Positively NO. It is absolutely outrageous that delay boxes would even be considered in Comp. Doing away with the long adjustable switch by having only one switch legal is a great idea. They [NHRA] control the ignition boxes in ProStock that way. You might not be able to control all the devices that will hide delay, but at least the most legal delay switch, the long arm thing ,will be gone.
As far as clutch gap goes, we have only raced clutch cars in Comp and the NO EFFECT comment is true....from .040 to .100. My partner has changed it and not told me, just to see the effect....nothing.
Last but not least, if for some bizarre reason NHRA allows delay boxes, then it only follows that we [clutch cars] can put an air piston cylinder on the clutch pedal. Kenny Reich did it 20 years ago and was told to take it off, but it worked perfect, being triggered by a button on the steering wheel. The use of the clutch was as per normal and the only time the air cylinder was in play was when you pushed the button, as the delay box would be activated when you let go of the button......on the top bulb.
