Reaction time

[Joe DeMarzo]

Can you change the reaction time of a stocker by tightening or loosing the front end?

If you loosen the front end will the reaction time be slower because of more travel and visa versa can you speed it up by tightening the front end and having less travel?

Anyone have experience with this type of test.

A pair of polarized sunglasses will kill about .012. Bigger tires, less air pressure (front and back), more brake pressure, staging at launch rpm (as opposed to bumping in and then coming up on the converter), position and stiffness of throttle return springs... there's a million things you can do. For more ideas and details, you can find my guest editorial on bottom bulb reaction times and how to adjust them on www.thisisbracketracing.com

Either that, or the Turismo is still for sale. ;-)

Joe don't sell the car it has one of Kenny's paint jobs on it and it wins.

If it's picking up the front tires while moving forward playing with air pressure will not help much.
Lowering air pressure in the slicks will take care of hundredth easily, 3 - 5 pounds.

Joe I find it hard to believe you even asked this question....

Front end travel will have a big effect on your RT.....and any F-Body from GM is one that can use an adjustable limiter on the upper a-frame....

Limiting front end travel will speed up the RT.....but at some point hook will suffer......

A 3 speed is probably quite a bit different than a P/G and I would guess less effected by front end travel......

I used one on my '69 Camaro in the early eighties.......A nut welded to the upper a-frame and a big bolt going thru it to contact the frame....I messed with it all the time bracket racing......

I can tell for sure there are cars with front end limiters......just look at the pictures......F-Body cars go way negative on camber with no limiter.....If you see a car high in the air with the front wheels at about a ZERO camber angle......it's got a limiter in there....

If your redlighting with full travel..........you have to look elsewhere to slow the RT's........

As good a driver as you are I figured you knew all the tricks.....
