The optimal n20 setup, Safest and most effecient way to go about n20 Options

[crankyelbow]

I've searched pretty heavily on here and read lots of great info... but I'd like to discuss what would be the *optimal* n2o setup. Its been hinted here and there, buried within threads mostly containing "I want some nawzz!".. I'd really like to contain all that great info within one thread specifically about the optimal SAFE n2o setup.

Heater, bottle opener, larger exhaust (per expected power output), wet is pretty much a given... the real question here is fuel management. How to add the right amount of fuel at the right time and still maintain the optimal setup when there is no spray. Timing, injectors... what is really the best way to reliably handle an n2o setup?

Emanage? S-AFC? Something else? Perhaps something that can manage a dual stage setup and fuel...?

Wideband required?

I'd think the "optimal" setup would be something that can control timing and fuel and recognize the n2o and adjust accordingly... this must exist but I'm not sure of what specific device can achieve these results.

It would be nice to nail down a bulletproof setup for each of the common motors... my personal interest is the 5sfe

I'd really like to see how a solid n2o setup compares to a turbo on paper - performance, reliability, safety, cost... n2o will of course add up as you use it, but for those who do not wish to run big power all the time, or are perhaps satisfied with the output of their setups as they are but want that power boost safely available... n2o may be just the way to go.

n2o 5sfe...

get a wet kit
make sure everything is up to spec (full tune up)
(and most importantly the usually ignored fuel filter)

a 35 shot is too small... start with a 50 shot, and work up to a 75 shot....

You need 1 step colder plugs, in copper (don't use platinum or iridium), and it's possibly best to use a slightly reduced plug gap...
make sure your timing is set to stock (10* BTDC) or possibly retard it by 2* if you are running a 75 shot
You don't need any intake side upgrades (the nitrous will take care of intake flow)
Do get a header and a full header back exhaust
Don't skimp on the safety aspect, you need a window switch, an air fuel safety switch and a WOT switch, plus an arming switch to make it a safe setup
purge is optional (And looks cool i guess)
never spray on anything less than 93 octane

If your clutch is old, your clutch may die on your first spray (if you don't have a window switch, the car may just rev up through redline, hit fuel cut and blow the motor...this is why a window switch is essencial).

never spray 5th gear, or spray longer than 15 seconds.

edit: no need for a fuel controller, if you want ot tune it, do it on a dyno, at a fixed bottle pressure (get a pressure regulated bottle heater) and use nitrous/fuel jets to tune the mixture...

make the line between the nitrous solenoid and the nitrous nozzle twice as long as the fuel line from the nitrous solenoid to the nitrous solenoid (so if the kit comes with 15" lines for both fuel and n2o, either get a 7" line for fuel or a 30" line for n2o) ... this will eliminate a 'lean' spot on nitrous activation...

edit2: you're auto... get your auto tranny flushed and auto filter replaced... you may want to switch to synthetic tranny fluid... and you need to get (or make sure you have) an oil cooler on your transmission before you start spraying... tranny coolers for autos are like clutch upgrades for manuals...

that's it , if you have more questions, ask...

My goal here is a stickyable n2o post... please add anything of value

I am particularly interested in an engine management system that will aleve the "less than optimal" daily tune required in an n2o setup... things must be detuned all the time for those few seconds of bliss (colder plugs, timing retard), but there must be a way around this?
