Playing with the trans brake and 2-step.... Just got done playing with the car....
I first started with the 2 step set to 4000 rpm,
It would take about 1.3 seconds to hit the limiter, reviewing the tell tale and it was 9.5 psi!
I backed the 2 step down to 3000 rpm and same deal , just over a second and it was 5.8 psi.
These were quick stabs, I don't want to be on the brake more then a second or two.
Starting line timing was set at 35* via BS3.
This new PTC converter is awesome, they seemed to nail it the first time.
Going to the track on Sunday, weather is supposed to be perfect. It is a race weekend with Pro-Mods and Outlaw 10.5 on Saturday, so the track should be well prepped.
Curious to see how much boost I will be able to leave the line with.
I can't wait!

Hopefully this weekend, someone with a decent camera can get some.
I think it was around 2400 or before it started to push through the brakes.

I am using the Lingenfelter box at have it set at 2800 which gets me to 4 pounds for launch. (Have to work on suspension to launch with more)
Also, it used to take 2.5 sec to get to 4 pound, I now pull 6 degrees with the box and get to 4 pound in .6 secs.

2 step for now, I plan on sending the box to John for the 3 step and other upgrade down the road.
I was going to try to footbrake until staged, and go to trans brake and 2 step when the yellows start coming down.
I would be happy as hell if the track would hold at least 10 psi.

Not yet, getting ready to order a full set of Afco's, I have access to scales though.
I will at least be able to weigh it this weekend.
And individual next week.

Honestly, I would scale it before you hit the track if you can. Depending on F/R, you may be able to add a bag of concrete here or there to make the most of your track day.
Good luck at the track, 10psi launches are going to be a blast!
I'm still a month away from getting mine on the road.
I've been suffering from bdd, (boost defecit disorder) lol...

did you try to hold it back with the 2 step and no trans brake at 2400 or whenever you said it started moving? I ask because Ive got bs3 and no brake and i was wondering if the 2 step would make much of a difference foot braking. seems like it would build boost faster if you could open up the throttle blade all the way sitting at the line.

Honestly I have not tried that with this tighter converter. But I did try that out with the older looser converter I had. It would build 4 psi or so with the 2-step and brake torquing it. I never tried it at the track, but it would work if you did not have a t-brake.
Remember to add timing while on the 2-step with an automatic car. 35-40* seems to work well.
I am getting ready to head to the track, hopefully have some good news to report back tonight.
