Finally..... I was able make some passes. I am disappointed in the runs, for the most part.
Just to review whats been going on for the past three weeks, I did get the converter back in time to go to the Flashlight drags. I picked the converter up out of the box and shook it to check for 'slag'. This will now be a common practice for any torque converter installation. Well, I actually heard two pieces of 'slag' rolling around in the thing and I finally lost all my cool with FTI. Once Greg called me back, he said he welded that converter himself and their was no way anything could be in there. Greg instructed me to install the converter anyway so I did. Shortly after the install and run in, the trans began leaking fluid out the converter seal. So, we didn't make the flashlight drags. I kept adding fluid now and then and beat the crap out of the tranny for next couple days. The trans is holding now with no issues. Line pressure is 210psi at idle and 290psi maxed out.
Greg was going to send me a new seal and some machined converter spacers and thank goodness I called him the next Thursday cause he had totally forgot to send the stuff. I went to a local auto parts store and bought a $3 seal. This seal did not fit any tighter on the converter hub than the other one so I mic'd it. It was 1.869". The correct od is 1.875". After speaking with Justin at FTI, he was absolutely certain this would not cause the leak.:bang
So, I installed the new seal and re-installed the trans. The new seal did not leak. We were loaded up and ready to go last weekend, but, the weather would not cooperate.
We made it to the track Friday evening and they rained out. Yesterday, after a very cold night sleeping in the race trailer, we were able to run.
This first pass was pure hell on the trans. The air wasn't bad, but, I was having a heck of a time getting up on the turbo and then the timing system didn't work. So, after all that heating, I had to start over. Somewhere during the pass, the converter seal began leaking again. I also was a little late on the shift and ended up turning the thing to 6600RPM. The trans temp gauge pegged at 250*F and I thought I was done. This pass netted a 1.5957 60' with a 6.5043 ET at 109.47MPH.

We let everything cool down and I ran it on a jack to see the leak. The leak had stopped so we wiped everything down and went for a second pass. The second pass was a waste. I couldn't get spooled up. It's not worth posting the video, but, I did get it spooled about half track and ended up trapping at 99MPH. lol
On the third pass, the air was changing and I got 'er to boost up really good. Shortly after I launched, a trans cooler line blew off and I made a nice u turn at about the 60' mark.

The fourth and final pass was pretty much a waste as well. Some very nice and helpful racers pulled clamps off their fuel line so I could clamp the 4 barbed Summit Push Lock fittings. We wiped everything down again and added 4 qts of the $6.30 tranny fluid and headed out for another pass. She boosted pretty decent, but, this was the first round of eliminations so I let it go trying to cut a light. My 60' was 1.6115. When I hit high gear, she made a hard move toward the guardrail and I had to lift. Once back straight, I got back in it and ran a 6.8535 at 100.14MPH.

When I got back to the pits, the trans had been leaking fluid badly which I think started when I hit high gear causing the move to the guardrail. From what the fellas at the drag strip are telling me, she's blowing fluid out the vent??
I know my converter is too tight. Obviously, I need to be able to build boost quicker. I don't know if a converter can be built that will allow say 3000rpm of stall and still be stout enough??
