As for engaging the solenoids, I see a few options and was wanting to know which you all preferred for drag racing. My kit is equipped with a full throttle switch. In-line and before with this switch, I will wire a master nitrous arm switch. The switch can either be a momentary button (such as a thumb switch on the shifter) or a switch on the dash. Which is best for the dragstrip?

It's just a matter of personal preferance and needs.

A fuel pressure safety switch wired in there is a nice safety add-on. Your piston tops might thank you some day.

A lot of people like to use an adjustable RPM switch. Many of these are reffered to as window switches because they switch the system on at a certain RPM and back of at a certain RPM (ie: on at the minimum RPM you want the system to engage and off right before the rev limit).

First off, I used a semi complicated switching mechanism to operate my system. Then I found that I can't shift and hold a button at the same time. I just arm the system and the final trigger is my full throttle switch. That is what I recommend.
