At what point in the horsepower / ET / speed / pressure game do you need to double-drill and stud the back of our pumps?
I've an early dominator with a place 1/2 droop behind 957 horses without nitrous. 1300 with. Hasn't been down 1/4 mile track with new motor, but hoping for at least 10.0's on motor and will try for 9.0's at least once.
How far you need to push 'em before the double tap is needed?
