What are you guys using to activate your N02 at WOT on a street application (choke and C6 kickdown)?

I have not been able to find any kind of WOT switch that works with my 4150 style carb.
For now I have a N.O. "Pull-type" elec switch (plunger style) but I think I can do better and its a pain to get it setup correctly.
I have checked Summit and Jegs and there seems to be nothing that fits/works.

Maybe there is a WOT electrical switch that works off of MSD6A box. I should check into that.

Is everyone building their own WOT switch setup - or is there another source (besides Summit/Jegs) to look at?
Thanks

I have always used the WOT switch and bracket that Edelbrock makes. Used it on my 4150 based carb, and bought another to use on my Dominator carb. You may need to get a universal bracket since you are running the choke and kickdown though.

Thanks. I'll check out the Edelbrock switches, maybe I missed something.

As I was typing the original post - the "rpm activated switch" idea came to mind, and since posting I have looked at a couple (MSD, Summit, etc). I'm thinking this may be the easiest and cleanest way to mimic WOT activation.

Anyone using one of these? If so, for nitrous what rpm would you set the switch to activate at (assuming max rpm is 6000)?

Would you want nitrous to come on at 3000 rpm?

I'm not sure what a RPM a "mechanical WOT switch" would activate at/correlate to.
