I'll be there both days in TT2 or TT1 if nobody shows for TT2.

 

[Don Lariviere]

I'll be there in American Iron.

I'll be in HPDE 3 with hopes to get to 4 and possibly into TT. Gotta be with the cool kids like @PaddyPrix

It’s official - this will be my maiden voyage in TT3 with NASA! Next step is a trip to the dyno.

It's going to be nice seeing some Mustangs out there, I believe I was one of two until Chad blew something up. Lots of smaller cars that you'll reel in on those long straights. -- Oh yeah, and Alessandro was there on Saturday too.

If you've got a passport, might as well get the sign off, I think Toyo gives you some free money for just doing so, and I've heard even more with the TT promo.

If you ran the Super GT Cup without incident with like 20 cars on the track, you should be fine for TT in my book. Running mid-pack you just have to keep an eye out for the TTU guy in the corners, we should keep pace on the straights, but holy moly that acceleration.

It’s official - this will be my maiden voyage in TT3 with NASA! Next step is a trip to the dyno.

Congrats! Here's hoping we replicate our last weekend out at Chuckwalla - - Shake n' Bake!

What's typical etiquette in TT? Slower car stays on-line and TTU guy would go wide or off-line to pass?

Most people only doing a handful of laps means that generally speaking, you don't really have to deal with it more than perhaps the first session, because the pre-grid by laptime has not yet been set. Generally speaking, if you're being passed, stick to the line, and perhaps even give a point if there's any potential for miscommunication. Every so often you'll see somebody on a cooldown lap, and off the line with flashers on, pointing you by on the line, sometimes not, just gotta do it a bit and figure out what people's tendencies are. People in a TT5-TT6 are pretty good about that stuff because they kinda have to be

 

[Frank.JD.Perez]

would love to show up and run tt3 with yall. bit out of the way though

Does anyone have an in-car video of a manual S550 at ACS? I haven't driven this track since my very first HPDE. Not sure what gear to go into and where.

Check @PaddyPrix’s YouTube channel (same name on YT). I believe he has a few laps posted and should be a good comparison since you’re both running the MT82-D4 and assuming your rear gear is the same.

Thank you sir.
I'll check out Mr. Paddy's videos. I think he has 3.55 gears as opposed to my 3.73 but I'm sure it's close enough. I read somewhere to enter the infield in 3rd but that seems too high a gear for that slow a turn

3rd gear into turn 3 should be correct. I’m running 4.10’s and the Tremec is also direct drive in 4th - I hold 3rd through 5 & 6, just touching the top end of the rpm range coming into 5.

For what it's worth, I'm running smaller 315/30/18 tires, which make my tire height like 25.4", a big jump down from the stock 27", so that effectively puts me a lot closer to 3.73 than 3.55. 3rd to 115-120, 4th to almost 160.

I agree with Tom, and for me, I'm in 3rd the whole time with exception to hitting 4th on the two inner straights, exiting turn 6 approaching 7-8, and going through 10-11 which is not really a turn. Grab 4th on the apron/banking and at your power, I think you'd be fine to stay in 4th to the end, probably good to 140 or so as you come into the grandstand which you can just lightly lift and lose some on your turn-in. Turn 9 is iffy for 2nd gear, I have been fighting with it for a bit, but with my lack of a shifter and stuff going on, I don't want to potentially misshift into 2nd, and even when I could, taking that hard right at high rpm makes the rear want to slide out. 3rd will lug it a little bit especially with the G's, but my data shows it's slightly faster, no matter how hard I think I can bang the 2-3 shift.

Edit - Also forgot that since you're a Performance Pack, put your Torsen to good use. Feel free to lean on it in those harder turns, as it applying power to the outer wheel should help you better rotate and pick up some additional exit speed that LSD brokedicks like myself can't. Since LSD just wants to put power down, it'll keep moving both wheels at the same speed, having me fighting throttle and forcing me to understeer and/or overshoot. Enjoy your fancy techmology until I join your cool kid ranks.

Ok, I'll try 3rd gear. I think I was going into 2nd for turn 3 and again into the decreasing radius turn but as it was my first track day, I'm sure I was beyond slow. The less shifting I do, the better. I am no bueno at shifting. Anyone wana sell me an Autoblip

Digital is the way to go.

I have both the Auto-Blip and the Xineering units. Each has their advantages and disadvantages.
Auto_Blip is easier to adjust. Has an on off switch. Less predictable.
Xineering seems to be more predictable. Does not come with a simple on off capability. Add an on off switch for this system is you buy one. Must use a laptop to adjust.

Turn 3 and Turn 9 would be the two places to play with. Assuming that the temps stay solid, perhaps do session 3 forcing yourself into 2nd the whole time, and session 4 skipping 2nd the whole time, and see what wins out? I've been staring long and hard at my Autoblip, still on the fence, I might change my mind.

@flyhalf is my +1

f'n psyched, last minute mods going on and in over the next few nights.

Doesn’t get much better than this....
