Stall Converter Trans Brake Powerglide and launch rpm
I'm confused about stall speed, etc. Given the above, what rpm do I want the engine to be at when I launch with or without the transbrake. Thanks.

Ok. 509 Dart BBC, 871 Blower - 10lb boost - CompCams blower grind solid roller, Profiler heads, Advanced Transmission powerglide, new converter but I don't know what the stall speed is. I can find out easy enough, I just haven't asked yet. The old one on the non-blown engine was 3800.

Hey guys when he threw the blower in I don't have a clue what to suggest other than they makes tons of low end torque but I'm lost on this one. Get the cam specs and convertor specs I could help a little more.

1. Have a playback tach, and when you launch the car takes off and the converter flashes, this point is called the flash stall. Also when you shift from 1-2 and the rpms drop this is called the stall recovery.
2. You can check it by pulling the launch chip and putting it up on the transbrake and see what rpms the converter goes to. This result is not the same as the track will be though.

I don't mean to pick or be rude, but I do have a ??. This seams to be a pretty big motor for somebody that doesn't know much about stall convertors. PLEASE don't take that wrong. I'm like everybody else and trying to figure out all the details so we can help. You're just a long ways into this to be asking this question. Again not trying to pick just trying to figure it out.
