Hoosier QTP's, How many passes left?

[uwntsumrtII]

I've got a pair of Hoosier QTP's. They are worn down to the base of the ribs. How many passes you think are left in them? 12-13 second vehicle.

Here's a pic... for what its worth.

run em until it doesnt hook anymore, or until you cant see where the dimples were. jmo
kinda hard to say how many passes left depends on burnout size

TO the bottom of the hole, then about 20 more. Without doing huge burnouts.
