dual quad nitrous !!?!!

I answered the OP question before...

You need a fuel system that can handle the carbs and the plate simultaneously, with two different operating pressures. Sometimes it means you need a separate system or it's easier. However the smaller systems are set up to run with a stock type system. So really, you need some fuel gages and regulators and some time to set things up right.

You need to learn how to tune - especially in regard to timing settings. Then follow the kit manufacturer's instructions for your system output.

You may need to replace your spark plugs with something cooler.

You need to buy the bottle venting kit.

You need the steel mounting brackets for the bottle.

I would advise having at least two spare bottles.
