i know this is a little late but i am just getting into this thread and i happen to know a thing or two bout nitrous.....mainly because i run it own my mach
1) i have a different tune and for when i spray nitrous...on that tune i have the timming retarded and i have to run a colder plug and have more fuel going into the motor
2) i run a dry shot on my car and it is safer to prvent blowin the intake off and all the other stories you hear....dry shot safer than wet
so long story short more is not better retard timming more fuel and lower compression...and dont hold it out
intersting thread none the less
with statement 1) i agree that you need to do that on a gas burner of what ever size. especialy with EFI vehicls the timing and fuel will be deliverd with read outs from the o2 censer!
and 2) this is true if you have a EFI or run your carb fat (rich) to start with.
i have "helped" tune n2o cars on the dyno, 2 degree's timing retard for every 50HP shot..........i have yet to see a 50 shot on an atv. i'm ttrying to locate it, but there was a kit out there that had a "tube" type thing included in the kit to either propell the n20 threw the carb eliminating the need for a auxilary fuel pump. i think i saw it on a sand drag web site or something.
so far i have a gas/liquid electric valve (same as n2o solenoid), and a 4-7psi fuel pump, as much -2 or -4 nylon/steel braided line w/ fittings that i'll need. i'm slowly piecing together the components..........i don't see paying $600 for a 10-15 shot for an ATV. the parts can be pieced together for much less (ie what i'm doing now). if a 150-250 shot for a car only costs about 3-500, why should an ATV kit (for single or twin cylinder) cost upwords of $700.........
so far:
4-electric on/off valves (2 for ATV 2 for mud truck) $15
4-7 psi inline fuel pump $7 @ napa
-braided line and fittings are JIC and nylon/steel woven over high press hose $25
some of the other parts you can find off "scam"bay out of broken n20 sets........thats where i'm heading, hahaha
