You can take Griners release times to the bank! ....Several years ago when fast trans brakes were just coming into being,Bob Maze at Transmission Specialties ,built a valvebody"dyno" to check performance claims against his own products. .....At the time I used both Bob's and Griners products,and knew which was the fastest, Bobs"dyno "confirmed it!........Griners TH400 valve body is like no on elses. ...It uses an all billet body with huge passages and only one shift ball that's about 1/2"in dia.. ....It also has an internal solenoid with a very large exhaust port. ....If you are serious about racing on the .4 pro tree and using what you already have ,you are wasting time and money if you use anything but the Griner brake. ....Tom
