All I could say to him is that his pregnant wife won't be able to save his du$& ar&e when the car come crashing on him! Some people you can bring to the water but you can't make them drink it.CR

The problem with having common sense is having to deal with the people who do not

Actually, this makes sense in a race car. If the cut-off were on the ground side and metal contacted that terminal or wire in a wreck, the circuit would be complete and current would flow to all the engine electronics and fuel pump. Cut the positive and current to the systems is stopped.

You hear it all the time in the pits with people and there trans brakes.

Rusty2211 is right. Listen any morning in the pits and it sounds like Jurassic park.
Why is there a need to "test" the throttle stop RPM? Every NHRA accepted delay box is digital and the desired RPM is set to a particular value. Have you ever "tested" it and found it to not be the RPM that you set? It sounds like something that is done habitually and has no real useful purpose, sort of like motorcycle riders who cannot let their bikes simply idle at a stop light and have to continually wing the engine. No purpose, just a habit and an annoyance, but a dangerous one in this case.

"Every NHRA accepted delay box is digital and the desired RPM is set to a particular value" Absolutely, completely wrong! Just the opposite is true. You CANNOT set or control throttle stop RPM with a legal delay box!!!!!!!!!!!

Mr Harris, the amount of time a car is on the throttle stop is controlled by a delay box but not the rpms. The rpms while on the stop are controlled by the blades that close, and changing weather conditions can affect what the rpms are.

I will never and have never been under a car without jack stands, but I'm plenty guilty of not being in the car with it running with it sitting on the ground to check timing, look for leaks or whatever else. This year at Houston National event I had a funny noise in the engine after my second TT. I worked on the car for several hours and when I thought I had it fixed, I fired it up and was still hearing a squeaking noise. I had the car on the ground idling with my wife's SUV parked in front of it. I was listening trying to pinpoint where the noise was coming from. Next thing I know an nhra official had jumped a muddy ditch and was walking my way. I knew what was coming so I shut then engine off, listened to the lecture and just said "yes sir" and he left. He wasn't very friendly but hey I was breaking a rule and he did have to jump that muddy ditch to come lecture me. The car was in park and the wife's car was 5 ft in front of it. I think maybe this is one of those deals they are just getting fired up about enforcing the rule for some reason. I have seen plenty of nhra regulars with their stuff running facing the pit roads etc with nobody in the car...sometimes though, like those nice corner pit spots, it depends on who you are if the rules are enforced and what rules are enforced. Stuff like this and the tether rule is why I only run the big show once a year any more.

Then correct Rich67stang, not me. I haven't ever run a car with a throttle stop so what do I know? I know that there are dozens of cars testing something, stall speed, two step setting, whatever. In any case the situation remains the same. Anyone on any morning at any NHRA event can hear countless cars testing whatever it is they are testing and it isn't the stock or super stock cars that are doing it. If the racers are conforming to rule 9:14 as quoted in the original post, then have at it. If not, then don't gripe about being called out for it.

X2, the generator exhaust rule is seldom enforced, I think it is a good rule, just should be enforced EQUALLY, no matter where you are parked or who you are.

Bill I agree 110% but the vast majority of offenders are comp S/C S/G T/S and T/D or go by the Alcohol pits sometime and check out those jokers usually on 1 jack stand and a pair of those cheapie drive up tin ramps. T/S guys are getting just as crazy we'ver seen several of those things fall off of their lift jacks from over zealous motor winging especially down south certain tracks like rockingham and clay city have zero pit patrol and try to say something to one of those guys and right away they want to fight Truthfully I'm getting too old for that ***** so I just go get our german shepherds Lucy and Neko and let themm do the negotiating. ;-)
