2018 Super Lap - Buttonwillow
 

2018 Global Time Attack - Super Lap - Buttonwillow
Nov 8-9

This will be the last Super Lap at Buttonwillow. The premiere GTA event will move to COTA for 2019.
Anyway, who is entered for Buttonwillow? Whatcha bringing?

We are entering Vegas in URWD (Unlimited Rear Wheel Drive) as defending champions. Car is much more developed than last years car.
-25% more power
-35% more torque
-40% wider powerband
-Sequential trans
- Full flat bottom
- Large rear diffuser
- Much higher spring rates and bigger sway bars for better aero platform
- 78" triple element wing. 64" two element last year
- Lower drag, higher downforce front end
- 275 Hoosiers, up from 245's last year
- Unfortunately we also gained about 70lbs from last year but I think the other stuff will hide that just fine

Current SLB URWD record is about a 1:38.5. Current GTA and production car record is a 1:37.2 held by the FWD PZ Tuning Civic. It's about the same weight as our car but has another, wait for it... 500whp and 315/18 Hoosiers
There are three really fast UAWD cars coming, one of which should be capable of a 1:35. So far, none of the entries in URWD look to be a match for a a healthy Vegas. So we're busting ass to get the car ready.
We did a 1:44.9 last year. Hoping to go well under 1:40 and maybe get the GTA RWD lap record.

Ryan will be there defending as LRWD (Limited Rear Wheel Drive). He's done 1:47's there. LRWD record was set by Cody Kischel in a highly prepped 600+whp C6 at 1:44 back in 2015. I know Ryan doesn't just want to defend. He wants that record.
The LRWD field is definitely deeper than URWD. Ryan has his work cut out for him.

It's really cool to see folks from our plucky little community ramping up for this. I'm not that far away but I don't have time to come watch, sadly. Which YouTube channels should I watch for good coverage?

Looks like they are doing a live stream. Sweet. It will be here when the time comes: | Live

Blows my mind that the overall record is held by a FWD car. Good luck this year!

Good luck to all going, hoping to see some new records. I won't be there, couldn't get the time off. Maybe 2019 after the car gets some power drilled into it.


That Limited RWD record that Cody set, I believe the car was just intake/exhaust/tune at the time so maybe 525WHP. But it also had Hankook TD's and a flat bottom since the rules allowed it at the time and TD's were available.

And Will set the Unlimited record at ~750whp, so not quite 900 (latest dynos were up to 850-ish I believe this year?), but yeah still a metric fuck ton of power for a production based track car.

Our URWD entry for 2018.

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 228420

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

Agreed that TomO will probably get the new everything record for 13CW. That car is easily capable and Tom will not leave anything on the table.

I’ll be out by garage 8 towards turn1

Good luck everyone!!

Ryan is on target. 1:48.7 with a banker lap first session. No issues.

Vegas feels amazing on the 275/295 A7's. Minor catch can issue so I aborted my morning practice session. Missing first timed session while we sort the catch can and install the flat bottom.

Catch can fix now better but still filling faster than the drain back to the pan. Modified the check valve, rotated the can to help the oil resist g forces. Will try again at 3.

Aaaaaand it looks like all the live coverage is uploaded on YouTube as well.

Interview with Ryan starting here at 14:37.
