9 second Procharger guys, what stall? Just wondering what convertor you 9 second Procharger guys are using? Also, what is your 60' and how streetable is it? I'm wondering if mine is too tight (3600 IIRC). 60' times have been in the 1.62 area, which is sloooow for this car. Used to 60 a full tenth faster on ALOT less power but had a 4200 stall. I street drive the car mostly so I don't want to run a 5000 stall but if the car is hooking and just won't leave any harder I might have to loosen this one up. I'll know more friday night after the track.
Current combo:
408, D1SC (13 psi) 740 RWHP
4L60E w/ PI multi disk 3600 lockup (no brake)
12 bolt w/ 3.73 gear
About 3550 race weight
28X10.5 ET drags or 325/50 MT DR's.
Thanks for any help!

My old combo was almost identical to yours with a PI 3200 multi, 3.42s (12 bolt) and 100 less RWHP, but consistently 60'ed 2 tenths quicker... Ya gotta be careful with the PI stuff in FI cars... You can easily blow past a VERY stout piece of the torque curve and hurt your short time by go up in converter.

What kind of tires do you have with that 1.62?/ Never mind, I just re-read
I have a PY3400 in mine and was worried it was too tight for this combo, although it drives nice on the street which was main goal. I ran a 4000SS Yank with my h/c LS1 and went 1.57-1.59 consistently. Thought about trying it in my 403/D1SC combo but went with this PY3400 for starters.
I am making much less power than you at only 9spi and am hoping to have better 60's than that, at least it feels like it should. I am a little heavier than that also.
Making some runs tomorrow night, I'll let you know. If it blows too bad I may just swap in the 4000SS for some good et's and dragstrip fun!
If you are close to 9's your 60's should be inthe sub 1.40's. Picking two tenths up on the line will get you .4 by the other end easy.

When you run them in high torque FI applications, the actual stall begins to fall quite a ways from the advertised stall... Where as the a few other companies who make converters specifically for FI cars take this into account and you end up closer to the advertised stall... Example... My 3200 Multi Vig was over 4k with 600rwhp/603rwtq.
I think every stall does that. Ive never seen a stall that is exactly its advertised speed. With high hp especially a healty shot of n20 they flash pretty high.
Yeah, actual stall is dependant upon many things (torque, weight, rear gear, FI, n2o, etc)... I'm just warning you to be careful with the PI stuff because they are MORE SO that way than MOST others. I've seen quite a few people with FI and n2o cars over shoot on their converter selection with PI and blow through it... That's aaaaaaaall I'm saying

Went two 10.30's @ 130 Wednesday night with the Yank PY 3400 which drives almost like a stock converter on the street. 60 foots were 1.48 both times. Vids coming.

Too much power vs how tight the stall is.
When adding more power, you really should get a re-stall!
Its one thing to be around a 3500 rpm stall with 400hp, but that same stall might be a 4500-5000 in a higher hp car, it all depends how its built. Also, if you slam it enough, you can break parts, especially on the dyno
