Global Time Attack 2018 Discussion
 

So the GTA Super Lap Battle 2017 thread turned out to be pretty good, I figured I'd start this one to provide a place to talk about all the events and progress for the 2018 season, and to build up to Super Lap Battle 2018 which will likely venture into a new frontier of fast Miatas.

Feel free to discuss the rule changes, plans for the season, ideas and strategies etc etc. This is the year that should put to rest the idea that Miatas can't be a fast platform.

The first event is at the end of this month, anyone going? Also cool that the they added another Pro round at NJMP this year as well. My participation is going to be pretty limited this year, had to go back to night shift in order to get a promotion at work and they're stingy with time off for nights.


2018 Schedule Click Here

March 31 - Pro Am Event @ Buttonwillow Raceway Park
May 11-12 - Pro Champ Event @ Road Atlanta
June 3 - Pro Am Event @ Willow Springs (Big Willow)
June 15-16 - Pro Champ Event @ New Jersey Motorsports Park
September 8 - Pro Am Event @ Buttonwillow Raceway Park
November 8-9 - Pro Champ Event - Super Lap Battle @ Buttonwillow Raceway Park

I am shooting to be at the May 11/12 event. Just need to get a new motor built before then. Running in street mod.

Already taking big steps in improvements/changes to the car for this season and have begun testing. I'm aiming to do more test days and then hit a few targeted events rather than just show up to the full schedule of GTA. Something about BW three times in a calendar of 6 events makes me OK with skipping a few events and focusing on development and coming correct for SLB. I do have WSIR on the calendar, haven't run there yet with the new drivetrain so I'm looking forward to returning and the car should be at a really good place in terms of development by then.

Planning on being at BRP at the end of the month assuming things go well next week at CVR.

So. Big news today, new overall record was set for Buttonwillow 13cw today at Round 1. Crazy.

1:37.308 by Will in the Unlimited FWD Vibrant/PZTuning Honda Civic

Amazing time.
So happy for Will and the crew, some of the nicest guys ever, solid program, solid performance.
Well deserved.
Can't wait to see what Will and crew do at WTAC this year!

In other news, huge congrats to Ryan for winning while setting a new PB of 1:47.5 and the fastest lap time of all Limited classes!

We're planning on having OGK ready for Super Lap Battle In November. That will be a tough pull as it's a very complex build with almost all one-off parts. If we can't get OGK together in time, we'll take Vegas, our super clean S1 build with a 6758 and the Quaife sequential. Hope wold be to nip under 1:40 with that. OGK's target is well below that but we'll see if we can get it built, tested and tuned by November.

Temps were higher than ideal, a bit of cloud cover and breeze came out just before the 4th session and brought the surface down to ~105 which is when most everyone ran their fastest laps of the day, including me. Not as good of conditions as SLB but decent. Still working on finding all the speed in the car. More items added to the "improve" list. Still, 1 sec improvement on my PB.



Thanks!

Nice work!

A quick question re the twitchy steering,

I notice some cars/people do this and others don't. I don't except in very high load sections of the corner (or sketchy moments), Wondering if that is a car setup - maybe high/low caster or a car setup up to be more on its nose or purely a driving style do you think?

Alright who's been watching the pictures and videos rolling in from the Supermiata Instagram page?

I'm getting pumped for SLB, will be watching the live stream though since I'm unable to make it this year.

I'm ready to see Supermiata take the field by storm. I'm honestly conflicted about who I want to win more, the SuperMiata or the HyperMiata.

They're in different classes.

I was referring to overall laptimes. Ryan's shown his car very capable even on street tire.

Emilio has 100+ HP more on tap and big hoosiers, so expect his car to be faster.
I'd love to see both winning their classes.

Ryan has a lot more testing time though. Best of luck to 949, their car surely as some huge potential, but my bet is that Ryan will be faster...

Even with Ryan's car being about 150lbs lighter, and with arguably better aero design, he's down 100whp and stuck with 245 200TW street tires.
Vegas is already quicker around Streets of Willow on trash 245s from April/Hyperfest, and we now get to bolt on fresh Hoosiers than are 30mm wider, at each corner. Plus our tweaks from what we learned testing.

The class rules build in several seconds of handicap for Ryan/Hyper. Limited cars and Unlimited cars don't compete, two totally different animals.

Ryan's car also uses Supermiata Xida suspension, we're on the same team here. They're both capable of class wins, like last year, and will both set new standards for Miatas in Time Attack.


Ryan's PB, which I expect him to reset, is a 1:47.5.


Bullet ran 1:46 at SLB 2017, and 1:44 a week later with heavier springs and the same tires.
Vegas is a handful of seconds faster than Bullet was between the extra power, the Quaife sequential, the bigger aero/flat bottom/diffuser and bigger tires.

