transbrake and converter stall speed I just purchased a 4500rpm vigilante but it only stalls to 4000rpm on the transbrake. Vicki at Precision said specifically it would stall to 4500rpm on the brake and flash to around 4800rpm on the bottle. She had my dyno sheets to look at as well, would could be causing my converter to only stall at 4000rpm? Please help out guys. I also had a tci ultimate street fighter 3800 that would only go to 3000 on the transbrake. I just had the tranny rebuilt, clutch plates etc. Any ideas? Something in the valve body bad possibly? It is a manual valve body.

I don't know how much you spray, but with even a 100-150 shot it is going to flash more than 300 RPM's, probably more like 800-1000 RPM's.
From my understanding, heat, weight, torque, and apparently air quality...I'm not sure, just from what I have read. Thus I leave selecting a converter to the guys that do know, and like you, I give them every detail I can. Regardless, you can still come out a little short, but I wouldnt worry about it, now if yours was slipping like mine (24% +) then I'd be worried.

Verdad Gallardo Ok, I can see that. Just didn't think a 1K feet DA difference would change a stall by 500 rpm. I'll have to remember to think of that at the track next time when using the transbrake and 2-step...Thanks for the reply!
