Big Shot 400 - How to activate

[jreiley]

I bought a car with a bbc and a big shot 400 nitrous system. I don't have all the documentation I really need. The question is when I push the button to start the solenoid, does it stay on until I push it again or do I have to hold it in?

You will have to hold it. I would also put a switch on your throttle where NOS will only come on at WOT.

x2 and I go as far as putting a fuel saftey pressure switch so it has to have atlead 5lbs of pressure.
I have mine setup for both ways, push button and timer, push button is much more fun :D

You shouldn't activate the nos unless you have wide open throttle or it could get ugly. And they say no more than 20 seconds. Go to the Holley website and you can download instructions for the Big Shot kit. Make sure your engine is built to handle nitrous and don't go giving it a shitload right away. Start small and increase the jetting gradually.

Seriously jreiley don't run your 400hp nos more than 10 seconds where ever your at. I would recommend around 5 to 6 seconds right after you launch, sure will save alot of parts.

Make sure the arming switch is mounted on the dash, You don't want to accidentally arm it by mistake during a time trial like someone I know.

That was eliminations and after the front end came down from a 4ft wheely. I still caught the guy and won the round. That was against the Barbarian in that Aglia. Man that was crazy, the front end came down and I hit the gas at the 60' and it yanked the wheels again and off we went. Everybody has to have something dumb they did at the track to be remembered by.lol.