Power delivery is also different, Ryan's a torquey N/A V6, Emilio is a boosted BP. Ryan might also have the weight advantage, I know he has alot of carbon bits where Emilio still has stock items(doors, fenders, trunk).
Honestly I expect Emilio to be faster. All the aero and Hoho's are a convincing argument. But I think Ryan has a solid shot.
​

Vegas has a dry carbon top and composite doors/fenders/trunk, just like Hyper.
Power delivery? Have you driven an EFR turbo yet?

Hyper is amazing. Its a GT3RS.
Vegas happens to be a GT3 Cup Car.

I'm guessing that if Ryan and I both ran say, 245 A7's, Vegas would still be quicker though the gap would close.

HyperMiata's overall L/D ratio is going to be superior but we still have more net downforce. Bigger wing, flat bottom and diffuser. I'm guessing his 2018 front end has around the same down force as our front end but with probably 1/3rd the drag and weight. Even with our flat bottom and diffuser not validated or fine tuned, that is a lot of surface area on Vegas. One factor that evens out the comparison is that Vegas has almost no exposed dirty undercar bits anymore. That radically alters under car velocity gradient which creates a sharp reduction in overall form drag. Meaning, the flat bottom is a bit of a free lunch in terms of L/D ratio, when viewed in isolation. When viewed as a whole, the increased undercar velocity and huge barge boards help flow over the side and top of the car, making the wing more efficient. We're running the lowest possible AOA on the wang. Instead of AOA, we're letting the span do the work. We have picked up some total drag lbs but that's mitigated by a lower overall L/D ratio from the flat bottom and diffuser. So net, we have way more downforce than we did for 2017 SLB and 2018 UTCC.

I wish Vegas were lighter but as I mentioned on facebook, it's a full tub endurance car with a near FIA cage. All composite panels but steel rear quarters. Most URWD full builds are just using the min amount of OEM tub with tubular frame extensions. Usually fully composite body work and often a simpler, lighter cage.
We should be around 2400lbs wet which is pretty porky. The car we planned for this year was OGK which would likely weigh around 1900 wet when done but we gave up on that early in 2018 when we took a close look at project timelines. So our fall back plan is to take a heavy S1 and add stuff to it for SLB.

We're aiming to go under 1:40. I think Ryan will get the LRWD record in the mid 1:44's.

Without knowing much about the TA world, what are the cars/teams that are likely be be the biggest competitors to Vegas?

There doesn't appear to be solid challenger in the URWD field from what we can tell. Bunch of cars capable of 1:42~1:46 but nothing that appears to be capable of a 1:40. If it doesn't break, we should have a good shot at the URWD win. Our lbs/hp is too weak to reach the URWD lap record though. Crazy to think a 420whp, 2400 lb Miata is too weak. That's modern time attack!
We did a 1:44.7 with 6 heat cycle 245 A7's, 280whp. 2350# and a balky 6 spd and way too soft springs and sway bars. We have another ~500lbs of downforce, 420whp with a much broader torque curve, the correct spring and sway bar rates, the sequential trans and fresh 275/205 Hoosiers.
At 4000rpm we have almost 200 lbs more torque than last year.

3 cars in UAWD that should go under 1:40, one of which should reset the overall lap record for the track. I'm guessing TomO will do a 1:35
The PZ Tuning Civic would easily win UFWD but I don't see it entered. So we could end up maybe 3rd fastest overall. We will give it our best shot.

The PZ Tuning Civic got shipped to Japan after WTAC. They are running the Attack! series at Tsukuba in February so they're definitely not showing up at Buttonwillow tomorrow.

:confused:
Bullet ran a high 44 at SLB.

We ran out of 1:44.6 two weeks later with the same car, older tires and stiffer Springs.

Virtually every comment you have made here and on Facebook have been to discredit or devalue the car. Don't feel threatened of your position at the top of the crazy Miata aero hierarchy Moti. I would suggest however, spending a little more energy to have a running car more often.

You assholes made me sign back into instagram to watch all the updates. Car looks super strong! Can you guys do some live video from the event? Maybe even strap a phone inside on live video? Would be super awesome, thanks.

Posted this on the event SLB thread, it's worth posting here too.

Good luck to everybody competing!!! I have my money on Emilio in Vegas and Ryan in Hypermiata winning their classes. It would also be sweet see both of you breaking the class records as well.

My guess for the new overall record is TomO driving this UAWD Evo:
Attachment 229370

I'd easily compare him to Billy Johnson or maybe even more raw talent?

I don't like it when Daddy and Daddy fight, it makes me feel like i did something wrong.

To be fair he was just making a correction that the car went faster at SLB than Dan originally thought... official results show 1:44.9 as well as the lap video posted on the Supermiata YouTube channel.

| GTA Super Lap Battle Buttonwillow CW13 November 9-10, 2017 RESULTS

With all the awesome upgrades I'm looking forward to some sub 1:40 video with sequential goodness and mega downforce, good luck out there guys.

