I don't know how I missed this build. That is awesome!!!
Sounds like you have a great tune worked out.
I must have missed it, but what cam are you using? Custom grind?
Did you open the ring gaps?

I didnt get any vids but one of the others racers got one of my practice runs, the 9.2 run. I will see if he will email to me. Im hoping that some random person might have got a vid of the true street guys and itll turn up eventually
To the OP congrats on the passes, cant wait to see what it does with steady boost.

I know guys have been fast in the 1/8th, we got a mustang that has been 124.9mph in the 1/8th, but hasn't got a good full quarter hit yet.

More track action went to the track at Norwalk for the LPE nationals and got some runs in. Had some trouble getting to 60 down and the tune straightened out , (1st time to the track with the new boost controller and IC) but got it running good on sunday on aq medium aggresive tune. Pretty low timing considering the iats are in check now that I put on an intercooler. This run is launching on 10psi and ramping in to 18psi.
I was planning on going to the track tommorrow and setting it on kill but I broke the tranny sunday afternoon after this run. Im hoping I have it back together for the lsx shootout.
listening to the annoucer is hilarious, he was cuting down on the looks all weekend
I had an awesome time at the event, tons of badass cars + lots of records broken during the weekend. Geting to see mark carlyle make some runs was crazy. That wheelie was intense, vid doesnt do it justice

launching with 10psi. converter slip on the big end is 4-5%
I was gonna put the travel limiters on the front end, it always 60fts in the 1.2s with those and an aggressive tune. I was gonna start with 12psi on launch and ramp to 24lbs and see what happened.

you were running no intercooler meth? e85? i need this simalr setup in my 73 pantera with lq9
Went to joliet to run true street and make some shakedown runs. Remember I just got it running about 2 weeks ago and didnt have any time for a local track day and decided to go anyhow. Learning how to launch on a turbo car is tricky without a boost controller, but I managed to fig out how.
my 1st pass with the combo, leaving with 0 boost, and on wastegate springs (13psi) netted me a 9.8 @145 with a horrible 1.7 somthing 60ft. It looked like I took off from a stop light then whoosh it took off.
I had 2 more practice runs, basically just trying to fig out how to launch, went 9.7@145 then 9.2@147. still on wastegate pressure
Holley hasnt released boost control yet so I rigged something up that I though would work, it failed, it would start to build more boost then go back to 13psi then build it up and back down. Surging basically. But I left it hooked up anyway.
Heres the results from my 3 runs after the true street cruise. We are required to run 30 miles and go back to the track and we cant do anything to the cars, except lower tire pressure. No hood pops, no adding fuel, no tuning, ect. Then we run 3 hot lap passes
1st: 1.39 60ft (peddled it, cause it pulled a big wheelstand)
5.84 @122
9.05 @153
2nd: 1.61 60ft (my fault, I didnt build enough boost)
6.3 @119
9.58@150
3rd: 1.31 60ft
5.73 @121
8.97 @151 (my first 8sec pass, woo woo)
I wish my 1st run went better cause it would have been an 8.8 I think. The IAT's by the 3rd pass were +245* and the trans temp was 230*
Going to put a boost controller on it and maybe an intercooler too. See how deep it will run into the 8s when I turn up the wick.
