Alrighty so im working on installing my nitrous kit that ive put together and just had a couple quick questions. First, what would it hurt if i didnt put a relay on the purge and heater? I understand i need one on the solenoids for safety but is this that big of a deal on the heater and purge? My second question is what should i gap the tr6s too whenever i install them? Thanks guys

 

I would put relays on them, especially the heater. I gap my tr6s .025-.028. Somewhere in there will be fine. I used to run .030 but had a problem a couple times on the turbo car blowing out the spark. After that I just gapped everything the same and no problems.

 

alrighty will do, if you dont mind me asking what the point of having a relay on them is? It would just be a lot more simple to have it without but i wanna do it right lol. And thanks for the gap info

 

Well the relays are what takes the amperage load, especially on stuff like a bottle heater. Most switches you buy are rated for low amps, bottle heaters have to be on for a while. The longer they are on the hotter the switch gets, eventually leading to failure or fire. The purge you might be ok being you only use it in short burst.

 

aahh i see now...that makes a lot more sense.

 

A relay uses a low current circuit to controll a high current circuit. Switches are rated often to 20 amps but I wouldn't run any where near that current.

Definatly put a relay on the heater and not a bad idea for the purge but I am sure it would be ok due to the short run time.

 

alrighty cool. i went ahead and ordered some relays and harnesses, as well as a ganged fuse panel with ground bus just to make all of it really nice. Any other suggestions?
