front tire size worth in delay
 

I have ben having a problem with being able to go red I need to know what tire size is worth in roll out delay I have 26" tires on and I need about .010 would a 28" tire work?

Re: front tire size worth in delay
 

All else being equal, they should be worth.....something.
Sorry for the nonspecific answer, but the question is that way ,too.
BTW, if you're on a pro tree, shouldn't you be over on the .90's forum?

bottom bulb full tree I know a larger tire will help slow down reaction time, added roll out i was hoping others have tried different tire sizes and found out what size is worth what

Worked for me.... dad needs to do the same thing right now... @ the local 1/8 mile track he only runs 18psi in the fronts (26")

Lower the RPM

Re: front tire size worth in delay
 

I'm a little confused (not an uncommon state) but why would a tall tire slow reaction time?

Stock drivers are known for the quickest and consistent reaction times and most of us run tall tires.

Not a slam against you electronic guys.

Mark,
Why would you think he is a .90 racer. Even if he is what difference should it make the driver has a problem.

913,
I think the tire will help but not very much. The problem you will run into is it may help a race or two, then you will get comfortable and start going red again. I bottom bulbed for over 20 years. When the Led's came out it screwed me up. I fought it for 5 years. I built 3 different cars. Different e.t. range. The problem always came back. I won a lot of races and finished high in the points too, but the problem always came back. Not saying I gave up but I moved on. I found a home in Delay Box/.90 racing for now. I may come back one day, but will have to build a "BETTER MOUSE TRAP"
Some things we tried on the last 2 cars.
Tires-front and rear
RPM
Blocking
Timing
Rear Gears
Transmissions
Trans gear ratios
Convertors(Lots of them)
Headers
Header collectors
Traction bars
Weight (LOTS OF IT)
Weight in different locations
Mufflers
DeTune the motor which worked somewhat but did effect consistancy and then when you get a heads up you are out to lunch.
De Tune- with Cam Timing, different oil, More oil, We ran a holley and tried it on 2 bbl. etc, etc, etc,

We were trying to kill the initial move of the car but keep it fast and consistent.

Good Luck.

Experiment with lowering air pressure in front tires, lowering rpm a little at time.

You get a longer "run" at the beam before you knock the stage light out and start the clocks..

Chip, because he said he said he was ABLE to go red. That sounded like .90 talk.
Anybody can go red on a full tree.
Nothing personal. Just trying to get him in the right place.

I know what you mean about the LED lights. I wasn't "the driver " when they first came out.
Then I built a car with an adjustable button. I was trying to get away from deep staging with the autostart. I'd adjust the button and then end up right back where I was , usually red. No real explanation for it.
I've since gone back to deep staging and a solenoid to set the rpm at the last second. I seem to be on the right track with that.
