Does this make any sense?
 

"In addition, for the Stock Eliminator category, two-step activation must be by foot operation of brake pedal, clutch pedal, or pressure switch. Hand release prohibited."


So, let me get this straight. If you have a stick shift car, and the two step is hooked to the line lock button, then you have to move it.
You could put another switch under the brake pedal just for the two step. Then, of course you you would have to put another switch on the shifter in 1st gear, so the two step wouldn't activate when you shift second gear (some of us still have to use the clutch to shift)
This is not to be confused with the switch on the shifter for 3rd gear two or three step activation for the burn out.
Or, I guess you can install a pressure switch on the front brake system hooked to the rev limiter .Of course, that would switch off when you release the line lock button, which brings you back to where we started.
Now you have atleast three buttons instead of the one that's already there.
I wonder if they even thought about all of this before they came out with this bogus rule..????

Mark, Mark. Does NHRA really think about ANYTHING with regard to sportsman racing? You know better than that.
All you need to do is wire another switch to cancel the other 5 switches which is activated by a switch that goes through a momentary switch mounted under the drivers seat. Then hook that to the retard chip in the driver brain which sends shock impulses to remind him to flip the switch! For a schematic on this see your local electronic engineer. Jim

I always thought the line lock had to be alone no matter what the trans? Of course I have been wrong before, according to my wife.

Ya'll are making this way too complicated. Just a put photelectric sensor in each headlight. According to which lane your in, flip that switch. A 12V. magnet will hold the clutch in. When the tree starts down, deck it. When the bulb your pointed at comes on, off you go!! Unless somebody shines a light at you just right going down the track, the 2-step, magnet, and whatever else you want is no longer in the circuit!!

In IHRA the 2-step button is the only function it should have .You cannot have it hooked into the line lock to begin with.ONE BUTTON ONE FUNCTION.Button cannot activate any other item.If you don't believe look on page 76 under linelock in the IHRA 2007 rule book .I thought you guys knew this after we started checking them this yaer .In reality you should have a diff button for every function,like line lock ,burnout, 2-step ect........

danny, That was exactly my point! Jim

Re: Does this make any sense?
 

What about MSD "multi-function" digital ignitions?

I was wondering if they are a good idea but it seems quite complicated.

What if - when the 2-step turns off, it turns on something else?

Can the line loc control the burnout rpm?

Re: Does this make any sense?
 

That's just great. More buttons and switches for no GD good reason.

I thought this was common knowledge:
If you release the button (s) to the two step, the motor will definitely go WFO, but the car will never move until you physically let out the clutch. It's not legal to use a magnet, which should be easy enough to spot, so what is the point of this stupid rule as it relates to stick shift cars?

Re: Does this make any sense?
 

Mark, The rule's intention is for Automatics Mostly, If you think about it you'll see that the rule benefits you. Forget about what the LineLok is doing if you let the clutch go the car is "Leaving".

Re: Does this make any sense?
 

Mark , That really is the point. NHRA knew they could never take the two step button activation away from the automatics and not the stick cars, so they came out with a blanket rule that really has nothing to do with stick shift cars.
Either they have no understanding ....or no cojones. ......Don't know which.
