We think we can get the converter to let us launch at 2800rpm or so by messing with the pressure at launch. We'll try and find out. Also gonna up the boost a little this time so long as afs stay good. Think we might get close to 140mph this outing.
Mainly we're getting data logs of the trans for circle d to build us the new converter. We're probably gonna end up with a 3500-4000 rpm stall converter and a ligenfelter box for pulling timing to get boost up on the line

Wouldn't 140 put you in the 9s?
I've been having a hellofa time launching mine. Best MPH has been 133 @10.8 with a 1.7 60. Hold 5000 RPM. Launch. Bog. Go.
Same day, 129 @10.8 with a 1.5 60. Only difference was the second pass I left at 3500 and no bog. I would of expected a 10.5-10.4 with the 133.x MPH... if it had left right.
