How about a good Drag race 904 build discussion

You guys are saying your trans brake does not apply the band when you are staged with the brake on right. You don,t mean it does not apply the band when you are in first gear without the brake on when using it as a manual shift body. Correct?
Does this company make any claims that the model without the band off has a better 1-2 shift.

As I understand it, this is the challenge that the different manufactures face when trying to use band on. They want to protect the roller clutch, but also avoid band overlap on the 1-2 shift.
I talked with Turbo Action jus a couple weeks ago and they told me that they routinely evaluate their competitors brakes and have updated theirs 4 times since it initial release.
They tell they they leave the band on for a longer period of time than most of their competitors do because they believe their is to much chance of roller clutch breakage if the tires would break loose and then grab again.
Yet their manual shift version has no band apply. But they maintain a no band apply has a superior 1-2 shift regardless of brand.
Yet Griner claims to now have the best of both worlds.
Also Tony( hope it's ok if I call that) regarding the chrome moly converter hub.
I had Turbo Action build me a 4600 8 inch pro series converter about 8 years ago.
At that time they offered the chrome moly version with a thicker wall that required a machining off of the ring on the reaction shaft so the converter would go on. Do you recall if you had to perform this modification to yours when you had your converter repaired.