You got it totally backwards my friend, virtually none of the comments that I made here or anywhere else was made in order to discredit your build, and all of which are made out of my shear concern for your well being... That you choose to get so touchy, defensive and can't take a pretty basic joke (on FB) is pretty disappointing, TBH.
Unlike you, I take the jab at my lack of running car situation as good ol' ribbing between friends, so don't worry, no feelings hurt in the making :rofl:

Not sure what ticks you off, but let's take a look at my commentary -
* I advised you guys to revise the brackets that held the diffuser up along with sound reasoning as to why, simply because I don't want see you destroying your diffuser because they failed, and / or potentially creates a situation on track.
* I voiced a genuine concern over the wing uprights in case they are 1/4" thick. I definitely don't want to see you or anyone else having a massive crash because of a wing failure, especially at the speeds that Vegas is capable of. Again, all with sound reasoning.
* Dan mentioned Bullet ran a 46 at SLB which I can only assume was an honest mistake on his part, because Bullet won with a high 44, I know because I was there to help you to try and achieve that, but I guess a year is long enough to forget that...

What part of this discredits the build?
This joke that a bunch of other people seem to get just fine?

E, go eat some lunch :)

Sorry guys. Getting ready for super lap has been fun but also very stressful. We cool.

/Mandrama

Can i come out of my room now?

I can't. :( I'm building a house instead of a Miata right now. It sucks. Maybe see you dudes at COTA though!

No idea what's that like :giggle:

I'm honestly concerned about your uprights if they are indeed only 1/4" thick... Let me know if you want something done quick, I have sheets of 5/16", 3/8" and 1/2" in stock, if you send me a CAD file I might be able to get my waterjet guy on this in just enough time for you to pick it up on the way to BRP, I can probably even program this for you if you just gave me some basic measurements, we already have the APR bolt pattern.

Here.

We don't have drawings, I don't think there are any. We do have a spare set with Renderos Racing in Hesperia. TC Design made both sets. We are rolling out today around 4pm.

Only option we have is to take them next door to Scarbo and have him cut something quickly. He's got a big water jet, full machine shop (and oh so sexy 5 axis machine).

I'm sure that Tony didn't design these with a GT-2500 in mind.
I encourage you to take any step you can and might be able to help you with it if you run out of solutions, but I'll need measurements immediately (as in, you have my number, get someone with a tape measure on the phone).
I have done FEA on my uprights and the lack of material at the bottom of the uprights is concerning to me, particularly around Riverside and the kink that follows.

What would it take for a Miata to get a 1:37.2?

Give it ~51 hours and you'll find out if the answer is Emilio driving Vegas or if more is needed.

I think he is going to need A6's, 600whp, and a dash of Andrew Brilliant for that 1:37

We have 275/35/15 and 295/35/15 A7s.

1:37 is fast. We'll give it a hell of a shot.

For us, another 150whp or so. I'd rather just build a lighter car though. OGK should do it but that's probably a year or two off. But as stated elsewhere, this is uncharted territory. Bullet surprised us. Perhaps Vegas will do the same.

On Moti's advice, we decided to use the spare set of uprights and sandwich them to the first set. Bolt them together in two spots. Maybe not as stiff as a single 3/8 but a lot stiffer than the single wall strut.

Good luck MT'ers!

Not ideal, but in a situation before with 2x plates of insufficient thickness, I've drilled a hole through both plates with a tapping drill, tapped one side, then drilled the bolt OD through the other plate and countersunk the top, for a flush (on both sides) countersunk joint.

Good call, E.

Wanted to circle back to this.

I think if everything goes well, Emilio and Ryan will take their respective drivetrain classes. Best of luck to the both of them.

Last year the Pro Awesome Evo was being driven by pro driver Jeff Westphal, same guy who got pole position at the 24hr Nurburgring race in the SCG 003 car, probably the most talented driver I've ever seen out at the track. His ability to give chassis setup feedback in a technical manner is like nothing I've ever seen, along with the talent and ability to immediately capitalize on those changes as well. Anyways, their predictive lap timer was on pace to break the overall record when their backup engine let go in between the esses and sunset... they were so close. And now they are back with improvements made to the car.

Can Jam is a super strong entry too but I think they just don't make enough power to get it done. RS Motors ran a 1:40 and won the event last year and have made improvements, their car didn't have anything crazy on it besides the sequential either.

And who knows, Jager might come out of nowhere and surprise some people.

Going to be an exciting event. I don't think that 1:36's will be outside the realm of possible outcomes.

Good luck team. Kick some ass.

P.s its 8.00pm Thursday here already, waiting for results!! :)

Good luck to everyone, I've got the live feed open at work and I'll be keeping an eye on it!

Ouch. There was a Flyin' Miata in Run Group C.

:rofl: "The awd line"

Strong start for the Pro Awesome crew with a 1:40.
Ryan put in a good safe banker lap with a 1:48.7.
I saw E out on the warm up session but not in the timed session, everything okay guys?

Those of you with the ability to watch the stream want to keep those of us that currently cannot watch the stream updated?
