im going to be jumping into a car that has a pro transbrake vs mine which has a standard brake.does anyone know roughly delay box difference between the two?
I will have no test hits in this car just a couple qualifiers then race so im trying to be at least in the ballpark.

Being that car is so much faster than yours I think you will have more to worry about than what you put in the box. Just put your normal number in it and see where your at or compare your number to the regular drivers number and put something in between in it on the 1st hit

steve seeing we can only go 6.10 the car is only a tenth or so faster than my car so I don't think im going to notice much difference

I found about .020 difference between a King pro brake and a Coan standard brake.

.030 has always been the rough number in my head for the difference between a Standard and Pro brake although all different brands may vary.

If it were me and this were possible, I'd make some practice tree hits along with the person who regularly drives the car to see how much you should add/subtract from their regular delay.

About .020 is the difference i always saw. That's swapping trans in the same car.

thanks everyone!!!
