Tans Brake and stall question ????

[thunderace31]

Ok I just used my trans brake for the first time today (Well sort of cars on jack stands in the garage) I just got it back to running condition so I had to try it
Anyway question is I have 3200-3400 stall and when the boost comes up on the brake the eng went right to 9-10lbs of boost and 4000 RPM! Is this normal?? or is my trans/converter broken already??

Now I have never used a brake before and maybe this is a lame question but I just want to make sure all is ok before I go using this set up

Thanks for your help and info in advance

That sounds normal. If you hold it longer it will probably continue rise.

That either means you have more torque than the 3200-3400 was rated against, the converter isn't full of fluid, or first gear is slipping. Stall speed is a function of how much torque the engine makes. A lot of converter builders under-estimate how much torque a Buick turbo V6 makes. They often figure that if the converter will make 3600-3800 on a big block chevy, it'll make 3200 on a Buick V6. Hope you have a really BIG cooler and a trans temp gage.

the stall shouldnt change on the brake it should still flash to the same rpm ..at least in my car..
