i just bought a Pro Systems carb and my NOS activation switch wont work on it. So i will be selling it. I wanna know what you guys are running for a switch.
I have a 4150 style holley but because Pro Systems put all of the extra set screws for tuning the reg switch doesn’t bolt up like it did with my original holley 750.
this is what i have now but wont fit (mine is the same but says NOS instead of jegs)
come buy it for $15
i think this one will work, notice the set screw is the difference:
I’ve always fabricated my own plates for every nitrous application i’ve installed.
yea, it seems like you could drill two new holes to re-orientate the switch
i have a digital one which references my TPS signal. so i am of no use here.
This is what I ran. It was digital WOT switch using the TPS signal, gear dependent controller based on rpm drops, and rpm window switch! Your setup will probably be way more simple, but this box was fucking bad ass.:tspry:
Because he is running a carb I doubt he is running a tps…
You can even route it to the gas pedal for WOT activation. Just make sure it’s mounted right when you do it.
This was the method for any of my super :snky: installs.
Which is why I said that his setup will be more simple, but for others looking for nitrous solutions, this is the way to go!
truth done a few this way. works rather well.
