Line lock wiring....

[1QWIKBIRD]

Does the line lock need to have an arming switch? Or can I go straight to a momentary switch?

Not sure why not. Although I'd suppose the arming switch is a safety feature.

No switch

Hot Rod says no.

you can wire it any way YOU want, but i'd think having 2 switches instead of one would be much safer

so does nhra, arm and momentary to pass a real tech inspection

I assumed that but didn't know the regs.

I thought this came up before, but I wasn't sure. The destructions don't mention an arming switch and I've never done one in the past, but this time I will, just to be safe and not piss off tech. I think the relays may be overkill for most situations.

Thanks

[BonzoHansen]

i think they are in this case.

i would definitely have an arming switch especially if the momentary switch is in the open.

Slp's unit only comes with 1 switch. SJM uses the same solenoid, and includes an arming switch for the same price as SLP. That's the reason I recommend the SJM kit over SLP...unfortunately I bought the SLP kit before I knew about SJM.

vinnie you can just buy a push button momentary switch and run it just like the sjm setup. i can take a pic of the sjm wiring diagram if anyone wants

what are your thoughts on doing the line lock through the cruise control? cruise on would be the arm and accelerate would be the momentary. yeah/nah?

[LTb1ow]

Eh...

Nice way to "hide" it inside the car, but I think a tech inspector wouldn't like it.

got a little more than "eh"?

edit: really, why is that justin?

I have no technical basis for the comment, it just sounds like the kind of thing that a strict tech inspector would have an issue with. I don't know if there is anything in the NHRA rulebook that would actually stop you from doing it though.

since the OP's question was answered I have a question that's been on my mind for some time now. I know ppl use line locks for warming up the tires, but can it be helpful when launching? I think pro-stock does it...

you " can " but it takes a ton of practice and a lot of classes dont allow it anyway

[Jam]

yah i bet it takes a lot of practice to get the clutch engagement, line lock toggle, throttle just right.. just wondering. thanks.

[NastyEllEssWon]

i think those are called two steps.


mike ill take a look at that sjm wiring diagram....i still need to wire my linelock up. it might be worth it to do an arming switch

No, a two step holds your engine at a preset RPM so that you aren't launching it at redline.

its too light for pictures to come out right, ill try and scan it sometime this weekend

The thing to do is to use a line lock plumbed into the hydraulic clutch line in conjunction with a 2-step, then leave off a button. Push clutch in, hold button. Button activates the line lock and holds the clutch, at the same time launch limit of the 2-step is activated. Tree comes down, release button, clutch comes out and launch rpm is gone.

Now hit your shifts....

Don't know if its class legal, but it would take the guess work out and allow you to leave on the wood and off a button, very similar to a trans brake in an automatic. You shouldn't need the brakes to hold the car at the line on a stick car, but you could wire in the line lock as well. You could have arming switches for the line lock on the brakes, line lock on the clutch and the 2 step so this way the one button on the shifter could do everything depending on which arming switches are "on".

For burnout: Arm the brakes linelock only or brakes and 2-step (to control burnout rpm).....

For launch: Arm all three or just the clutch and the 2 step....

For scaring the ricers on the street: Just the 2-step.....hahahahhaha

For the old school mechanical linkage crowd, like my Nova......instead of a line lock on the clutch how about a huge magnet? Kinda like this one?

Wire that puppy in with the 2-step and hold on baby.....daddy's gonna haul the mail....

a guy I know who builds these cars for super stock uses a trans brake type button on the shifter( only one button). Two switches would make the burnout box a complicated nightmare.
