I was thinking this. block all but bottom bulb.
ep-have to lose some that way I would think
Set caster to maximize rollout.
Tried counting years ago...Couldn't do it....I tried blocking the other year and it will definitely slow you down during the day but at night the glare becomes a problem. Didnt have the patience to make it work and gave up.
If you have access to a full practice tree you can go off a 500 pro tree or what I do is screw the top 2 bulbs out and compare RTs. You will see how much you are anticipating the 3rd bulb pretty quick. For me it is between .02-.03.
Just keep getting older. RT problem will fix itself in time. ;^)
if your consistently hitting it .07 then you sure don't want to change what YOU do because your consistant,,,,knock 4 outta the timing that will slow it down
Tried a couple of changes this past weekend but still going red. I have corrected most of the move to the right on launch which is good. I am looking at a larger set of front tires and sending a convertor in to have it reworked for a higher stall.
As to some that suggest I am anticipating the last bulb, I have a video now that shows the third bulb lit, then the car moving, then the pre-stage going out and the red coming on. Maybe not a solid alibi but believe me, I'm staring at that third bulb lit before I hammer it.
Oh hell, I'm 65 now!
if you push the brake pedal much harder. then it takes longer to release the foot.
Okay but how would you push the brake pedal consistently the same on each pass?
I am proof of that, in 17 years of drag racing I have mastered the .050 reaction time. I'm 67 years old,would love to be .015 consistently.
some use pressure gauges. so they brake just as hard every time. but why not just try braking harder as a test. see what happens. before redesigning anything.
Ha! Right now I would settle for your .050! At least that would be some progress....
You can also slow RT when footbraking with a heavier throttle return spring. And as others have said being heavier on the brake will slow it too.
Not sure what your throttle linkage set up is, but if you play with the ratio between your gas pedal and carb, you can slow down your throttle opening.
For example, If you move the attachment point further away from the throttle shaft, you would require more throttle input/travel to go WOT.
I have a sunset racecraft pedal set up in my car where it has multiple holes to adjust this ratio. I dont know if this will slow you .05, but depending on where it's at right now, it may help.

Coming back around to this.
And I appreciate all the suggestions, just never got a chance to try anything else. We had three weekend TnT sessions cancelled at the end of the season by weather, and I decided that the New years race was too rich for me to go with a red-lighting ride.
I have some ideas on loosening the front end but haven't done anything about it yet. I did put a looser convertor in which I was hoping to try out, I probably will test that before doing anything else to the car. As to the throttle, mine is a C/E piece that is pivoted off of the cage crossbar, one connection point for the rod that goes to the carb. I can adjust the pedal up and down some but it doesn't delay the carb opening.

Add clutches in the transmission. This transmission is double O on a 370 pro tree. I added clutches and a slow bracket brake for a 400 pro tree race to set up .020, coming up this transmission will see duty in.
The concept is the same off the foot brake, minus changing the valvebody.
You could do a 10 clutch drum and as many reverse clutches as needed for adjustment.

You can also jack the torque converter pressure up (not to exceed 120 psi) to tighten the torque converter and vice versa (not to exceed 35 psi) for R.T adjustment.
Just put in a FTI PRO Series 4 unit. Think that's a 6 clutch pack. Not sure what's in the reverse.

The older you get the less clutches you need, is my philosophy.

There's an Idea for ya. Call your builder and see what they think about the idea of adding clutches as adjustment for slowing your reaction times. As you can see I'm more than capable of these adjustments for faster or slower RT's.
