texas region? I figure if you've already start prepping for it now, you're going to start next season?

I may see you at Gratten next year. I love that track. I would be running this year except the lack of funds.

I would like to run at Gratten too, hopefully I can bank enough track funds this winter to have some serious fun next summer.

We are trying to go do some baseline on the car before we started tuning it, but the weather is not cooperating...sigh...

I've been doing DEs since last year as prep. I started with the car mostly stock (stock width tires, intake, exhaust, ms springs struts) slowly adding a piece here and there as skill increased. I'm in the advanced run group with the DE organization I drive with now and the car has a few more mods on it but for the most part isn't too tweaked.

Intake +1
Exhaust +1
CoilOvers +4 +2
265/35 tires +4

My 2 largest point penalties are for the wider tires and the coilovers. I'm getting sways fairly soon which is another +2. Leaves me with 5 points that I don't know how I want to use yet. I'm planning on putting on the MS body kit and have no clue how that will affect the points so I'm just going to let the points sit. It could add 7 points depending on how they class it so I just don't know.

Are you going to run street or DOT R tires? If DOT R, which one? Because depending on the UTQG rating, you may be assessed more points.

Bridgestone RE-01R. Street non R compound tires. Just slightly behind the Yoko AD07s. Damn good tire though. DAMN good. Plus I really don't see the point of being faster than other people if I have to change something I can't run on the street. I do have 2 sets of wheels but the "street" set is mainly for the bling factor.

Not sure how Texas runs, but a lot / most run R compound at Mid-Ohio if not all.

My friends and I did an experiment with his stock E46 M3 (333hp) on very good streets vs my pretty much stock RX8 (some small suspension + Hoosiers) vs a modified Honda Prelude (287 supercharged HPs + suspension + hard R-compound). We ran Mid-Ohio. We were all pretty experienced drivers on the track. M3 was most experienced at M/O. I had been there one other time and Prelude was a first timer there. I was able to edge out the Prelude by only a second and maybe at best 1.5-2s beat out the M3.
Tires are a very big deal ...especially if you are not running the R's.

I have othe experiences such as Mosport with a street tired Viper running equal times. All I saw down the back straight was his dust, but I was able to catch him up right before the straight started again. We were both in the Advanced group so it was not because he was a bad driver either....I believe the difference was tires.
Anyone else have similar experieinces?

I dont, nor do I run with anyone that uses R-comps as of now, but I have seen many similar situations play out just because of the way this car brakes.

I would suspect r-comps would be a huge deal in TT though.

^ you can run them in TT, but you need to basically have no other modifications or just go ***** out and run TTU or TTR

Its +5 but if you have wider tires there is a penalty there too. My tires are 265 which is already a +4. I still think the setup I have should make me competitive in TTD here. You can always check your times against what the front runners in your class in your region are running. That should give you a good idea how well you stack up.

BTW, an E46 runs in TTC stock. Your RX8 would still be classed in TTD. The Prelude ... have no clue what that'd be classed as because of the aftermarket super charger.

I also run in the advance run groups. I don't run R-compounds but I can still also turn laps faster than cars with R-compounds and more HP. I'm not saying it doesn't make a difference but driver still trumps all.

Avenger, do you ever make it up to MSR near DFW? I'd like to get back into doing some track days, and might end up converting my B Stock RX-8 over to a TTD car in the next couple of years. I'd be curious to see how a B Stock car on V710s (my car currently racks up +14 according to NASA's rules) stacks up against your car.

By my reckoning, you could build a pretty competitive TTD car, starting with an RX-8:

Shocks: +3
Springs: +2 (you could have a pretty sophisticated set of double-adjustable coilover shocks built that would still avoid the +7 assessment)
Sway bars: +2
Exhaust: +1 (no power, but shave 35+ pounds out of the car pretty easily)
245 width V710s: +10
Total: +18 <--- Still in TTD, and can take another 19 pounds in weight loss figuring the alternate min. comp. weight with that last point

Add in some of the "freebie" mods (shorter final drive, lightweight clutch and flywheel, remove a/c and radio), and you'd have to ballast to make min. weight. I'm 205#, and based on what my car weighed in track trim at the Houston SCCA National Tour, I'm only about 5# over the minimum competition weight as it is right now. Get a lighter driver and/or start ripping out free components, and it's time to add ballast.
