If you weren't spinning horribly on the stock tires, the DRs probably aren't going to cut your times enough to make up for an extra 1000' of DA and the tire height increase (hurting gear ratio). That's a lot of DA to overcome. Once you finish your planned mods, those tires will be just what you...

I may have missed it in the manifold debate. Have you been on the Dyno to get a baseline RWHP figure? If you want 430-450, there are cars out there which have put down numbers in that range bone stock. You may already be there or.close to it. If you Dyno 430, small changes may be all you want...

I have seen a few post in the 2.0 list recently. That post can't be updated as the post owner is no longer available. Can we make this a sticky?

What is the elevation of the track you go to? With DA under 1000', you should have no issues going sub 11.9 with traction. I ran 11.55, and 11.56 in 220ish DA and then 11.32 in -570ish DA on stock tune. I have some cheap 17x9 bullets with a bias ply tire on the back, Forgestar 14s on skinnies on...

The first thing I did was take the car out to the track showroom stock to get a feel for it. I have some old 17x9s with 26" tall MT ET Street bias ply tires and they do the job at the track for eliminating wheel hop. If you hook, you usually won't wheel hop. I did add BMR cradle lockouts and...

What are your 60' times launching at 2500 in 2nd versus launching at 2000 in 1st?

I have 26x11.50x17 Mickey Thompson ET Street bias ply on some old 17x9 bullets. I do not have vertical links.

The list has been updated with all times from this post and a few individual PB posts have been pulled in as well.

Awesome run! Man, that's flying!

I run 26" tall bias ply tires in the back and with my 3.55 gear it would be a perfect setup if I was tuned. For some reason, the stock tune keeps shifting into 7th at the top of the track around 6500 rpm in 6th. Redline is 7400 so not sure if that is part of the tune to help protect the trans or...

12.2 @ 117.78 with 2.0 60'- factory stock in 1200 DA straight off the highway with 140* IATs at the launch. 11.55 @ 121.5 with 1.85 60' - full weight/interior; only mods were 17x9 rear wheels with bias ply DR and 17x4.5 front wheels with skinnies and BMR cradle lockout + braces in 225 DA...

Oh yeah, on stock tires, my method was no water box, quick burnout (~2 seconds) to clean tires and get a bit of heat in them as they don't heat up and stick like a DR with a long burnout. Drag mode and tc/adv track off, launch at 1500, and be ready to modulate throttle as you sense spin coming...

For me and the track I go to, drag mode with TC/Adv Track off was way too much for the stock tires. It was a peddlefest getting a 12.2 in ~1200 DA with no cooldown. The best advice I can give is ppractice the launch and experiment with some throttle modulation right at the 1-2 and 2-3 shifts...

All up-to-date. Sorry for the delay guys.

The best 1/4 mile track in Texas (Houston Raceway Park in Baytown) is closing in April 2022 after the NHRA Spring Nats. The 1/4 mile tracks in Ennis and San Antonio have open track nights/days but they are 4 and 3+ hours away each way respectively from Houston where I live. Most other tracks...

I'm curious, what did the car put down on the Dyno? Your 60' isn't awful considering your tires but if you are spinning beyond that mark, then it could explain some of this. Given your power mods, you are asking a lot of those street tires, stock suspension, and banking on perfect track prep...

I have a 2019 400A with 3.55 gears. It isn't the PP1 but I do have the drive modes which I hear make a big difference. All runs I described above were in drag mode. I have looked much into vertical links or springs so I can't help there. Honestly, if you have good DRs on the back and get them...

I wanted the same as you, to get the most out of the car without voiding the powertrain warranty. I ran my baseline with a 1/2 tank of 93, showroom stock, pirelli pzeros, in 1250 ft DA right off the highway. At the time of the run, my IATs we're ~140*. It ran a 12.2 @ 118 with a 2.0 60'. The...

What trans and gear ratio do you have? I updated the list but want to make sure I note those.

You have a good 1/4 time there considering it's an unprepped surface. My time was on a prepped track with skinnies in front and bias plies in the back. I had MT Sportsman SRs on the front but even being skinny, there was still some uneasiness at the top end because of the bias ply rear so I got...
