Right, wrong or indifferent, looks like Auto's yes, and Stick no. I do not know of anyone having one. It may not be a bad idea, but not a rule for a stick car.
Sean See General Regulations 2:11. TRANSMISSION, Automatic Any model transmission (must be same make as car) having same number of forward speeds (O.D. gear not required) and reverse permitted.

Full shift pattern must include park and reverse. Any gear change must occur as a result of an internal function of the transmission or from direct action by the driver.

We used to get asked for that a lot. Usually when you explain it's a stick shift they said OK ----Trevor

Thanks for the input.I got a reply from Div 1 Tech.They said,although it is a good idea, they have never seen it asked for in/on the tech line.
Hopefully that means that it is not required per NHRA |

I`ve never been asked in Tech, besides, most older stick cars never had a clutch pedal starter switch from the factory anyhow.

Not needed for a stick, It is not a good Idea to push the clutch in when starting, puts pressure on the thrust bearing before the oil is circulated through the bearings

hi, you keep this up and NHRA will decide you need a switch. for your information, oldsmobile had troubles with thrust bearings back in 1970 with clutch switch. car had to be in reverse and clutch depressed to start.
just let it go, ok?? no switch is needed !! |
