Last night I ran 12.75 best time. I’ll post pic of the slip later when I dig it up. I have headers, exhaust, and was running on 275/30/19 Kuhmo PS91. I need drag radials. What is the best drag tire in either a 275/35/19 or 275/30/19?
I read having the car in sport mode does not make a difference, but I disagree. I spun hard every time in sport mode. My best times were in regular mode. I was able to hook up if I just rolled into it. With stickier tires I plan to brake boost.
the DA was also 3000.... that killed my times.

well had a blast at a local big event hosted by 519cars ansd streetstars in sparta ontario running in humid conditons on the friday. Took out all the american v8s that staged against me that night. 392 challenger, pontiac g8 v8 , mustang 5.0 slips to follow.
12.91@112 was my fastest then very low 13,s followed all on a street tire hankook rs2

Semi disappointed, was hoping for lower 12’s but both runs were consistent so I know where the car stands now.
Ran a 12.6 @113 with a 1.9 60’. 275 Indy 500’s aired down to 30psi, first gear burnout for just a couple seconds. Launched from idle. KCLV @ 21, ran 94 octane all week.
Sikky V2’s
Apexi intake kit
Borla exhaust
Didn’t bother softening the rear coilovers cause I had zero traction issues. If it wasn’t so busy I would have tried to launch from a higher RPM cause I had no tire spin. Track was prepped for an event this weekend.
Tempted to go nitrous next year now. I want the 11’s and don’t have faith now I’ll cut .6 off with the tune/intake even with some weight reduction and DR’s.

245 rear drag radials on lightweight 18's will get you into the 1.8 60 foot times leaving off idle. DA is the huge key factor to getting into the 11's.

Finaly getting a chance to post my best time!
Running
PPE headers
Dump valve where the resonator used to be
275/35/19 firestone Indy 500
Spare tire in the trunk with half tank of fuel
i also have the RR Tune but I kept running 1 second slower so I took it off and ran stock tune for this pass. Waiting for the new year to do some data logs and work with RR to get the tune working for me.
2009 ISF with 110 000 miles. Launched at 1200 rpm in right lane and was running a 2018 Mustang GT left lane.

Good times^^^! Your 60ft is what saved you! Do you know if the GT had any mods? 115mp and 12.3 is a supurb time and almost leads me to believe it had something done to it.
Good job again and thanks for sharing!

Your tune slowed you down a second? That doesn’t seem right.

If it was a 2018 with the 10-speed auto then it very well may have been stock. Those A10 cars are super quick stock.

Edit:
here are acouple vids just to show that these arent one offs. Be careful when challenging one of these. The 18 5.0 has 460 hp now and a super fast shifting 10 speed auto.
